TL;DR: The in situ spectral reflectance and elemental analysis of the lunar soil at the landing site suggest that the young basalt could be derived from an ilmenite-rich mantle reservoir and then assimilated by 10–20% of the last residual melt of the Moon's magma ocean.

TL;DR: In this article, the first parallax and proper motion measurements of 6.7 GHz methanol maser emission using the Australian Long Baseline Array were conducted, and it was shown from the Lyman continuum photon flux that the embedded core of the young star is of spectral type B1.
