Rocket Motor Tests
Successfull Spaceship Two Rocket Motor Testing
Virgin Galactic today announces the successful completion of the first phase of tests of the rocket motor that will propel space tourists, scientists and payloads into space.
In the desert of southern California, Virgin Galactic’s key supplier Scaled Composites and its subcontractor SNC (Sierra Nevada Corporation) have successfully completed the first tests of the innovative rocket motor that will propel space tourists, scientists and payloads into space. The hybrid Nitrous Oxide system being used is the largest of its kind in the world and it will send Virgin’s customers up into sub-orbital space at speeds over 2500 mph (4000kmh), to heights over 65 miles (110km) above the Earth’s surface, before the spaceship descends back down through the atmosphere using its pioneering feathered re-entry system.
Sir Richard Branson, founder of Virgin Galactic said: “As Virgin Galactic gets ever closer to the start of commercial operations, we are reaching and passing many important and historic milestones. The Virgin MotherShip (VMS) Eve, the first of our amazing, all carbon composite, high altitude WhiteKnightTwo launch vehicles, is flying superbly. SpaceShipTwo, which will air launch from Eve, is largely constructed and awaiting the start of its own test flight programme later this year.”
The rocket motor burns for a very short period of time because the spaceship is launched from VMS Eve in the upper atmosphere, rather than from ground level. This means much less fuel is required, and the fuel burn is more environmentally benign than the solid rockets used in most ground based systems.
While the rocket motor is extremely powerful, it is also completely controllable. This system can – if necessary – be shut down at any time, allowing the spaceship to glide back down to land at a conventional runway. This is a significant feature in the overall safety of the Virgin system for human space flight.
Sir Richard continues: “Less fuel and clean fuel all add up to a space launch system which will be completely unprecedented in its low environmental impact compared with current space flight. The spaceship’s carbon footprint for each of its passengers and crew will be about a quarter of that for a return trip from London to New York, demonstrating again the extraordinary benefits that new technology can bring to the quest for clean transportation.” “We believe space is on the cusp of a new industrial revolution. Virgin Galactic’s mission has always been to transform the safety, cost and environmental impact of access to space. Not just for passengers, but also for a range of important scientific purposes, and to send small satellites into orbit. The world’s scientific community is united in recognizing that making better use of space will be vital to mankind’s ability to manage the huge future challenges of life back here on Earth.”
The rocket motor will continue a series of exhaustive tests, and the spaceship itself will start flight testing later this year. The testing programme for the rocket, the spaceship and VMS Eve will be extensive.

I have always been a science fiction fan. I have always hoped that spaceflight would not be just a NASA (government) sponsored endeavor. Commercial spaceflight will make all things possible, from tourists participating in sub-orbital flights, to the establishment of space colonies at the La Grange points in Earth orbit, and the mining of the asteroid belt for the raw materials to feed our hungry economies. Commercial development of space will turn a tax breaking burden into a profitable venture for those who will extend mankind's reach across the Solar system. I may not see this accomplishment during my lifetime, but I have seen the beginning, and it pleases me very much. All you will need is some visionary people, a good ship, and a star to steer by. I predict you will do very well in this commercial venture. I also wish all of you the best of luck, and great profit in all your future flights. Best Regards, Fred.
