Stratolaunch’s massive carrier aircraft performed a taxi test down runway 12-30 at the Mojave Air and Space Port on Friday afternoon.

The airplane, which is designed to air-launch rockets, appeared to make several short moves at the southeast end of the runway before beginning its taxi test. It stopped twice during the taxi test before arriving at the end of the runway.

The twin-fuselage plane veered to one side on several occasions during the test, resulting in the pilots correcting the vehicle’s path. It was not clear whether this movement was part of the test.

The aircraft, which has a wingspan of 385 ft (117.3 m), was towed backwards along the runway before being returned to its hangar.

Scaled Composites built the aircraft with funding from Microsoft billionaire Paul Allen.

In 2004, a small vehicle named SpaceShipOne built by Burt Rutan and his team at Scaled Composites and funded by Microsoft billionaire Paul Allen flew three suborbital flights, becoming the first privately-built crewed craft to exit the Earth’s atmosphere. For their efforts, Rutan and Allen won the $10 million Ansari X Prize.

Rutan quickly teamed with another billionaire, Richard Branson, to build a successor vehicle named SpaceShipTwo for Virgin Galactic that would carry two pilots and six passengers on commercial suborbital flights as early as 2007. It didn’t quite work out as planned; 14 years later, SpaceShipTwo hasn’t flown anyone to space.

Nicholas Schmidle has an interesting profile of Virgin Galactic test pilot Mark Stucky in the New Yorker that sheds some light on what’s been going on at Richard Branson’s space company. I’ve excerpted some interesting passages below.

If you’ve been watching the videos of  SpaceShipTwo VSS Unity‘s first three powered flights and thinking to yourself, Gee, it looks like that thing really wants to roll…well, you’d be right. Here’s an account of the first flight on April 5.

The preliminaries are over. And now the moment of truth has arrived for Richard Branson’s Virgin Galactic.

Almost 3.5 years after SpaceShipTwo Enterprise broke up during a flight test on Halloween 2014, the company is scheduled to conduct the first powered flight of SpaceShipTwo Unity later this morning from the Mojave Air and Space Port in California. The test was preceded by seven glide flights.

I’ll be providing live updates on the flight on Twitter @spacecom.

On the morning of Oct. 31, 2014, a nightmarish vision that had haunted me for months became a real-life disaster in the skies over the Mojave Desert. SpaceShipTwo dropped from its WhiteKnightTwo mother ship, lit its engine and appeared to explode. Pieces of the space plane then began to rain down all over the desert.

The motor had exploded. Or the nitrous oxide tank had burst. At least that’s what I and two photographers – whose pictures of the accident would soon be seen around the world – thought had occurred as we watched the flight from Jawbone Station about 20 miles north of Mojave.

We really believed we had seen and heard a blast nine miles overhead, the photos appeared to show one, and it was the most plausible explanation at the time.

We were wrong. More than two days after the accident, the National Transportation Safety Board (NTSB) revealed that co-pilot Mike Alsbury had prematurely unlocked SpaceShipTwo’s feather system during powered ascent. The ship hadn’t blown up, it had broken up as the twin tail booms reconfigured the vehicle with the engine still burning at full thrust.

In his new book, Richard Branson recounts that on the morning of Oct. 31, 2014, he was on his private Caribbean island in a state of “schoolboy excitement.” The reason? Three time zones away in California’s Mojave Desert, Virgin Galactic and Scaled Composites were conducting the longest and most ambitious flight test of the SpaceShipTwo suborbital tourism vehicle.

One day in mid-2003, Virgin Atlantic pilot Alex Tai wandered into a hangar at Mojave Airport and discovered SpaceShipOne, a  suborbital rocket plane that Scaled Composites’ Founder Burt Rutan was secretly building to win the $10 million Ansari X Prize for the first privately-built crewed vehicle to reach space twice in two weeks.

The chance discovery would eventually solve separate problems the famed aircraft designer and Tai’s boss, Richard Branson, were trying to solve. Rutan’s spaceship was being funded by Microsoft billionaire Paul Allen, who wanted to win the prize but had no plans to finance a commercial follow-on spacecraft.

Four years earlier, Branson had registered a new company named Virgin Galactic Airways and set off in search of someone to build a vehicle capable of carrying passengers into space. Those efforts had come to naught until Tai made his discovery at the dusty airport in California’s High Desert.

MOJAVE, Calif. (Scaled Composites PR) — This past weekend, the Scaled test team successfully executed a low speed taxi test of the Stratolaunch aircraft. During this initial taxi test, the aircraft moved down the runway under its own power for the first time. These first test points have demonstrated the fundamental ability to control the aircraft speed and direction on the runway.

The morning of Dec. 3, 2016, began like so many others in Mojave. The first rays of dawn gave way to a brilliant sunrise that revealed a cloudless, clear blue sky over California’s High Desert.

This was hardly newsworthy. For most of the year, Mojave doesn’t really have weather, just temperatures and wind speeds. It had been literally freezing overnight; the mercury was at a nippy 28º F (-2.2º C) at 4 a.m. As for Mojave’s famous winds – an enemy of roofs, trees and big rigs, but the lifeblood of thousands of wind turbines that cover the landscape west of town – there really weren’t any. It was basically a flat calm.

In other words, it was a perfect day to fly.

Pete Siebold and Mike Alsbury heard the sound of hooks disengaging and felt a sharp jolt as SpaceShipTwo was released from its WhiteKnightTwo mother ship. Relieved of a giant weight, WhiteKnightTwo shot upward as the spacecraft plunged toward the desert floor.

“Fire,” Siebold said as the shadow of one of WhiteKnightTwo’s wings passed across the cabin.

“Arm,” Alsbury responded. “Fire.”

The pilots were pushed back into their seats as SpaceShipTwo’s nylon-nitrous oxide hybrid engine ignited behind them, sending the ship soaring skyward on a pillar of flames.

Checking my messages on Wednesday at LAX after a long flight from back east, I was startled to learn that Paul Allen’s ginormous Stratolaunch aircraft had been rolled out of its hangar for the first time in Mojave while I was in transit.

I had been expecting some official roll-out ceremony later this year ala SpaceShipTwo where the press and public could get a good look at the twin fuselage, WhiteKnightTwo-on-steroids air-launch platform.

SpaceShipTwo Flight Test Scheduled for this Morning

Word has it that Virgin Galactic has scheduled the fourth glide flight of SpaceShipTwo Unity this morning in Mojave. The test will be the first for Richard Branson’s suborbital space plane in more than two months.

Cell service permitting,  I will be providing coverage of the test at www.twitter.com/spacecom

On the test card for today is deployment of the new spaceship’s redesigned feather system, which re-configures the ship when it returns from space. Unity will be hauled aloft to an altitude of about 50,000 feet by the WhiteKnightTwo carrier aircraft Eve.

The premature deployment of the feather system during powered ascent led to the destruction of the first SpaceShipTwo Enterprise during a flight test on Oct. 31, 2014. Scaled Composites pilot Mike Alsbury died in the accident. Virgin Galactic has added a mechanism to the feather system to prevent premature deployment of the feather.

The weather forecast looks good for the flight, with sunny skies and low surface wind speeds.

There’s a NOTAM (Notice to Airmen) for the operation of an unmanned aerial system (UAS) at the spaceport from 6 a.m. to noon. It’s not clear who will be operating the system, but it wouldn’t surprise me if Virgin Galactic is aiming to capture video of the flight from the air.

The six-hour period for UAS operations overlaps with the likely window for a SpaceShipTwo flight test. So, it is unlikely that this is a coincidence.

Branson Still Doesn’t Really Understand Why SpaceShipTwo Crashed

Virgin Galactic Founder Richard Branson was interviewed for the Jan. 30 edition of NPR’s “How I Built This” podcast. Beginning at 25:44, there’s a brief discussion of the October 2014 crash that destroyed the first SpaceShipTwo and killed co-pilot Mike Alsbury.

Branson recalls that for the first 12 hours after the accident he wasn’t sure if the SpaceShipTwo program would continue. “But, once we realized it was a pilot error and not a technical error, I was able to tell all the engineers it was nothing to do with them. And that the basic craft was sound.”

Alas, most of this explanation is wrong.
