Radio and video signals mars

  • #1
I was wondering what kind of things you would need to transmit to a satellite or something on mars and get video and whatever other signals back from there. Like transmit controls there for a rover to take and possibly to bring it back. So for the journey there and back.

A radio antenna, transmitter, and receiver. Due to the distance, the antennas should be parabolic dishes. The Mars rovers also use an orbiting satellite as a relay platform to reduce the power requirement of the landers.

You could probably find a lot of the info at NASA's website, under the pages on related projects. I'm sure the rover pages have lots of technical info, and pointers to more info.
