Microsoft co-founder, entrepreneur, and philanthropist Paul G. Allen and aerospace pioneer Burt Rutan have reunited to develop the next generation of space travel. Mr. Allen and Mr. Rutan, whose SpaceShipOne was the first privately-funded, manned rocket ship to fly beyond earth’s atmosphere, are developing an air-launch system to provide orbital access to Space.
Allen’s new company, Stratolaunch Systems, will build a mobile launch system with three primary components: a] A carrier aircraft, developed by Scaled Composites, the aircraft manufacturer and assembler founded by Rutan. It will be the largest aircraft ever flown; b] A multi-stage booster, manufactured by Elon Musk’s Space Exploration Technologies; and c] A state-of-the-art mating and integration system allowing the carrier aircraft to safely carry a booster weighing up to 490,000 pounds. It will be built by Dynetics, a leader in the field of aerospace engineering.
Stratolaunch Systems will bring airport-like operations to the launch of commercial and government payloads and, eventually, human missions. Plans call for a first flight within five years. Stratolaunch Systems CEO and President Gary Wentz, a former chief engineer at NASA, said the system’s design will revolutionize space travel.
Mr. Rutan, who has joined Stratolaunch Systems as a board member, said he was thrilled to be back. “Paul and I pioneered private space travel with SpaceShipOne, which led to Virgin Galactic’s commercial suborbital SpaceShipTwo Program. Now, we will have the opportunity to extend that capability to orbit and beyond,” he said.
The Stratolaunch system will eventually have the capability of launching people into low earth orbit. But the company is taking a building block approach in development of the launch aircraft and booster, with initial efforts focused on unmanned payloads. Human flights will follow, after safety, reliability and operability are demonstrated.
The carrier aircraft will operate from a large airport/spaceport, such as Kennedy Space Center, and will be able to fly up to 1,300 nautical miles to the payload’s launch point. It will use six 747 engines, have a gross weight of more than 1.2 million pounds and a wingspan of more than 380 feet. For takeoff and landing, it will require a runway 12,000 feet long. Systems onboard the launch aircraft will conduct the countdown and firing of the booster and will monitor the health of the orbital payload.
The plane will be built in a Stratolaunch hangar which will soon be under construction at the Mojave Air and Space Port, said the company.
Former NASA Administrator Mike Griffin, also a Stratolaunch board member, joined Allen and Rutan at a press conference in Seattle to announce the project.
