The Radiation Belt Storm Probes (RBSP) mission is scheduled to launch next Thursday, August 23, on an Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The launch window opens at 4:08 a.m. EDT and closes at 4:28 a.m. EDT; you can watch the launch on NASA TV or at http://www.nasa.tv/ntv.
The RBSP mission is made up of two identical probes that will study the Van Allen Radiation Belts, two concentric, donut-shaped rings of high-energy particles that surround Earth. Data from the probes will help us understand this major feature of the Earth’s magnetosphere and the interactions between the sun and Earth.
As the second mission in NASA's Living With a Star program, the twin RBSP spacecraft are part of a fleet of spacecraft that may help predict space weather before it affects our spacecraft in orbit and the surface of our home planet.
