Force Is With Astronauts During Unexpected Spacewalk
NASA’s one-year spaceman, Scott Kelly, and astronaut Timothy Kopra took just a little more than a half-hour to release brake handles on the rail vehicle and help guide it 4 inches (10 centimeters) back into place. The rail vehicle had gotten stuck about four inches from its intended latching point, and the issue needed to be resolved by Wednesday, when a Russian cargo ship is expected to reach the station.

The vehicle serves as a mobile base for a Canadian-built robotic crane to move rails outside the station, a $100 billion research laboratory that files about 250 miles (400 km) above Earth.
After engineers on the ground confirmed the rail vehicle was latched in place, Hopkins told the spacewalkers, “It’s in a good config”.
“That was pretty easy”, Commander Scott Kelly said, according to a live broadcast of the spacewalk on Nasa television, after he hit the stuck brake handle and got the vehicle moving again.
The spacewalk lasted three hours and 16 minutes.
The mobile transport system is normally used to transport people and equipment, including the station’s big robot arm.
This will be the 191st spacewalk in support of space station assembly and maintenance, the third in Kelly’s career and the second for Kopra, who just arrived at the station.
It was the seventh spacewalk of the year.
The two astronauts spent the remaining time routing cables along the space station, and retrieving tools that had been stored on the side.
The railcar must be secured before the Progress resupply spacecraft, which launched early this morning, arrives at the station, bringing 2.8 tons (2.5 metric tons) of food and supplies.
Launch of the Progress cargo ship is scheduled for 3:44 a.m. EST on Monday from the Baikonur Cosmodrome in Kazakhstan, and also can be seen on NASA TV.
