Mars is littered with failed spacecraft.
At 4:20 he says, "20 meters about the surface we have to lower the rover on a tether that's 21 feet long." Ummm... remember the last time NASA mixed up metric and English units? That probe never slowed down and smashed into Mars. Suddenly, I'm very nervous for this mission. ("Why isn't the tether long enough? We made it 21 feet long and the skycrane is only 20 meters from the surface!")
A 30 old minute TV program would run about 25 new minutes, which in the new system is a quarter hour. One new hour would be 2:24 old hours, so a standard movie with commercials would have a run-time of about one new hour. Metric time was proposed when France was putting the metric system in place, but it was rejected because people did not want to give up their timepieces which were often the most valuable thing people owned. And how about a 13-month calendar while we're at it?
Still, well done NASA!
