The Van Allen Probes (formerly known as the Radiation Belt Storm Probes (RBSP)) are two robotic spacecraft being used to study the Van Allen radiation belts that surround Earth. NASA is conducting the Van Allen Probes mission as part of the Living With a Star program. Understanding the radiation belt environment and its variability has important practical applications in the areas of spacecraft operations, spacecraft system design, mission planning and astronaut safety.〔(Radiation Belt Storm Probes (RBSP) )〕 The probes were launched on August 30, 2012. ==Overview== NASA's Goddard Space Flight Center manages the overall Living With a Star program of which RBSP is a project, along with Solar Dynamics Observatory (SDO). The Applied Physics Laboratory is responsible for the overall implementation and instrument management for RBSP. The primary mission is scheduled to last 2 years, with expendables expected to last for 4 years. The spacecraft will also work in close collaboration with the Balloon Array for RBSP Relativistic Electron Losses (BARREL), which can measure particles that break out of the belts and make it all the way to Earth's atmosphere.〔(Balloon Array for RBSP Relativistic Electron Losses )〕 The Radiation Belt Storm Probes mission is part of NASA’s Living With a Star program, which is managed by Goddard Space Flight Center in Greenbelt. The Johns Hopkins University Applied Physics Laboratory (APL) manages the mission and is building and will operate the Van Allen Probes for NASA.
