A new private spaceship is one step closer to flying its first
passengers after acing a spectacular test flight over the California
desert last week.
Virgin Galactic's suborbital SpaceShipTwo successfully conducted its first "cold flow" flight test
above the Mojave Desert last Friday (April 12). During the test,
oxidizer was run through the rocket's propulsion system and out the back
nozzle of the ship, though the vehicle's rocket engine was not turned
on.
"As well as providing further qualifying evidence that the rocket
system is flight-ready, the test also provided a stunning spectacle due
to the oxidizer contrail and for the first time gave a taste of what SpaceShipTwo will look like as it powers to space," Virgin Galactic officials wrote in a statement. [See Photos of Virgin Galactic's Test Flights ]
During the most recent test — which comes on the heels of the ship's 24th successful drop test on April 3 — the space plane was flown high into the sky by WhiteKnightTwo,
its carrier aircraft. After being released from the plane, SpaceShipTwo
glided smoothly back to the ground, leaving a contrail of oxidizer in
its wake.
The next big step for the commercial spaceflight company appears to be conducting a full flight test, igniting the rocket in the air.
"The upcoming first powered flight of SpaceshipTwo is in many ways the most significant milestone to date, being the first time that the spaceship has flown with all systems installed and fully operational," Virgin Galactic officials wrote.
The company has not released an expected date for a powered test flight.
Once SpaceShipTwo is operational, WhiteKnightTwo will carry the vehicle up to an altitude of about 50,000 feet (15,240 meters) before releasing it.
After separation, SpaceShipTwo will accelerate to 2,500 mph (4,000 km/h) and eventually pass an altitude of 62 miles (100 kilometers), the point at which passengers are considered astronauts. The spaceship will reach a peak altitude of 68 miles (110 km), giving the six passengers and two pilots about five minutes of weightlessness. Upon re-entry, SpaceShipTwo will be able to land on a conventional runway.
A seat on board a SpaceShipTwo flight costs $200,000. More than 550 people have put down deposits to reserve a spot, company officials say.
Virgin Galactic was founded by British billionaire Sir Richard Branson in 2004 to offer private trips to space for paying passengers. The company's SpaceShipTwo vehicles and their giant WhiteKnightTwo carrier aircraft were developed by the Mojave, Calif.-based company Scaled Composites.
