No, it's time for the civilian sector to take over. For example, a Mars mission for purely exploration purposes should be run by by a private organization such as the National Geographic Society, probably in financial association with several universities and private donors.
Then we wouldn't have to listen to whiners who think "we should solve our problems on Earth before we spend money go to other planets." If it's private money rather than gov't money, they'll have nothing to whine about.
Do you know how much money it would cost to go to Mars? It would take billions
just to get the ship built, plus you have to use nuclear engines to propel it. Most universities are already coming under fire in the alternative press for doing research like this (due to the links that the military industrial complex has with the space program). What Americans need to do is start voting in a bloc to ensure funding of NASA, just like the religious right does. Then
a mission to Mars will happen, as well as a mission to the moon and other planets.
