What? No talk about the Mars Rover?

[Cipher7071]

The new rovers are better because:

1. It has a much wider suspension for better stability.

2. The robotic arm carries a grinder that is able to take specimens, plus instruments to test them.

3. There is a much larger solar array to power the extra equipment.

4. The computer hardware and software are better.

There are probably other things that I have forgotten, or that weren't mentioned in the show. I guess I'll have to wait for some of the results to be published to learn the rest, unless anyone else knows...
