SpaceShipTwo poised for powered test flights

3:51 pm

Virgin Galactic officials outline the status of SpaceShipTwo, suggesting that powered flight tests are finally about to begin.

Providing a rare glimpse of progress on a second spacecraft under assembly at sister organization, The Spaceship Co., Virgin Galactic Vice President of Operations Mike Moses says, “we are ready for space.” A former NASA launch integration manager for the space shuttle, Moses adds that SS2 “has been in modification, getting retrofitted ready to resume powered flights.” He notes that “those are going to start imminently—literally very imminently.”

Commenting on the extensive gap between now and the last rocket flight in January, Moses says, “It might seem a long time since our last powered flight-testing and that maybe nothing has been happening, but [ground testing] has been happening.” Tests have largely focused on ground-firings of a hybrid rocket motor fueled with polyamide-based plastic in place of the hydroxyl-terminated polybutadiene, a form of rubber used for the first series of powered tests. Although this fuel had been used successfully in SpaceShipOne, the vehicle developer Scaled Composites and Virgin Galactic encountered fuel-burn stability and power issues as they tried to scale the Sierra Nevada Corp.-provided hybrid motor up to the size required by the larger SS2.

It appears my guess was right and that the last two glide tests were to retrofit SpaceShipTwo for the new fuel and engine. This has now been accomplished, and they are preparing to begin powered flight tests.

The article also describes work on a second SpaceShipTwo, which when completed will give Virgin Galactic the beginnings of a fleet of ships.

Another delay at Virgin Galactic

2:21 pm

In an interview with David Letterman this week, Richard Branson admitted that his first flight on SpaceShipTwo will not be in December 2014 but early next year.

Watch the interview at the link. It is very clear that Branson is getting uncomfortable with the situation. He has made these claims too many times without showing any results. Also note the incredible ignorance exhibited by Letterman. A good interviewer has to ask some basic questions, but a good interviewer also needs to have a basic understanding of the subject. Letterman shows us here that he doesn’t know squat.

Branson insists he will fly this year

8:54 am

In an interview for USA Today Richard Branson once again repeated his expectation that he will fly in space on SpaceShipTwo before the end of the year.

It sounds like they plan three test flights with their new engine, followed by Branson’s public relations stunt. Even if this plan happens, however, I do not see them ready to fly paying passengers, as they will probably need more test flights to make sure the ship and its engine are truly trustworthy.

SpaceShipTwo flies again

9:44 pm

The competition heats up: For the first time in six months SpaceShipTwo completed a test flight today.

The article above is from NBC, which also has a deal with Virgin Galactic to televise the first commercial flight. It is thus in their interest to promote the spacecraft and company. The following two sentences from the article however clearly confirm every rumor we have heard about the ship in the past year, that they needed to replace or completely refit the engine and that the resulting thrust might not be enough to get the ship to 100 kilometers or 62 miles:

In January, SpaceShipTwo blasted off for a powered test and sailed through a follow-up glide flight, but then it went into the shop for rocket refitting. It’s expected to go through a series of glide flights and powered flights that eventually rise beyond the boundary of outer space (50 miles or 100 kilometers in altitude, depending on who’s counting).

Hopefully this test flight indicates that they have installed the new engine and are now beginning flight tests with equipment that will actually get the ship into space.

DARPA awards contracts for XS-1 spaceplane

9:31 am

The competition heats up: DARPA has announced contract awards to three companies for the construction of its experimental XS-1 spaceplane, designed to take off and land like a airplane.

The contracts go to Boeing, Northrop Grumman, and Masten Space Systems, and have them each respectively partnered with Blue Origin, XCOR, and Virgin Galactic. More details on the Boeing contract can be found here.

The description of the XS program is quite exciting:

Great Britain’s proposed suborbital spaceport locations

9:07 am

The competition heats up: More information was released today describing Great Britain’s suggested spaceport locations.

These spaceports are specifically aimed at the suborbital space tourism market, for American companies like Virgin Galactic or XCOR, or for the developing British company Skylon.

It is interesting that 6 of 8 are located in Scotland, which might very well not be part of the United Kingdom after a vote on separation this fall.

Comparing the rocket vs balloon space tourism ride.

8:59 am

The competition heats up: Yahoo today published a 5 point comparison between a ride on Virgin Galactic’s SpaceShipTwo and Worldview’s Voyager balloon.

The winner, Virgin Galactic, but by a nose. As the story notes, Worldview is the better buy. “You can use the money you save for a nice vacation on Earth — where you can make new friends by telling stores about that time you went to space.”

Virgin Galactic and the FAA on Friday reached agreement allowing the company to fly its suborbital flights from Spaceport America in New Mexico.

The competition heats up: Virgin Galactic and the FAA on Friday reached agreement allowing the company to fly its suborbital flights from Spaceport America in New Mexico.

I suspect that Virgin Galactic wants to hurry its debut in New Mexico in order to help quell the doubts that have been building about the company’s future.

Virgin Galactic finally admitted to its engine troubles on Friday.

9:34 am

Virgin Galactic finally admitted to its engine troubles on Friday.

They have dumped the original engine, switching to a different engine design that the rumors have said they have been testing for the past year.

The company press release is here, with commentary here.

Though it is a good thing that the company has finally come clean and made the switch, they probably waited far too long to do it, as the problems with the old engine likely caused several years delay in their schedule, allowing other companies to catch up with them and thus losing the significant technological advantage that they once held.

Virgin Galactic pretty much admits that SpaceShipTwo will fly to only fifty miles altitude, not 62 (100 kilometers).

Virgin Galactic pretty much admits that SpaceShipTwo will fly to only fifty miles altitude, not 62 (100 kilometers).

The admission came in response to the rumors that say the spacecraft will even have trouble reach 50 miles.

Though the company is making a hard PR effort to dispel the negative rumors that are swirling about in the press, the only way they will really succeed at this is to begin actual test flights, something that has not happened, as they have promised repeatedly since the first powered flight last year.

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.

10:29 am

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.

On Tuesday Virgin Galactic rolled WhiteKnightTwo out of its hanger “as part of a gearing up process.”.

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.

8:27 am

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.

Ground tests of SpaceShipTwo’s engines continue.

9:20 am

Ground tests of SpaceShipTwo’s engines continue.

No flight tests have occurred in four months, however, which suggests that they have decided to abandon their first engine design and are now doing these new ground tests to prove the reliability of the new engine before proceeding to flight tests. The lack of flight tests also suggests that Richard Branson’s most recent announcement that he will definitely fly as a passenger this year is most likely hogwash.

Virgin Galactic is close to getting its FAA launch license.

5:19 am

According to the company’s CEO, Virgin Galactic is close to getting its FAA launch license.

The CEO also said that they hope to fly their first suborbital flight this summer after several lower altitude powered flights.

At this point I will believe this when I see it. Virgin Galactic has made promises like this repeatedly for the past three years, none of which have come true. The time has come for them to put up, or shut up, or finally tell us the truth.

Richard Branson today claimed that Virgin Galactic will fly its first space tourists this year.

1:50 am

Did you ever get the feeling of deja-vu? On Monday Richard Branson claimed that Virgin Galactic will fly its first space tourists this year.

I am all for his success, but I must admit I am becoming skeptical. Branson said exactly the same thing in May 2013, except then he was claiming that the first tourist flight would occur before the end of 2013. It didn’t happen.

There are too many rumors about the engine troubles with SpaceShipTwo to allow me to accept Branson’s claims any longer at face value.

Virgin Galactic today announced the successful testing of their own new rocket engine.

9:32 am

The competition heats up: Virgin Galactic today announced the successful testing of their own new rocket engine.

Virgin Galactic, the world’s first commercial spaceline, announced today that it has reached a significant milestone in the testing of a new family of liquid rocket engines for LauncherOne, the company’s small satellite launch vehicle. As part of a rapid development program, Virgin Galactic has now hot-fired both a 3,500 lbf thrust rocket engine and a 47,500 lbf thrust rocket engine, called the “NewtonOne” and “NewtonTwo” respectively. Further, the NewtonOne engine has successfully completed a full-mission duty cycle on the test stand, firing for the five-minute duration expected of the upper stage engine on a typical flight to orbit. These tests are being conducted on two new state-of-the-art test stands that the team designed, assembled and installed internally. [emphasis mine]

Though they say that these engines are for their orbital rocket, not SpaceShipTwo, I find it interesting that their development was in-house, not by Scaled Composites which has so far been building everything for Virgin Galactic. Moreover, note the highlighted words, “rapid development program.” Though you should never be leisurely about this stuff in order to compete, giving this particular title to this engine program suggests they are in a particular hurry to develop it.

Both factoids suggest again that they are not happy with the performance of the hybrid engines Scaled Composites built for them, under their direction, and are now working hard to replace them.
