NASA astronauts briefly sheltered in their SpaceX Crew Dragon capsule on Friday during a Russian repair attempt on a leaky transfer tunnel of the International Space Station. The work was later halted for further analysis, and the crew resumed their normal tasks on the space station, which orbits about 250 miles above Earth.

NASA astronaut Don Pettit shared a timelapse video showing crystal growth in microgravity, revealing unique patterns.

Astronauts aboard the International Space Station were earlier ordered by NASA to shelter in their spacecraft and prepare for potential evacuation as a Russian crew attempted to fix a worsening air leak.

Six days from now, NASA will stand four astronauts in front of cameras at Johnson Space Center and tell the world who will attempt the first crewed lunar landing since Apollo 17 returned to Earth in December 1972.

USA TODAY's Eric Lagatta explains why NASA lifted a brief shelter order on the ISS as crews assessed ongoing air leaks in the Russian segment.
