Company Description

Sierra Space is an aerospace company that develops solutions for space transportation, national security, and scientific collaboration. The company's current activities include manufacturing satellite platforms for the Space Development Agency’s missile tracking layer, developing the Dream Chaser reusable spaceplane for cargo missions, and creating modular space habitats like the Large Integrated Flexible Environment (LIFE) Habitat. Founded in 2021, Sierra Space is a subsidiary of the Sierra Nevada Corporation and builds upon its parent company's more than three decades of experience, which includes supporting over 500 space missions.

The company is advancing on several key projects. Its Dream Chaser spaceplane recently completed critical pre-flight tests at NASA’s Kennedy Space Center, with a first free-flyer demonstration mission targeted for late 2026. In its defense-related work, Sierra Space completed the first satellite structure for the Space Development Agency’s Tranche 2 Tracking Layer program three months ahead of schedule in early 2024. The company also provides critical components for other space missions; its parts were used on the HTV-X1 vehicle that successfully docked with the International Space Station in late 2023.
