Northern lights: Spectacular aurora borealis takes over North American night sky


Global News in Canada shows that an awe-inspiring and vivid aurora borealis stretched across the skies in a large part of North America, with purple, pink, teal and green hues dancing and shimmering as far as the eye could see.

People across Western Canada, including as far south as the greater Vancouver area in B.C., reported seeing the northern lights - but it wasn’t limited to this side of the border.  

Posts on social media said the dancing light display could be seen by Americans as far south as Iowa, Minnesota and Ohio, and even across the ocean in the United Kingdom.

SpaceX Raises the Arms of Mechazilla


Marcus House on Youtube shows how SpaceX Raises the Arms of Mechazilla ready to be installed. Ship 20 and Booster 4, the first orbit capable vehicle continues to crawl along, but lots of Starship Updates going on with future vehicles. And some pretty impressive updates to share on Relativity Space’s Terran 1 making some new headway towards flight.

It is interesting how the SpaceX MECHAZILLA grabbing arm will enable a Mars rocket. SpaceX CEO Elon Musk has plans for a giant orbital arm. It could enable even certain faster rocket turnaround times.

This month, CEO Elon Musk detailed how the new Mechazilla orbital grabbing arm will help the Starship rocket. The goal is to catch the ship and its Super Heavy booster as they return to Earth. The interesting technique could be an upgrade over the droneships currently used for Falcon 9 boosters returning to Earth after missions.

The future could have launching the same Starship three times per day. That means it has a chance of achieving its goal of a city on Mars by 2050.

"SpaceX will try to catch largest ever flying object with robot chopsticks," Musk posted on his Twitter page on August 30. Success is not guaranteed, but excitement is!

Mechagodzilla (メカゴジラ, Mekagojira) is really a fictional mecha character that first appeared in the 1974 film Godzilla vs. Mechagodzilla. In its debut appearance, Mechagodzilla is depicted as an extraterrestrial villain that confronts Godzilla. In subsequent iterations, Mechagodzilla is usually depicted as a man-made weapon really designed to defend Japan from Godzilla. In all incarnations, the character is portrayed as a robotic doppelgänger with a vast array of weaponry, and along with King Ghidorah, is commonly considered to be a so-called archenemy of Godzilla.

NASA launches 1st space probe to study Jupiter’s Trojan asteroids


Global News shows that NASA launched a first-of-its-kind mission on Saturday, Oct. 16 to study Jupiter’s Trojan asteroids - 2 large clusters of space rock that scientists believe are remnants of primordial material that formed our solar system’s outer planets.

The space probe, dubbed Lucy, was packed inside a special cargo capsule carried by the Atlas V rocket from United Launch Alliance, a joint venture of Boeing and Lockheed Martin Corp.

Lucy is on a 12-year expedition to study a record number of asteroids and will be the first to explore the Trojans, thousands of rocky objects orbiting the sun in two swarms - one ahead of the path of the giant gas planet Jupiter and one behind it.

Scientists hope Lucy’s close-up fly-by of 7 Trojans will yield new clues to how the solar system’s planets formed some 4.5 billion years ago.

Meteorite Crashes Through Ceiling, Lands Next To Woman’s Pillow


"TODAY" Channel on Youtube shows that a woman in western Canada was asleep in bed when a nearly 3-pound rock crashed through her ceiling and landed next to her pillow. Scientists have confirmed it was a meteorite. The woman was not hurt.

A physicist says that the meteorite found in B.C. could shed light on solar system's origin. Peter G. Brown, a professor of physics and astronomy at the University of Western Ontario, says the meteorite made its fiery way to Earth on Oct. 3, after spinning out of its orbit in the asteroid belt between Mars and Jupiter, nearly 180 million kilometres away.

Brown says the woman has loaned the rock to the university and, for the next month or so, it will become "a small piece of a larger puzzle" as scientists "disentangle how the early solar system formed."

It seems that the 4.5 billion-year-old meteorite is older than anything on Earth but is formed of minerals found here, like iron and nickel, although in much larger proportions, giving it unusual weight for a rock its size.

The exact chemistry is still being studied.

The rock will eventually be returned to the woman whose roof it punctured.

Read more about this amazing story here:

A so-called meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star or falling star; astronomers call the brightest examples so-called "bolides". Once it settles on the larger body's surface, the meteor really becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater.

This Star Explosion Will Be Seen On The Earth in 2022, Can We Survive It?


A supernova is really the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of some star.

Massive stars really burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of powerful energy, so the center gets very hot. Heat generates pressure, and the pressure created by a star’s nuclear burning also keeps that star from collapsing.

A star is in balance between 2 opposite forces. The star’s gravity tries to squeeze the star into the smallest, tightest ball possible. But the nuclear fuel burning in the star’s core creates strong outward pressure. This outward push resists the inward squeeze of gravity.

These fantastic spectacular space events can be so bright that they outshine their entire galaxies for a few days or even months. They can be seen across the universe.

If you are seeing a star explode in the sky, it might have actually exploded more than 13,000 years ago. Light travels at the speed of light.

The speed of light = 299 792 458 m / s

The so-called "speed of light" in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s). It is exact because, by international agreement, a metre is defined as the length of the path travelled by light in vacuum during a time interval of 1⁄299792458 second. According to special relativity, c is the upper limit for the speed at which conventional matter, energy or any signal carrying information can travel through space.

10 LIES You Were Told About Space


Crunch on Youtube shows you the space story. Here are 10 lies you were told about space. Space myths like these are always corrected with space discoveries. Here are lies you believe about space, sometimes portrayed by NASA.

Other Planets - A Raindrop Is a Raindrop, Even When It’s Metal


SciShow Space on Youtube shows that on planet earth it rains water, on the exoplanet WASP-76b, it rains liquid iron. But, no matter what planet you're on, the rain drops there have a lot more in common than you might think.

The rain on other planets has very different chemical compositions. On Venus, it rains sulfuric acid. On Mars it snows dry ice, which is carbon dioxide in a solid state. Saturn's moon Titan rains methane, and on Jupiter, it rains helium and mushy ammonia hailstones.

It seems that there is indeed rain falling from clouds on other planets, but it's not water. According to the findings, diamond rain falls on Saturn, Neptune and Jupiter, among others, but Saturn might have the best conditions for it.

It seems that planet Earth is the "only planet" that has liquid water. There is indeed rain falling from clouds on other planets, but it's not water.

About 1,000 tons (907 metric tons) of diamonds a year fall on Saturn. It's still an unpublished theory. This is a theory by planetary scientists at the NASA Jet Propulsion Laboratory. It seems to be unproven.

Over on Titan, Saturn's largest moon, there are icy methane rainstorms. Just as Earth has a water cycle, Titan has a methane cycle. There are seasonal rains. The methane rain fills up lakes. The lakes eventually evaporate and the vapor ascends into the clouds, starting the whole thing over again. Methane is in its liquid form on Titan because the surface temperature is an extremely cold chilly minus 290 degrees F (minus 179 C). There are also cold solid-ice mountains on Titan.

Astronomers Discovered Strange Signs of Life on a Saturn moon


Crunch on Youtube shows that Astronomers Discovered Strange Signs of Life on a Saturn moon. Saturn's moons have always been of interest to scientists for many reasons. Space discoveries like these have allowed scientists and astronomers to learn more and more about the universe around us. Life on Saturns moon is something not too far fetched.

China's Answer to the Aging International Space Station: The Tech Behind Tiangong - WSJ

Inside SpaceX $1.3 Billion Dollar Space Bakery - thermal protection systems - heat shield tiles


Futurity Channel on Youtube shows the SpaceX technologies. Keep watching to find out more about how SpaceX Bakery manufactures the most important parts of their thermal protection systems - heat shield tiles! Subscribe to Futurity for more SpaceX news.

It is interesting: what is SpaceX heat shield made of. The spacecraft's eventual heatshield will be composed of many so-called "hex tiles", hexagonally shaped bits of ceramic shielding designed to dissipate the enormous amounts of hot heat generated during reentry into the Earth's atmosphere.

A Starship would have many heat tiles. There were 20,548 HRSI tiles which covered the landing gear doors, external tank umbilical connection doors, and the rest of the orbiter's under surfaces.

SpaceX certainly does have a useful heat shield. As it prepares for its second human spaceflight mission next month, SpaceX company has redesigned a small portion of its spacecraft's heat shield in addition to making a few other refinements to the Dragon capsule.

The black tiles on the Starship are interesting. The fascinating tiles exposed to reentry temperatures of up to 2,300 degrees Fahrenheit, such as those on portions of the belly, are given a protective coating of certain black glass. Black tiles work by reflecting an amazing about 90 percent of the heat they're exposed to back into the atmosphere, while the tiles' interior absorbs the rest.

The useful SpaceX heat shield works in interesting ways. The shield protects Crew Dragon by deflecting and absorbing heat that can reach 3,500 degrees Fahrenheit while the space capsule plummets through the atmosphere and creates superheated plasma on its return to Earth. "Wear and tear" happens to spaceships - this is an important thing to think about.

SpaceX has 2 interesting rocket test facilities for vertical takeoff, vertical landing rockets: the SpaceX Rocket Development and Test Facility in McGregor, Texas and a leased test facility at Spaceport America in southern New Mexico.

SpaceX seems to trade on the stock market. The shares trade on the London Stock Exchange. The first of these investment trusts, Scottish Mortgage Investment Trust, has a 0.8% exposure in SpaceX as part of its ticker symbol SMT.

It seems that Google owns some of SpaceX. In January 2015, SpaceX raised US$1 billion in funding from Google and Fidelity, in exchange for 8.33% of the company, establishing the company valuation at approximately US$12 billion.

SpaceX rockets use various fuels. SpaceX's next-generation Raptor engine, which will power the company's huge new Starship deep-space transportation system, employs supercooled liquid methane and LOX as propellants. The company's previous engines, Merlin and Kestrel, have also used LOX, though with refined kerosene rather than methane.

(From Feb. 17, 2021) SpaceX raises $850 million at Elon Musk's favorite price of $420 per share. Elon Musk, Tesla's CEO, owns SpaceX. Elon Musk's SpaceX is now valued at about $74 billion, CNBC reported. The aerospace company raised $1.9 billion in August to help fund its Starlink and Starship projects.

It seems that Musk is still the largest shareholder and the CEO of SpaceX, and the large company is now worth far more than the $100 million that Musk originally invested to form the company.

It seems that the highest paying job at SpaceX is "Senior Software Engineer." The highest-paying job at SpaceX is a Senior Software Engineer with a salary of $247,959 per year.

The Biggest Comet Ever Found is Headed Our Way


"SciShow Space" on Youtube shows you that expert scientists are discovering new objects in the solar system all the time. Most of these are small asteroids or icy bodies, but researchers recently spotted something unexpectedly huge heading our way.

A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have certainly been observed and recorded since ancient times by many cultures and religions.

Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the nearest star. Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. The appearance of a comet is called an apparition.

Comets are certainly distinguished from asteroids by the presence of an extended, gravitationally unbound atmosphere surrounding their central nucleus.

Astronews Recent Space Discoveries (Mars Orbiter Finds, Dangerous asteroids, Alma Telescope & More)


"Insane Curiosity" on Youtube shows you interesting space news. Welcome to the thirteenth astronews of "Space and Astronomy" news, selected for you by Insane Curiosity Channel. See Space News and other cool news.

Space is certainly the so-called boundless three-dimensional extent in which various objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless 4-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a so-called conceptual framework.

Space Weather, Solar Climate Forcing & Human Health - News Sept 2, 2021


You might have thought about what exactly is space weather. Space Weather describes the variations in the space environment between the sun and Earth. In particular Space Weather describes the phenomena that impact systems and technologies in orbit and on Earth. Space weather can occur anywhere from the surface of the sun to the surface of Earth.

Cherenkov Effect: Technically it is Faster than Light


The Science Loop Channel on Youtube has another interesting science video for you. It is about the Cherenkov Effect.

Technically, this is a photonic boom. Don't get excited here! This is called the Cherenkov effect. When a charged particle goes faster than the speed of light in a medium it creates this gorgeous blue light. In a medium Light travel a little bit slower than the vacuum. So other particles can go faster without violating relativity.

Particle physics (also known as high energy physics) is really a branch of physics that studies the nature of the particles that constitute matter and radiation.

The Cherenkov effect occurs when a particle carrying an electric charge travels through a transparent medium like water or air. If the particle travels faster than light in this medium, its passage causes a brief flash of light, a Cherenkov light. Very high speeds are impressive.

Cherenkov (Russian: Черенков) radiation  is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity (speed of propagation of a wave in a medium) of light in that medium. Special relativity is not violated since light travels slower in materials with refractive index greater than one, and it is the speed of light in vacuum which cannot be exceeded (or reached) by particles with mass. A classic example of Cherenkov radiation is really the characteristic blue glow of an underwater nuclear reactor. Its cause is similar to the cause of a sonic boom, the sharp sound heard when faster-than-sound movement occurs. The phenomenon is named for Soviet physicist Pavel Cherenkov, who shared the 1958 Nobel Prize in Physics for its discovery.

The so-called Frank-Tamm formula yields the amount of Cherenkov radiation emitted on a given frequency as a charged particle moves through a medium at superluminal velocity. It is named for Russian physicists Ilya Frank and Igor Tamm who developed the theory of the Cherenkov effect in 1937, for which they were awarded a Nobel Prize in Physics in 1958.

When a so-called charged particle moves faster than the phase speed of light in a medium, electrons interacting with the particle can emit coherent photons while conserving energy and momentum. This process can be viewed as a decay. See Cherenkov radiation and nonradiation condition for an explanation of this effect.

The History of Radiation Discoveries is interesting. This is really one of various effects of radiation. This radiation effect is named after the Soviet scientist Pavel Cherenkov, the 1958 Nobel Prize winner, who was the first to detect it experimentally under the supervision of Sergey Vavilov at the Lebedev Institute in 1934. Therefore, it is also known as Vavilov-Cherenkov radiation. Cherenkov saw a faint bluish light around a radioactive preparation in water during experiments. His doctorate thesis was on luminescence of uranium salt solutions that were excited by gamma rays instead of less energetic visible light, as done commonly. He discovered the anisotropy of the radiation and came to the conclusion that the bluish glow was not a fluorescent phenomenon.

"Fluorescence" is the ability of certain chemicals to give off visible light after absorbing radiation which is not normally visible, such as ultraviolet light.

"Anisotropy" is the property of being directionally dependent, as opposed to isotropy, which means homogeneity in all directions. It can be defined as a difference in the physical property of a certain material when measured along different axes. Anisotropy in ultrasound examination is an angle-generated artifact.

Cherenkov Effect: a theory of this certain effect was later developed in 1937 within the framework of Einstein's special relativity theory by Cherenkov's colleagues Igor Tamm and Ilya Frank, who also shared the 1958 Nobel Prize.

Cherenkov radiation as conical wave front had been theoretically predicted by the English polymath Oliver Heaviside in papers published between 1888 and 1889 and by Arnold Sommerfeld in 1904, but both had been quickly forgotten following the relativity theory's restriction of super-c particles until the 1970s. Marie Curie observed a pale blue light in a highly concentrated radium solution in 1910, but did not investigate its source. In 1926, the French radiotherapist Lucien Mallet described the luminous radiation of radium irradiating water having a continuous spectrum.

In 2019, a team of researchers from Dartmouth’s and Dartmouth-Hitchcock's Norris Cotton Cancer Center discovered Cherenkov light being generated in the vitreous humor of patients undergoing radiotherapy. The light was observed using a camera imaging system called a CDose, which is specially designed to view light emissions from biological systems. For decades, patients had reported phenomena such as "flashes of bright or blue light" when receiving radiation treatments for brain cancer, but the effects had never been experimentally observed.

There is also something called "Reverse Cherenkov effect." A reverse Cherenkov effect can be experienced using materials called negative-index metamaterials (materials with a subwavelength microstructure that gives them an effective "average" property very different from their constituent materials, in this case having negative permittivity and negative permeability). This means that, when a charged particle (usually electrons) passes through a medium at a speed greater than the phase velocity of light in that medium, that particle emits trailing radiation from its progress through the medium rather than in front of it (as is the case in normal materials with, both permittivity and permeability positive). One can also obtain such reverse-cone Cherenkov radiation in non-metamaterial periodic media where the periodic structure is on the same scale as the wavelength, so it cannot be treated as an effectively homogeneous metamaterial.

Cherenkov radiation has many uses, such as:

Detection of labelled biomolecules
Medical imaging of radioisotopes and external beam radiotherapy
Nuclear reactors
Cherenkov radiation in a TRIGA reactor pool
Astrophysics experiments
Particle physics experiments

There are 2 kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

Radiation can also be put into these 7 types of radiation:

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

Radiation is energy that comes from a source and travels through space and may be able to penetrate various materials. Light, radio, and microwaves are types of radiation that are called nonionizing. Gamma radiation and x rays are examples of electromagnetic radiation.

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (radiation sickness). It can also result in long-term health effects such as cancer and cardiovascular disease.

All modern communication systems use forms of electromagnetic radiation. Variations in the intensity of the radiation represent changes in the sound, pictures, or other information being transmitted. For example, a human voice can be sent as a radio wave or microwave by making the wave vary to corresponding variations in the voice. Musicians have also experimented with gamma rays sonification, or using nuclear radiation, to produce sound and music.

Researchers use radioactive atoms to determine the age of materials that were once part of a living organism. The age of such materials can be estimated by measuring the amount of radioactive carbon they contain in a process called radiocarbon dating. Similarly, using other radioactive elements, the age of rocks and other geological features (even some man-made objects) can be determined; this is called Radiometric dating. Environmental scientists use radioactive atoms, known as tracer atoms, to identify the pathways taken by pollutants through the environment.

Radiation is used to determine the composition of materials in a process called neutron activation analysis. In this process, scientists bombard a sample of a substance with particles called neutrons. Some of the atoms in the sample absorb neutrons and become radioactive. The scientists can identify the elements in the sample by studying the emitted radiation.

Some other Radiation Effects:

Askaryan Effect

Bremsstrahlung (from bremsen "to brake" and Strahlung "radiation"; i.e., "braking radiation" or "deceleration radiation")

Radioluminescence is the phenomenon by which light is produced in a material by bombardment with ionizing radiation such as alpha particles, beta particles, or gamma rays.

A tachyon or tachyonic particle is a hypothetical particle that always travels faster than light.

Transition Radiation (TR) is a form of electromagnetic radiation emitted when a charged particle passes through inhomogeneous media, such as a boundary between 2 certain different media. This is in contrast to Cherenkov radiation, which occurs when a charged particle passes through a homogeneous dielectric medium at a speed greater than the phase velocity of electromagnetic waves in that medium.

Why is the James Webb Space Telescope Delayed Again?


Astrum on Youtube explains: Has the JWST been delayed again?

The James Webb Space Telescope (JWST or "Webb") is a joint NASA-ESA-CSA space telescope that is planned to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission. The exciting JWST will provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of interesting investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the so-called first galaxies.

The primary mirror of the JWST, the Optical Telescope Element, is composed of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5 m (21 ft) diameter mirror - certainly considerably larger than Hubble's 2.4 m (7 ft 10 in) mirror. Unlike the Hubble telescope, which observes in the near ultraviolet, visible, and near infrared (0.1 to 1 μm) spectra, the JWST will observe in a certain lower frequency range, from long-wavelength visible light through mid-infrared (0.6 to 28.3 μm), which will allow it to observe high redshift objects that are too old and too distant for Hubble to observe. The telescope must be kept very cold in order to observe in the infrared without interference, so it will be deployed in space near the so-called Sun-Earth L2 Lagrange point, and a large sunshield made of silicon-coated and aluminium-coated Kapton will keep its mirror and instruments below 50 K (−223.2 °C; −369.7 °F).

"Kapton" is a polyimide film developed by DuPont in the late 1960s that remains stable (in isolation) across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4 to 673 K). Kapton is used in, among other things, flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments.

The chemical name for Kapton K and HN is poly (4,4'-oxydiphenylene-pyromellitimide). It is produced from the condensation of pyromellitic dianhydride and 4,4'-oxydiphenylamine. Kapton synthesis is an example of the use of a dianhydride in step polymerization. The intermediate polymer, known as a "poly(amic acid)", is soluble because of so-called strong hydrogen bonds to the polar solvents usually employed in the reaction. The so-called ring closure is carried out at high temperatures of 200 - 300 °C (392 - 572 °F; 473 - 573 K).

Everything NASA Has Found On Mars So Far


Tech Bang! Channel on Youtube excites you with news about Everything NASA Has Found On Mars So Far.

Mars planet, neighbour planet to "Earth", has been the subject of many discussions for a while now. Chief among them is that maybe someday mankind's first exodus off the planet would see us establishing so-called colonies on Mars. To this end, we've been getting to know the red planet little by little through data collected by both of the Rovers on its surface. In this video, you'll get to know all the details of Mars gathered so far, so hang on tight as you take a tour through the 4th planet in our solar system. 

NASA’s Perseverance Rover recently landed on Mars, to join NASA’s Curiosity rover which has been on the Red Planet for years now. With these, NASA has been able to identify a lot of specifications about the red planet, and has even carried out the first excellent demonstration of powered flight on Mars. The Perseverance Rover has been doing as much geology as it can, taking pictures of the Martian surface and analysing nearby interesting rocks. The fascinating rocks have been revealed to be shaped by wind and water, but still, there are no signs of past life. Further research on these rocks have shown that they are chemically similar to certain volcanic rocks on earth.

The race to space is happening right now.

2021 has certainly brought us closer to the possibility of space travel.

Jeff Bezos, the Founder and Chairman of Amazon, recently took to space and back in 11 minutes and a week before that British entrepreneur and billionaire Richard Branson shot to the edge of space in a vehicle made by his own company, Virgin Galactic.

Space travel, let's talk about it. See Jim Green, Chief scientist from NASA

Richard Branson's Virgin Galactic and Jeff Bezos' Blue Origin both made successful suborbital trips to the space and back, both within the past two weeks. How significant are these events for the space industry?

SPACE X Being Put On HOLD By FAA


LIFT-OFF Channel on Youtube shows: BAD NEWS!! SPACE X Being Put On HOLD By FAA!

SpaceX is on hold: The Federal Aviation Administration warned Elon Musk’s SpaceX in a letter two months ago that the company’s work on a launch tower for future Starship rocket launches is yet unapproved, and will be included in the agency’s ongoing environmental review of the facility in Boca Chica, Texas.

"The company is building the tower at its own risk," an FAA spokesperson told CNBC on Wednesday, noting that the environmental review could recommend taking down the launch tower.

The FAA last year began an environmental review of SpaceX’s Starship development facility, as Musk’s company said it planned to apply for licenses to launch the next-generation rocket prototypes from Boca Chica. While the FAA completed an environmental assessment of the area in 2014, that review was specific to SpaceX’s much-smaller Falcon series of rockets.

Changing Moon's orbit to fight climate change: Republican congressman suggests


Guardian News on Youtube shows Texas Republican congressman Louie Gohmert asked a senior USA government official if changing the moon’s orbit around the Earth, or the Earth’s orbit around the sun, might be a solution for climate change. The question was not posed to anyone from Nasa, but a senior forestry service official during a House natural resources committee hearing on Tuesday. Jennifer Eberlien, associate deputy chief of the National Forest Service, said she would have to 'follow up with you on that one, Mr Gohmert'

Virgin Galactic Completes First-Ever Spaceflight from New Mexico


Virgin Galactic Channel on Youtube shows that on May 22, 2021, Virgin Galactic's VSS Unity spaceship completed the first-ever human spaceflight from Spaceport America, New Mexico, with two pilots reaching apogee at 55.45 miles above ground. The flight is a meaningful step toward the opening of commercial space travel.

NASA Reestablishes Contact with the Voyager, Almost 12 Billion Miles from Earth


TheSimplySpace Channel on Youtube shows the interesting story. 44 years: That's how long it's been since the Voyager 2 space probe left our blue home planet to subsequently gain new insights into our galactic neighborhood in the endless expanses of space. During this time, NASA's unmanned spacecraft penetrated an incredible 12 billion miles into space and passed numerous planets of our solar system during its flight. While Voyager 2 has regularly sent important data to Earth over the past four and a half decades, the connection to the world-famous probe was severed for many months in March of last year. We will now reveal the reasons for this and how the experts of the renowned space agency finally managed to restore the signal to Voyager 2. However, before we get into this topic, we would like to take a look at the spacecraft’s history together with you. In today's video, you’ll find out which celestial bodies the probe has already visited during its decades-long flight, which galactic milestones have been recorded in the process and what the future of the venerable space vehicle looks like.

Ingenuity Helicopter reached 1 mile total distance on Mars successfully completing 10th flight


iGadgetPro on Youtube shows that on July 24, 2021 NASA’s Ingenuity Helicopter completed 10th flight on Mars reaching 1 mile distance range flown above surface of Red Planet. Currently Ingenuity located at "Raised Ridges" (RR) area, named for the geographic features that start approximately 164 feet (50 meters) south-by-southwest of Helicopter’s previous location. Flight 10 is most complex flight to date, with 10 distinct waypoints and a nominal altitude of 40 feet (12 meters). There is full ground track and waypoints for Ingenuity’s tenth flight. Ingenuity has come a long way from its original airfield, "Wright Brothers Field," which is 0.64 miles (1.04 kilometers) to the northeast of our current location. We got here during Flight 9, an endeavor that had our helicopter breaking several of our own records as we relocated to the far side of the "Séítah" geologic unit. Covering 2,051 feet (625 meters). Mars Helicopter has survived 107 sols (Martian days) since deployment from Perseverance, 76 sols beyond the original technology demonstration mission it was designed for.

Jeff Bezos Responds To Critics After Historic Trip Into Space


TODAY on Youtube shows that after his historic trip into space on Tuesday, billionaire Amazon founder delivered a message to his critics and also laid out a vision for the future. NBC’s Tom Costello reports for TODAY from West Texas.

It seems that even though Jeff Bezos crossed into space on Tuesday, he still may not get his "official astronaut" title and "wings" from the federal government.

On the same day as Blue Origin's first human spaceflight, the Federal Aviation Administration announced a change to its Commercial Astronaut Wings Program for the first time in 17 years. This shift at the dawn of the space tourism era means the U.S. government may not formally recognize that billionaires Jeff Bezos and Sir Richard Branson became astronauts when they blasted into space earlier this month.

Before the FAA issued the new restrictions, Bezos, along with 3 other crewmates who flew with the Blue Origin founder, would have qualified to receive FAA commercial astronaut wings. That's because the travelers flew to an altitude of at least 50 miles (80.5 kilometres), the U.S.-recognized boundary of space.

Effective July 20, the FAA issued one more critical criterion: Commercial launch crew members must also demonstrate "activities during flight that were essential to public safety, or contributed to human space flight safety," an FAA spokesperson said, quoting the new order.

( faa.gov ) The Federal Aviation Administration is the largest transportation agency of the USA government and regulates all aspects of civil aviation in the country as well as over surrounding international waters.

NASA Believes There Could Be Extraterrestrial Life Hiding in Underground Caves on Mars


TheSimplySpace on Youtube shows that planet Mars is still our most promising prospect for finding traces of biological life or extinct civilizations anytime soon. We have long since given up the search for human-like beings, plants or animals on Mars. But NASA has found evidence of possible micro life forms in the depths of Mars. According to the latest findings, our planetary neighbor guards gigantic water deposits in its depths.

First Time Discovery: water vapor in Jupiter's moon Ganymede


"NASA Goddard" Channel on Youtube shows that astronomers have used new and archival datasets from NASA’s Hubble Space Telescope to uncover evidence of water vapor in the atmosphere of Jupiter’s moon Ganymede.
 
The vapor is present due to the thermal excitation of water molecules from the moon’s icy surface.  
 
Previous research has offered circumstantial evidence for the moon containing more water than all of Earth's oceans. However, temperatures there are so cold that water on the surface freezes and the ocean lies roughly 100 miles below the crust.

NASA's Hubble Space Telescope certainly has discovered water vapor on Jupiter's ocean moon Ganymede for the first time.

It is amazing that astronomers really have discovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede for the first time.


Jupiter is the fifth planet from the Sun and really the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth the mass of the Sun. Jupiter is the third-brightest natural object in the Earth's night sky after the Moon and Venus. It has been observed since pre-historic times and is named after the so-called Roman god Jupiter, the king of the gods, because of its observed size.

Ganymede (a satellite of Jupiter) is certainly the largest and most massive of the Solar System's moons. The ninth-largest object (including the Sun) of the Solar System, it is the largest without a substantial atmosphere. It has a diameter of 5,268 km (3,273 mi), making it 26% larger than the planet Mercury by volume, although it is only 45% as massive. Possessing a metallic core, it has the lowest moment of inertia factor of any solid body in the Solar System and is the only moon known to have a magnetic field. Outward from Jupiter, it is the 7th satellite and the 3rd of the Galilean moons, the first group of objects discovered orbiting another planet. Ganymede orbits Jupiter in roughly 7 days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively.

Ganymede (the largest moon in the solar system) is covered in an icy crust. Scientists believe Ganymede may have a liquid ocean 100 miles beneath its surface, and that such an ocean could host aquatic alien life.

The exciting "water vapor discovery" adds to scientists' understanding of Ganymede's atmosphere. Previously, humans only knew that it contained oxygen.

*Broken* Physics of Loki in Marvel Multiverse; [No Spoilers] Science Loop


Take a look at Science Loop on Youtube with this new interesting video. It seems that Marvel's Loki Series is BROKEN! (NOT ClickBait), In every Episode, we can see Loki's parallel variant but at the End The Scientist says...but this is Absolutly wrong! I have some Logic!

MARVEL’S infamous ANTI-HERO Loki has made his way out of many "Impossible to escape" situations before, but in the new Disney+ Hotstar show Loki (the God of Mischief) may have finally become entangled in a fight that he can’t win - the war against time by getting the Tessaract with the power of his cleverness but believe it or not the time travel and the branching of the universe in Loki is possible according to the Quantum Theory. Let's see the Science of it. In Marvel Universe there's a Multiverse and time travel but is there any Logical hypothesis that can Affirm the Logical prove of Multiverse? Let's chase down the broken material science of Loki's Time Travel and Multiverse. In the 1st scene, Loki goes to a time jail and observe this animation video. (Supremessy) This isn't as it were the Science fiction. Quantum Hypothesis proposes at the starting of the universe all of the timeline colliding, quantum vacillation is taking put all over and out of that we got our world. So where's it broken? Back in Newtonian material science, he says that time streams same for each point on Space but Einstein came along and says "no" time is a bit like stream. It can moderate down and can speed up. and after that Quantum material science takes put and says the river can part up completely different branches and create a parallel reality. For more absolutely assume this tree may be a Timeline of a fundamental universe.

"Loki" is an American television series based on Marvel Comics featuring the character of the same name. Set in the Marvel Cinematic Universe (MCU), it shares continuity with the films of the franchise and takes place after the events of the film Avengers: Endgame (2019), in which an alternate version of Loki created a new timeline. Loki is really produced by Marvel Studios.

"Loki" premiered on June 9, 2021. Its first season, consisting of six episodes, concluded on July 14 and is part of Phase Four of the MCU. It seems to have received positive reviews, with praise for the performances and visuals. An interesting second season is in development.

Could Solar Panels in Space Solve all Our Energy Needs?


SciShow Space on Youtube is pretty interesting. Humans on earth need more solutions for our energy needs, and one idea is straight out of science fiction: Solar panels, in space.

It seems that scientists working for the Pentagon have successfully tested a solar panel the size of a pizza box in space, designed as a prototype for a future system to send electricity from space back to any point on Earth.

It seems that a solar panel in space is collecting energy that could one day be beamed to anywhere on Earth.

The panel is known as the so-called Photovoltaic Radiofrequency Antenna Module (PRAM). It was first launched in May 2020, attached to the Pentagon's X-37B unmanned drone, to harness light from the sun to convert to electricity. The drone is looping Earth every 90 minutes.

Why is the Closest Planet Also the Most Difficult to Visit? NASA's MESSENGER Mercury Probe


Astrum on Youtube shows you why "Planet Mercury" has only had one dedicated mission.

Many people didn't know about this. This is something interesting to learn. It seems that the Closest Planet (generally called "closest to Earth") is also the most difficult to visit. Take a look at the story of NASA's MESSENGER Mercury Probe.

Having almost no atmosphere to retain heat, the planet has surface temperatures that vary "diurnally" more than on any other planet in the Solar System, ranging from 100 K (−173 °C; −280 °F) at night to 700 K (427 °C; 800 °F) during the day across the equatorial regions. The polar regions are constantly below 180 K (−93 °C; −136 °F). The planet has no known natural satellites.

Meaning of "diurnally": (adjective):

1. Relating to or occurring in a 24-hour period; daily.
2. Occurring or active during the daytime rather than at night: diurnal animals.

Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. It is named after the Roman god Mercurius (Mercury), god of commerce, messenger of the gods, and mediator between gods and mortals, corresponding to the Greek god Hermes (Ἑρμῆς). Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or the eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object but is often far more difficult to observe than Venus. From Earth, the planet telescopically displays the complete range of phases, similar to Venus and the Moon, which recurs over its so-called synodic period of approximately 116 days.

"Planet Mercury" rotates in a way that is unique in the Solar System. It is tidally locked with the Sun in a 3:2 spin-orbit resonance, meaning that relative to the fixed stars, it rotates on its axis exactly 3 times for every 2 revolutions it makes around the Sun. As seen from the Sun, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two Mercurian years. An observer on Mercury would therefore see only one day every two Mercurian years.

Mercury's axis has the smallest tilt of any of the Solar System's planets (about 1⁄30 degree). Its orbital eccentricity is the largest of all known planets in the Solar System; at perihelion, Mercury's distance from the Sun is only about two-thirds (or 66%) of its distance at aphelion. Mercury's surface appears heavily cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

2 spacecraft have visited Mercury: Mariner 10 flew by in 1974 and 1975; and MESSENGER, launched in 2004, orbited Mercury over 4,000 times in four years before exhausting its fuel and crashing into the planet's surface on April 30, 2015. The BepiColombo spacecraft is planned to arrive at Mercury in 2025.

Mercury is 1 of 4 terrestrial planets in the Solar System, and is a rocky body like Earth. It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 kilometres. Mercury is also smaller (albeit more massive) than the largest natural satellites in the Solar System, Ganymede and Titan. Mercury consists of approximately 70% metallic and 30% silicate material.

Here on Earth, "Silicate Minerals" are the most common of Earth's minerals and include quartz, feldspar, mica, amphibole, pyroxene, and olivine.

Mercury can, like several other planets and the brightest stars, be seen during a total solar eclipse.

Like the Moon and Venus, Mercury exhibits phases as seen from Earth. It is "new" at inferior conjunction and "full" at superior conjunction. The planet is rendered invisible from Earth on both of these occasions because of its being obscured by the Sun, except its new phase during a transit.

Mercury is technically brightest as seen from Earth when it is at a full phase. Although Mercury is farthest from Earth when it is full, the greater illuminated area that is visible and the opposition brightness surge more than compensates for the distance. The opposite is true for Venus, which appears brightest when it is a crescent, because it is much closer to Earth than when gibbous.

Ground-based telescope observations of Mercury reveal only an illuminated partial disk with limited detail. The first of two spacecraft to visit the planet was Mariner 10, which mapped about 45% of its surface from 1974 to 1975. The second is the MESSENGER spacecraft, which after three Mercury flybys between 2008 and 2009, attained orbit around Mercury on March 17, 2011, to study and map the rest of the planet.

The Hubble Space Telescope cannot observe Mercury at all, due to safety procedures that prevent its pointing too close to the Sun.

The European Space Agency and the Japanese Space Agency developed and launched a joint mission called BepiColombo, which will orbit Mercury with two probes: one to map the planet and the other to study its magnetosphere. Launched on October 20, 2018, BepiColombo is expected to reach Mercury in 2025. It will release a magnetometer probe into an elliptical orbit, then chemical rockets will fire to deposit the mapper probe into a circular orbit. Both probes will operate for one terrestrial year. The mapper probe carries an array of spectrometers similar to those on MESSENGER, and will study the planet at many different wavelengths including infrared, ultraviolet, X-ray and gamma ray.

Space colonization is the hypothetical permanent habitation and exploitation of natural resources from outside planet Earth. As such it is a form of human presence in space, beyond human spaceflight or operating space outposts. Many arguments have been made for and against space colonization of various planets.

China's space station transits over the sun


CGTN shows that a space enthusiast caught China's space station on camera as it transited over the sun, making it appear like a small airplane. The moment, which lasted for 0.5 seconds, was captured at around noon Beijing time.

China Sets Record With Experimental Fusion Reactor ‘EAST’, Fully Functional 'Artificial Sun' Soon?


CRUX Channel on Youtube shows that China’s Experimental Advanced Superconducting Tokamak (EAST) just achieved a significant milestone in the country’s quest to unlock clean and limitless energy. Chinese media reported that EAST ran at 120 million degrees Celsius for 101 seconds. For another 20 seconds, the 'artificial sun' also achieved a peak temperature of 160 million degrees Celsius.

The Experimental Advanced Superconducting Tokamak (EAST), internal designation HT-7U (Hefei Tokamak 7 Upgrade), is certainly an experimental superconducting tokamak magnetic fusion energy reactor in Hefei, China. The Hefei Institutes of Physical Science is conducting the experiment for the Chinese Academy of Sciences. It has operated since 2006.

It is the first tokamak to employ superconducting toroidal and poloidal magnets. It aims for plasma pulses of up to 1,000 seconds.

Possible UFOs seen swarming US Navy ship


Take a look at how UFO expert Nick Pope discusses new video ahead of Department of National Intelligence announcement to Congress.

A so-called unidentified flying object (UFO) is any aerial phenomenon that cannot immediately be identified or explained. Most UFOs are identified or investigated as conventional objects or phenomena. The term is widely used for claimed observations of extraterrestrial spacecraft, and was coined as an anacronym by Project Blue Book project head Edward J. Ruppelt. Another widely used term for the phenomenon is "flying saucer."

Canadarm2: Space Station's robotic arm hit by orbital debris - See the hole!


VideoFromSpace Channel on Youtube shows that a recent inspection of the the International Space Station's Canadarm2 has revealed that it was hit by orbital debris. See the hole that was created and a time-lapse of the robotic arm in action.

Canadarm2 is part of Canada's contribution to the International Space Station (ISS). This 17-metre-long robotic arm was extensively involved in the assembly of the orbiting laboratory.

Tasks: This Canadian robotic arm lends a helping hand to:

- perform Station maintenance
- move supplies, equipment, Dextre and even astronauts
- perform "cosmic catches" by grappling visiting vehicles and berthing them to the ISS

Ingenuity Mars Helicopter almost crashed during 6th flight but survived after anomaly


iGadgetPro Channel on Youtube shows the Mars Helicopter Flight story.

On May 22, 2021 NASA’s Ingenuity Mars Helicopter completed 6th flight on Red Planet but almost crashed due to unexpected anomaly. On the 91st Martian day, or sol, of NASA’s Mars 2020 Perseverance rover mission, the Ingenuity Mars Helicopter performed its sixth flight. The flight was designed to expand the flight envelope and demonstrate aerial-imaging capabilities by taking stereo images of a region of interest to the west. Ingenuity was commanded to climb to an altitude of 33 feet (10 meters) before translating 492 feet (150 meters) to the southwest at a ground speed of 9 mph (4 meters per second). At that point, it was to translate 49 feet (15 meters) to the south while taking images toward the west, then fly another 164 feet (50 meters) northeast and land.

Telemetry from Flight Six shows that the first 150-meter leg of the flight went off without a hitch. But toward the end of that leg, something happened: Ingenuity began adjusting its velocity and tilting back and forth in an oscillating pattern. This behavior persisted throughout the rest of the flight. Prior to landing safely, onboard sensors indicated the rotorcraft encountered roll and pitch excursions of more than 20 degrees, large control inputs, and spikes in power consumption. The resulting inconsistencies significantly degraded the information used to fly the helicopter, leading to estimates being constantly "corrected" to account for phantom errors. Large oscillations ensued.

Dark Matter findings suggest Einstein’s Theory of Relativity “may be wrong”


BBC News shows that "Dark Matter" is perhaps the most mysterious substance in the universe.  

Little is known about it.  Scientists are pretty sure it exists but don't know exactly what it is.

Yet it is fundamental to their explanation of the Universe. They believe it permeates space and amounts to around 80% of all matter. 

Dark matter does not emit or absorb light but is subject to the effects of gravity.  Because of that, astronomers can measure the way it distorts light from distant stars. 

Now for the first time they have mapped the distribution of dark matter in the Universe.  However the findings have deepened the mystery because they seem to contradict Einstein’s Theory of Relativity, one of the central pillars of modern physics. 

Sophie Raworth presents BBC News at Ten reporting by science correspondent Pallab Ghosh.

A huge part of the matter in the universe really is: dark matter. You can't really so-called "see" it. But, you could see the effects of its gravity. Experts are thinking about how this matter can really behave.

Scientists can see how dark matter is distributed based on how its gravity affects light. However, when astronomers compared recent data from the Hubble Space Telescope and the Very Large Telescope to current models, something didn’t really add up.

So-called "Current assumptions" about dark matter physics might not be entirely correct.

Dark matter is a form of matter thought to account for approximately 85% of the matter in the universe and about a quarter of its total mass - energy density or about 2.241×10⁻²⁷ kg/m³.

Dark matter can refer to any certain substance which interacts predominantly via gravity with visible matter (e.g., stars and planets). Hence in principle it need not be composed of a new type of fundamental particle but could, at least in part, be made up of standard baryonic matter, such as protons or neutrons.

Here is the explanation of "dark matter" in really simple terms. Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. We seem to know that dark matter exists because of the effect it has on objects that we can observe directly.

Proving that dark matter exists is certainly a difficult task. Scientists have not yet observed dark matter directly. It doesn't interact with baryonic matter and it's completely invisible to light and other forms of electromagnetic radiation, making dark matter impossible to detect with current instruments.

Some people may wrongfully think that there is no dark matter. However, without dark matter, galaxies would lose a large fraction of the gas that forms new stars immediate after the first major star-forming event they experienced.

Dark matter theory is certainly needed to account for the fact that galaxies don't seem to obey the fundamental laws of physics. That led scientists to believe there must be some invisible matter there to create a stronger gravitational pull and really faster stellar motion.

China reports rover's first drive on Mars


China certainly said that the Martian rover took a first drive on surface of Red Planet. A remote-controlled Chinese motorized rover drove down the ramp of its landing capsule on Saturday and onto the surface of planet Mars, making China the first nation to orbit, land and deploy a land vehicle on its inaugural mission to the Red Planet.

Planet Mars is certainly the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet."

How SpaceX Build Their Rockets So Fast?


Futurity Channel on Youtube shows that SpaceX handles two-thirds of NASA’s launches (including many research payloads). It is interesting how Elon Musk manages to get his SpaceX employees to build successful rockets so quickly.

Since June 2010, rockets from the Falcon 9 group have launched 114 times, with 112 successful launches.

It seems that SpaceX is currently the only privately owned company that successfully delivers humans to the international space station.

It seems that the SpaceX flights are as cheap as $62 million, roughly two-thirds the price of a rocket from United Launch Alliance, a competitor.

How exactly does SpaceX manage to build their rockets so fast? 

It sure takes exceptional engineering.

Their rockets are all made with innovative technology. Some cost-saving options have been chosen, such as stainless steel (which costs about $3 per kilogram). Take a look at the full video for more explanations.

What If You Ate an Alien?


This alien video is pretty interesting. "What If" Channel on Youtube asks: Are we alone in this universe? Is there intelligent life out there? Or are they living among us? Humans have wondered about aliens for centuries. But, have you ever thought about the most important question of them all? Do you think this little green man tastes like chicken? Uh, I don't know if aliens will want to make contact after seeing this video. You've embarked on a galactic journey in search of extraterrestrial life. In the future, technology has advanced, allowing us to travel thousands of light-years away. We can finally explore the faraway planets in our galaxy. As you reach the first planet, your stomach rumbles in pain. You've been without food for days. The planet is barren and arid. There isn't anything around to eat. Except for this guy, an alien greeting you at the entrance of your spaceship. Houston, we have a problem, and you're going to kick our butts for this one. Why would you want to eat an alien in the first place? Would it be unethical? And, would they be safe to eat?

China spacecraft makes successful landing on Mars


DW News shows that China has landed a spacecraft on Mars. This is the latest step in its ambitious space program. The Chinese rover will stay in its lander for a few days of tests before  exploring the Red Planet. The rover has yet to send back any images from Mars, but here's the story of how it got there - and what the mission aims to find out.

The name Tianwen means "Heavenly Questions" or "questions to heaven" or "quest for heavenly truth", and comes from the long poem of the same name written by Qu Yuan (c. 340-278 BC), a poet of ancient China.

Tianwen-1 (TW-1; simplified Chinese: 天问; traditional Chinese: 天問 ) is certainly an interplanetary mission by the China National Space Administration (CNSA) to send a robotic spacecraft to Mars, consisting of an orbiter, deployable camera, lander and the Zhurong rover. The spacecraft, with a total mass of nearly 5 tons, is one of the heaviest probes launched to Mars and carries 13 scientific instruments.

The scientific objectives of the mission relate to the geology of Mars, the current and past presence of water, the internal structure of the planet, identification of minerals and rock types on the surface, as well as characterization of the space environment and atmosphere of Mars.

At 23:18 UTC, on 14 May 2021, the Tianwen-1 lander successfully landed in the preselected landing area in the southern part of the Mars Utopia Planitia. The planet landing phase began with the release of the protective capsule containing the lander/rover. The capsule made an atmospheric entry followed by a descent phase under parachute, after which the lander used retro-propulsion to soft-land on Mars.

The lander had a "treacherous journey" through the Martian atmosphere.

This is certainly a major triumph for China's space ambitions, and the culmination of years of hard work.

This is a key event for the China Aerospace and Technology Corporation.

This is the China's first rover landing on another planet.

The icy area of Mars known as "Utopia Planitia" was formed by the violent impact of an asteroid about 4 billion years ago. Past space probes have discovered large amounts of frozen water under the surface here.

Record breaking space jump - free fall faster than speed of sound


Watch the record breaking space jump from 24.2 miles (38.9 km) above the surface of earth by 'Felix Baumgartner'.

The video features the recording from the on-board camera, giving a true and absolute experience of the jump.

It also features a free fall which breaks the sound barrier (speed of sound) at 846 miles/hr or 1361.5 km/hr without the use of any heavy machinery.

China: New Space Station


The Tiangong Space Station (Chinese: 天宫 'Heavenly Palace') or Chinese large modular space station is a space station placed in low Earth orbit between 340-450 km above the surface. The Tiangong Space Station will be roughly one-fifth the mass of the International Space Station and about the size of the decommissioned Russian Mir space station. The Tiangong is expected to have a mass between 80 and 100 t (180,000 and 220,000 lb). Operations will be controlled from the Beijing Aerospace Command and Control Center in China. The core module, the Tianhe ("Harmony of the Heavens"), launched on 29 April 2021.

The construction of the station will manifest the 3rd phase of the Tiangong program. It builds on the experience gained from its precursors, Tiangong-1 and Tiangong-2. Chinese leaders hope that research conducted on the station will improve researchers' ability to conduct science experiments in space, beyond the duration offered by China's existing space laboratories.

The Chinese large modular space station is designed to be used for 10 years which could be extended to 15 years and will accommodate 3 astronauts.

With the core module deployed and stocked, China will launch 3 taikonauts to live on the CSS. The launch is expected to take place in June 2021. This crewed mission, named Shenzhou-12, will be China's 7th, and the first since the Shenzhou-11 mission in 2016.

China is seeking to enhance its capacity for scientific and technological innovation by building the large modular space station.

UFO flying close to SpaceX capsule


A weird mysterious object was certainly captured on video soaring close to the SpaceX Crew Dragon shortly after the astronauts left earth Friday morning. Sources say it could be ice from liquid oxygen in the rocket.

The so-called Dragon spacecraft is capable of carrying up to 7 passengers to and from Earth orbit, and beyond. It is the only spacecraft currently flying that is capable of returning significant amounts of cargo to Earth, and is the first private spacecraft to take humans to the space station.
