New Space Race Heats Up
LOS ANGELES (AP) - Aerospace engineers have been holed up in a Mojave Desert
hangar for four years, fashioning a commercial spaceship to loft rich tourists
some 62 miles above Earth. Now the wraps come partially off the top-secret project.
British billionaire Sir Richard Branson and American aerospace designer Burt
Rutan are due to show off their mothership, which is designed to air launch
a passenger-toting spaceship out of the atmosphere.
The rollout - a year after a deadly accident at Rutan’s test site - marks
the start of a rigorous flight test program that space tourism advocates hope
will climax with the first suborbital joy rides by the end of the decade. More
than 250 wannabe astronauts have paid $200,000 or put down deposits for a chance
to float weightless for a mere five minutes.
“
Having invested all my faith in it, I’m so excited to see the actual thing,” said
artist Namira Salim, a customer who is lined up for a ride on Branson’s
Virgin Galactic.
The last time there was this level of buzz in the high desert north of Los
Angeles was in 2004, when throngs of spectators gathered to witness SpaceShipOne
capture
the $10 million Ansari X Prize by becoming the first private, manned craft
to reach space. It was designed by Rutan and bankrolled by Microsoft Corp.
co-founder
Paul Allen.
SpaceShipOne ushered in a new space age dominated by deep-pocketed entrepreneurs
with dreams of making space voyages as mundane as airplane travel. That vision
remains unfulfilled.
Among the new space entrepreneurs is the swashbuckling Branson, who teamed
with Rutan’s publicity-shy Scaled Composites LLC to commercialize SpaceShipOne.
Its successor, SpaceShipTwo, is being designed out of the public eye, along
with the carrier aircraft White Knight Two.
“
They’ve been hyping this and selling tickets,” said Alan Radecki,
a helicopter mechanic and aviation photographer who follows the private space
race. “This is the first time they’re going to have hardware to
show people.”
Branson previously heralded 2008 as the “Year of the Spaceship.” In
January, he and Rutan offered a sneak peak of their commercial partnership,
showing off scale models of the mothership and the spacecraft it will launch.
Though technical details remain guarded, tidbits about the vehicles have trickled
out: The twin-fuselage White Knight Two will have the same wingspan - 140 feet
- as the Boeing B-29 Superfortress, a World War II bomber.
It will launch SpaceShipTwo, which will be the size of a corporate Gulfstream
capable of carrying six passengers and two pilots. Both will be built wholly
from ultra-light composite material. Flight testing is slated for the end of
September.
Meanwhile, SpaceShipTwo is only about 70 percent complete, said Virgin Galactic
president Will Whitehorn.
Observers of the infant private spaceflight industry are encouraged by the
progress, but note that the main attraction - the actual spaceship that will
carry passengers
- is yet to come.
“
It’s a positive step forward,” said space analyst John Logsdon of
George Washington University. “The real indication of progress will be
showing a spaceship that’s on the path that’s ready to fly.”
The unveiling comes a year after an explosion at Scaled Composites’ test
site killed three technicians. The company, now owned by Northrop Grumman Corp.,
is appealing a state fine of $28,870 for workplace violations in connection with
the blast, which occurred during the development of SpaceShipTwo’s propellant
system.
Exactly when tourists will experience zero gravity or see Earth’s curvature
is unknown, but the project already lags Virgin Galactic’s 2004 prediction
that passengers would be in space last year.
Whitehorn declined to set a date for commercial travel, but he said the earliest
flights to space could be late 2009 or early 2010. The maiden voyage has been
reserved for Branson and his family; Virgin Galactic plans to rename the aircraft “Eve” after
Branson’s mother, a former glider pilot instructor and flight attendant.
Plans call for White Knight Two to carry SpaceShipTwo 50,000 feet in the
air, tucked beneath its single 140-foot wing, before releasing it. SpaceShipTwo
will then power its hybrid rocket and climb into space. Before gliding back
to Earth,
it will use a Rutan-designed “feathering” technique - in which
the wings are rotated upward from the fuselage to reduce the heat of re-entry.
The 2-1/2 hour trip is expected to include about five minutes of weightlessness.
