Sierra Space Corp

Sierra Space Corp is a for-profit aerospace technology manufacturer headquartered in Louisville, Colorado, with additional facilities in Superior and Westminster, Colorado. The company specializes in designing, developing, and manufacturing advanced space systems and components for human spaceflight missions, lunar exploration, and defense applications. Sierra Space Corp serves as a prime contractor to NASA and the U.S. Air Force, providing specialized hardware, engineering solutions, and research support that advance space exploration and national defense objectives. The company's registered SAM.gov status expires July 22, 2026, and it maintains active engagement with multiple federal agencies through both prime and subcontractor roles.

Sierra Space Corp has secured substantial prime federal contract awards totaling over $850 million in cumulative ceiling values across numerous projects spanning life support systems, propulsion technologies, lunar logistics, computing platforms, and advanced manufacturing. Major prime contracts include a $739.97 million Other Transaction Agreement with the Air Force for the TRANCHE 2 TRACKING LAYER program (completion October 1, 2032), a $22.6 million SBIR Phase III contract with the Air Force Research Laboratory for maturation of the VR35K-A Advanced Upper Stage Engine, and a $20.15 million SBIR Phase III contract with AFRL for upper stage vortex engine enhancement. NASA has awarded the company multiple significant contracts, including a $13.2 million Cost-Plus-Fixed-Fee contract from Johnson Space Center for Advanced Spacesuit Regulators (ASR) development, a $3.62 million definitive contract from Marshall Space Flight Center for lunar logistics and mobility studies under the NextSTEP-2 program, and a $3.03 million firm fixed-price contract from Marshall Space Flight Center for design and development of low leakage cryogenic valves for liquid hydrogen applications. Additional contracts support the International Space Station through an $8.5 million cost-plus-fixed-fee delivery order for Advanced Plant Habitat (APH) sustaining engineering and a $741,000 Air Force contract for REGAL Call 003 payload reentry analysis. The company has also received numerous smaller delivery orders under existing indefinite delivery contracts for specialized services including space-hardened computing platforms, flight experimentation support, science verification testing, and environmental control system repairs. None of these prime contract awards utilized set-aside designations, reflecting competition on a full and open basis. As a subcontractor, Sierra Space Corp has provided hardware, aerospace support, solar power array panels, manual bypass valves, and technical services to prime contractors including The Johns Hopkins University Applied Physics Laboratory, Boeing, Southwest Research Institute, L3Harris Technologies, Northrop Grumman Systems Corporation, and Amentum Technology.

Sierra Space Corp has received federal grant awards focused on research and development of advanced technologies for space exploration missions. The company was awarded a $2.0 million research grant from NASA's Shared Services Center in November 2023 for development of the Hydroponic Aeroponic Nutrient Delivery in Volumetrically Efficient Garden (HandiVEG) system, designed to create compact nutrient delivery systems for future crewed missions to the Moon and Mars, with completion scheduled for February 28, 2026. Additionally, Sierra Space Corp received a $60,084 Cooperative Agreement award from the Shared Services Center in December 2024 under the Dual Use Technology Development Program, which supports collaborative resource-sharing projects between NASA and industry partners where the industry partner develops technology primarily for its own public purposes with NASA financial assistance. Both grants are structured as project grants and cooperative agreements respectively, with no set-aside designations, and are being performed at the company's Colorado facilities. These grant programs support NASA's broader objectives in life support technology development and collaborative technology advancement initiatives.

Sierra Space Corp holds a single-award Indefinite Delivery Contract (IDC) with NASA's Johnson Space Center valued at $9.9 million, awarded February 1, 2023, with an ultimate completion date of January 31, 2028. This IDC supports the provision of mass measurement devices (MMDs) and water capture devices (WCDs) for research payloads aboard the International Space Station, enabling flexible ongoing support for NASA's Exploration program and human spaceflight objectives. Under this parent IDC vehicle, Sierra Space Corp has received multiple firm fixed-price delivery orders ranging from approximately $17,000 to $1.35 million, including contracts for space-hardened multi-cloud edge computing platform implementation (ENIAC Cloud), flight experimentation support for the PH-07 program, science verification testing for the PH-08 program, and support for the VEG 05 and Mouse Habitat Unit 8 research payloads. The IDC structure allows Johnson Space Center to issue task orders for specialized technological solutions that support diverse ISS research initiatives without requiring separate competitive procurement actions for each requirement. This indefinite delivery arrangement demonstrates Sierra Space Corp's role as a trusted partner for Johnson Space Center's ongoing payload integration and research infrastructure support needs.
