Lander-cam
>>>...Mars Pathfinder, which landed at Ares Valles at 3 a.m. local time, when wind shear was predicted to be low or non-existent, still managed to bounce nearly 2 km from the initial impact point.
This suggests an addition to an airbaglander: add 4 fortified video spy-cams to the outside of the airbags. Record the entire spectacle of the landing and send it back later. Discard the cams with the airbag.
Not sure how much scientific use the videos would be, but it would be fun to watch in slo-mo! It would give a good reconnaissance of the landing area (certainly along the bounce-path). Should give some interesting shots of the soil before and after being slammed by an Earthly "bat-out-of-hell".
