Some more details have been revealed about Bigelow’s deal with NASA to send one of its modules to ISS.
Some more details have been revealed about Bigelow’s deal with NASA to send one of its modules to ISS.
This is apparently going to be another test of a smaller prototype, similar to Bigelow’s Genesis I and Genesis II modules already in orbit, but this time docked to a manned station.
What is interesting however about this article above is that reveals the names of the seven countries that have signed an agreement with Bigelow for future use of the company’s orbiting stations:
In another interesting development, Bigelow has named the seven sovereign customers who’ve expressed interest in leasing space aboard a future Bigelow commercial space station. Bigelow has preliminary agreements with the United Kingdom, the Netherlands, Australia, Singapore, Japan, Sweden and the United Arab Emirate of Dubai, according to Reuters. According to another report by Leonard David, Bigelow expects to have two BA 330 modules ready for construction of Space Station Alpha by late 2016. The Bigelow 330 is a much larger module, weighing 43,000 pounds with a diameter of 22 feet and length of 31 feet.
Bigelow Aerospace previously announced that it plans to charge sovereign customers $23 million for a 30-day stay aboard a Bigelow space station. That price includes space transportation, astronaut training, and consumables.

How the Bigelow module added to ISS will change the space equation.
How the Bigelow module added to ISS will change the space equation.
Looking a bit further down the road, the potential launch of a Bigelow BEAM module, particularly if it takes place on a SpaceX Falcon 9 booster could be a harbinger of much greater things to come. As Mars visionary Robert Zubrin and many others have observed, the addition of an inflatable module similar to that being considered for the station, to the SpaceX Dragon 2.0 capsule greatly increases the available space and capability of a future Dragon to serve both as a Mars transfer vehicle, and / or surface habitat. Add in the introduction of Falcon Heavy, and the pieces for an alternate vision of far more affordable (and timely) inner system exploration begin to fall into place.
Stewart Money has it exactly right. I have never accepted the claim that Orion was the only spacecraft being built that would be capable of going beyond low earth orbit. Add the right components to any manned vehicle, and you have an interplanetary spaceship.
The trick of course is adding the right components. For both Orion and Dragon, the present assumptions are much too nonchalant about what those components are. For humans to prosper on an interplanetary mission, the vessel requires a lot more than a mere capsule and single module.

The demo mission of robotic refueling of satellites on ISS goes forward this month.
Robot refueling of satellites: The demo mission on ISS goes forward this month.
As much as I celebrate this work, conceived and designed by engineers at the Goddard Space Flight Center (the same people who ran the missions that maintained the Hubble Space Telescope), I worry that nothing will come of it. The demo mission itself is designed to duplicate exactly the refueling of several climate satellites already in orbit whose lifespans are ending merely because they are running out of fuel. If the ISS demo succeeds, the next natural step would be to plan an actual robotic mission to refuel these satellites.
The worrisome part is that NASA rarely follows through on this kind of research. For example, the agency did tests of an ion engine back in the early 1970s, and it wasn’t until the late 1990s before they finally flew a mission using that technology. Worse, the federal budget situation probably means there is no money to fly such a mission.
Hopefully, some private company will take a look at this engineering, which is all in the public domain, and decide to use it for their own purposes.

NASA used Orbital Sciences’ Taurus 2 rocket for the failed launch of its Glory climate satellite in 2011, even though the agency knew the company had not fixed the problem that caused the loss of the Orbiting Carbon Observatory in 2009.
NASA used Orbital Sciences’ Taurus XL rocket for the failed launch of its Glory climate satellite in 2011, even though the agency knew the company had not fixed the problem that caused the loss of the Orbiting Carbon Observatory in 2009.
The investigators believed there was as much as a 50% chance the faulty component — a fairing separation system for ejecting the protective shroud that covered the satellite during launch — would fail again. Sadly, it did, destroying Glory. More significant for the future, however is this:
Other Orbital vehicles, including the air-launched Pegasus and a new Antares rocket, use a version of the same fairing separation system that is most likely responsible for the combined $700 million loss of two key climate-study satellites. Orbital’s original name for Antares was Taurus II.
So far, NASA has not accepted the Antares shroud-separation configuration for operational flights. Dulles, Va.-based Orbital says it has made a number of changes to its frangible joint fairing separation system in the wake of the Glory launch failure, including modifications to the frangible rail used on Antares. The company is developing that rocket under NASA’s Commercial Orbital Transportation Services (COTS) program to carry cargo to the International Space Station (ISS).
If NASA isn’t satisfied with Orbital’s design changes to this system, it could significantly delay the launch of Cygnus and Antares to ISS.
Update: I had mistakenly referred to the Taurus 2 in the first sentence when the rocket used to launch Glory and OCO was the Taurus XL. This is now corrected.

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