Progress 86 Successfully Docks with ISS Despite Autopilot Glitch

Manual intervention by cosmonauts ensures delivery of critical supplies to Expedition 70 crew.

Roscosmos' Progress 86 spacecraft successfully docked with the International Space Station (ISS) on December 3, 2023, delivering nearly three tons of supplies for the Expedition 70 crew.
The spacecraft was launched from Kazakhstan on a Soyuz rocket on December 1, 2023.
Due to a glitch in the automated rendezvous system, the docking was manually controlled by Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub from inside the ISS.
The cargo includes food, fuel, equipment, and supplies, along with scientific equipment, nitrogen, water, and propellant used to help maintain the station's orbit.
Progress spacecraft are a pivotal component of Russia's space program, designed for resupply missions to space stations, and have evolved through several variants since their inception in the 1970s.
