Unity completes third glide test

The competition heats up? Virgin Galactic’s new SpaceShipTwo, Unity, successfully completed its third glide test on February 24.

I must admit that I cannot get excited by this event. Until Virgin Galactic flies this ship with its engines and puts it through a full suborbital flight, I remain completely skeptical about its capabilities.

Unity successfully completes its first glide flight

Virgin Galactic’s second SpaceShipTwo, Unity, yesterday successfully completed its first glide test flight.

SpaceShipTwo, named VSS Unity, and its carrier aircraft, WhiteKnightTwo, took off from the Mojave Air and Space Port in California at about 9:50 a.m. Eastern. The spaceplane separated from WhiteKnightTwo at 10:40 a.m. Eastern, gliding back to a runway landing in Mojave ten minutes later, according to updates provided by the company.

Congratulations to Virgin Galactic. They need to start making these flights quickly and frequently, and they need to ramp up to powered flight, to quash the skepticism that has built up about the company and its effort. More important, they need to do this because, unlike a decade ago, they are no longer the only game in town. They now have some serious competition.

Another captive carry flight test of Virgin Galactic’s Unity

After cancelling a planned first glide test of Virgin Galactic’s Unity spaceship in early November, the company completed a second captive carry flight on November 30.

“As part of our ground and flight testing, we made a few tweaks to the vehicle,” Virgin Galactic tweeted before the Nov. 30 flight. “We’ll test those in a captive carry flight today.” Virgin Galactic has not announced when the next test flight will take place or if it will include a glide test.

They apparently found some issues both from the first captive carry flight as well as ground tests that required them to make some changes to the spaceship and do another captive carry flight.

Virgin Galactic releases Unity test flight program

In a change from the company’s past policy, which made many promises but never revealed their upcoming schedule in any detail, Virgin Galactic today released their planned test schedule for their new Unity spacecraft.

This test will be the first of a sequence of glide test flights. These flights will cumulatively allow us to test and prove the performance of the vehicle in a variety of conditions: both heavy (e.g. simulating the full weight of a load of fuel, oxidizer, and people) and light (with empty tanks) and in between, at a variety of flight path angles and airspeeds, and so forth. This testing of the “corners of the box” is designed to demonstrate how VSS Unity will perform as it returns from space, after the feather system is retracted and the vehicle becomes a glider and lands on the runway like an airplane. In addition, this phase of flight will also demonstrate and test our abort modes – which culminate in a safe glide back to the runway.

Our team of flight test experts has developed a set of requirements for each planned test flight as well as detailing exactly what we need to test in order to be ready to proceed to the next phase of rocket powered flights. We will fly as many flights as we need to in order to achieve all these objectives.

The schedule, quite properly, does not include any dates. In the past the company and Richard Branson, would make many grand promises about when their test program would be completed without providing any details of what they planned to do during that test program. This time, Branson is quiet, they have announced no schedule dates, but have provided good information about the test program itself. This is a very good change.

Virgin Galactic to begin glide tests of Unity

Virgin Galactic will begin the first glide tests of its new SpaceShipTwo, Unity, this week.

Virgin Galactic test pilot CJ Sturckow, speaking at a “Space Stories” event at The Explorers Club here Oct. 29, said the company has scheduled the first glide flight of the vehicle, named VSS Unity, on Nov. 1. That flight would come after a single “captive carry” test flight of the vehicle in September, when the vehicle remained attached to its WhiteKnightTwo carrier aircraft for its entire flight. “It’s ready to fly, and I’m really looking forward to seeing that,” he said of SpaceShipTwo’s upcoming glide flight.

That glide flight will be the first time VSS Unity has flown on its own, and will be the first in a series of glide flights before Virgin Galactic installs a hybrid rocket motor for powered flight tests.

According to the article, the new rocket motor has successfully completed several long duration test firings.

Virgin Galactic is running out of time. Their competition, Blue Origin, appears much closer to flying passengers.

First test captive carry flight for Unity

The competition heats up: Virgin Galactic today completed its first test flight of its new SpaceShipTwo, Unity, flying it mated to WhiteKnightTwo for almost four hours.

Congratulations to Virgin Galactic! Still, it remains to be seen whether they can get this ship tested and capable of commercial flights fast enough to beat their competition, competition that did not exist when they started their business more than a decade ago.

Virgin Galactic unveils new SpaceShipTwo

The competition heats up: On Friday Virgin Galactic unveiled their replacement SpaceShipTwo, dubbed Unity, replacing the first ship destroyed 16 months ago during a failed flight test.

As is typical of Virgin Galactic, they managed to garner a lot of press coverage of this event. To me, it is a big big yawn. I want to see this ship flying, not towed out from a hanger by an SUV with Richard Branson waving to the crowd.

And until they do, I will consider everything Virgin Galactic does at this point to me nothing more than empty public relations bull.
