they sent the entire flight program in advance, there's no direct remote control, once programmed it then flies to that program autonomously..... but it's just been destroyed by a death ray from a tripod.Obvious question, how did they overcome the time delay involved?
At a cost of around 80 million dollars it should be. I agree with you though, this is very clever stuff.
Mars is a challenge because of the thin atmosphere. I'm old enough to remember Viking 1 and 2. They were essentially sky-cranes with legs, sensors and nothing to lower. The airbag approach was clever but can't deliver a payload the mass of the last couple or rovers.I reckon that the most difficult bit was getting Perseverance to softly land on Mars, that's the part that always gets everyone nervous, the rest was relatively straight forward.
Nice to see it work anyway.
