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.

The competition heats up: Russia considers building a heavy-lift rocket, even as it completes the design and construction of its new Angara commercial rocket family.

The headline of the article focuses on the heavy-lift rocket, but the meat of the article is its details on Angara, which is expected to make its first launch in 2014.

NASA and one of its major IT contractors have both screwed up badly, according to a new Inspector General report.

7:32 pm

It ain’t just the Obamacare website: NASA and one of its major IT contractors have both screwed up badly, according to a new inspector general report.

According to [the inspector general], NASA and HP Enterprise Services have encountered significant problems implementing the $2.5 billion Agency Consolidated End-User Services (ACES) contract, which provides desktops, laptops, computer equipment and end-user services such as help desk and data backup. Those problems include “a failed effort to replace most NASA employees’ computers within the first six months and low customer satisfaction.”

But don’t worry. NASA’s management, the same management that is building the James Webb Space Telescope and the Space Launch System, is right on the case.

Congress hovers over commercial space like a vulture

9:34 am

We’re here to help you: A House subcommittee held hearings yesterday to consider updating the Commercial Space Launch Act that regulates the commercial space tourism industry.

Forgive me if I am pessimistic about anything Congress might do. So far, every time they have updated the law Congress has increased the regulatory regimen, making it harder and more expensive for these companies to get started. Consider these words from Donna Edwards (D-Maryland), the ranking Democrat on the subcommittee:

A new harvest of vegetables in space!

A new harvest of vegetables in space!

Notice that this research is a partnership of the Russians and an American university. NASA is not included. When I wrote about this subject for Air & Space a few years ago, the American researcher explained that there was too much bureaucracy working with NASA. Moreover, the Russians were much more knowledgeable about crop research in space, as they had been doing it for decades already on their Salyut and Mir stations.

What life has been like for one engineer who works at SpaceX.

What life has been like for one engineer who works at SpaceX.

Key quote:

According to Pearce, the best and the worst things about working for Musk are actually the same. “He doesn’t feel the need to make reasonable requests,” Pearce says. “The whole idea of SpaceX is not reasonable. The idea that a dot-com millionaire could take [US] $100 million and start a rocket company that within 13 years would be taking supplies to the International Space Station, that’s on track to take crew to the International Space Station — that’s not reasonable.”

But SpaceX did it.

In celebration of the tenth anniversary of Opportunity’s landing on Mars, the journal Science publishes a special section of the newest findings from Mars.

In celebration of the tenth anniversary of Opportunity’s landing on Mars, the journal Science has published a special section of the newest findings from Mars.

The main conclusion of all this research is that Mars was once potentially habitable, though there is no evidence so far to show that anything actually inhabited it. The data obtained however is now giving scientists clues on the best places to look for the remains of that ancient life, should it exist.

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

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.

Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.

3:57 pm

Because of a computer reboot, Rosetta’s revival from hibernation came 18 minutes late.

[Rosetta] woke yesterday as planned, to the relief of ESA scientists – but the signal it sent home to confirm it was awake reached Earth late, fraying the nerves of some mission controllers in the meantime. Due to call at 1745 GMT, Rosetta did not announce its revival until 1818. Fifteen minutes could be explained because the spacecraft’s computer checked the on-board clock only every quarter of an hour. The additional 18 minutes, however, was a mystery.

Now, the telemetry has shown that soon after Rosetta’s first revival sequence had started, the on-board computer automatically rebooted and the sequence started again, causing 18 minutes of delay.

It seems all is well now, though the engineers plan to spend some time pinpointing the cause of the reboot.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.

A donut-sized rock suddenly appears in front of the Mars rover Opportunity.

NASA announced the discovery of the rock at an event at Caltech in Pasadena this past Thursday night, dubbing the rock “Pinnacle Island.” “It’s about the size of a jelly doughnut,” NASA Mars Exploration Rover lead scientist Steve Squyres told Discovery News. “It was a total surprise, we were like ‘wait a second, that wasn’t there before, it can’t be right. Oh my god! It wasn’t there before!’ We were absolutely startled.”

If you want to see the inside of NASA’s gigantic Vehicle Assembly Building (VAB), you better hurry. Tours cease in February.

If you want to see the inside of NASA’s gigantic Vehicle Assembly Building (VAB), you better hurry. Tours cease in February.

Tours into the VAB have only occurred during gaps in the American space effort. I was lucky to visit Florida back in 1977, after the end of the Apollo program and before the start of the shuttle program, so my tour went inside the VAB. For the last few years, since the shuttle’s retirement, interior tours resumed.

The tour is worth it. If you can find the time and money, get down there now!

The European Space Agency has now released its first cost estimates for upgrading and replacing its Ariane 5 rocket.

The European Space Agency has now released its first cost estimates for upgrading and replacing its Ariane 5 rocket.

Europe needs to find about 1 billion euros ($1.35 billion) to complete development of an upgrade to its current Ariane 5 heavy-lift rocket, which would fly in 2018 and be capable of lifting satellites weighing 11,000 kilograms into geostationary transfer orbit, European Space Agency Director General Jean-Jacques Dordain said Jan. 17. The Ariane 5 upgrade, called Ariane 5 ME, will be on the table for ESA governments to decide, alongside the new Ariane 6 rocket, at a meeting scheduled for December in Luxembourg.

In a press briefing in Paris, Dordain said it is too early to say how much Ariane 6 will cost to develop. Government and industry estimates have ranged between 3 billion and 4 billion euros, with an inaugural flight in 2021.

As Doug Messier notes in his worthwhile analysis of these numbers, “Europe is in deep trouble.” From a customer’s perspective, these new rockets won’t fly (pun intended). The cost is too high and the development time too long. By the time they get both Ariane 5 and Ariane 6 ready for launch they will be obsolete and overpriced, when compared to the rocket’s that will already be available from their competitors.

Scaled Composites did an engine test today in Mojave of an alternative engine for SpaceShipTwo.

The competition heats up: Scaled Composites did an engine test today in Mojave of an alternative engine for SpaceShipTwo.

In this case, the company is even competing with itself, in that its first engine design is now in competition with another engine design. Considering the rumors about problems with that first design, I suspect the new design is probably winning.
