Comet Probes Given New Duties

iamlucky13 writes "In January of 2004, the NASA's Stardust mission made a flyby of comet Wild-2, taking images and collecting samples from its tail that have since been returned to earth in a detachable capsule. On July 4, 2005, Deep Impact smashed a 350 kg projectile traveling 37,000 km/h into comet Tempel 1 as part of its studies of that object. With both craft in good shape at the end of their missions, NASA has been considering additional tasks for the probes. These plans have now been confirmed with a variety of tasks costing an estimated 15% what a new mission would. Among the new duties will be a revisit of Tempel 1, a flyby of comet Boethin, and transit studies of known extra-solar planets."

I think they are doing the right thing by keeping mission expectations low. Ambitious missions that fail to deliver are seen as failures by shortsighted lawmakers. Toned down missions that outperform look much better.

Most people only follow space exploration at the soundbite level (evening news or whatnot). Hearing that yet another vehicle continues to operate beyond its life expectancy is a good way to create a positive perception of NASA in the general public.

Same thing goes for just about anything. Don't promise what you can't provide. In my 4th year software engineering project class for university, some students took on monumental projects, and had to scale them back quite a bit to get something finished. The professor actually took this into consideration and many students lost marks because of it. However, the groups that were able to properly scope a project for the resources they had available were given better marks because it showed better planning ability. Vista is seen as a failure because of all the things it didn't provide (Monad shell, WinFS), and because it was way behind schedule. Even though it has some good features, it's seen as a failure because they promised so much that didn't show up in the end.
