Virgin Galactic Rocket Motor Testing Successful

This morning, Virgin Galactic announced the successful completion of the first phase of tests of the rocket motor that will propel space tourists, scientists and payloads into space.

The company is selling trips to space, for around $200,000 and plans to launch flights from Spaceport America in Southern New Mexico beginning in 2010.

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 continued:
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.

Virgin Galactic's mission is 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 recognising 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.

A One Way Trip on Virgin Galactic (or Tricks in Post-Apocalyptic Space) [Bonus News Poem, March 7, 2010]
“Iran's Defense Ministry introduced a new domestically-manufactured cruise missile that will significantly improve the deterrence capabilities of the Iranian military forces, the local satellite Press TV reported on Sunday.”

“SpaceShipTwo will be unveiled after darkness has fallen over the Mojave Desert to the sound of a space-themed anthem from Britain’s biggest DJs, Above & Beyond. Fittingly titled “Buzz” the track will sample Buzz Aldrin’s original moon landing dialogue. Following the naming by Governors Richardson and Schwarzenegger, the DJs will also perform an exclusive set at the celebration cocktail party which will follow and feature the first ever IceBar in the desert hosted by Absolut and the world famous Swedish IceHotel. All the guests will be protected from the desert cold by designer space jackets supplied by PUMA. Finally, to close off the celebrations, all the guests will have the opportunity to view the stunning night skies using specialist telescopes supplied by Ron Dantowitz of the Clay Observatory whose unique tracking cameras followed SS1 into space during the epic flights of 2004.”

“Cyrus is also working on an album of her own, which she said will be out later this summer.”

The royalties won't pay for air
Much less a berth, a bite to eat—
I've waited long to touch your hair,
To paint the nails on pretty feet

Since puberty. I've thought of you...
I'm sorry does that make you shy?
I'm lonely. Since the earth's been through,
I've cursed this metal in the sky.

Celebrities like you survived
To love your fans (for price, by bit);
Though true on earth, with wealth you thrived,
In space you live by famous slit.

Your wealth on earth is molten slag
In space, your skills? They have no use.
On earth they might have let you drag
Them down, but here you'd best be loose.

Your refuge is our prison now
And servant's master, switching bows;
Now act as if it's Oscar-night
And come to me for Tantric-rites.
