Multilayer Cryogenic Insulation:
- Reduces propellant evaporation
- No frost formation
Liquid Hydrogen:
- High energy density - Reduces fuel required
- Zero emissions - By-product is water
- Lower cost - Petroleum independence
- Used as a "battery" to store clean energy
Sustainable Energy:
- Independent of petroleum supplies
- Lower cost - Harness nature's energy
- Environmentally friendly
Together, these technologies enable a vehicle unlike any other reusable launch vehicle being developed today. By maximizing the efficiency of the propulsion, aerodynamics, and structure, the SA reusable launch vehicle is capable of flying into space while consuming orders of magnitude less propellant. The combination of high performance and fuel efficiency will allow SA to offer spaceflight experiences with an unrivaled emphasis on safety and affordability all in an environmentally clean way. The key enabler is SA's breakthrough in propulsion technology.
