The Columbia Memorial Space Center is a hands-on learning center that is dedicated to bringing the wonder and excitement of space science to children of all ages.  We also serve as the national memorial for the Space Shuttle Columbia’s seven crew members, lost in 2003.  Located in Downey, California, we strive to be the most accessible space science center in the Los Angeles area.  Our 20,000 square foot visitor center is equipped with not only amazing technology and visual teaching exhibits, but also a friendly staff and atmosphere to help make them more enjoyable.  Plus, we’re constantly holding classes and workshops, so be sure to check out our calendar for updates

The Space Center also hosts one of over 48 Challenger Learning Centers on the planet, and the only CLC in the greater Los Angeles area.  When operating, you can “Return to the Moon”, “Rendezvous With a Comet”, or go on a “Voyage to Mars,” and experience the real-life excitement of working in Mission Control or in the Spacecraft.  Our CLC is available for field trips, team-building exercises, and parties of 16 or more.
