SpaceShipOne captures X-prize!

MOJAVE DESERT, California (CNN) -- SpaceShipOne climbed into space for the second time in a week to claim the $10 million Ansari X Prize.

X Prize officials said the privately funded craft reached 368,000 feet -- well into space -- Monday to win the $10 million prize.

The threshold of space is 328,000 feet.

Pilot Brian Binnie reported a shaky flight with "a little roll" but did not experience the 29 rolls Mike Melvill experienced last week.

Space ShipOne and its mother ship, the White Knight, featured a new paint job promoting Virgin Group, Richard Branson firm, which recently announced a deal to license the SpaceShipOne technology for a fleet of commercial spacecraft.It could also be the most lucrative 3 1/2 minutes in space for the Mojave Aerospace Ventures Team.

Spacecraft designer Burt Rutan told a crowd gathered at his home in the Mojave Desert on Sunday that he was confident of the success of today's flight -- and winning the $10 million Ansari X Prize check.

After some unexpected acrobatics during the last flight, Rutan said Monday's would be a smooth flight, but he was prepared for stability issues.

"We believe we have solved these and we don't believe we'll see the rolls tomorrow," he said. "But if we do, we don't believe they're dangerous. ... After all, what we're doing is research."

Binnie, who piloted the first powered SpaceShipOne launch, was at the helm of the craft after it was released from the belly of the White Knight turbojet at about 50,000 feet.

Within seconds after igniting its rocket, it was traveling faster than a bullet out of a rifle.

The spacecraft is outfitted with a stronger engine and some aerodynamic modifications from its first record-breaking flight into space on June 21.

Melvill flew the craft's first mission to space and reached, just barely, the required 62-mile altitude, passing the internationally recognized boundary of space. Wind shear and a jammed control on the tail meant the craft veered about 20 miles off course, but it returned for a smooth landing. It was only SpaceShipOne's fourth flight using the rocket engine

On Wednesday, SpaceShipOne streaked even higher to 337, 569 feet (64 miles). However, during its ascent, the private spacecraft began a series of rolls that Melvill brought under control only after ending the rocket burn 11 seconds early.

Today's suborbital flight is the second within two weeks needed to win the X Prize for the desert workshop of pilots and engineers who have continually pushed the envelope.

SpaceShipOne's thrust is provided by two innocuous substances that, when mixed together, are explosive: nitrous oxide and rubber.

A fuel tank about six feet in diameter at the center of the craft holds liquid nitrous oxide, also known as laughing gas. A hollow tube leading from the tank to the engine nozzle is filled with solid rubber. The combustive combination produces thousands of pounds of thrust, although exact amount remains secret.

Most importantly, says aerospace engineer and spacecraft designer Rutan, it has opened the world -- and a private market -- to spaceflight.

"I strongly feel that, if we are successful, our program will mark the beginning of a renaissance for manned space flight," said Rutan in an X Prize statement.

Peter Diamandis, co-founder of the X Prize Foundation, said the $10 million award is intended to spur civilian spaceflight. The nonprofit X Prize Foundation is sponsoring the contest to promote the development of a low-cost, efficient craft for space tourism in the same way prize competitions stimulated commercial aviation in the early 20th century. The prize is fully funded through the end of the year

Nice to see someone getting the X prize. I've been waiting for this day since my teacher told me about it in 8th grade. Now I'm in 12th.

thats so cool. but then again, it takes the fun out of it now.. and also means i wont be getting that particular prize anymore.... what next? im sure eventually there will be another contest with a high price prize. go to mars and back twice within 2 years? lol
and the google.com page has spaceshipone drawing on it. :D

The guy behind the X Prize, Peter Diamandis, has just announced an annual competition called the "X Prize Cup", sort of like NASCAR for spacecraft. Prize categories are expected to include altitude, speed, passenger capacity, etc.

There are already corporate sponsors lined up.

The sky's not the limit anymore!

There is a new $50 million dollar competition for an orbiting spacecraft!

I can start to imagine the problems involved with with a safe orbital flight. Basically I wonder how anyone would managed to avoid the countless numbers of space debris without it destroying anything. Im surprised NASA has never had this problem.

Are there any videos of either fights on line? I've been looking, but have not found any.

actually, i think ive heard of some debris damaging a satellite of somewhere of someone's :D sorry. cant seem to remember what or when. or if its just my imaginition..lol

google it up or click the spaceshipone drawing above the textbox for google.com youll find videos there.

Does anyone else find it slightly scary that COMPANIES will be building rockets to put normal people in space?

I mean, I'm all for innovation and pushing the envelope, but god knows how safe company xyz's rocket is. NASA does more testing than anyone could even imagine... and the price of one shuttle is astronomically high. One has to wonder how safe these things will be.

There better be some serious regulation and oversight on these bad boys.

Well, if you realy want to go to space, you would take the risk. They would probably also make you sign some sort of agreement that they take no responsibility for your death.

http://www.xprize.com has links to the final flight video. beware, it only works if you are running a windows OS!

well, they SAY they are testing alot lol... no offense..
and same thing was running through everyones minds when airplanes came out, then jets too. competition makes things go quality too. if some company loses some ship, their reputation will definitly go down. might even lose their business. so these companys will make things QUALITY. i think. even NASA screws up sometimes. (columbia, few apollos, etcetc.)

Not at all. Successful companies are in the business of making money. Injuring (or killing) their customers is something they tend to avoid.

SpaceShipOne is more like an airplane than a typical NASA spacecraft. It's a whole lot easier to test something when you can do it incrementally, without needing to have everything work absolutely correctly the first time. The entire point of the X Prize was to bring about completely reusable spacecraft.

There have been literally years of work put in by people in industry and government, working out appropriate models for regulating an emerging private space access market. One of the problems to be avoided is excessively restricting it too early and thus keeping it from developing at all. The rules for reusable spacecraft aren't going to be specifying anything much more rigorous than existing regulations for experimental aircraft anytime soon.

Too bad the first commercial jet planes fell out of the sky due to a design error. :ahh: Ever wonder why airplanes have circular windows. Well their design is traced back to the first jet liner. They were having mysterious crashes that actually grounded the plane. Aparently the planes had a fatal flaw that was discovered after extensive ground testing. The planes were failing at the point at the windows which in that plane was rectangular (which were that shape for purely asthetic reasons). After that all airplane compaines united to design a very safe jetliner. Then you have cars which did not even follow the same lines of contraversy in terms of safety. Everyone at first thought cars were safe even though they had no seatbelts or any form of protection. Of course that all changed during the 1970's?? when Ralph Nader came along. I believe he came along and said that a lot of the cars were unsafe. Im not sure of which specific brand car that he went after but the contraversy delt with the camber of the wheels which may have caused roll overs and the fact that the engine was in the front (which resulted in horrible steering). Of course some of the things Nader said were a little exaggerated but it did help start the first government crash tests. A lot of vehicles that were built were scary in terms of safety. There was one car that had two of it's safety features removed (first airbags and a bladder around gas tank) which resulted into it turning into a fire ball every time you hit the car inthe back. I could go on about how companies thought they are doing a good job at safety but weren't. NASA has a fairl good track record in terms of safety except for the fact that they keep on failing into a group think mentaility. There was two apollo missions and two shuttle missions in which the disaster could have been prevented.

The lesson to be learned from the DeHavilland Comet is not "Don't trust companies." The Comet was the first large aircraft to make regular trips to high altitude, and the problem of pressurization stress cycles was not known to anyone. A government-designed airliner wouldn't have been any less likely to suffer from the flaw.

The true lesson is more along the lines of "Walk before you run." Test the designs to find out where they break. Identify the problems. Correct the design to eliminate them. Note that every airliner since the Comet has rounded corners on the windows (and doors).

SpaceShipOne and White Knight have round windows for exactly this reason.
