Virgin Galactic’s WhiteKnightTwo mother ship unveiled after major overhaul

9:15 am

Virgin Galactic yesterday rolled its WhiteKnightTwo mother ship from its hanger after a 15-month overhaul in preparation for taxi and flight tests.

After some initial taxi and flight tests in Mojave in California, the plane will fly to New Mexico for further flight tests with Unity attached. Company officials hope to complete these test flights by the end of March, and then begin commercial flights shortly thereafter.

In comparing the pictures released yesterday at the link above with this 2009 picture, it appears the company completely replaced the central bar that connects the plane’s two passenger sections. In the older picture, that bar was not straight, but was built like a very shallow upside-down “V”, with the center point where a SpaceShipTwo spacecraft was attached.

The new bar is straight, and appears more robust.

Virgin Galactic is replacing its WhiteKnightTwo mother ship

9:21 am

Virgin Galactic yesterday announced that it has hired Aurora, a Boeing subsidiary, to build two new mother ships to to replace WhiteKnightTwo and launch its SpaceShipTwo suborbital space planes.

Virgin Galactic Chief Executive Officer Michael Colglazier said: “Our next generation motherships are integral to scaling our operations. They will be faster to produce, easier to maintain and will allow us to fly substantially more missions each year. Supported by the scale and strength of Boeing, Aurora is the ideal manufacturing partner for us as we build our fleet to support 400 flights per year at Spaceport America.” [emphasis mine]

The press release claims the first new mother ship will begin operations in 2025.

Forgive me if I am very very skeptical. The highlighted words tell us a lot about this company. First, we now have confirmation that the company has had problems maintaining WhiteKnightTwo. This fact was strongly implied when all planned flights in ’21 and ’22 were cancelled following that first passenger flight in July ’21 in order to do a full maintenance refit of WhiteKnightTwo. This press release tells us that the company’s management has recognized that WhiteKnightTwo cannot be maintained much longer.

Second, the company continues to overhype its future, even without Richard Branson. The chances of it flying 400 times per year, anytime in the near future, is so slim as to be non-existent.

Third, the need to hire an outside company to build these new mother ships also suggests that Virgin Galactic no longer has the capability of doing it itself.

Right now the company’s stock is selling for about $7 per share, well below its initial price of about $12. Expect it to fall again.

Virgin Galactic reveals issue with WhiteKnightTwo

9:43 am

Capitalism in space: On the same day that Virgin Galactic unveiled a $130 million loss in its first quarter report, it also announced that it might have to delay the next flight of its Unity suborbital spacecraft because of an undisclosed “wear-and-tear issue” on its carrier airplane.

From the second link:

[Mike Moses, president of space missions and safety], in response to later questions from analysts, did not disclose the specific component of the aircraft that was at the heart of the issue, but described it as a “family of items that relate to fatigue and long-term stress” of the airplane. It was not an issue with the number of flights of VMS Eve, which first flew in 2008 and has made fewer than 300 flights since.

Engineers are currently examining the plane to determine if additional maintenance is needed now to correct that problem, with an update expected next week. Virgin Galactic had planned to perform work on the plane this fall during a downtime that would also include work on VSS Unity, but Moses said engineers are now looking at whether some of that work needs to be moved up.

If maintenance is needed now, it would delay the schedule of flight tests for SpaceShipTwo, but Moses said it was “a little too early” to know how long that would be.

They had previously announced that the next flight would be in May. They will decide in the next week whether to delay it.

Meanwhile, the company’s stock price continues to tumble, dropping from a high of about $62 earlier this year to a low of about $14 today. And I would say that the price is still over-priced. The path to profit for Virgin Galactic has become extremely narrow, with few options and not much margin, especially with Blue Origin now only two months away from its first commercial suborbital tourist flight.

Richard Branson started Virgin Galactic shortly after the SpaceShipOne won the Ansari X-Prize in 2004, promising hundreds of commercial passenger flights per year in only a few years. Seventeen years later no such flights have ever occurred. Worse, not only will Blue Origin likely do the first commercial suborbital flight first, SpaceX and Axiom are likely to complete the first orbital tourism flights before Virgin Galactic.

No harm to Branson however. He has sold off most of his stock in the company, and did it when its price was still high.

In an effort to reassure its ticketholders, Virgin Galactic sent them email on May 10 disputing the story that they have discovered cracks in WhiteKnightTwo.

In an effort to reassure its ticketholders, Virgin Galactic sent them an email on May 10 disputing the article that said there are cracks in WhiteKnightTwo’s wings.

The email was interestingly sent before the article was published, which of course meant that it could not directly address any of its findings.

The story above also has a link to an article detailing the many predictions by Virgin Galactic about when they will begin commercial flights, going back to 1999. To put it mildly, their track record has not been good.

Is it cracked or not? On Tuesday Virgin Galactic rolled WhiteKnightTwo out of its hanger “as part of a gearing up process.”.

Though the above article is very vague about what is being done, this article explains that they are doing taxi tests of new landing gear. The timing, however, makes me suspect that this is also a public relations ploy to counter yesterday’s reports about cracks in the vehicle’s wings.

A news story today reports that cracks have been discovered in the wings of WhiteKnightTwo.

More problems for Virgin Galactic: A news story today reports that cracks have been discovered in the wings of WhiteKnightTwo.

Sources tell me the cracks are along the spars that run the length of the wings. Specifically, they are located where the spars connect with the fuselage. My sources tell me the cracks have caused quite a bit of concern among the engineers at Virgin and Scaled. One particularly worrisome aspect is that nobody knows why or when they occurred.

I’m told there is some comfort in the repairs being made based on previous Scaled experience in patching composites. However, since the cause of the cracks is uncertain and WhiteKnightTwo is unique in terms of its size and the stresses placed on it by SpaceShipTwo, the engineers are in uncharted territory. They don’t know if they have addressed the root cause, or whether the problem will reoccur.

If this story turns out to be trie, it will likely be a disaster for Virgin Galactic. Not only can they not yet fly SpaceShipTwo because of engine issues, the mother ship that puts the spacecraft into the air can’t fly either.

From Virgin Galactic come two announcements today

8:59 am

The competition heats up: From Virgin Galactic come two announcements today:

The second is really the big news, especially as it appears they already have some customers.

LauncherOne will be a two-stage vehicle capable of carrying up to 500 pounds (225 kilograms) to orbit for prices below $10 million. The rocket will be launched from Virgin Galactic’s proven WhiteKnightTwo, the uniquely capable aircraft also designed to carry SpaceShipTwo aloft to begin her suborbital missions. Thanks to the extreme flexibility of air launch, Virgin Galactic’s customers will enjoy reduced infrastructure costs in addition to the wide range of possible launch locations tailored to individual mission requirements and weather conditions. Branson and other senior executives announced that work has already begun on the vehicle.

The competition heats up: SpaceShipTwo was in the air on Friday, as WhiteKnightTwo did a 1.5 hour test flight with the ship attached to its belly.

This was the second flight of WhiteKnightTwo in three days, and is in line with Virgin Galactic’s test flight schedule announced in May. If the test flights go well, expect that first rocket-powered flight of SpaceShipTwo later this year.

Test flights of SpaceShipTwo resume

9:22 am

After a summer break, the flight tests of SpaceShipTwo have resumed. Thursday’s test appeared to a bit more exciting that previous flights:

Test card called for releasing the Spaceship from WhiteKnightTwo and immediately entering a rapid descent. Upon release, the Spaceship experienced a downward pitch rate that caused a stall of the tails. The crew followed procedure, selecting the feather mode to revert to a benign condition. The crew then defeathered and had a nominal return to base. Great flying by the team and good demo of feather system.

SpaceShipTwo’s First “Feathered” Flight

2:15 pm

SpaceShipTwo’s has successfully completed its first “feathered” flight.

After a 45 minute climb to the desired altitude of 51,500 feet, SpaceShip2 (SS2) was released cleanly from VMS Eve [WhiteKnightTwo] and established a stable glide profile before deploying, for the first time, its re-entry or “feathered” configuration by rotating the tail section of the vehicle upwards to a 65 degree angle to the fuselage. It remained in this configuration with the vehicle’s body at a level pitch for approximately 1 minute and 15 seconds whilst descending, almost vertically, at around 15,500 feet per minute, slowed by the powerful shuttlecock-like drag created by the raised tail section. At around 33,500 feet the pilots reconfigured the spaceship to its normal glide mode and executed a smooth runway touch down, approximately 11 minutes and 5 seconds after its release from VMS Eve.
