There are lots of great opportunities for you to be directly involved in space.
I have been meaning to post this for awhile, so sorry for the delay. If you act before June 27 you can send your name to the Moon. The Lunar Reconnaissance Orbiter team has thus collected over a million names so far. Make sure yours gets included.
Washington D.C. holds the Smithsonian Folklife Festival on the National Mall. Usually, they choose one Country, one City, and one cultural region. This year, instead of a cultural region, they chose to honor NASA. So if you happen to be in Washington D.C. between June 25-29 or July 2-6 you can help celebrate 50 years of space exploration in the U.S.A.
If you are really ambitious, the application deadline for the next NASA Astronaut Class is July 1. I am not applying at this time, but you can put your name in the mix here.
