Sierra Nevada Corporation has awarded Aerojet RocketdyneÂ a contract to provide an electrical power system for the former’s Dream ChaserÂ commercial spacecraft designated by NASA to transport cargo to and from the International Space Station.
Aerojet Rocketdyne said TuesdayÂ itÂ will design, create, test and install the electrical power system onto Dream Chaser as well asÂ provide power conversion and distribution units and rechargeable batteries under the contract.
NASA selected Sierra Nevada, Orbital ATK and SpaceXÂ in JanuaryÂ for the second iteration of the space agency’sÂ Commercial Resupply Services program that awards participants task orders for individual flights to the ISS.
Julie Van Kleeck, Aerojet Rocketdyne’s vice president of advance space and launch, said the rechargeable batteries work toÂ support the spacecraft’s free-flight time in space andÂ its journey to and from Earth.
The company currently supportsÂ the International Space Station’sÂ own power systems and will build onÂ its experience to help develop power systems for SNC commercial missions as well asÂ NASA exploration and in-space transportation programs, said Eileen Drake, Aerojet Rocketdyne CEO and president.
Aerojet Rocketdyne will build the system toÂ regulate and distribute energyÂ from the spacecraft’s solar arrays to power avionics, thermal and propulsion systems and any electrical-powered payloads during delivery missions.
