Real progress: Russia and the U.S. have named the two astronauts who will spend a year in space beginning in 2015.
This mission will also make room for a Russian tourist flight during that same time period.
A Russian Proton rocket, scheduled for launch in late December, is being replaced because of damage sustained during transport from its factory.
This is not the first time this has happened. In 2010 a Soyuz capsule had to be replaced for the same reason. Modern television journalism (if one can call it that) would immediately ask “Is this a trend?” I instead wonder what the details are in both cases, which unfortunately are not available.
Good news: Boeing indicated today that it is considering increasing its investment in its CST-100 manned capsule in order to accelerate its development.
I suspect that, after Boeing in September let leak the idea that they might shelve CST-100 if the space agency didn’t give them more money, NASA management instead told them in no uncertain terms that if they didn’t show a more serious commitment to building CST-100, they might lose the contract altogether.
As a replacement for its discontinued ATV cargo freighter — which paid its share of ISS — Europe has decided to build a service module for the Orion capsule.
This decision occurred at the same time ESA decided to upgrade Ariane 5 rather than replace it. Both decisions, to my mind, were serious mistakes.

Government space marches on! Cracks have been found in the first Orion capsule intended to fly in space.
The cracks were discovered during a proof pressure test the week of Nov. 5. Proof testing, in which a pressure vessel is subject to stresses greater than those it is expected to encounter during routine use, is one of the many preflight tests NASA is performing on Orion to certify the craft is safe for astronauts, agency spokeswoman Rachel Kraft said. “The cracks are in three adjacent, radial ribs of this integrally machined, aluminum bulkhead,” Kraft wrote in an email. “This hardware will be repaired and will not need to be remanufactured.”
In meetings today the European Space Agency (ESA) has decided to upgrade Ariane 5 rather than immediately build a new Ariane 6 rocket.
Normally I would label this story as an example of “the competition heating up.” In this case, however, I don’t see how an upgrade of Ariane 5 can possibly be competitive. The rocket has been so expensive to operate that — even though it has dominated the launch market for years and is very reliable — ESA has had to subsidize its cost. It has never made a profit. I don’t see how they can reconfigure it enough to bring its cost down to compete with Falcon 9. In other words, they are trying to put lipstick on a pig.
Nor is this surprising. Arianespace is a government-run business, operated like a committee with the member nations of ESA all having a say. Under this arrangement, it is difficult if not impossible to get a quick and efficient decision. Moreover, political concerns will often outweigh issues of efficiency and profits.
In the open competitive market of privately-run companies that the launch market is becoming, I am very skeptical this kind of business can survive.
The next flight of the X-37B has been delayed again, with the new launch date set for no earlier than December 11.

Why SLS will surely die: “Long-term budget pressures on NASA mount.”
Whether the cheaper, more efficient, and competitive commercial space program will survive remains unknown. It could be that our brilliant Congress, which wants SLS, will keep that very expensive program alive just long enough to choke the life out of the commercial space program. Then, with the government part of private space dead from lack of support, they will suddenly be faced with the gigantic bill from the NASA-built SLS and will, as they have done repeatedly during the past four decades, blanch at paying the actually construction and launch costs, and will kill that too.
SpaceX’s launch manifest for 2013 includes three commercial launches in addition to its cargo flights to ISS.
All told, it appears that 2013 will a crucial year for SpaceX. They first need to solve the question of that engine failure from their October Falcon 9 launch. Then they need to begin putting into orbit the long list of private satellites that they have contracts for but have held off launching pending the success of the NASA deal. Once they do that, set to begin next year, they will have proven – beyond a shadow of a doubt — that they are for real.
And on that subject, Elon Musk had some thoughts yesterday about his European competitors: “Europe’s rocket has no chance.”
SpaceX’s Falcon is a new entrant to the launcher market. It has so far made only four flights, but it has a backlog already of more than 40 contracted launches. Its quoted price under $60m per flight is proving highly attractive to satellite operators who have to pay substantially more to get on an Ariane. “Not only can we sustain the prices, but the next version of Falcon 9 is actually able to go to a lower price,” warned Mr Musk. “So if Ariane can’t compete with the current Falcon 9, it sure as hell can’t compete with the next one.”

More on why that communications cable was cut at Russian mission control.
It appears that because of routine maintenance of other equipment, the company that controlled the cable was supposed to mark it so that the repair crew would leave it alone. That repair company is now claiming that the marking never happened.
SpaceX’s Grasshopper rocket has made its highest leap yet, almost 20 feet.
This is only a test vehicle for developing the engineering of a reusable rocket that can land vertically.
The Russians have repaired the severed cable that had cut off their communications with ISS and space.
The article notes that this failure was never a critical problem for ISS, pointing out that there was a back up communications route in the U.S., and that the astronauts on board are trained to work independent of the ground. Though both these points are true, what the article doesn’t mention is that much of the American half of ISS has been built to be run from the American mission control. It is not like Mir, which was designed to be as self-sufficient as possible. The result is that though a communications break in Russia is not really critical, a communications break in the U.S. might be.
The accidental cutting of a communications cable has cut off Russia’s mission control from ISS and many of its satellites.
They have rerouted communications to ISS through mission control in Houston, so the station has not been seriously effected by this accident.
On March 8, 1979, as Voyager 1 was speeding away from Jupiter after its historic flyby of the gas giant three days earlier, it looked back at the planet and took some navigational images. Linda Morabito, one of the engineers in charge of using these navigational images to make sure the spacecraft was on its planned course, took one look at the image on the right, an overexposed image of the moon Io, and decided that it had captured something very unusual. On the limb of the moon was this strange shape that at first glance looked like another moon partly hidden behind Io. She and her fellow engineers immediately realized that this was not possible, and that the object was probably a plume coming up from the surface of Io. To their glee, they had taken the first image of an eruption of active volcano on another world!
Today, on the astro-ph preprint website, Morabito has published a minute-by-minute account of that discovery. It makes for fascinating reading, partly because the discovery was so exciting and unique, partly because it illustrated starkly the human nature of science research, and partly because of the amazing circumstances of that discovery. Only one week before, scientists has predicted active volcanism on Io in a paper published in the journal Science. To quote her abstract:

Engineers have switched Mars Odyssey to its backup navigation equipment in order to save the failing primary system.
Got money to invest? SpaceOps is looking for funds to build its private spacecraft modeled after the American Gemini capsule.
The idea is a good one, as the Gemini capsule was quite capable. Getting almost $100 million from crowd-sourcing however is going to be very tough.
The orbital debris from the exploded upper stage of the failed Proton launch in August now totals over 100 pieces.
The competition heats up: China in 2013: another manned flight and an unmanned lunar landing.
The images don’t provide much information, and most of the article is empty speculation. Nonetheless, China is building something.

Sea Launch is considering moving its base of operations out of the United States.
Hm. The timing of this story, right after the election, is intriguing, is it not?
Boeing to cut 30 percent of its management ranks.
This could be good news for the company. If they do this right, they will reduce their costs without hurting their ability to produce. That they made this announcement today, the day after the election, and that the cuts mostly involve their defense work also suggests it is linked to sequestration, despite the company’s denial.
Sierra Nevada is moving its mini-shuttle, Dream Chaser, into its own facility.
This article isn’t really as positive as I’d like. For one, they haven’t even signed the lease for the building. Instead, it appears that the company is using this announcement, and the subsequent media coverage, to pressure the local city council to provide them subsidies. For another, the article mentions that drop tests of Dream Chaser will occur next spring, a significant delay from previous announcements. Both points make things appear far more tenuous than they should be.
The next launch of the X-37B has been delayed again.
Realtime coverage of today’s spacewalk on ISS.
Update: It appears the spacewalk was a success. The astronauts installed a bypass radiator to isolate the radiator where it is believed the coolant leak is located.
