A detailed update on the status of spacesuit repairs on ISS, following the July water leak during a spacewalk.

After additional tools and parts were sent up on both Progress and Cygnus freighters, astronauts on ISS pinpointed the problem and replaced the failed the “fan/pump/separator”. The faulty unit was brought back to Earth for further analysis in the manned Soyuz craft yesterday.

Of the four U.S. spacesuits on ISS, one is still considered faulty and needs to be replaced, which will happen with the next Dragon flight expected sometime in February 2014.

During a five hour EVA that had lots of difficulties, two Russian cosmonauts took the Olympic torch on a spacewalk

During a five hour EVA yesterday that had lots of minor technical difficulties, two Russian cosmonauts took the Olympic torch on a spacewalk.

Most of the press is focusing on the PR stunt with the Olympic torch, but I think these issues are more interesting:

Working around the Service Module, Kotov and Ryazanski worked on cables at the RK21 site before attempting to fold up the panels on the hardware into its original configuration. The EVA tasks were mainly related to the preparations on the Urthecast pointing platform for installation of the HD camera in December. However, only the removal of the launch restraint from VRM EVA workstation and the disconnection of the RK-21 experiment were completed. The duo struggled with the relocation of the Yakor foot restraint – which they opted to take back to the airlock instead – while also failing to fold and lock RK-21 experiment antenna panels. While the spacewalkers managed to take a large quantity of photos for engineers on the ground to examine, the spacewalk was concluded after the failure to fold up the RK-21 panels, resulting in outstanding tasks for the next EVA.

The investigation into the spacesuit leak in July is now awaiting the return of equipment from ISS.

The investigation into the spacesuit leak in July is now awaiting the return of equipment from ISS.

The station astronauts removed a cooling system pump and small contaminants found in the garment’s Primary Life Support System plumbing. The old fan pump separator and the preserved contaminants, including a 1-cm. piece of plastic, will return to Earth aboard Russia’s TMA-09M crew transport late Nov. 10 with Parmitano, NASA astronaut Karen Nyberg and ISS Russian commander Fyodor Yurchikhin. The hardware and contaminants will then be flown by NASA transport from the Kazakh landing site to Johnson Space Center, where a Mishap Investigation Board (MIB) hopes to quickly complete its probe of the worrisome incident.

Though it appears they have narrowed the problem to a small number of components, the need to return these components to Earth illustrates an overall design flaw with the space spacesuit. When the shuttle was flying regularly these components were easy to return to Earth, which is why NASA designed its suit for maintenance on the ground. Now that the shuttle is gone, however, it is difficult to get components returned, which makes spacesuit maintenance difficult if not impossible.

Spacesuits need to be repairable in space. If you are orbiting Mars and one fails, you can’t call in a repairman from Earth to fix it.

Chris Hatfield describes how a bureaucratic tangle with the space doctor bureaucracy almost grounded him before his ISS expedition.

Bureaucracy in space: In a new book, astronaut Chris Hatfield describes how a bureaucratic tangle with the space doctor bureaucracy almost grounded him before his ISS expedition.

β€œThe secrecy and paternalism really bothered me. They trusted me at the helm of the world’s space ship, but had been making decisions about my body as though I were a lab rat who didn’t merit consultation.” The β€œthey” Hadfield refers to are members of the Multilateral Space Medicine Board (MSMB), a body of representatives from the U.S., Canada, Europe, Japan and Russia who judge the medical fitness of astronauts to go on missions. ….

The bureaucracy wanted Hatfield to undergo an emergency operation to make sure everything was okay. He refused,

triggering what Hadfield describes as a β€œKafkaesque” journey through β€œa bureaucratic quagmire where logic and data simply didn’t count.” … “Internal politics and uninformed opinions were what matΒ­tered,” he says in the book. β€œDoctors who hadn’t ever performed a laparoscopic proceΒ­dure were weighing in; people were making decisions about medical risks as though far greater risks to the space program itself were irrelevant.”

I find this interesting in that, of the astronauts I have interviewed over the years, I can’t remember any who had good words to say about the official government doctors they had to deal with, both in the U.S. and in Russia.

Except for a troublesome fan, the first Cygnus cargo capsule to dock with ISS is performing perfectly.

Except for a troublesome fan, the first Cygnus cargo capsule to dock with ISS is performing perfectly.

The fan has been a minor issue. The astronauts have simply turned it off periodically when it started to act up. What is really important is this:

The next Cygnus – along with its Antares launch vehicle – is already being processed at Orbital’s Wallops facility, with a target launch date of December 15, with an available launch window through to December 21.

An eleven year old’s experiment in brewing beer in space will fly to ISS on the next Cygnus cargo flight in December.

An eleven year old’s experiment in brewing beer in space will fly to ISS on the next Cygnus cargo flight in December.

The tiny brewery is set up inside a 6-inch-long (15 centimeters) tube, filled with separated hops, water, yeast and malted barley β€” all of the key ingredients used to make beer β€” and will be delivered to the station by the commercial firm NanoRacks. An astronaut aboard the station will shake up the mixture to see how the yeast interacts with the other ingredients in the beer. “I really didn’t expect this from the start,” Bodzianowski told KDVR, a Fox affiliate in Denver. “I really just designed my experiment to get a good grade in my class.”
