The uncrewed Russian Progress 78 spacecraft undocked from the International Space Station’s Poisk module at 7:42 p.m. EDT today and will arrive at the station’s Nauka Multipurpose Laboratory Module for redocking tomorrow.
Progress 78 will back out to a distance of 120 miles from the space station for a period of just over 24 hours to allow for station keeping. The cargo spacecraft will then make an automated docking at 12:23 a.m. Friday, Oct. 22, to the new module.
The maneuver will position Progress 78 to conduct leak checks of the Nauka module’s propellent lines before they are used with the new module’s thrusters for orientation control of the station. Progress 78 arrived at the station in July and will depart in late November.
