We build rockets to launch small satellites.
RS1 is a resilient launch vehicle purpose-built for the high-cadence, low-cost, no-fuss future of orbital launch. Dirt-simple tank architecture and pressurization systems simplify manufacturing and launch operations. Staged combustion engines provide a time-tested route to high ISP. Metallic structures and proven methods of manufacture minimize technical risk.
RS1 is the rocket you build when you focus on the only true design constraint: it has to work.
Stage 1 Engines
2x Ripley LRE
Stage 2 Engines
Oxidizer-rich Staged Combustion (ORSC)
- 900kg max
- 800kg to 500km low-inclination orbit
- 650kg to 500km sun-synchronous orbit
- Multi-burn 2nd stage for complex missions
RS1 provides a 4x reduction in cost per kilogram from current operational vehicles under 1000kg capacity and the lowest cost per kilogram of any announced vehicle in that class.
- Price: $17mm
- Price/kg to 200km: $20,000
- Price/kg to 500km: $26,000
RS1 offers a class-leading fairing volume that can accommodate a variety of small satellite configurations.
- No fixed infrastructure
- Truck-mounted ground systems
- Field serviceable flight systems
- One week call-up time
