The DAWN mission got inspired me to think about landing probes on low gravity(but not microgravity) bodies like Ceres which I guess is about 1/30g . Being too lazy to do the physics, if you just dropped one in, could you just pretty much use shock absorbers to land (maybe with some bouncing)? How about just letting a probe imbed? I know we attempted some embedding probes on Mars which failed, but on much lower gravity would the forces be so tractable that relatively cheap impact probe could be devised?

Any insiders on the DAWN mission know why any landing probes were avoided (probably just cost and complexity)? It seems like probes for those kind of gravity bodies might be relative inexpensive, but what do I know.
