Spacewalkers Finalizing Repairs on Dark Matter, Antimatter Detector

Two astronauts switched their spacesuits to battery power this morning at 7:04 a.m., EST aboard the International Space Station to begin a spacewalk planned to last about six-and-a-half hours. NASA Flight Engineer Andrew Morgan and Expedition 61 Commander Luca Parmitano of ESA (European Space Agency) will venture outside the International Space Station to complete repairs on a cooling system for the Alpha Magnetic Spectrometer (AMS), a cosmic ray detector. The duo will conduct leak checks for the spectrometer's refurbished cooling lines and complete the work to resume operations of the cosmic ray detector.

Morgan is designated extravehicular crewmember 1 (EV 1), wearing the suit with red stripes, and with the helmet camera labeled #20. Parmitano is designated extravehicular crew member 2 (EV 2), wearing the suit with no stripes, and with helmet camera #18.

During the first three spacewalks in the complex series to repair the AMS, the astronauts carefully prepared the AMS and positioned materials, installed the upgraded cooling system, completed the power and data cable connection for the system. The intricate connection work required making a clean cut for eight existing stainless steel tube cooling lines connected to the AMS then connecting it to the new system through a process of metalworking known as swaging. Following the third spacewalk, the flight control team on Earth initiated power-up and confirmed the new system was receiving power and data.

In addition to revitalizing an important piece of scientific equipment, the process of creating the tools and procedures for these spacewalks is preparing teams for the types of spacewalks that may be required on Moon and Mars missions.

US EVA-65: During 3 previous EVAs last Nov/Dec, Morgan and Parmitano cut eight coolant lines in the AMS thermal control system and spliced in a replacement pump module; during today's EVA, the coolant system will be pressurized to make sure it's leak free

US EVA-65: Parmitano and Morgan, anchored to the end of the lab's robot arm, will be standing by to tighten/adjust coolant line fittings if required; if not, they'll re-install thermal insulation and, if time is available, move on to several lower-priority "get-ahead" tasks

US EVA-65: If all goes well, AMS controllers at CERN will re-charge the coolant system with CO2 Sunday and test the four pumps in the newly installed pump module Monday and Tuesday; science operations could resume as early as Wednesday

US EVA-65: Elapsed time: 0h 55m (07:59am): AMS coolant system leak checks are underway; Parmitano immediately noted a slight leak on the first two lines he checked; he tightened up fittings, but it will take an hour to make sure the procedure worked

US EVA-65: Clarifying: NASA now says just one coolant line was leaking; it has been tightened up, but it will take time to determine if line is now leak free
