ISS Spacewalk Cut Short 181

Posted by michael from the practice-in-breath-holding-pays-off dept.
RobertB-DC writes "The spacewalk that was intended to replace a balky power supply ended almost before it started, according to Spaceflight Now's Mission Status Center play-by-play. The Russian Orlan spacesuit worn by US astronaut Mike Fincke developed a problem with its oxygen supply (!), forcing both spacewalkers back to the airlock after less than 15 minutes. Mission control and the ISS crew are still debating what to do next."

      There was probably a reason for this during the cold war. While the American media isn't as free as we think it is, they still would have covered something as significant as a rocket launch. Thus if it failed, the Russians could easily find out. However, the Russians were better at keeping their media in check, so if rockets failed, it would be a lot harder for others to know.

        This would probably take Burt a week and $500,000 to develop, but NASA would take a year or two and tens of millions of dollars to do the same thing.

        And if it's too much for one White Knight to handle, maybe they could launch two of them and mate the rocket at altitude.

        • This would be better then sending a Soyuz why?
          • Might be cheaper. Launch costs for SS1 are between $50,000 and $80,000. Soyuz is probably a lot higher.

            And it would give Rutan a chance to show off Tier 2.

            • Yeah, but they'd have to try to mate a standardized airlock module to Scaled's rocket, or develop and certify a new one. Plus a thoroughly-tested maneuvering system to make sure it didn't hit the Station.

              Seems to me it'd be too much trouble for a busted spacesuit.
              • I was thinking more along the lines of an expendable rocket. Maybe even solid fueled. No need to launch a pressurized craft with wings and life support to get two suits up there. I mean, they're not NASA!

                • That doesn't remove the need for an attachment mechanism (airlock) and a maneuvering system.
                  • Maneuvering: RCS system on a cylinder is easy to design. Attachment: Put a handle on the container for the station's robotic arm. Open the outer airlock door and put the suits inside using the arm, then close the door and repressurize the airlock.
                    • Again, all that would have to get designed, tested, validated, and certified, and Scaled would have to be willing and able to put their time into it.

                      If you were going to go that route, why not use Orbital instead?

                      Or, just realize that all that isn't worth it for some spacesuits, and include them on the next Soyuz shipment.

    "By stranding our scientists on a dilapidated space station with faulty wiring, loose hardware, and malfunctioning air systems," NASA head Daniel Goldin said, "we have created extremely favorable conditions for learning about spaceborne panic."

    The two Russians and one American on board the station are reportedly terrified beyond lucidity.

    Among the groundbreaking experiments conducted on board Mir: a June 25 collision with a cargo craft that depressurized the Spektr module; last week's emergency power shortage, caused by a disconnected cable; and the periodic release of "dry ice" steam that simulates a shipboard fire. All have been deemed a huge success by agency heads.

    "They are in a constant state of what aerospace scientists term 'mind-shattering terror,' frightened for their very lives," Russian mission director Vladimir Solovyov said. "And we have not even used the hull-mounted Alien puppet that taps on the window yet."

    "We have also taken huge leaps in our understanding of the patterns created when one wets his pants in the weightlessness of space," Solovyov said. "The urine spreads out in an expanding sphere, something we did not expect."
