While the spacecraft were flying about 250 miles above Eastern Mongolia, an uncrewed Russian Soyuz spacecraft arrived and docked to the International Space Station at 11:08 p.m. EDT.

The Soyuz MS-14 spacecraft attached to the station’s aft-facing Zvezda module for a two-week stay as part of its test flight. The Soyuz delivers 1,450 pounds of cargo, including a Skybot F-850 humanoid robot, to the Expedition 60 crew currently residing on the orbital outpost.

The docking of the unpiloted Soyuz sets the stage for the robotic release of the SpaceX Dragon cargo craft Tuesday morning after a four-week stay at the station. The Dragon is filled with almost 2,700 pounds of valuable scientific experiments and other cargo. NASA Television and the agency’s website will broadcast its departure live beginning at 10:15 a.m. EDT.

Crew Relocates Russian Soyuz Spacecraft to Different Port

The Soyuz MS-13 crew ship
The Soyuz MS-13 crew ship is pictured docked the International Space Station’s Poisk module after successfully completing its relocation maneuver.

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.

Second Docking Attempt for Russian Spacecraft Planned for Monday Night

The Soyuz MS-14 Spacecraft
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.

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.

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.

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.

U.S. Cygnus Space Freighter Departs Station

Cygnus Departs the Station
The U.S. Cygnus space freighter from Northrop Grumman was released from the station’s robotic arm today at 12:15 p.m. EDT.

The Cygnus spacecraft successfully departed the International Space Station three months after arriving at the space station to deliver 7,600 pounds of supplies and scientific experiments to the orbiting laboratory.

The Cygnus spacecraft will now remain in orbit until mid-December and coincide with a second Cygnus spacecraft scheduled for launch to the space station in October. This will be the first extended duration flight to demonstrate spacecraft’s capability to fly two Cygnus vehicles simultaneously and support hosted payloads for longer periods of time.
