We all know that MRO uses a backup S-band transmitter from the MER program, which operates on the same frequency as one of the MERs (Oppy, IIRC). 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...?
Just curious...
