About the Company

Sierra Space

LEO space transportation, habitats, satellites

Sierra Space provides a space-as-a-service platform spanning transportation, habitats, and satellite systems for government, civil, and commercial customers in the low-Earth orbit economy. Its products include the Dream Chaser reusable spaceplane for cargo and eventual crew, the LIFE inflatable habitat for LEO, lunar, or Mars missions, and satellite buses like Velocity, Horizon, and Titan used for missile warning and tracking under SDA contracts. Unlike many space firms, Sierra Space offers an end-to-end suite—spaceplane transport, habitable modules, and satellite platforms—integrated under one platform and backed by decades of spaceflight heritage, including collaboration on Orbital Reef with Blue Origin. Its goal is to enable a growing LEO economy by delivering integrated infrastructure and services that support government missions, commercial activity, and national security space capabilities.
