Happening repressurization of the Expedition airlock at the termination of Saturday's spacewalk, a spacesuit prototype reason put Mastracchio's execute in probe for the addition spacewalk. A unused bring in of water entered the suit's sublimator -- the cooling system of the execute itself -- after the two astronauts had or fanatical themselves up to airlock umbilicals. As a determination, flight controllers crucial to amendment to a following execute for Mastracchio for the in the same way as spacewalk.
This reason is not associated to the spacesuit water leak that was seen from side to side a July spacewalk by European Disruption Workforce astronaut Luca Parmitano and NASA's Chris Cassidy. Both Mastracchio and Hopkins reported dry backdrop frequently all through Saturday's schedule and the two were never in care.
Mastracchio and Hopkins resized other suits in the Expedition airlock Sunday in the same way as allowing the execute Mastracchio wore Saturday to dry out. That spacesuit will be returned to skill in a extensively spacewalk.

One time preparing spacewalking kit and configuring the person concerned objects leave high and dry of the Expedition airlock Monday, the two NASA astronauts connected up via Shake off Builder Koichi Wakata of the Japan Aerospace Search Workforce to sum up the spacewalk's trial. Wakata will once again be in control of the station's robotic arm, Canadarm2, this time via Hopkins coupled to the foot settle at the end of the 57-foot arm.
Happening Tuesday's spacewalk Mastracchio and Hopkins will build up your strength the mega pump constituent from Superficial Shipment Prepare 3 and prepared it in the forte that is now empty lay down the denial of the besmirched pump Saturday. One time the spacewalkers spot on five electrical infrastructure and four poised infrastructure, introduction of the pump will equalize packed dual-loop cooling qualification for the station.
Mastracchio will be in the field of a execute distinctive via red stripes. Hopkins will wear a execute via no stripes. This will be the 176th spacewalk in buttress of space station gathering and money. It besides will be the addition Christmas eve spacewalk conducted in history. Fourteen years ago, space shuttle Finding astronauts Steve Smith and John Grunsfeld conducted an 8-hour, 8-minute spacewalk to prepared upgrades and new cover on the Hubble Disruption Fall.
If the spacewalk goes as unaffected Tuesday, all of the pump wallop work have got to be perfect via carnival two spacewalks. The besmirched pump, jejune from side to side Saturday's spacewalk, will live on the Goods Orbital Insubstantial Unit Temporary housing (POA) on the station's railcar, or Portable Deck Attempt. According to flight controllers, the besmirched pump can live on the POA until at least in the same way as June, based on a thermal rehabilitation by the ground control set up.
The nearby of the spacewalk will clear the way for Chief officer Oleg Kotov and Shake off Builder Sergey Ryazanskiy to assume their own spacewalk Friday out of the Pirs docking short to prepared a duo of high-fidelity cameras on the Zvezda skill constituent and to lift a few experiment parcels on the exterior of the Russian function of the station.
Shake off Builder Mikhail Tyurin assisted Kotov and Ryazanskiy on Monday via a "dry run" of the spacewalk as the two cosmonauts donned their Russian Orlan spacesuits and entered Pirs to test their suits.
