Sierra Space
Overview
Spinout from Sierra Nevada Corporation in 2021. Core products: Dream Chaser winged spaceplane (CRS-2, first flight late 2026) and LIFE inflatable habitat for Orbital Reef and commercial stations. Raised $2.25B+ across three rounds (Series A 2021, B 2023, C 2026). CRS-2 contract amended in Sept 2025 — no longer guaranteed 6 ISS docking missions; first flight is now a free-flying orbital demonstration.
Moat: Dream Chaser is the only winged orbital spacecraft under development — enabling runway landing and return of sensitive or time-critical cargo that ballistic capsules cannot. LIFE inflatable habitat design is one of the most advanced commercial LEO habitat concepts. Orbital Reef partnership with Blue Origin creates a bundled station+transportation offering.

Top Risks
- CRS-2 contract amended Sept 2025: ISS docking requirement removed; NASA ISS retirement by 2030 compresses the market window
- Dream Chaser first flight delays compound budget burn; 5+ years behind original schedule
- Vulcan Centaur launch vehicle dependency (Dream Chaser is a Vulcan payload)
- ULA's Vulcan cadence delays could push Dream Chaser launch further into 2027
