Another one emerging from the vast Planetary Radio archives. Emily in her inpersonation of Sandy Moondust sitting on MER-B before launch (check the Astrobots project if unfamiliar with that biggrin.gif ) said that it was to be launched on a heavier vehicle than MER-A, namely Delta 2 heavy with strap-ons 6" thicker than a regular Delta 2. Why is that so? Why launch two identical rovers on two different rockets? And - was it also the case with the Viking and Voyager pairs?

OK, kewl. I know that Oppy got off literally at the very end of her launch window, as well, due to issues with (among other things) debonding of cork insulation around the booster. IIRC, Squyres made the comment at one point that no one ever proved that the cork actually stayed bonded to the vehicle during flight, and that they might have left a trail of cork pieces all along the Atlantic Missile Range...
