To see the composition of #Mercury we first look at the #Moon SiO2 on the lunar surface and all the places from which we have samples. With data from @science.esa.int #BepiColombo we will get a detailed look at the composition of Mercury. For now, SiO2 may be super low, #Komatiite on the surface?

From glass beads and lunar map to #Mercury: New study indirectly determines SiO2-content of Mercury’s surface. With 37 %, it is less abundant than thought. Mercury’s crust must have formed by extreme volcanism. www.mps.mpg.de/mercury-s-cr... @uni-muenster.de @uni-goettingen.de @renggli.bsky.social

Three steps to Mercury. Step 1: Using laboratory measurements, the researchers established a relationship between infrared radiation and SiO2 content. Step 2: They verified this relationship using measurement data from the Moon and lunar samples. Step 3: Using infrared data from Mercury, the researchers were then able to determine the SiO2 content of Mercury’s surface.

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.

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. www.washingtonpost.com/science/2025...

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.

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! 🚀🌕🔭📡🧪

Because 2025 = 45² and 45 is a triangle number, we get these lovely sums: 2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)² 2025 = 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³ Pleasingly the next triangle number 55 is 10 more, so get ready for a repeat of this fact in the year 3025.
