The suborbital space transportation industry took one of its biggest steps to date this morning, with the first powered test flight of Virgin Galactic’s SpaceShipTwo, the complete details of which are included in the press release below.  Coming as it does in the same month which saw Orbital Sciences complete the first launch of the Antares booster,   and looking forward to further developments from SpaceX and XCOR later this year, it should not be lost on anyone that we are, at last,  entering a very interesting, and perhaps definitive era in humanity’s  attempt to establish a permanently expanding space economy.  There will no doubt be disappointing days ahead, and if we have learned anything from the emergence of the NewSpace movement, it is that things simply take more time, frequently quite a bit more of it,  than most would like.  

Nevertheless, on the subject of time,  and  in  appreciation of a  year which might just change everything,  in the words  of the one Earth city which distant  generations will no doubt still travel to, even  from around the solar system, to eat,  drink, dance and generally enjoy life,   “Laissez lez bon temps roulez.”  Let the good times roll, and welcome to the NewSpace age.

VIRGIN GALACTIC BREAKS SPEED OF SOUND IN FIRST ROCKET-POWERED FLIGHT OF SPACESHIPTWO

Sir Richard Branson witnesses vehicle-proving milestone

as company sets year-end goal for spaceflight

MOJAVE, Calif. – Today, Virgin Galactic, the world’s first commercial spaceline owned by Sir Richard Branson’s Virgin Group and Abu Dhabi’s aabar Investments PJC, completed the first rocket-powered flight of its space vehicle, SpaceShipTwo (SS2). The test, conducted by teams from Scaled Composites (Scaled) and Virgin Galactic, officially marks Virgin Galactic’s entrance into the final phase of vehicle testing prior to commercial service from Spaceport America in New Mexico.

“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, who was on the ground in Mojave to witness the occasion. “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.”

The test began at 7:02 a.m. local time when SS2 took off from Mojave Air and Space Port mated to WhiteKnightTwo (WK2), Virgin Galactic’s carrier aircraft. Piloting SS2 were Mark Stucky, pilot, and Mike Alsbury, co-pilot, who are test pilots for Scaled, which built SS2 for Virgin Galactic. At the WK2 controls were Virgin Galactic’s Chief Pilot Dave Mackay, assisted by Clint Nichols and Brian Maisler, co-pilot and flight test engineer, respectively, for Scaled.

Upon reaching 47,000 feet altitude and approximately 45 minutes into the flight, SS2 was released from WK2. After cross-checking data and verifying stable control, the pilots triggered ignition of the rocket motor, causing the main oxidizer valve to open and igniters to fire within the fuel case. At this point, SS2 was propelled forward and upward to a maximum altitude of 55,000 feet. The entire engine burn lasted 16 seconds, as planned. During this time, SS2 went supersonic, achieving Mach 1.2.

“We partnered with Virgin Galactic several years ago with the aspiration to transform and commercialize access to space for the broader public,” said His Excellency Khadem Al Qubaisi, Chairman of aabar Investments PJC. “Today’s test is another key milestone in realizing that

aspiration. Our partnership goes from strength to strength, and is an excellent example of aabar’s desire to participate in the development of world class technologies that are commercially viable and strategically important, both for the company, its shareholders, and for Abu Dhabi.”

The entire rocket-powered flight test lasted just over 10 minutes, culminating in a smooth landing for SS2 in Mojave at approximately 8 a.m. local time.

“The rocket motor ignition went as planned, with the expected burn duration, good engine performance and solid vehicle handling qualities throughout,” said Virgin Galactic President & CEO George Whitesides. “The successful outcome of this test marks a pivotal point for our program. We will now embark on a handful of similar powered flight tests, and then make our first test flight to space.”

In the coming months, the Virgin Galactic and Scaled test team will expand the spaceship’s powered flight envelope culminating in full space flight, which the companies anticipate will take place before the end of 2013.

“I’d like to congratulate the entire team,” said President of Scaled Kevin Mickey. “This milestone has been a long time coming and it’s only through the hard work of the team and the tremendous support of Virgin Galactic that we have been able to witness this important milestone. We look forward to all our upcoming tests and successes.”
