Uncrewed Russian Spacecraft Aborts Station Approach & Docking Attempt No Earlier Than Monday

At 1:36 a.m. EDT, Russian cosmonauts issued a command to abort the automated approach of an uncrewed Russian Soyuz spacecraft to the International Space Station after the craft was unable to lock onto its target at the station’s space-facing Poisk module.

The Soyuz MS-14 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21, at 11:38 p.m. EDT (8:38 a.m. Aug. 22 Baikonur time) on a test flight. It made 34 orbits of Earth en route to its anticipated docking to the station.

Following the abort, the spacecraft backed a safe distance away from the orbital complex while the Russian flight controllers assess the next steps.

Russian Spacecraft Docking Attempt No Earlier Than Monday

An uncrewed Russian Soyuz MS-14 spacecraft is now a safe distance away from the International Space Station following an abort during its final approach for a docking to the Poisk module.

After the cosmonauts on the station aborted an automated docking attempt early Saturday, Russian flight controllers told the crew on the station that early data indicates the issue that prevented its automated docking resides on the station’s side of the so-called KURS automated rendezvous system, not on the Soyuz itself.

The Soyuz is on a safe trajectory above and behind the space station that will bring it in the vicinity of the orbital complex again in 24 hours and 48 hours. Russian flight controllers have indicated the next earliest docking attempt could be Monday morning.

Possible cause of Soyuz MS-14 aborted docking

In the meantime, Russian controllers informed Expedition 60 commander Alexey Ovchinin and flight engineer Alexander Skvortsov of the Russian federal space agency Roscosmos they will send instructions to swap the signal amplifier of the station’s KURS docking system and test it before proceeding with another docking attempt.

The Soyuz launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21, at 11:38 p.m. EDT (8:38 a.m. Aug. 22 Baikonur time) on a test flight to validate the spacecraft’s compatibility with a revamped Soyuz booster rocket.
