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.

A normally reliable Soyuz FG rocket malfunctioned two minutes after liftoff from Kazakhstan Thursday, forcing a Russian cosmonaut and his NASA crewmate to execute an emergency abort and a steep-but-safe return to Earth a few hundred miles from the launch site.
