Cosmonauts Sergey Prokopyev and Dmitri Petelin floated outside the International Space Station Wednesday, unbolted an experiment airlock from the Rassvet docking compartment and then connected it to Russia’s Nauka multi-purpose laboratory module in a 7-hour, 11-minute excursion.

Track the progress of the Soyuz MS-01 spacecraft and its three-person crew through Wednesday’s countdown and launch, followed two days later by docking with the International Space Station on Friday.
