Mr. Vice President, there will be nothing bigger in this century than the first human landing on Mars and the establishment of a permanent base on the Moon. And you can make it happen.  A bold, vibrant space program will relaunch America's leadership in high technology and save and create a great many jobs.

Please act now to save the Space Shuttles, build Constellation, and honor JFK's legacy with a bold space program to go to the Moon, Mars and asteroids. Not decades from now, but within 10-15 years.

That's "something big!"
