The Crew Dragon docked at the space-facing port of the lab’s forward Harmony module at 3:15 p.m. EST, 34 hours after launch Friday from the Kennedy Space Center atop a Falcon 9 rocket.

In a rapid-fire crew rotation, a NASA astronaut and two Russian cosmonauts are packing up for the trip back to Earth Saturday, leaving the International Space Station just eight days after the arrival of another three-person crew and three weeks before their own replacements arrive to boost the lab’s crew back to six.
