A new thread for a miniature (cubesat) moon lander. OMOTENASHI (a convoluted acronym which is also a Japanese word for 'selfless hospitality) is one of ten cubesats to be launched with Artemis 1, possibly as early as Monday, 29 August 2022 (two days away as i write rhis).
The lander has received little attention because it is really just a technology demonstrator of a method for getting very small objects safely to he lunar surface. Basically, let it come zooming in at 2 km/sec, slam the brakes on with a retro firing just above the surface and then let it fall to a hard but survivable landing. It's not totally dissimilar to the Soviet Union's Luna 9. Luna 13 landing method. Originally it included an airbag but that will not be used now. This landing demo does no science on the surface, though part of it will will collect some radiation data during approach. The only sign of a successful landing will be radio transmissions for a brief period. LRO may see evidence of the impact of the cruise module (which is not braked), though it will be small. The landing target is on the nearside limb south of Orientale at roughly 45 south, 75 west (285 east). Phil -------------------- ... because the Solar System ain't gonna map itself.

OMOTENASHI is in space... that's the good news part of this. The bad part is that it is not doing well, tumbling and not communicating, with limited time to correct the problem.
Some other cubesats flown with Artemis 1 are OK, some are not, and they do not correlate with whether or not they were recharged before launch. As I said earlier, Artemis may be outside our area of coverage for UMSF, but the lunar cubesats are presumably OK and we may get some interesting things - impact flashes on the lunar farside from EQUULEUS, infrared observations during a low flyby from LunIR, ice mapping from LunaH-Map, possibly some lunar images from ArgoMoon.
