NASA to Make Critical ISS Repairs During Spacewalk on Monday
NASA announced Friday that it will send astronauts on an unscheduled spacewalk from the U.S. Quest airlock on the International Space Station just days before the holiday.

The primary objective of the spacewalk by American Nasa astronauts Tim Kopra and Scott Kelly was to free a jammed robotic trolley. The rail auto needed to be moved so a cargo ship filled with almost 3 tons of food and supplies could dock at the orbiting space lab on Wednesday.
The auto serves as a mobile base for a Canadian-built robotic crane to move rails outside the station, a US$100bil (RM430bil) research laboratory that files about 250 miles (400 km) above Earth.
The problem began last week when the mobile transporter rail vehicle, a piece of moveable equipment that is attached to the Canadarm2 robotic arm, began to move to another work site. The spacewalk will be shown live on NASA TV starting at 5:30 a.m. CST (11:30 GMT).
In Mission Control, astronaut Mike Hopkins cautioned them to avoid making accidental contact with the rail vehicle since it wasn’t secured into its usual spot.
After a stuck brake handle stalled a railcar outside of the ISS, two astronauts set out on a ‘spacewalk, ‘ on Monday to fix the auto in time for an upcoming docking.
If the brake was somehow inadvertently engaged, it may be an easy task to unstick it. The astronauts may then turn to a few other get-ahead tasks as part of their ongoing maintenance and upgrades of the ISS.
‘It’s in a good config, ‘ Hopkins said to the astronauts.
Kelly and his fellow spacewalker, USA flight engineer Tim Kopra, made swift work of the job and accomplished their main mission in less than an hour.
The Progress MS/62P cargo ship, launched from the Baikonur Cosmodrome in Kazakhstan at 3:44:39 a.m., is the first in a new series of spacecraft featuring an upgraded command and telemetry system, new digital video gear for proximity operations and additional redundancy in a manual control backup system.
This spacewalk was the seventh one this year, but operated under significantly less planning than normal.
Mr Peake said Major Peake’s two sons, Thomas, six, and Oliver, four, were both “fine”, adding: “They’ve become used to the idea that Daddy’s up on the space station so they’ll be following his adventures along with the rest of us”.
