> "Touchdown confirmed. We're safe on Mars!" a mission controller announced. The cheers were deafening. I didn't cheer until I heard that they had telemetry from the surface. Then I cheered. Rover health on the surface seems good so far as I can tell. It looks like a landing on flat terrain. Fore and aft cameras are both working and sending back images. The temperatures of the two RTGs seem to be OK. I found out a bit more about the rover today. It has a laser ray-gun that can zap rocks with enough power to vaporise them.
