With the Shuttle put to bed, and now Constellation, NASA is done.
NASA is by no means done nor are they sending up just a few probes. In addition to MSL, there are several missions getting ready to launch over the next few years to Jupiter and other bodies. We are sending up a number of Earth science satellites to get the data to prove or disprove the claims of global warming and to find out new information about our planet. In addition there are missions that are in development to get samples from the moon and to go to Venus. Finally, some of our probes are still traveling to their targets deep in space. As for Constellation, I for one think this will be a boon for NASA. Constellation and its dream of easy manned space flight in our time was a waste of money and resources. We want a real mission, lets go to MARS! Forget the moon. If anything Constellation was an exercise in engineering not science and exploration. This decision does not set us back but frees up money for NASA to do some real science. Lets face it, a rad-hardened, thermally tolerant robot that can take huge accelerations and feed on sunlight is way better than a sack of meat. PS I work for JPL so I kinda have a stake in this.
