Giant asteroid could crash into moon in 2032, firing debris towards Earth
Researchers say satellites may be at risk and impact could create a spectacular meteor shower in the skies
If a giant asteroid smashes into the moon in 2032 it could send lunar debris hurtling towards Earth, researchers have said, posing a risk to satellites but also creating a rare and spectacularly vivid meteor shower visible in the skies.
Asteroid 2024 YR4 triggered a planetary defence response earlier this year after telescope observations revealed the “city killer” had a 3% chance of colliding with Earth. Continue reading...

NASA Goddard is pushing through a 48% staff reduction!!! This could impact the upcoming Roman Space Telescope and many other future Astro missions. News coverage seems not sensational enough. Are we really going to let NASA (as we know it) die quietly? www.space.com/space-explor...
NASA begins push to slash workforce with more staff buyouts, early retirements as budget cuts loom

Sarah’s rules of looking for life with only chemical signatures:
1) the smaller the molecule(s) the more likely they can also be produced by abiotic processes

First the rumour was a 20% budget cut. Then, 50%. Now the president's NASA budget is out and it's a 68% cut to astrophysics ($1.5B to $487M).
Even if this gets reversed in four years, we will *never* recover the missions, partners, people who will be gone.

The preliminary version of President Donald Trump’s budget proposal to Congress, known as a “passback,” would cut the agency’s science budget funding nearly in half.

Please hit the Moon 🌑💥 #2024YR4!
This would be very exciting from a science point of view 🧪🔭🛰️🚀⚒️
We could observe the impact plume from Earth, and perhaps also from orbit. If we manage to put a seismometer on the lunar surface we could learn a much about the Moon's interior.

OK, I'll be honest. I'm hoping for a hit on the Moon! With high certainty early on, so that we can put together an observation mission and perhaps even a few landed seismometers on the lunar surface. We would learn so much about the physics of crater formation, the lunar surface, and interior! 🚀🌕🔭📡🧪
☄️ 🔭 The impact probability of asteroid 2024 YR4 has dropped from 2.8% to 0.16%.
Thanks to new observations, Earth is now at the edge of our shrinking ‘uncertainty window.’
If this trend continues, the risk may soon reach 0%.
