The test broke the speed of sound

Virgin Galactic successfully completed the first rocket-powered test flight of its space vehicle, SpaceShipTwo (SS2) -- which means it's now in the final phase of vehicle testing.

The test was conducted by Virgin Galactic and Scaled Composites from Mojave Air and Space Port in Mojave, California. The test began at 7:02 a.m. PST when SS2 took off while connected to WhiteKnightTwo (WK2), Virgin Galactic’s carrier aircraft.

Around 45 minutes later, SS2 reached an altitude of 47,000 feet and disconnected from WK2. Pilots then triggered the rocket motor, which opened the main oxididizer valve and fired igniters within the fuel case. 

SS2 propelled forward to 55,000 feet, with the engine burn lasting a total of 16 seconds. During that time, SS2 went supersonic -- reaching Mach 1.2.

SS2 landed around 8 a.m. PST.


“The first powered flight of Virgin Spaceship Enterprise was without any doubt, our single most important flight test to date,” said Virgin Galactic Founder Sir Richard Branson. “For the first time, we were able to prove the key components of the system, fully integrated and in flight. Today’s supersonic success opens the way for a rapid expansion of the spaceship’s powered flight envelope, with a very realistic goal of full space flight by the year’s end. We saw history in the making today and I couldn’t be more proud of everyone involved.”

Branson was present for today's test, but stayed on the ground to observe. 

Virgin Galactic now plans to conduct a full space flight before the end of 2013 with more testing on the way. It plans to offer a commercial service from Spaceport America in New Mexico.

Earlier this month, SS2 completed another successful test flight where it glided with oxidizer flowing through its engine.

I don't see how this is news worth being plastered on every tech blog. It only flew to 55,000 ft which is barely any higher than any big jet. The global hawk drone can fly higher than this. It's just PR BS.

I guess when this private companmy starts making flights into space they shouldn't report that either because USA and russia and a host of other countries already have space programs that can put rockets into space.

It's a test... Or do you actually think that this thing has been designed to fly to 55,000 feet and that's it? Last i read it had a projected performance of going to something like 110km, and last i checked, that was what would be called space.

You do understand that this is how machines are tested right? To make sure that the thing actually works before pushing it to it's limits.

Yes, if it's not farther than Voyager, I don't see the need to report about it either. </sarcasm>

Concorde was cruising across the Atlantic regularly at an altitude of around 17 km (56,000ft) and a sustained 2,160 km/h (Mach 2.0) just a few years ago, while carrying upwards of 100 passengers.

That makes a short-duration peak altitude of 55,000ft and peak speed of Mach 1.2 of this SS2 test rather irrelevant.

Of course when SS2 enters service, it will reach ~110 km altitude and a speed of 4,000 km/h which are both a lot higher, but it only carries six passengers, and you land at the same place you took off from. It's only purpose is to offer some six minutes of weightlessness, a short time of which is in what is considered "space" (>100 km).

At a planned ticket cost of US$200,000 for the SS2, you could fly across the Atlantic around ten times in Concorde (including inflation on the ticket cost), if it were still flying. Money would be better spent on supersonic airline development than the novelty flight that SS2 offers.

It WOULD make it irrelevant... if SS2 was using the same tech, same size, same weight as the Concorde. One might as well complain about the performance of ARM chips because Intel outperforms 'em.
