Forgive my simplistic question, but as the lander was designed to be unmanned and remote and allowing for various negative possibilities/scenarios that might occur, why was this scenario not considered and a planned strategy implemented ? Even now side mounted booster jets might have had a rescue possibility, though it would need some pretty good synchronisation to avoid toppling over in the opposing directions. As I understand things, the lander will have almost no relevant functional ability in regards to it's mission as things (don't) stand..
