It’s time to come home! Expedition 39 astronauts Rick Mastracchio, Koichi Wakata and Mikhail Tyurin will climb into a Russian Soyuz spacecraft later today to make the trip back to Earth from the International Space Station. Much of the activity will play out on NASA TV, which you can watch above. Below are details about when to watch.
These are the descriptions from NASA about when the major events of the day occur. Bear in mind that all of these times are subject to change as circumstances warrant.
3 p.m. EDT / 7 p.m. UTC — Farewells and hatch closure (hatch closure scheduled at 3:15 p.m. / 7:15 p.m. UTC )
6:15 p.m. EDT / 10:15 p.m. UTC — Undocking (undocking scheduled at 6:33 p.m. / 10:33 p.m. UTC)
8:45 p.m. EDT / 12:45 a.m. UTC — Deorbit burn and landing (deorbit burn scheduled at 9:03 p.m. EDT /1:03 a.m. UTC landing scheduled at 9:57 p.m. EDT / 1:57 a.m. UTC)
The crew is expected to land near Dzhezkazgan in Kazakhstan. After doing some quick medical checks on site, the crew will be flown out separately to do more detailed testing at their local medical centers.
With Wakata flying home, the station is now under the command of Expedition 40 NASA astronaut Steve Swanson, who will oversee activities there along with Alexander Skvortsov and Oleg Artemyev. The rest of the Expedition 40 crew should fly to station May 28, if all goes to plan.
