NASA Selects Orbital Reef to Develop Space Station Replacement

December 2, 2021 – Orbital Reef, led by partners Blue Origin and Sierra Space, was selected today by NASA for a funded Space Act Agreement for collaboration to design a commercially owned and operated space station in low Earth orbit (LEO). NASA’s Commercial LEO Development program aims to shift NASA’s research and exploration activities in LEO to commercial space stations, helping stimulate a growing space economy before the International Space Station is retired. The Orbital Reef team includes Boeing, Redwire Space, Genesis Engineering Solutions, and Arizona State University.


Single Person Spacecraft


The Single Person Spacecraft (SPS) is an example of our ongoing investment in R&D. The SPS provides a unique alternative to the concept of a spacesuit. When extra-vehicular activity (EVA) in space has required an astronaut with spacesuit there are inherent challenges. The SPS has advantages for both the astronaut and the overall activities that need to be accomplished.


Designed for servicing / exploration of ISS, NEOs and satellites. It can be piloted or tele-operated. Using the same atmosphere as the host vehicle it provides immediate access to space without pre-breathing or airlock. Integral propulsion enables rapid transport to the work site. It is designed for all sizes of crew members providing “shirt sleeve” operations of conventional displays and controls.
