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.

Tianzhou-2 - China’s first fast docking


SciNews Channel on Youtube shows that the members of the Tianzhou-2 mission describe the docking between the Tianzhou-2 cargo spacecraft and the Tianhe Core Module as "China’s first fast automatic rendezvous and docking." The Tianzhou-2 cargo spacecraft autonomously docked to the Tianhe Core Module on 29 May 2021, at 21:01 UTC (30 May, at 05:01 China Standard Time). Tianzhou-2 (天舟二号) is the first spacecraft to dock to the Tianhe Core Module (天和核心舱), the first and main component of the China Space Station (中国空间站).

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.
