Outgoing space station commander Mike Fincke, flight engineer Yury Lonchakov and space tourist Charles Simonyi bid farewell to the Expedition 19 crew Tuesday and boarded a Soyuz ferry craft for re-entry and landing Wednesday in Kazakhstan.
Fincke and Lonchakov, launched to the International Space Station last Oct. 12, are wrapping up a 178-day stay off planet as the core members of the lab's 18th full-time crew. Simonyi, a wealthy software developer making his second paid trip to the station, took off March 26 with Expedition 19 commander Gennady Padalka and flight engineer Michael Barratt.
After a busy day of packing and readying the Soyuz TMA-13 spacecraft for re-entry, Fincke, Lonchakov and Simonyi shared hugs and handshakes with Padalka, Barratt and Japanese astronaut Koichi Wakata before floating into the ferry craft around 8:45 p.m. EDT. Hatches were closed a few moments later to set the stage for undocking just before midnight. Landing is expected around 3:16 a.m. Wednesday.
Undocking from the downward-facing port of the Russian Zarya module is targeted for around 11:55 p.m. EDT this evening. After moving a safe distance away and reaching the proper point in their orbit, Lonchakov will oversee a planned four-minute 21-second rocket firing at 2:24 a.m. that will slow the craft by about 258 mph and put it on the proper re-entry trajectory.
After falling to an altitude of about 87 miles, the three modules making up the Soyuz TMA-13 spacecraft will separate and the central descent module will enter the discernible atmosphere at an altitude of about 62 miles at 2:52 a.m. If all goes well, the module's main parachute will deploy shortly after 3 a.m. for a rocket-assisted touchdown at 3:16:29 a.m.
