QUESTION: What's it feel like to be involved with something so important and big? Is it exciting? Do you get stressed out over all of it? ANSWER from Donna Shirley on December 29, 1997: Yes, of course it's exciting. And of course we were all very nervous for the Pathfinder landing and the Mars Global Surveyor entry into Mars orbit. All of us have worked for many years to get to Mars and it really is neat to be there.
