Researchers want a vehicle that can cover ground quickly but also move slowly to examine an area. They want a vehicle that can "see" large areas from a height, but get down to the ground when they find something interesting. A rover can't do this because it can't fly. A normal airplane can't do this because it can't land just anywhere. But a helicopter can!
Despite Mars having a thin, cold, carbon-dioxide atmosphere operating a rotorcraft is entirely possible -- the low gravity helps somewhat, but the real secret is ultra-lightweight hardware components. Mars has a varied terrain, which makes surface vehicles difficult or impossible to operate. Rotorcraft could fly over the terrain low and slow enough to observe and film it.
I WONDER IF I CAN TRUST NASA WITH THIS INFO????? LO
Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
