The launch from the Baikonur Cosmodrome in southern Kazakhstan occurred at 1:45 am ET on Wednesday.
The trio’s Soyuz capsule is expected to dock with the space station at 4:52 a.m. ET, and the hatch between the space station and the capsule will open at 6:45 a.m. ET, allowing them to enter the station.
This is the second spaceflight for Rubins and Ryzhikov and the first for Kud-Sverchkov, and they will spend six months on the space station.
Along for the ride is Yuri, a little cosmonaut knitted by Kud-Sverchkov’s wife Olga. He serves as the crew’s zero gravity indicator. Essentially, once he begins to float, the crew will know they’ve reached space. Each crew gets to pick their own indicator, according to NASA.
