Pratt & Whitney Rocketdyne and RD AMROSS successfully propelled the
Radiation Belt Storm Probes (RBSP) mission into orbit, once again
demonstrating the consistency and reliability of their rocket launch
propulsion systems. The mission launched from Cape Canaveral Air Force
Station in Florida on a United Launch Alliance Atlas V rocket. The
Atlas V is powered by the RD AMROSS RD-180 booster engine, and the
upper-stage is powered by the Pratt & Whitney Rocketdyne RL10
engine. RD AMROSS LLC is a joint venture of Pratt & Whitney
Rocketdyne and NPO Energomash.
Built and managed by the Johns Hopkins University Applied Physics
Laboratory, the RBSP includes two spacecraft designed to fly in
elliptical orbits to study the planet’s radiation belts and help
scientists better understand the sun’s influence on the Earth and
near-Earth space. The mission is part of NASA’s Living with a Star
Geospace program to explore fundamental processes that operate
throughout the solar system, in particular those that generate hazardous
space weather effects near the Earth and phenomena that could affect
solar system exploration.
The Atlas V Centaur upper-stage is powered by a single
RL10A4-2 engine that delivers 22,300 pounds of thrust. The Atlas V
Common Core booster is powered by the RD-180 engine and delivers nearly 1
million pounds of thrust.

The Economiser Electric Radiator is not to be confused with a storage heater, nor a panel or convection heater or liquid filled variant. Electric storage heaters are uncontrollable and bulky, whilst the other options are costly to use. The heat output of Economiser Radiators is near instantaneous, but the short-term storage capacity of the internal ceramic cells allows for a fully controlled release of stored heat through a balanced combination of radiant, and naturally convected warmth.
