0120 GMT (9:20 p.m. EDT Thurs.)
Welcome aboard! The newest residents are floating into the International Space Station from their Soyuz capsule for the formal ceremony. Also participating via a live communications linkup are the VIPs gathered on the balcony in Russia's mission control center outside Moscow.

The outpost's Expedition 24 crew is comprised of three Russians and three Americans. And it's the first time that an Expedition crew has included two women.

0101 GMT (9:01 p.m. EDT Thurs.)
The hatchway between the Soyuz spacecraft and the station was opened at 8:52 p.m. EDT following the successful completion of leak checks. The welcoming ceremony is expected to begin shortly when a live television downlink communications session starts.
2232 GMT (6:32 p.m. EDT)
The docking probe on the front of Soyuz has retracted, allowing the hooks and latches to close and form a seal between the capsule and station. Pressure and leak checks will be performed over the next orbit before the hatchway is opened for the crew to enter into the station later this evening.
2223 GMT (6:23 p.m. EDT)
The docking occurred as the space station flew over the Atlantic just off the coast of Argentina at an altitude of 222 miles.

Over the next few minutes, the Soyuz docking probe will retract to allow hooks and latches to bring the spacecraft to a firm seal with the station. Hatches between the two vehicles will be opened around 9:25 p.m. EDT.

2221 GMT (6:21 p.m. EDT)
DOCKING. The Soyuz TMA-19 spacecraft has docked to the Zvezda module of the space station, delivering Doug Wheelock, Shannon Walker and Fyodor Yurchikhin to the international outpost.

The new Expedition 24 residents join commander Alexander Skvortsov and flight engineers Mikhail Kornienko and Tracy Caldwell Dyson. They have been aboard the station since April.

2220 GMT (6:20 p.m. EDT)
A steady, stable approach using Soyuz's automated rendezvous system continues.
2220 GMT (6:20 p.m. EDT)
About 60 feet to go.
2219 GMT (6:19 p.m. EDT)
The capsule remains on course and lined up for docking.
2219 GMT (6:19 p.m. EDT)
Now 80 feet and closing.
2218 GMT (6:18 p.m. EDT)
Inside 100 feet.
2217 GMT (6:17 p.m. EDT)
About 140 feet left to go.
2216 GMT (6:16 p.m. EDT)
The docking mechanism has been powered up.
2216 GMT (6:16 p.m. EDT)
Soyuz has closed to within 175 feet from the station.
2215 GMT (6:15 p.m. EDT)
The capsule is keeping a good alignment with the docking target on the station.
2214 GMT (6:14 p.m. EDT)
Range to docking inside 260 feet.
2213 GMT (6:13 p.m. EDT)
Now less than 400 feet to docking.
2213 GMT (6:13 p.m. EDT)
The Russian flight control team has given approval and the final approach has commenced.
2212 GMT (6:12 p.m. EDT)
The range between Soyuz and station is about 470 feet.
2210 GMT (6:10 p.m. EDT)
The capsule is completing a roll maneuver as part of the sequence to prepare for docking.
2209 GMT (6:09 p.m. EDT)
The Soyuz completed the flyaround to align with the docking port. It's now in the stationkeeping hold about 720 feet away while controllers verify all is in readiness for final approach.
2208 GMT (6:08 p.m. EDT)
About 840 feet separate the two spacecraft as the Soyuz continues its intercept.
2207 GMT (6:07 p.m. EDT)
At present, the Soyuz and station are flying over the southeastern Pacific. The docking is set to occur over the Atlantic, just off the southeastern coast of South America.
2205 GMT (6:05 p.m. EDT)
Soyuz is flying itself around the international outpost to get into the approach corridor leading to the Zvezda module's docking port.
2202 GMT (6:02 p.m. EDT)
The capsule is within 3,000 feet of the outpost now.
2200 GMT (6:00 p.m. EDT)
The Soyuz spacecraft is nearing the space station for docking a little less than 30 minutes from now at 6:25 p.m. EDT. You can watch live NASA Television coverage on the right-hand column of this page.
The Soyuz spacecraft carrying three new residents for the space station is scheduled for docking Thursday evening at 6:25 p.m. EDT (2225 GMT).

The automated rendezvous sequence aboard the Russian-built crew transport capsule will begin about 4:06 p.m. EDT to control the activities via autopilot.

The day's first key engine firing is planned for 4:28 p.m. and another impulse is expected around 4:51 p.m. EDT, 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 5:12 p.m., closing to less than 10 miles by 5:37 p.m.

The television camera on the nose of Soyuz will be turned on at 5:45 p.m. to provide views of the docking.

A series of maneuvers between 5:53 and 6:00 p.m. will dramatically slow the Soyuz's closure rate, ultimately leading to the spacecraft beginning a flyaround of the space station to align with the Zvezda service 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 6:16 p.m. for docking about 9 minutes later. Soyuz commander Fyodor Yurchikhin will be standing by to take over manual flying of the spacecraft if required.

The linkup should occur at 6:25 p.m. EDT, a few minutes after orbital sunset.

The hatch opening and welcoming ceremony aboard the station is expected around 9:25 p.m. EDT.

SUNDAY, JUNE 13, 2010
A Russian-made Soyuz booster rocket and its crew transport capsule were transported by rail from the final assembly building to the launch pad Sunday in preparation for this week's trip to the International Space Station.

Liftoff of two Americans and a Russian cosmonaut is scheduled for Tuesday at 5:35 p.m. EDT (2135 GMT) from the Baikonur Cosmodrome in Kazakhstan.

NASA's Doug Wheelock and Shannon Walker, plus Russian cosmonaut Fyodor Yurchikhin are headed to the orbiting outpost for a six-month mission as part of the Expeditions 24 and 25.

They'll join the trio already living up there -- commander Alexander Skvortsov, cosmonaut Mikhail Kornienko and American astronaut Tracy Caldwell-Dyson.

The Soyuz rocket completed its rollout Sunday morning. Mounted horizontally on a railcar, the launcher journeyed along a winding route from the integration facility at Site 254 to the same historic pad used since the dawn of the space age.

Hydraulic pistons lifted the rocket upright on the pad and gantry swing arms moved into position to enclose the vehicle. Technicians on four levels hooked up electrical and telemetry cables between the rocket and pad.

Following liftoff of the three-stage, liquid-fueled booster, the capsule will be inserted into a preliminary orbit within nine minutes. But it will take two days for the Soyuz TMA-19 spacecraft to the reach station. Docking to the Zvezda module is scheduled for Thursday at 6:25 p.m. EDT (2225 GMT).

Here is an overview the key events in the Soyuz's launch countdown, as provided by NASA:
