What? No talk about the Mars Rover?

I wonder if the Discovery Channel will do somthing on this? It seems like a prime oppurtunity for a good hour long feature or documentary.

I think it was mentioned that the rovers' missions will Last about 3 months. That gives lots of time to explore once they start roving.

The problem with the previous "Pathfinder" mission was that the NASA guys said there wasn't enough "science" on/from it. The new rovers as mentioned already are much larger and packed with lots of excellent instruments!

Let's just hope the other rover lands safely too!

I wish we had a camera crew there to watch the landing in real time not computer generated. I could see some alien on Mars looking into the sky thinking WTH? That is one HUGE piece of hail. Oh well I digress.

I was thinking, if they had a permanent satalite in orbit around mars, the future landers could save on payload by using it as a relay to send info back to earth. That way they wouldn't need such big bulky transmitters. The space could be used for more scientific equipment.

Just a thought, Cheers!

If sucessful, does anyone know how far apart they will be? Or how fast and far they can go?
Would be way cool to see them taking pictures of each other!

I was thinking it's a shame that one of them isn't close enough to the Beagle 2 to roll over and give it a kick and see if that doesn't get that one working.

They're two satellites in permanent orbit of mars, they are the Global Surveyor and a weather satellite.

There are several permanent orbitting sattelites areound Mars. I am not sure but I suspect they can relay Messages in a pinch. To do that for all the communications isn't that efficent I don't think though. It's easier for the rover to track in on the Earth far away then to track a sattelite whipping about in a close mars orbit. Especially since the orbiters useally go into a polar orbit to make coverage of the entire planet easier. Your windows of communication would be much smaller than with direct comm back to earth. The limiting factor in bandwith isn't the transmitting power as much as it is the line of sight window. Unless you put the mars orbitter in a geo-synch orbit, and then it's not much good for anything but relaying Messages, which is an aweful waste of resources.

With a big enough antenna on Earth you could probably pick up a transmitter on mars not much bigger then a cell phone.

I'm not a sattelite communications expert, but I play one on tv...
