Overview
- Progress MS-34, which launched Saturday from Baikonur on a Soyuz-2.1a, separated from the third stage and entered orbit en route to the International Space Station.
- Roscosmos said the cargo ship is following a roughly 48–49.5 hour flight with automated docking to the Zvezda aft port planned around 00:00 UTC on Tuesday.
- The mission is carrying about 2.5 tonnes of supplies, including 700 kilograms of propellant, 420 kilograms of drinking water, 50 kilograms of oxygen, and 1,348 kilograms of dry cargo for the Expedition 74 crew and station systems.
- The manifest includes a new Orlan-MKS spacesuit for Russian spacewalks plus experiments that study VR effects on balance and vision, stress impacts on the immune and nervous systems, bone loss, microbe effects on materials, and water recycling.
- While docked for roughly seven months, the Progress vehicle will perform station reboosts, then depart loaded with trash for a safe destructive reentry, with the next ISS cargo flights queued up on NASA’s CRS-34 in May and Progress MS-35 in June.
