US Astronauts fix stalled rail car during spacewalk

A pair of American astronauts stepped out on a three-hour spacewalk on Monday to move a stalled railcar outside the International Space Station, NASA said.

Tim Kopra and Scott Kelly made their way to the stuck “Mobile Transporter,” a rail car used to move supplies on the outside of the space station. Once complete, the astronauts will begin tackling other tasks since they’re out there.

These so-called “get ahead tasks” help cut down the time of future spacewalks, or leave room for more tasks to be added. The entire spacewalk is being live streamed, and you can watch it above.

This is Kopra’s second spacewalk ever, and Kelly’s third. Kelly, who is about nine months in to his historic year-long mission, has performed all three of his spacewalks this year.
