After a two-orbit, three-hour journey, the Soyuz will dock to the space station’s Rassvet module at 1:11 p.m. About two hours after docking, hatches between the Soyuz and the station will open and the crew members will greet each other.

Once aboard the ISS, the trio will join Expedition 67 Commander Oleg Artemyev, cosmonauts Denis Matveev and Sergey Korsakov of Roscosmos, as well as NASA astronauts Bob Hines, Kjell Lindgren, and Jessica Watkins, and ESA (European Space Agency) astronaut Samantha Cristoforetti. Rubio, Prokopyev, and Petelin will spend six months aboard the orbital laboratory.

This will be Prokopyev’s second flight into space and the first for Rubio and Petelin.
