Why Did NASA Just Launch a Planetary Defense Mission?

"Unveiled" Channel on YouTube shows what it is that NASA is worried about. Earth really needs defending.

The so-called Double Asteroid Redirection Test (DART) is interesting. Launched in November, 2021, this is one of NASA’s most ambitious planetary defense projects to date. The SpaceX head, Elon Musk, even says it could "avenge the dinosaurs"! This informative great video takes a closer look.

The fascinating Double Asteroid Redirection Test (DART) is a NASA great space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). In September 2022, a certain space probe is set to deliberately crash into the minor-planet moon Dimorphos of the double asteroid Didymos to assess the future potential of a spacecraft impact to deflect an asteroid on a collision course with Earth through a transference of momentum.

DART is a joint project between NASA and the Johns Hopkins Applied Physics Laboratory (APL). It is being administered by NASA's Planetary Defense Coordination Office, and several NASA laboratories and certain offices are providing technical support. International partners, such as the great space agencies of European Space Agency (ESA), Italian Space Agency (ASI), and JAXA Japan, are contributing to related or subsequent certain projects. In August 2018, NASA approved the important project to start the final design and important assembly phase. The interesting DART spacecraft was successfully launched on 24 November 2021, with collision slated for 26 September 2022 to 2 October 2022. Check the news after the collision to see the results.

The First Thing That James Webb Will See

The Secrets of the Universe on YouTube shows that the great powerful James Webb Space Telescope launched on 25 December 2021. As the whole world awaits the first exciting images from the iconic space amazing big telescope, here is what the first year of observation will look like. It will still take up to 3 months for the telescope to return its first image. However, once it is fully successfully deployed, the James Webb Space Telescope will certainly be the most powerful fantastic telescope at work in outer space.

Revolutionary James Webb telescope blasts off into space

DW News shows that a great revolutionary telescope has been launched into space, marking the beginning of a new era of scientific exploration.

The James Webb great telescope - named after a former head of NASA - lifted off on board a rocket from the European Space Agency's launch base in French Guiana. The launch is the culmination of several tough decades of work by European, Canadian and USA space agencies. Many call this the world's most powerful telescope.

It is nice to know that the great launch went well (the thing did not explode or anything bad like that).

The great $9bn observatory will seek out light from far away stars and galaxies, providing a glimpse into cosmic creation.

The fascinating $9bn observatory hurtled towards its destination 1.6 million km (1 million miles) away - or more than 4 times beyond the moon.

NASA’s James Webb Space great Telescope certainly soared up from French Guiana on South America’s northeastern coast, riding a European Ariane rocket into the morning sky on Saturday.

The next step is for the telescope’s large mirror and sunshield need to unfurl. They were folded origami-style to fit into the rocket’s nose cone. A risk is taken with this mission - hopefully there will not be many errors.

Scientists are certainly going to be able to examine the atmospheres of various planets and determine whether or not planets could be habitable and suitable for humans to possibly one day colonise. It is also interesting if "any lifeform" could exist on a planet.

This is a successor to the ageing Hubble Space Telescope. The long-delayed James Webb is named after NASA’s administrator during the 1960s. NASA certainly partnered with the European and Canadian space agencies to build and launch the new 7-tonne telescope, with thousands of people from 29 countries successfully working on it since the 1990s.

All around the whole world, various expert astronomers certainly had eagerly waited to see Webb finally taking flight after years of setbacks. It seems that last-minute technical snags bumped the launch nearly a week, then gusty wind pushed it to Christmas. Transporting the thing means it is shaking, so it has to be checked for perfection. It is also shaking during the space flight, and then later the mirrors and parts have to be perfectly aligned.

It is certainly a launch for humanity.

It seems that the launch was a a beautiful launch and everything went off without a hitch.

The telescope’s main showpiece is a gold-plated mirror more than 6.5 metres (21 feet) across.

Protecting the observatory is a wispy, 5-layered sunshield, vital for keeping the light-gathering mirror and heat-sensing infrared detectors at cold subzero temperatures. At 21 by 14 metres (70 by 46 feet), it is the size of a tennis court.

The plan is for the sunshield to be certainly opened 3 days after liftoff, taking at least 5 days to unfold and lock into place. Next, the mirror segments should open up like the leaves of a drop-leaf table, 12 days or so into the fascinating space flight.

For the entire mission, hundreds of complicated release mechanisms need to work perfectly in order for the telescope to succeed. This is really like nothing NASA has ever done before.

Interesting Coronavirus Art Images

Dec 23, 2021 - The latest genius science is studying the dangerous so-called Omicron Coronavirus Variant. Two new British studies provide some certain early hints that the Omicron virus variant of the coronavirus may be milder than the Delta version.

Findings of these early studies still have to be reviewed and certainly really proven. Maybe there is less severity, but Omicron spreads much faster than Delta and is more able to evade useful vaccines. Greater big numbers of dangerous infections could overwhelm hospitals in the near future.

Certainly people are likely to have some important level of immunity at this stage of the pandemic, either through vaccination or a certain previous COVID-19 infection. Be careful and good luck staying safe.
