Ever wonder what it’s like to be a real astronaut? What would it be like to feel the g-forces of spaceflight? How do you perform everyday tasks out in space? Well, here’s your chance to find out.

To celebrate the 40th anniversary of man’s first steps on the Moon, Astronomy magazine is teaming up with Borders and the Kennedy Space Center Visitor Complex to bring astronomy enthusiasts the “Train Like an Astronaut” Sweepstakes. Now through July 27, you can find a form at Astronomy.com to enter for a chance to win a 4-day trip to the Kennedy Space Center Visitor Complex outside Orlando, Florida. Three Grand Prize winners will each receive roundtrip airfare for the winner and three guests, three-night accommodations in Cocoa Beach, car rental for four days, and the chance to participate in the Family Astronaut Training Experience at Kennedy Space Center. The program includes a mock space shuttle mission, ride flight simulators, lunch with an astronaut and a guided tour of Kennedy Space Center with a close-up view of the space shuttle launch pads and the Apollo/Saturn V Center — the home of a 363-foot long Saturn V Moon rocket.

One First Prize winner will receive a Meade 6" ETX-LS telescope, 10 Second Prize winners will each get a 1-year subscription to Astronomy magazine, and 10 Third Prize winners will each collect a Deep Space Mysteries calendar produced by Astronomy magazine.

And even if you don’t win, you can still save $5 on admission to a 2009 trip to the Kennedy Space Center Visitor Complex. Find the coupon on page 17 of Astronomy’s August 2009 issue (on newsstands June 30), a special issue highlighting man’s potential return to the Moon by 2020.
