The Soyuz MS-14 is the first piloted spacecraft, which was launched using the Soyuz-2.1a carrier rocket. In order to certify the system and ensure the safety of cosmonauts the launch on August, 22 was unpiloted and was successful without any issues.
This provides an opportunity to use this space complex for the crewed missions. However, during the docking of the ship a fault occurred in the ISS equipment responsible for the safe approach and airlocking. Therefore the Mission Control Center decided to withdraw the ship to a safe distance to ensure the safety of the crew.
The RSC Energia specialists offered the State Commission the following Soyuz MS-14 redocking variant:
- On August, 26 Alexander Skvortsov crew will manually redock the Soyuz MS-13 piloted ship from the Zvezda module to the Small Research Module-2, where the Soyuz MS-14 was meant to dock.
- On August, 27 the second automatic docking attempt will take place, with the Soyuz MS-14 docking to the Zvezda module.
Presently the Soyuz MS-14 is in normal spin in the Sun awaiting the redocking. Tomorrow Alexander Skvortsov will take an additional training according to the normal procedure using the onboard simulator to redock the Soyuz MS-13.
The situation is complicated, however is under control.

Regarding the Soyuz spacecraft docking
August 25, 2019, 06:00 GMT
On August 22, 2019 the Soyuz MS-14 unpiloted ship test launch took place according to the International Space Station flight program. On August, 24 due to the technical issues the automatic docking of the ship to the ISS was cancelled. To organize its docking, on August, 26 the Soyuz MS-13 piloted spacecraft will be redocked from the Zvezda service module to the Poisk Mini-Research Module 2 of the Russian segment of the ISS.
The estimated time of the Soyuz MS-13 detachment from the Zvezda module is at 03:34 UTC, the docking to the Poisk module is at 03:59 UTC. The whole operation will last for about 25 minutes. The docking will be performed manually by the ship’s commander Alexander Skvortsov with onboard engineers Luca Parmitano and Andrew Morgan taking part. On August, 25 the ISS crew is training to redock the spacecraft and carrying out its depreservation.
The redocking will be performed to free up the Zvezda service module docking unit, which will be used to dock the Soyuz MS-14 spacecraft on August 27, 2019 at 03:12 UTC.
