NASA's Radiation Belt Storm Probes (RBSP)
is the first twin-spacecraft mission designed to explore our
Earth's radiation belts. It was launched on an Atlas V rocket on
Thursday 30 August, 2012 at 4:05 am EDT at Cape Canaveral Air
Force Station's Space Launch Complex 41.
Allen Probes Reveal a New Radiation Belt Around Earth
NASA's Van Allen
Probes mission has discovered a previously unknown third radiation
belt around Earth, revealing the existence of unexpected
structures and processes within these hazardous regions of space.
Previous observations have shown two distinct regions of trapped
radiation surrounding our planet. Particle detection instruments
aboard the twin Van Allen Probes, launched August 30 2012, quickly
revealed to scientists the existence of this new, transient, third
The Van Allen Probes (Radiation Belt Storm Probes)
will study changes in Earth's space environment caused by the sun
(space weather) that can disable satellites, create power grid
failures and disrupt GPS service. The mission also will allow
researchers to understand fundamental radiation and particle
acceleration processes throughout the universe. The Van Allen
Probes (Radiation Belt
Storm Probes) is the second NASA mission under the Living
With a Star program.

Both satellites contain five
science instruments inside their eight-sided frames, which are
about 6 feet across (1.8 m), 3 feet high (0.9 m) and weigh a
total of 1,475 pounds (670 kg) each.
The mission duration is 2 years.
Note: Originally Van Allen Probes
were named NASA's Radiation Belt Storm
Probes (RBSP) .

Launch was scrubbed on Saturday
25 August due to weather conditions associated with lightning, as
well as cumulus and anvil clouds and unfavorable weather forecast
due to Tropical Storm Isaac. The team decided to roll the Atlas V
vehicle back to the Vertical Integration Facility to ensure the
launcher and twin RBSP spacecraft are protected and secured from
the weather. The launch was rescheduled to Thursday, August 30 at
4:05 a.m. Eastern Daylight Time.

On 9 November 2012, NASA renamed the
Radiation Belt Storm Probes to the Van Allen Probes in honor of
James Van Allen, the scientist who helped launch the field of
magnetospheric science. The Van Allen Probes have turned on and
tested all instruments and are beginning their prime science
