Landing mechanism is cool too. The lander has deformable metallic sponge balls on the legs, hits the soil at its "heel" and tip forward[1].

Official reasons given is it allows reduction of structural margins, physical interferences and tipover risks on inclined surfaces, which seem to make sense. Maybe it's just me that it looks a bit like someone had to have a spacecraft that lands like the Space Shuttle with engines pointing back.
