Space Station

A Russian Progress cargo ship loaded with more than 5,500 pounds of supplies and equipment bound for the International Space Station blasted off from Kazakhstan early Friday, kicking off a two-day orbital chase.

Astronauts Jasmin Moghbeli and Loral O’Hara worked outside the International Space Station Wednesday to replace a bearing assembly in one of the lab’s solar array rotation mechanisms. But the task took longer than expected and they were unable to retrieve a failed electronics box as planned.

Two Russian spacewalkers floated outside the International Space Station Wednesday and isolated a leaking radiator as planned, apparently causing residual coolant still trapped inside to make its way to the leak site and spew out into space.

NASA astronaut Frank Rubio and two Russian cosmonauts undocked from the International Space Station and plunged back to Earth early Wednesday, landing on the steppe of Kazakhstan to close out an unexpected yearlong stay in space, the longest single flight in U.S. space history.

Two Russian cosmonauts and a NASA astronaut return to Earth after an extended tour of duty aboard the International Space Station. The landing marked the end of a 370-day-21-hour-22-minute-long mission. It was the third longest human space flight in history and the longest by a U.S. astronaut.
