A bit into the weeds, but: OSIRIS-REx and the Hayabusas had exposed sample return capsules. These capsules are necessary to get the sample back, through Earth’s atmosphere, via their heat shields. Can we count on their heat shields, even after space exposure (including micrometeoroid bombardment?) Huygens had multilayer insulation on its heat shield- should we do this more often?
Asteroid “landing” (more like docking) is easy… in the energetic sense. In the sense of flight dynamics, operations around small bodies are not earthlike in that gravity can be used as a reference and a stabilizing force. Buzz Aldrin wrote his thesis on the counterintuitivities of docking in space- not something one can just assume.
Speaking of not landing, the extended mission of Hayabusa2 includes a flyby of Torifune as a test of planetary defense- Haya2 will come close, but not impact. This is to demonstrate that JAXA could impact an asteroid, if they really wanted. Oh, and Haya2 will then ‘orbit’ (?) 1998 KY26, for both asteroidal and “comet” science.
Lastly, Ceres contains ice. Multiple bodies in the outer Main Belt are Main-Belt Comets, and contain ice. Multiple bodies exhibit nongravitational acceleration, and likely contain volatiles, likely of multiple sorts. Koßagk et al. prepare instruments for them.
