Progress MS-08 also includes two nanosatellites: Tanyusha YuZGU-3 (1998-067PJ) and Tanyusha YuZGU-4 (1998-067PK) (a.k.a. Radioskaf RS-8 and Radioskaf RS-9) with a mass of 2.5 kg, which was developed jointly by RKK Energia and students at the South-Western State University, YuZGU, in the city of Kursk. The satellites will be launched by spacewalking cosmonauts.

Undocking and decay

Undocking on 23 August 2018, at 02:16 UTC. And decay in the atmosphere and its debris entered the Pacific Ocean, on 30 August 2018.
