No one thought there could possibly be a conflict, since MRO was not going to arrive at Mars until more than three years after the MERs, and of course the MERs would have definitely ceased functioning by then... Now they have to plan use of the MER DTE system and MRO's data link more carefully than otherwise, because of this conflict that no one thought could ever have happened. MSL is launching in two years (at least supposedly), and while one might make the assumption that the MERs will definitely be dead by then, the time between now and MSL landing is less than the time between the MER landings and now. Do we know for certain that MSL is being designed such that there will be no conflicts of any kind with the MERs, if either or both Spirit and Opportunity are still functioning when it arrives? There aren't any more spare S-band transmitters from the MER program that MSL is planning on using, are there...?

But, hey -- if they have all the cash they need, I should stop worrying and learn to love the Bomb... grin... -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Sure there are not many details known (yet) about the final design, but 2 1/2 years from launch small design changes are still likely. The instrument suite has been selected long ago, some small adjustments there are possible too. But the overall design is pretty much fixed. I would not worry about MSL, but about the whole NASA planetary program after 2010. Analyst
