A fun change to the regular work in the lab is the interaction with the public. Yesterday I visited the Astronomical Society of Hildesheim to talk about #Mercury and the #BepiColombo mission. 🛰️🚀🔭📡🧪

Molten #planets and early #atmospheres in the #lab: #mpsgoettingen scientist Christian Renggli receives one of this year’s ERC Starting Grants for his group ELMO (Experimental Laboratory Magma Ocean). Congratulations!!!

Christian Renggli receives an ERC Starting Grant.

In the Knudsen cell (the small white cylinder right next to the tweezers), only a few millimeters in size, an equilibrium is established between molten rock and evaporating gas. The gas is then analyzed in the quadrupole mass spectrometer.

In the furnace, artificial magma (here in the crucible[KDB1]) is produced from silicate rock and additives at temperatures of up to 1500 degrees Celsius.

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

On May 18, 1980, Richard Lasher got up early to get some photos at Spirit Lake. Instead, he was forced to stop because of the massive, explosive Mount St. Helens eruption and captured this iconic photo with his own red Ford Pinto on the road. 🧪⚒️ #OTD

Trump proposes unprecedented budget cuts for US science in next fiscal year
NASA cut by 24%
NIH cut by 40%
EPA cut by 55%
NSF cut by 56%

Trump proposes unprecedented budget cuts to US science

Huge reductions, if enacted, could have ‘catastrophic’ effects on US competitiveness and the scientific pipeline, critics say.

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

2) one molecule, if it can be produced by any abiotic process, will never be enough to definitively claim detection of life

"Days ago, the Administration’s nominee to lead NASA called for a “new golden age of science and discovery” at the agency. The proposed budget from within the White House — which cuts NASA science by 47% — would plunge NASA into a dark age instead."

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.

Massive cuts to NASA science proposed in early White House budget plan

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.

Michael Busch @michael-w-busch.bsky.social · Apr 8

Discussion of the lunar impact risk corridor for #2024YR4 in 2032: groups.io/g/mpml/topic... .

3 to 4% chance of lunar impact, with a few tenths of a percent on the far side and the rest on the near side.

But almost all on the day side.

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! 🚀🌕🔭📡🧪

European Space Agency @esa.int · Feb 21

☄️ 🔭 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%.
