Russia launched Progress MS-11 atop a Soyuz 2.1a rocket from Baikonur Cosmodrome in Kazakhstan to send supplies to the International Space Station. Following a successful orbital insertion, the autonomous cargo vehicle reached the station in just over three hours before autonomously docking with the Pirs module.
Liftoff took place at 11:01 UTC April 4, 2019, with a docking with Pirs at about 14:22 UTC. Monitoring the launch from the space station’s Zvezda module was Russian cosmonauts Oleg Kononenko and Aleksey Ovchinin of Expedition 59. Kononenko is the commander of the station’s six-person increment.
Had there been a problem during rendezvous, the two could have use the controls of the TORU, which is a backup manual docking system that can be used to remotely pilot the uncrewed spacecraft to the docking port. However, everything went by the book.
The rocket was rolled to pad 31/6 at Baikonur on April 1, and raised to the vertical position. The spacecraft is carried some 3,400 kilograms of supplies for the ISS. This included about 1,530 kilograms of propellant, 50 kilograms of oxygen and air and 400 kilograms of water.
