“Long-term budget pressures on NASA mount.”
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 included three commercial launches in addition to its cargo flights to ISS.
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.”

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.

The Russians have repaired the severed cable that had cut off their communications with ISS and space.
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 discovery of volcanoes on Io
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:

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.

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.

One of the major backers has pulled out of a solar energy power plant plan for Africa and the Middle East.
One of the major backers has pulled out of a solar energy power plant plan for Africa and the Middle East.
“We see our part in Dii as done,” says spokesman Torsten Wolf of Siemens, one of 13 founding partners of the consortium, which is also based in Munich. Siemens also said that it will pull out of the solar-energy business altogether. Its decision was made in response to falling government subsidies for solar energy and a collapse in the price of solar equipment. But to DESERTEC’S critics, Siemens’ exit also adds to doubts about the plan, which is expected to cost hundreds of billions of dollars. “DESERTEC is an ambitious attempt to do everything at once,” says Jenny Chase, an analyst at Bloomberg New Energy Finance in Zurich, Switzerland. “I think it’s something that will be achieved organically, bit by bit, which will probably be cheaper, easier and achieve the same results.” [emphasis mine]
The cited reasons suggest some fundamental problems with this particular project. That Siemens is abandoning the solar energy entirely, citing the lose of government subsidies as one reason, also suggests there is something fundamental wrong with the industry itself.
Then again, it could be just like the new commercial space industry. Some companies are willing to take the risks to make the money even without subsidies, while others are not.

For the second time, a Progress freighter has launched and, after only four orbits, docked with ISS.
For the second time, a Progress freighter has launched and, after only four orbits, docked with ISS.
This was the fourth Progress launched this year, the second to follow an abbreviated four-orbit rendezvous with the space station. Russian flight controllers normally implement two-day rendezvous profiles, but they are perfecting procedures for single-day flights for possible use with manned Soyuz missions to shorten the time crews are forced to spend in the cramped ferry craft.
The Russians have used the leisurely two-day rendezvous path now for almost a half century. So, why are they suddenly trying to shorten the travel time to ISS to six hours? Though there are many good engineering reasons, I also suspect it is because they are now feeling the pressure of competition. The shorter travel time probably lowers their costs at mission control. It also makes using the Soyuz for manned flights more appealing. Dragon for example is presently using the two-day rendezvous path. And Dragon will soon become a direct competitor to Soyuz, when it begins flying humans in the next three to five years.

The first results from Curiosity’s soil samples have come back.
“Much of Mars is covered with dust, and we had an incomplete understanding of its mineralogy,” said David Bish, CheMin co-investigator with Indiana University in Bloomington. “We now know it is mineralogically similar to basaltic material, with significant amounts of feldspar, pyroxene and olivine, which was not unexpected. Roughly half the soil is non-crystalline material, such as volcanic glass or products from weathering of the glass. ”
Bish said, “So far, the materials Curiosity has analyzed are consistent with our initial ideas of the deposits in Gale Crater recording a transition through time from a wet to dry environment. The ancient rocks, such as the conglomerates, suggest flowing water, while the minerals in the younger soil are consistent with limited interaction with water.” [emphasis mine]
These results suggest that there has been very little water on the Martian surface for a very long time. They do not, however, mean that there is no water there now.

It appears that NASA is at the moment unconcerned should the investigation into the Falcon 9 engine failure on October 7 cause a delay in the next Dragon supply mission to ISS.
It appears that NASA is at the moment unconcerned should the investigation into the Falcon 9 engine failure on October 7 cause a delay in the next Dragon supply mission to ISS.
The supply cache delivered to the station in early to mid-2011 by the now-retired space shuttle placed the six-person orbiting science lab on a firm footing well into 2013, according to Mike Suffredini, NASA’s space station program manager. “The launch date itself, in January, is not really critical to the program from a supply standpoint,” Suffredini told an Oct. 26 news briefing. “So we have some flexibility.”
In the short run a delay here would not be critical. A long delay, which is unlikely, would however not be good for operations on the station, and illustrates why it is very important to get the Orbital Sciences’ Cygnus cargo capsule up an running as soon as possible.
