- Earth Microbes Could Persist in Lunar Shadows — Space.com
Laboratory tests show certain terrestrial organisms survive conditions that mimic permanently shadowed lunar craters. The study suggests microbes could endure in thin films of water ice protected from solar radiation. Researchers note that even small disturbances such as rover tracks might create temporary habitable pockets. Future missions will need to weigh contamination risks against scientific goals. Space.com quotes the finding that a bootprint or rover tread may create a habitable area. The work focuses on the lunar south pole environment.
- Deimos Shaped by Ancient Impact — Universe Today
New analysis indicates a single large collision excavated Deimos’s prominent south-polar crater and left a thick regolith blanket. The moon’s low density and porous interior suggest it behaves like a rubble pile rather than a solid body. The findings help explain why smaller craters appear buried across its surface. Similar processes may affect other small satellites throughout the solar system. Universe Today reports the impact model accounts for both the large crater and the widespread regolith layer. The moon’s fragile structure implies it could re-accrete after major collisions.

China’s Chang’e 7 mission will attempt the first landing near the lunar south pole with a full suite of surface vehicles. A stationary lander will anchor the mission while a rover traverses nearby terrain and a hopper leaps between shadowed craters. The spacecraft will also deploy instruments to measure water-ice signatures and local radiation levels. Success would give China operational experience at one of the most scientifically valuable sites on the Moon and set the stage for longer-duration surface operations. The mission architecture includes a dedicated relay satellite to maintain contact from orbit.
Deimos measures only about twelve kilometers across, yet one ancient collision appears to have reset much of its surface. Imagine a city-sized boulder striking a loosely bound rubble pile at several kilometers per second; the shock wave travels through the porous interior, lofting regolith that settles into a blanket thick enough to bury older craters. The same event excavates the prominent south-polar basin now visible from orbit. Because the moon’s bulk density sits well below that of solid rock, the impact energy dissipates quickly rather than shattering the body completely. Spacecraft imagery already maps the resulting crater and regolith distribution, but we still do not know how many such events a rubble-pile satellite can absorb before it disperses or re-accretes into a new shape. The low density also means the moon’s gravity is too weak to hold onto fine material ejected during later small impacts, leaving the surface in a state of slow, ongoing rearrangement.
New data on small-body collisions and lunar resource searches are sharpening our picture of how fragile worlds evolve and where future explorers might find water.
