Is this the first spacewalk in the new Orlan type?
But I doubt and think that #4 will be used instead of #6
To configure the Progress M-02M/33P cargo ship, docked at the “Pirs” DC1 nadir port, for ground-commanded emergency undocking if it should become necessary during the use of the DC1 airlock for the EVA-22, Romanenko & Padalka –Activated the Progress (i.e., SUBA/Onboard Equipment Control System & SOTR/Thermal Control System),Removed the air heater/fan unit & air duct in the passageway,Released the quick-release screw clamps which rigidize the docking joint (with RS/Russian Segment thrusters inhibited during the closing-up activities),Took documentary video of the DC1/Progress interface prior to hatch closure and downlinked the video via Ku-band for ground inspection,Closed the hatches, andPerformed the usual one-hour leak check on the vestibule between the DC1-SU & SU-33P hatches to test for hermeticity.
Is this need to be able to undock automatically just so that it will be possible at all to undock the Progress or is it necessary to undock immediately during the spacewalk as part of an emergency response?
Thank you anik. I guess I just don't know what emergency steps would be involved if faced what this situation of an inability to repressurize.
