Array Deployment

The identical Van Allen Probes follow similar orbits that take them through both the inner and outer radiation belts. The highly elliptical orbits range from a minimum altitude of approximately 373 miles (600 kilometers) to a maximum altitude of approximately 23,000 miles (37,000 kilometers).

Separation

This artist rendering shows the twin Van Allen Probes as they appeared shortly after they separated from their launch vehicle, before they have moved apart from each other and deployed their solar panels and booms.

Van Allen Probes: From the Applied Physics Laboratory to Kennedy Space Center

The photos here chronicle the April 30-May 1 voyage of NASA's twin Van Allen Probes from Building 23 of the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. to Kennedy Space Center, Florida. The spacecraft, packed securely into their round white transportation containers, were taken from the thermal vacuum testing area at APL and loaded onto a flatbed trailer. At about 10:30 p.m. on April 30, they were driven to Andrews Air Force Base, Maryland, where they were loaded onto a USAF C-17 cargo plane and flown south to Florida. After landing at 7:54 a.m. at Kennedy Space Center on May 1, the probes were unloaded from the jet and driven to Astrotech Space Operations, just outside the gates of Kennedy. There, the spacecraft were unloaded and prepared for the integration and testing of their systems and instruments. These activities lead up to final preparations for stacking the spacecraft and launch aboard a United Launch Alliance Atlas V 401 rocket on August 30, 2012. All photos: JHU/APL

Environmental Testing

Engineers at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., prepare to place Radiation Belt Storm Probes spacecraft "B" in a thermal-vacuum chamber, where they can make sure the propulsion system will stand up to the range of hot, cold and airless conditions RBSP will face in outer space. This round of testing took place in late October-early November 2010.
