A functional check of the solar array panels involves standard deployment of photovoltaic sections and their artificial insolation with powerful lamps. This is done to test measure the parameters of solar power converters electric circuits. In addition to this, the descent vehicle special equipment was installed in the spacecraft, as well as crew personal equipment was prepared.

The Soyuz MS-17 with the ISS-63/64 expedition crew is scheduled to launch to the International Space Station on October 17, 2020 from the Baikonur Cosmodrome.
