Legacy
Explorer 1 was the first of the long-running Explorer program. A follow-up to the first mission, Explorer-1, was successfully launched aboard a Delta II rocket in late October, 2011. The PRIME was built using modern satellite construction techniques. The orbiting satellite was a backup, since the initial Explorer-1 PRIME, launched on March 4, 2011, failed to reach orbit due to a problem in the launch vehicle.
An identically-constructed flight backup of Explorer 1 is on display in the Smithsonian Institution's National Air and Space Museum, Milestones of Flight Gallery in Washington, DC.
