Live coverage: International crew lands in Kazakhstan

These photos chronicle the activities of Russian cosmonaut Fyodor Yurchikhin and NASA astronaut Jack Fischer on Thursday as they prepared for liftoff on a Soyuz rocket to begin an expedition of more than four months on the International Space Station.

The Cygnus commercial logistics vehicle departed the International Space Station Sunday morning for a week-long free-flight filled with autonomous science tasks before re-entry.

After a one-day delay to wait for improved conditions in the offshore abort zone, SpaceX and NASA launched four astronauts at 5:49 a.m. EDT (0949 GMT) Friday aboard a Falcon 9 rocket and Crew Dragon spaceship from Kennedy Space Center in Florida. The astronauts docked with the International Space Station at 5:08 a.m. EDT (0908 GMT) Saturday for a planned six-month mission.
