The Chang'e 6 mission has unveiled that the Moon's far side mantle holds significantly less water than its near side, offering crucial insight into the Moon's geological history. Analysis of rock samples from the mission indicates water content in the far side's mantle is as low as 1 to 1.5 micrograms per gram-less than 2 parts per million-marking the driest values ever recorded in lunar geology

Astronomers at W. M. Keck Observatory on Maunakea, Hawai'i, have traced the origin of 2024 YR4, an Earth-crossing asteroid discovered in December 2024, to a surprising location. Contrary to expectations, the solid, stony asteroid appears to have emerged from a central Main Belt asteroid family between Mars and Jupiter-a region not previously associated with Earth-crossing bodies.

A steering command halted the drive a little short when we tried to turn-in-place but instead turned into a rock, which also had the effect of making our position too unstable for arm activities. Oh well! APXS data has been showing

Every galaxy is thought to form at the center of a dark matter halo - a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't yet know whether star-free dark matter halos exist.
