Quick Facts
About Sierra Space
Sierra Space is a commercial space company developing the Dream Chaser spaceplane, Orbital Reef commercial space station, and related space technologies. Spun off from Sierra Nevada Corporation in 2021, Sierra Space is based in Louisville, Colorado, and aims to build commercial infrastructure in low Earth orbit to support NASA, commercial, and international customers.
Sierra Space operates as a privately held company backed by strategic investors including General Atlantic, Coatue, and Moore Strategic Ventures. The company employs approximately 1,500 people and is led by CEO Tom Vice. Sierra Space positions itself as a leader in the commercialization of low Earth orbit.
History and Milestones
Sierra Nevada Corporation's Space Systems group developed the Dream Chaser vehicle beginning in 2004, based on NASA's HL-20 lifting body design. The spacecraft competed for NASA's Commercial Crew Program but was not selected. Sierra Nevada pivoted to cargo delivery, winning a Commercial Resupply Services-2 contract in 2016.
Sierra Space was established as a separate company in 2021 to focus on commercial space opportunities beyond government contracts. The spinoff attracted significant private investment, valuing the company at over $4.5 billion.
In 2021, Sierra Space partnered with Blue Origin to propose Orbital Reef, a commercial space station selected by NASA's Commercial LEO Destinations program. This partnership positions Sierra Space as a potential successor to the International Space Station.
Products and Services
Dream Chaser is a reusable lifting-body spaceplane designed to deliver cargo to the International Space Station and future destinations. The vehicle launches atop a ULA Vulcan Centaur or Atlas V rocket and returns to Earth with a runway landing, enabling rapid payload recovery. Dream Chaser carries both pressurized and unpressurized cargo.
The LIFE (Large Integrated Flexible Environment) habitat is Sierra Space's expandable space station module technology. LIFE modules launch compactly and inflate to provide large pressurized volume. This technology is central to Orbital Reef and could support lunar surface habitats.
Sierra Space is developing Shooting Star, a cargo module that accompanies Dream Chaser, providing additional volume for supplies and waste disposal. The company also works on space station systems, life support, and related technologies.
Technology and Capabilities
Dream Chaser's lifting body design provides cross-range capability during reentry, enabling landing at multiple locations. The spacecraft is designed for gentle returns (1.5 g maximum), suitable for sensitive cargo including biological experiments. Dream Chaser can land on commercial runways at non-federal spaceports.
LIFE habitat technology uses advanced materials to create expandable structures that provide more volume per launch than traditional rigid modules. Sierra Space has conducted full-scale burst tests demonstrating the technology's structural integrity and safety margins.
The company develops life support, thermal control, and power systems for space habitats. Sierra Space also works on in-space manufacturing technologies, including plans for industrial facilities aboard Orbital Reef.
Business and Financial Overview
Sierra Space raised approximately $1.4 billion in private funding, including a 2021 Series A at a $4.5 billion valuation. The company generates revenue from NASA contracts, including the Commercial Resupply Services agreement for Dream Chaser cargo flights.
Major contracts include NASA CRS-2 (at least six Dream Chaser cargo missions), Commercial LEO Destinations funding for Orbital Reef, and various technology development awards. The company seeks additional commercial and international customers for Dream Chaser and space station services.
Sierra Space competes for astronaut and cargo transportation services while developing commercial space station offerings. The company's path to profitability depends on successful Dream Chaser operations and Orbital Reef development.
Recent Developments
In 2024, Sierra Space prepared for the first Dream Chaser mission, completing spacecraft integration and testing. The inaugural flight to the International Space Station was targeted for launch on ULA's Vulcan Centaur rocket.
The company advanced Orbital Reef development, conducting system design reviews and component testing. Sierra Space also expanded its LIFE habitat program, completing additional structural tests and advancing manufacturing capabilities.
Sierra Space strengthened international partnerships and explored additional commercial applications for its technologies. The company also invested in workforce development and facilities expansion to support upcoming operations.
Market Position
Sierra Space positions itself as a commercial space infrastructure provider, distinct from launch companies like SpaceX or satellite operators. The Dream Chaser and Orbital Reef represent comprehensive solutions for low Earth orbit commercialization.
Key competitors include SpaceX (for cargo services and potentially stations), Axiom Space (for commercial space stations), and other companies developing LEO infrastructure. Sierra Space's reusable spaceplane technology offers unique capabilities for cargo return.
Competitive advantages include the Dream Chaser's gentle return capability, expandable habitat technology, and diverse technology portfolio. Strategic partnerships with Blue Origin for Orbital Reef and ULA for launch services strengthen the company's position.
