Chandrayaan-3: The 1992 Conference on Lunar and Planetary Instability, Volatility and the Regolith Composition

Snyder, G. A., Taylor, L. A., Liu, Y. G. & Schmitt, R. A. in Proc. 22nd The lunar and planetary institute had a conference in 1992.

Chandrayaan-3’s Vikram lander touched down on 23 August 2023. It released a rover called Pragyan, which collected data ranging from temperature to seismological measurements over 10 days.

Pragyan also studied the chemical composition of the regolith: the fine material that covers much of the lunar surface. The rover stopped 23 times and deployed an instrument called an alpha-particle X-ray spectrometer (APXS).

“It’s sort of what we expected to be there based on orbital data, but the ground truth is always really good to get,” says Lindy Elkins-Tanton, a planetary scientist at Arizona State University in Tempe.

Anisotropy of the lunar basins revealed by Clementine laser ottimetry: Implications for Moon formation and the origin of the Moon

The best model for the origin of the Moon is that the newly formed Earth was struck by a large impactor called Theia, which blasted a large amount of material into the air. The moon was formed quickly by the scattered material. This impact theory explains why lunar rocks have an isotope composition similar to those on Earth.

Vadawale and his colleagues found that their samples contained elevated levels of magnesium compared with those of calcium. This suggests that deeper mafic material has been mixed into the regolith.

But one problem with that idea is that the South Pole–Aitken basin seems to be dominated by a mineral called pyroxene, which doesn’t quite fit Pragyan’s data, says Anand. Resolving this will probably require samples to be brought back to Earth, he says.
