Soyuz Orbital Insertion to Docking Timeline
Once the Soyuz reaches orbit, it spends two days chasing the International Space Station. The crew performs systems checks and keeps in touch with controllers at the Russian Mission Control Center during that time.

Before the final rendezvous phase, the three crewmembers put on pressurized suits and then monitor the automated docking sequence. Once docking is complete, they equalize the air pressure of the Soyuz with the station before opening the hatches.

The following times are approximate. All times are keyed to elapsed time from liftoff. Each orbit takes approximately 90 minutes.

FLIGHT DAY 1 OVERVIEW
