Rocket booster won't hit the kingdom: Gistda

https://www.bangkokpost.com/thailand/ge ... dom-gistda

The Space Technology Research Center under Gistda previously said the chance of the debris hitting Thailand was 1.2% but in an updated forecast in afternoon said the rocket will not pass Thailand.

"Thailand will not bear any impact. Do not panic," it said.

The booster weighs about 21 tonnes and it is expected to break up as it enters Earth's atmosphere.

The debris may weigh less by the time it hits the Indian Ocean, though it will still be going at speed.

Gistda has the technology to predict when space debris will fall up to a day in advance, it said.

Previously, the centre said the rocket booster would enter orbit over Thailand twice yesterday and today, but the latest information shows its trajectory will not pass the country.

Some netizens on social media were worried about a close shave.

China launched its Long March-5B mission on July 24 to connect its Wentian module with the Tianhe space station for research.

Gistda has developed its Space Traffic Management System to analyse data and predict incidents on Earth and in the oceans, including the booster's fall.

Gistda says it will add more functions to the system from available space data.

Not surprised really, as they have made several different predictions!

Space junk potentially found in NSW Snowy Mountains paddocks

https://www.abc.net.au/news/2022-07-29/ ... /101277542
SpaceX rocket debris lands in sheep paddock, Australian Space Agency confirms

https://www.abc.net.au/news/2022-08-03/ ... /101295488

The Australian Space Agency has confirmed debris found in the NSW Snowy Mountains belongs to SpaceX.

Three pieces of space junk have so far been found in the region, which are considered to be the biggest pieces found in Australia since 1979.

Two pieces were inspected by technical experts from the Australian Space Agency and NSW Police on Saturday.

Police have since confirmed they were also aware of the third piece being found in the region.

Authorities believed the space debris belonged to SpaceX but had been awaiting confirmation.

"The agency has confirmed the debris is from a SpaceX mission and continues to engage with our counterparts in the US, as well as other parts of the Commonwealth and local authorities as appropriate," an Australian Space Agency spokesperson said.

"The agency is operating under the Australian Government Space Re-entry Debris Plan which outlines roles and responsibilities for key Australian government agencies and committees in supporting the response to space re-entry debris."

It comes after locals reported hearing a loud boom on July 9, which was considered to have been caused by the SpaceX Dragon spacecraft, which was launched in November 2020, re-entering Earth's atmosphere.

Locals in the regions are being told that there's a possibility more pieces could still be found.

"If the community spots any further suspected debris they should not attempt to handle it or retrieve it," the agency said.

"They should contact the SpaceX Debris Hotline at 1-866-623-0234 or at recovery@spacex.com."

So what happens now?

While the space debris is expected to remain at the properties where they were found for now, the pieces could eventually be returned to US soil.

Australian National University's Institute of Space deputy director Cassandra Steer said there was an obligation under international space law to repatriate any debris to the country from where it originated.

"Any space object, or part thereof, has to be repatriated, and I'm sure that's what's going to happen in this case as well," she said.

"Unless SpaceX says that it wants no part in the costs associated with it, and it would like to donate the debris to science, that's quite possible.

"But it should be sent back to the US."

Dr Steer said it was significant that there was confirmation the debris belonged to SpaceX.

"We have clarity in terms of lines of responsibilities," she said.

"The US is liable for any damage that is caused by this space debris ... and Australia could go to the US and seek some form of compensation if there are any costs involved in cleaning it up."

But she was confident the situation would be resolved amicably.

"Clearly this is not going to turn into a horrible diplomatic event; the US is one of our closest allies and partners," she said.

"But there does need to be a government-to-government response in to how to deal with this.

"Thankfully in this situation it doesn't look like there's huge, enormous damage so hopefully it can be sorted out very amicably and without any international diplomatic incident."

SpaceX has been contacted for comment.

James Webb Space Telescope images reveal stunning galaxies, complex adolescent cosmos

https://www.abc.net.au/news/science/202 ... /101322658

The adolescent phase of the universe was much more complex than imagined, detailed snapshots of the early cosmos from the James Webb Space Telescope (JWST) reveal.

"There are many more galaxies with obvious disks, bulges, spiral arms … appearing earlier in cosmic time than we thought," Karl Glazebrook says.

^ Incredible images!

Always blows my mind this stuff being a reminder of just how tiny we are. We're tiny even in our own galaxy yet there's an estimated 170 billion other galaxies out there (or two trillion according to a theoretical calculation from a few years ago accounting for galaxies 'too small, faint or distant to be seen'!). Our little home is a mere speck of dust.

Always been fascinated with the Voyager Programme - absolutely incredible

Voyager 2: An iconic Spacecraft That's Still Exploring 45 Years On

The interstellar vagabond continues to explore the cosmos along with its twin, Voyager 1.

"Voyager 2, was the first of two twin probes NASA sent to investigate the outer planets of our solar system.

The probe was launched aboard a Titan IIIE-Centaur from Cape Canaveral Space Launch Complex 41 (previously Launch Complex 41) on Aug. 20, 1977, its twin spacecraft Voyager 1 was launched about two weeks later on Sept. 5. NASA planned for the Voyager spacecraft to take advantage of an alignment of the outer planets that takes place only every 176 years. The alignment would allow both probes to swing from one planet to the next, with a gravity boost to help them along the way.

While Voyager 1 focused on Jupiter and Saturn, Voyager 2 visited both those planets and also ventured to Uranus and Neptune. Voyager 2's mission to those last two planets would be humanity's only visit in the 20th century.

Voyager 2 is now traveling through interstellar space. As of early November 2018, NASA announced that Voyager 2 had crossed the outer edge of our solar system (Voyager 1 crossed the boundary into interstellar space in 2012.) Voyager 2 is now approximately 12 billion miles (19 billion kilometers) away from Earth and counting!"

Well, I for one will be watching.... Though I will avoid the rendition of the "Star Spangled Banner" and "America is Great" - no offence intended, proud they should be...... It's just always a little over the top.

NASA's Epic Artemis 1 Moon Mission Launch is Just 1 Week Away

"Artemis 1 is scheduled to launch on its journey to the moon on Aug. 29.

NASA's historic Artemis 1 mission will launch toward the moon one week from today (Aug. 22), if all goes according to plan.

Artemis 1, the first mission in NASA's Artemis program of lunar exploration, is scheduled to lift off from Florida's Kennedy Space Center on Aug. 29 at 8:33 a.m. EDT (1233 GMT). You can watch it live here at Space.com when the time comes, courtesy of NASA."

A long article with inside facts and explanations:
..............................................................................................
Artemis 1, NASA's first mission to the Moon since Apollo, set to take off tonight

https://www.abc.net.au/news/science/202 ... /101347494

NASA's long-awaited return to the Moon is set to come one step closer with tonight's launch of the biggest and most powerful rocket ever built.

The rocket is planned to blast off from the Kennedy Space Center at 10.30pm (AEST) from the same pad used by the last Apollo mission 50 years ago.

Perched on top of the 32-storey-high rocket is a new space capsule set to fly beyond the Moon and back again.

"We will launch the world's only spacecraft designed to carry humans into deep space, atop the most powerful rocket,” NASA chief Bill Nelson said.

Captained by a crash-test dummy called Commander Moonikin Campos, (no, not the F1 driver :wink: ), the uncrewed flight is the inaugural test run for the Artemis program, NASA's push to put humans back on the Moon and eventually travel to Mars.

"With the Artemis 1 launch, NASA … is poised to begin the most significant series of human exploration missions in over a generation," said Bhavya Lal, NASA associate administrator for technology, policy, and strategy.

The 42-day journey will not only push the brand new rocket and capsule to the limit, it will test a new orbit, and go further than a craft capable of taking a crew further beyond the Moon has ever been before.

It will also release 10 shoe-box-sized satellites to scout the Moon and explore conditions for future deep-space missions.

A big test for new spacecraft

Even though the rocket and the capsule might look a bit retro, the mission is very different to the Apollo missions that ran on less computer power than your mobile phone today.

Well another launch bites the dust. Don't think I'd like to sit atop of this thing!! :roll:

"The US space agency has had to postpone the launch of its new Artemis I Moon rocket for the second time in a week.

Controllers were unable to stop a hydrogen leak on the vehicle, almost from the start of Saturday's countdown procedure.

Nasa now has another opportunity to launch the rocket on Monday or Tuesday.

After that the vehicle will have to return to its assembly building for inspection and maintenance, which will mean further delays."
