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.

Though they really don’t need it, a private effort to reactivate a 1970s spacecraft has now gotten NASA’s okay.

Though they really don’t need it, a private effort to reactivate a 1970s spacecraft has now gotten NASA’s okay.

This piece of paper from NASA is a definite nice-to-have, given that “a private entity cannot legally salvage U.S. government property in space,” according to Mike Gold, a space law expert and attorney who works full time as the head of Washington operations for Bigelow Aerospace, the North Las Vegas, Nevada, company developing inflatable space habitats with technology licensed from NASA.

But practically speaking, it appears NASA could have done little to stop the ISEE-3 Reboot project from moving ahead with its plan to take over the old spacecraft — an Earth-Sun observatory that launched to the gravitationally stable Earth-Sun Lagrange point 1 in 1978 and is now swinging back toward the home planet in the heliocentric orbit NASA nudged it into in 1982 to chase comets.

What is really more important is that their effort to raise the necessary private funds for this project has largely succeeded.

Russia fights back

9:50 am

Much has been made about the sanctions the Obama administration has imposed on any cooperation with Russia due to the situation in Ukraine and how those sanctions might damage the commercial and manned space efforts of the United States.

So far, all evidence has suggested that the sanctions have little teeth. The Obama administration exempted ISS from the sanctions. It also appears to be allowing the shipment of all commercial satellites to Russia for launch. Even a court injunction against using Russia rocket engines in U.S. military launches was lifted when the Obama administration asked the judge to do so.

The Russians now have responded. Why do I take their response more seriously?

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.

Does the auction sale of an Excalibur Almaz capsule signal the end of this manned space commercial company?

Does the auction sale of an Excalibur Almaz capsule signal the end of this manned space commercial company?

It certainly looks that way, which is tragic in that the company had a very smart and viable idea: Use already built Soviet-era manned space equipment to launch a space hotel and provide a ferry to it for a relatively low cost. The development was already done and the hardware already built. All they had to do is refurbish and update things.

Ground tests of SpaceShipTwo’s engines continue.

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.

Building a scale model of the International Space Station — using matchsticks!

Building a scale model of the International Space Station — using matchsticks!

Recently completed by Acton, the wooden ISS is as impressive in size as it is in detail. Comprised of 282,000 matchsticks, the 1/26 scale model required 8 gal (30 L) of glue and took roughly 1,950 hours to complete. Whereas the actual ISS measures out at 108.5 m (356 ft) wide and 72.8 m (239 ft) long, Acton’s scaled down version measures out at an impressive 4.1 m (13.5 ft) and 2.8 m (9.2 ft) wide. Solar arrays, trusses, communication components, and even the Space Shuttle Atlantis, are all there in intricate detail.

With pictures.

Fact checking Elon Musk’s statements about his company’s efforts to reuse the Falcon 9 first stage reminds us of some space history and one of Musk’s chief competitors.

Fact checking Elon Musk’s statements about his company’s efforts to reuse the Falcon 9 first stage reminds us of some space history and one of Musk’s chief competitors.

The bottom line: Bringing the first stage back to Earth safely and vertically is doable, and has been done before.

How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.

How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.

A very interesting read, as it outlines the specific technical problems faced by engineers that one wouldn’t normally consider. The capsule has to be able to remain functional and reliable after months in orbit, but it also has to become functional at a moment’s notice, should an emergency happen.
