Sierra Space

Sierra Space focuses on the development of innovative space technologies and participates in projects related to space exploration, including the design of space vehicles and exploration systems.

Sierra Space is a subsidiary of Sierra Nevada, which has signed an agreement with NASA to deploy unmanned flights to the International Space Station (ISS).

It has designed the Dreamchaser, whose unique airplane-like design sets it apart from other spacecraft. The Dream Chaser is a fully autonomous, reusable orbital aircraft designed to transport cargo to destinations in low Earth orbit (LEO). Measuring about a quarter the size of a space shuttle, it features autonomous launch, flight and landing capabilities.

At the same time, the company is working on a manned version of the Dream Chaser. This future version will be used to join the Orbital Reef space station, a project currently under development with other companies in the sector, including Blue Origin and SpaceX. Orbital Reef could be operational in 2027, and could see its surface area increased thanks to inflatable modules implanted to offer astronauts more space.
