Sierra Nevada Corp. will launch its Dream Chaser spacecraft on United Launch Alliance’s Atlas V rocket in International Space Station resupply missions.
Sparks, Nev.-based Sierra announced the decision July 19. Centennial, Colo.-based ULA is a 50-50 joint venture of Boeing and Lockheed Martin.
Gary Wentz, ULA’s vice president of human and commercial systems, said the company recognizes “the importance of on-time and reliable transportation of … cargo” to the space station.
Sierra Nevada was awarded a NASA contract for ISS cargo missions last year, joining Orbital ATK and SpaceX. The first Sierra Nevada-ULA launch now is set for 2020 from Cape Canaveral Air Force Station in Florida, with a second resupply mission to come in 2021.
“SNC recognizes the proven reliability of the Atlas V rocket, and its availability and schedule performance makes it the right choice for the first two flights of the Dream Chaser,” said Mark Sirangelo, corporate vice president of space systems at Sierra Nevada.
The Dream Chaser spacecraft has been in development for the past decade.
