It was the third attempt to execute the short two-orbit flight scheme for the Progress MS freighter, which required a coordinated effort to realign the orbit of the ISS. Two previous attempts were hindered by delays in the final moments of the countdown that exceeded narrow launch opportunities for the fast-track flight.
Russian cosmonauts Oleg Artemyev and Sergey Prokopyev were on board the station and ready to take over manual control of the craft should any problems occur, but the docking proceeded in a fully automatic mode. The craft has brought over 2.5 tons of water, fuel, food and other supplies, extending the entire crucial provision supply to at least mid-January 2019.
