The world's largest space attraction features dozens of interactive exhibits surrounding Apollo, Mercury and Space Shuttle spacecraft. Rockets developed in Huntsville range from the Army boosters that put America's first satellite and astronauts in orbit to NASA's Saturn V moon rocket and the Space Shuttle. See the U.S. Space Camp Training Center where youngsters of all ages (and adults) conduct simulated missions. Experience three times the force of gravity as you spin in the "G-Force Accelerator." Feel the powerful G forces of launch aboard the "Space Shot." Maneuver through space aboard the "Mission to Mars." Travel through space during breathtaking shows in the INTUITIVE® Planetarium and National Geographic Theater. Plan to spend an entire day at Alabama's number-one attraction.
