Russia's Progress MS-08 cargo freighter, which has been attached to the International Space Station since February 2018, is set to undock with thousands of kilograms of unneeded equipment and trash. It is expected to remain in orbit on its own until late-August before performing a deorbit burn over the southern Pacific Ocean.
Undocking is planned for 02:14 UTC Aug 23, 2018. The spacecraft will back away from the outpost to a safe distance before loitering for about a week to perform experiments. After that, it will be commanded to deorbit at about 01:25 UTC Aug. 30 to burn up about 35 minutes later.
Progress MS-08 launched to the ISS atop a Soyuz 2.1a rocket from Baikonur Cosmodrome Feb. 13, 2018. It docked to the aft port of the Zvezda service module several days later at 10:38 UTC Feb. 15. The spacecraft carried 2,746 kilograms of cargo and supplies to the outpost, including 890 kilograms of propellant, 46 kilograms of oxygen and air and 420 kilograms of water.
