The International Space Station’s mission managers are preparing for a likely unplanned spacewalk by Astronauts Scott Kelly and Tim Kopra no earlier than Monday, Dec. 21.
Late Wednesday, the Mobile Transporter rail car on the station’s truss was being moved by robotic flight controllers at Mission Control, Houston, to a different worksite near the center of the truss for payload operations when it stopped moving. The cause of the stall is being evaluated, but experts believe it may be related to a stuck brake handle, said ISS Mission Integration and Operations Manager Kenny Todd. Flight controllers had planned to move the transporter away from the center of the truss to worksite 2. The cause of the stall that halted its movement just four inches (10 centimeters) away from where it began is still being evaluated. Progress 62 is scheduled to launch at 3:44 a.m. EST Monday, and dock on Wednesday to the Pirs docking compartment at 5:31 a.m. Wednesday.
The ISS Mission Management Team met Friday morning and is targeting Monday for the spacewalk, but will meet again in a readiness review Sunday morning. Managers could elect to press ahead for Monday, or take an extra day and conduct the spacewalk Tuesday.
ISS Expedition 46 Commander Scott Kelly and Flight Engineer Tim Kopra of NASA will conduct the spacewalk. It will be the 191st spacewalk in support of space station assembly and maintenance, the third in Kelly’s career and the second for Kopra. Kelly will be designated Extravehicular Activity crew member 1 (EV1) wearing the suit bearing the red stripes, and Kopra will be Extravehicular Activity crew member 2 (EV2) wearing the suit with no stripes.
A start time for the spacewalk either Monday or Tuesday has not yet been set, but NASA TV coverage will begin 90 minutes prior to the start of the spacewalk.

Dear astronauts, about connection with Star wars just to ask “Are you driving in safely and carefully in the stars…..Stanislava
Be careful guys, we need everything to be OK for our Zero Robotics Finals!
Have a nice EVA. Our thoughts are always with you!

Nothing in Space is easy! Compare to unsticking a brake lever on earth….The ISIS and the cooperation between nations that it requires to maintain the most complicated and sophisticated machine ever built by humans is a often unsung or simply assumed and taken for granted-” of course earth has a permanent human-occupied space station orbiting our planet-why wouldn’t we?”. Meanwhile the contributions to our real daily lives and health, as well as the chance to gaze outward into the Universes past and Future, OUR Future, are myriad, diverse and practical. Godspeed Astronauts Kelly and Kopra in their “simple” repair EVA. Wave to us! I, for one, wish I was there to watch.
