Orbital Space Flight
ATK provides the innovative Athena III launch vehicle for the PlanetSpace team. It is based on propulsion with demonstrated
performance on multiple launch vehicles. The first stage is a 2.5 segment derivative of the Space Shuttle’s four-segment Solid Rocket Booster
(SRB). The second stage is the ATK CASTOR®120, utilized on the Athena I, Athena II and Taurus I launch vehicles. That foundation is topped
by an ATK CASTOR 30 third stage and a flight-proven Orbit Adjust Module.
Lockheed Martin Space Systems Company, using its vast interplanetary, autonomous spacecraft design, manufacturing, system integration,
and mission operations experience is developing the Orbital Transfer Vehicles for PlanetSpace.
Boeing’s role on the team includes providing cargo carrier development, cargo integration services, and ISS integration and operations
support. Boeing's Space Exploration division's legacy began with the X-15, spans Gemini, Apollo and Skylab, and continues with the space shuttle
and the International Space Station.
