SLS finally launches to the Moon. SpaceX gets another contract from NASA. James Webb gets a protection plan from micrometeoroids. A Chinese booster shreds in low-Earth orbit. A secret space plane returns.

NASA’s rolling geology robot shared a great image of sandstone that it found on Mars in Jezero Crater. It’s in a region called “Yori Pass”, which is part of an ancient river delta. Perseverance will take rock samples there for the upcoming Sample Return Mission. They should tell more about what happened with water in this region. And maybe they’ll show evidence of life.

There’s a growing body of evidence that galaxies grow large by merging with other galaxies. Telescopes like the Hubble have captured dozens of interacting galaxies, including well-known ones like Arp 248. The Andromeda galaxy is the nearest large galaxy to the Milky Way, and a new study shows that our neighbour has consumed other galaxies in two distinct epochs.

After months of waiting, we’re getting our first good looks at a fully deployed BlueWalker-3.
A new high-profile satellite may now be visible in a sky over you. We recently wrote about AST Space Mobile’s new BlueWalker-3 satellite, and its potential to be among the brightest objects in the night sky. Launched on September 10th, 2022 an a SpaceX Falcon-9 rocket along with the Starlink Group 4-2 batch, BlueWalker-3 is the first of the company’s planned mega-constellation of 110 BlueBird satellites set to be deployed by the end of 2024 for worldwide communication.

As we’ve reported here more than a few times – space debris is becoming more and more of a real problem. We’re not quite at Kessler syndrome levels yet, but with the increased interest in getting things into space, there is a real possibility that might happen in the not-too-distant future. Plenty of potential solutions have been put forward to deal with the problem, but they all face a similar problem at the first step – how to track the debris they’re attempting to eliminate. Enter a new idea from researchers in Iran – using a novel type of radar to detect and track space debris before it becomes a danger.

Japan and Germany have a history of collaboration in scientific and technological endeavours. The countries have a Joint Committee on Cooperation in Science Technology that has met many times over the decades. Both countries have advanced, powerful economies and sophisticated technological know-how, so it makes sense they’d collaborate on scientific activities.
This time, their cooperation concerns a small, potato-shaped chunk of rock: Mars’ moon Phobos.

What’s the most exciting thing about the James Webb Space Telescope? The stunning images? The completion of its torturous path from concept to launch?
Or is it because it provides such compelling visual evidence of objects and processes long theorized about but difficult to observe?

Micrometeoroid strikes are an unavoidable part of operating a spacecraft. But after the James Webb Space Telescope (JWST) was hit with a larger than expected piece of space dust earlier this year, engineers are making changes to the way the telescope will be pointed in an attempt to avoid excess or larger impacts from space dust.

The November Leonid meteors may produce a surprise outburst this weekend.
If forecasters are right, a notorious meteor shower may put on a surprise showing soon, right after its expected peak. The meteor shower in question is the November Leonids. Most years, the Leonids are really nothing to wake up early for, producing an average hourly rate of 10 meteors an hour, barely double the background sporadic rate. But every 33 years or so, the Leonids are the source of great storms of meteors, as the Earth plows headlong into the stream of debris laid down by comet 55P/Tempel-Tuttle on its 33-year orbit around the Sun.

GPS and the world’s other global positioning systems all have one very limiting disadvantage: they’re global to only one world. There is no equivalent to the precise geolocation features these systems offer for any other body in our solar system. Recently, there has been an increased focus on Lunar missions, but no way for anything on the Lunar surface to know precisely where it is. Enter the European Space Agency and their Moonlight initiative, which was showcased in a recent video on their YouTube channel.
