Sources in Russia indicated today that the contract for Sarah Brightman’s space tourist flight has not yet been signed.

Brightman will have turned 55 by that time, which means she will become one of the 20 oldest cosmonauts of the world, among which there is now only one woman (Barbara Morgan, which made a shuttle flight in 2007). “It is not known how the next three years, which the singer will spend in permanent travel around the world, will affect her health,” the source said. It is most likely that only Russian cosmonauts will take part in the 2015 ISS mission, who will take all three spaces in the Soyuz, he said.

The story focuses on the publicity gained for Brightman by making her announcement, but the actual scoop, assuming the source is correct, is that she doesn’t have a contract.

“Long-term budget pressures on NASA mount.”

12:07 pm

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.

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.

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.

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.

A spacewalk November 1 will attempt to find and repair a coolant leak that could force a power reduction at the station.

Construction workers in space: A spacewalk November 1 will attempt to find and repair a coolant leak that could force a power reduction at the station.

A slight 1.5-pound-per-year leak in the channel 2B cooling system has been present since 2007 and during a shuttle visit last year, two spacewalking astronauts added eight pounds of ammonia to the reservoir to boost it back up to a full 55 pounds. The plan at that time was to top off the system every four years or so to “feed the leak,” replacing the lost ammonia as required.

But over the past few months, engineers saw the leak rate suddenly quadruple, either because something changed at the original leak site or, more likely, because another leak developed somewhere else in the system.

Whether the leakage was caused by space debris or a component failure of some sort is not yet known. But the result is: If the leak continues at its current rate, the coolant will drop below a 40-pound safety limit and the system will shut down by the end of the year or shortly thereafter, taking power channel 2B down with it. While the space station can operate without the full complement of power channels, the loss of channel 2B would force flight controllers to power down equipment, eliminating redundancy and reducing the amount of research the crews could carry out.

Orbital Sciences has delayed the first demo launch of its Cygnus cargo capsule until March 2013 at the earliest.

Orbital Sciences has delayed the first demo launch of its Cygnus cargo capsule until March 2013 at the earliest.

The schedule for Antares itself has not been delayed. Launchpad tests are still scheduled to begin next week, with the first engine test set for early November, and the first launch of Antares set for December.

They don’t explain the reason for the Cygnus delay. I suspect they simply decided to be realistic. It was always unlikely that the first Cygnus launch would follow only a month after the first Antares launch, especially if there are any kinks in that launch.

One engine of the Falcon 9 failed during launch.

8:43 am

Confirmed: One engine of the Falcon 9 exploded during launch.

Video at the link. The other 8 engines picked up the slack — as designed — and got Dragon into orbit.

This spectacular engine failure will of course have to be reviewed. However, if I were a commercial satellite company looking for a rocket to get my satellites into orbit, this failure would be recommendation, not a deterrent. The Falcon 9 demonstrated that even if one engine fails (and this one did by blowing up!), the rocket can survive the failure and make it to orbit. If that isn’t clear proof that this is a well designed and well built rocket, nothing is.

NASA and the Russians have agreed to fly a two-person year long mission on ISS beginning in the spring of 2015.

It’s now official: NASA and the Russians have agreed to fly a two-person year long mission on ISS beginning in the spring of 2015.

NASA has denied that this agreement has any connection with the Sarah Brightman/Russian deal, but I still wonder. Either way, it is very good news. Not only will they finally be using ISS appropriately, a mission like this will generate some real excitement for space exploration that the repeated boring six month expeditions to ISS have failed to do. Even better would be to schedule a two year mission, simulating a journey to and from Mars.

In order to get a seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out and thus forcing the U.S. agency to finally agree to a year long mission.

7:12 pm

Irony of ironies: In order to buy her seat on a Soyuz capsule Sarah Brightman outbid NASA, bumping its astronaut out.

This was a win-win for the Russians. They get paid more by Brightman than by NASA (over $51 million), and they finally get that year long mission they’ve been campaigning for for years. Because Brightman has taken one of NASA’s seats, the U.S. agency was forced to agree to the extended mission in order to maintain a presence on the station throughout that time period. Otherwise, their astronaut would come home and be replaced by Brightman, but for only ten days.
