NASA TV Broadcasting Second Docking Attempt of Russian Spacecraft
The Soyuz MS-14 spacecraft is pictured during its first docking attempt early Saturday.
Beginning at 10:30 p.m. EDT Monday, NASA Television and the agency’s website will air the arrival and docking to the International Space Station of an uncrewed Russian Soyuz spacecraft. The Soyuz MS-14 is scheduled to dock to the station’s aft-facing Zvezda module at 11:12 p.m.
It is the spacecraft’s second attempt to dock to the station after cosmonauts aborted its first attempt Saturday at 1:36 a.m. because of a problem on the station’s side of the so-called KURS automated rendezvous system that prevented its automated docking. The Soyuz has been on a safe trajectory above and behind the space station.
To enable the second attempt, three Expedition 60 crew members boarded their Soyuz MS-13 spacecraft Sunday night and relocated it from the Zvezda module to the Poisk module, making the Zvezda port available.
The uncrewed Soyuz launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21 on a test flight to validate the spacecraft’s compatibility with a revamped Soyuz booster rocket. The booster will be used to transport crews to the International Space Station beginning in spring 2020.

At 11:59 p.m. EDT, the Soyuz MS-13 spacecraft with three Expedition 60 members inside successfully docked to the International Space Station’s Poisk module. The crew of Alexander Skvortsov of Roscosmos, Luca Parmitano of ESA (European Space Agency) and Andrew Morgan of NASA began the relocation maneuver when they undocked from the aft port of the station’s Zvezda module at 11:35 p.m.
Skvortsov flew the spacecraft, backing about 124 feet (38 meters) away from the space station before completing a roll maneuver to take them to the Poisk module for the manual docking.
The move frees the port for an uncrewed Soyuz MS-14 that currently is on a safe trajectory above and behind the space station to execute a second docking attempt Monday night to the Zvezda port. The so-called KURS automated rendezvous system has been tested and is in perfect working order. NASA TV coverage of the docking Monday night will begin at 10:30 p.m. with docking scheduled at 11:12 p.m.
The uncrewed Soyuz launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21 on a test flight to validate the spacecraft’s compatibility with a revamped Soyuz booster rocket. The spacecraft will deliver 1,450 pounds of cargo to the Expedition 60 crew.
The last relocation of a Soyuz was in August 2015 when Gennady Padalka and Mikhail Kornienko of Roscosmos and NASA’s Scott Kelly conducted a similar operation, but in reverse, flying their Soyuz TMA-16M spacecraft from Poisk to Zvezda.

At 11:35 p.m. EDT, the Soyuz MS-13 spacecraft with three Expedition 60 members inside undocked from the International Space Station’s Zvezda service module. They are beginning a 25-minute journey to relocate their spacecraft to the to the Poisk module.
Alexander Skvortsov of Roscosmos, Luca Parmitano of ESA (European Space Agency) and Andrew Morgan of NASA donned their Russian Sokol launch and entry suits before climbing aboard their Soyuz for the relocation maneuver.
The relocation will accommodate a second rendezvous and docking attempt for an uncrewed Soyuz MS-14 spacecraft on Monday night. The uncrewed 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. Cosmonauts aborted its first attempt to dock on Saturday at 1:36 a.m. because of a problem on the station’s side of the so-called KURS automated rendezvous system that prevented its automated docking.

Second Docking Attempt for Russian Spacecraft Planned for Monday Night
The Soyuz MS-14 spacecraft is pictured during its first docking attempt early Saturday.
International Space Station managers and the international partners met on Saturday and approved a plan to allow a second rendezvous and docking attempt for the unpiloted Soyuz MS-14 spacecraft to occur on Monday night. The Soyuz’ initial docking attempt early Saturday was aborted after what Russian officials said was a suspected problem with a component associated with the Kurs automated rendezvous system for the Poisk module docking port.
The Soyuz was commanded to back away from the station after approaching to within 100 meters of Poisk when the vehicle could not achieve a solid telemetry lock to that docking port through the automated rendezvous system. The unpiloted Soyuz is currently orbiting a safe distance from the ISS with all of its systems functioning normally. The six crewmembers on board the station were never in any danger during the initial rendezvous attempt.
Plans now call for the unpiloted Soyuz to execute a second docking attempt Monday night at 10:12 p.m. Central time, 11:12 p.m. Eastern time, but this time to the aft port of the Zvezda Service Module. The Kurs system on Zvezda has been checked out and is in perfect working order. NASA TV coverage of the docking Monday night will begin at 9:30 p.m. Central time, 10:30 p.m. Eastern time.
To accommodate the new plan, Expedition 60 crewmembers Alexander Skvortsov of Roscosmos, Luca Parmitano of the European Space Agency and Drew Morgan of NASA will don their Russian Sokol launch and entry suits Sunday night, climb aboard their Soyuz MS-13 spacecraft which docked to Zvezda on July 20 and undock for a 25-minute Soyuz relocation maneuver and a manual docking by Soyuz commander Skvortsov to the Poisk module. The suspect Kurs rendezvous unit component for Poisk is not a factor for the relocation maneuver by Skvortsov and his Soyuz crewmates.
NASA TV coverage of the relocation will begin Sunday night at 10 p.m. Central time, 11 p.m. Eastern time. Undocking of the Soyuz MS-13 spacecraft from Zvezda is scheduled at 10:34 p.m. Central time, 11:34 p.m. Eastern time with redocking to Poisk scheduled at 10:59 p.m. Central time, 11:59 p.m. Eastern time.
It would be the first Soyuz relocation since August 2015 when Gennady Padalka and Mikhail Kornienko of Roscosmos and NASA’s Scott Kelly conducted a similar operation, but in reverse, flying their Soyuz TMA-16M spacecraft from Poisk to Zvezda.
The docking of the unpiloted Soyuz Monday night will preserve the robotic release of the SpaceX Dragon cargo craft Tuesday morning after a four-week stay at the station. Dragon will be deorbited for a parachute-assisted splashdown several hours later in the Pacific Ocean, bringing home cargo and valuable scientific experiments from the orbital laboratory.

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.
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.
