Specialists at the Baikonur Cosmodrome have begun unpreserving the Soyuz MS-26 manned spacecraft, which has been in storage mode for about six months.
The manned spacecraft has already been inspected and prepared for upcoming electrical tests of onboard systems equipment and a number of other mandatory pre-flight tests.
The launch of Soyuz-2.1a with Soyuz MS-26 is scheduled for September. The ISS has already begun preparations for the upcoming launch and docking with the Soyuz MS-26 spacecraft and the landing of Soyuz MS-25. Cosmonauts have corrected the ISS orbit. Also, the day before, new blocks of the Russian Soyuz rocket for the launches of Progress MS-29 and Soyuz MS-26 arrived at Baikonur.
Soyuz MS-26 will go into Earth orbit tentatively on September 11. The main crew includes Roscosmos cosmonauts Alexey Ovchinin and Ivan Wagner, as well as NASA astronaut Donald Pettit.
The return to Earth of the Soyuz MS-25 spacecraft with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub and NASA astronaut Tracy Dyson is expected on September 23.
