The Soyuz spacecraft carrying three new residents for the space station is scheduled for docking today at 7:18 p.m. EDT (2318 GMT).
The automated rendezvous sequence aboard the Russian-built crew transport capsule will begin about 4:58 p.m. EDT [20:58 UTC] to control the activities via autopilot.
The day's first key engine firing is planned for 5:20 p.m. [21:20 UTC] and another impulse is expected around 5:42 p.m. [21:42 UTC], followed within minutes by activation of the Kurs rendezvous equipment on both the Soyuz and space station to guide the linkup.
The two spacecraft should be within 60 miles of each other by 6:05 p.m. [22:05 UTC], closing to less than 10 miles by 6:30 p.m. [22:30 UTC]
The television camera on the nose of Soyuz will be turned on at 6:36 p.m. [22:36 UTC] to provide views of the docking.
A series of maneuvers between 6:43 and 6:51 p.m. [22:43-22:51 UTC] will dramatically slow the Soyuz's closure rate, ultimately leading to the spacecraft beginning a flyaround of the space station to align with the Poisk module's docking port.
After a stationkeeping hold by the Soyuz to ensure all is in readiness for docking, the spacecraft will commence final approach at 7:09 p.m. [23:09 UTC] for docking about 9 minutes later. Soyuz commander Alexander Samokutyaev will be standing by to take over manual flying of the spacecraft if required.
The linkup should occur at 7:18 p.m. EDT [23:18 UTC], shortly before an orbital sunset and two days and one hour after liftoff.
The hatch opening and welcoming ceremony aboard the station is expected around 10 p.m. EDT [02:00 UTC on Apr. 7th].
