Right. Getting to 0 mph is pretty much assured. The difficulty will be ensuring they don't get to 0 mph any quicker than seven minutes. Apollo 10 went from 24,790 mph (almost twice as fast) at entry interface to 125 mph at main chute deployment in just 11 minutes. Of course we do have a bit more atmosphere to help out.

A Space.com story has this comment about Curiosity: "the spacecraft must slow itself from roughly 13,200 mph (about 21,250 kilometers per hour) to zero in only seven minutes." Getting it to zero mph in seven minutes shouldn't be a problem even if everything fails ..... Joe
