“We threatened we would put astronauts in suits, in Dragon, to send a message to world that we disagreed,” one NASA official told Ars. “They didn’t care.”
Reaching a resolution
The standoff continued into Friday morning, when Russian astronauts appeared to back off their plans, only to subsequently approach the PrK module with a saw and the intent to remove a load-bearing bracket. Meanwhile, Roscosmos officials continued to ignore communication with NASA officials on the ground.
At this point, NASA directed Crew 12—US astronauts Jessica Meir and Jack Hathaway, French astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev into SpaceX’s Crew Dragon Freedom spacecraft—along with US astronaut Chris Williams, who had flown to the station in a Russian Soyuz spacecraft.
“We felt there was a very high probability of a bad outcome happening if they sawed that bracket off,” a NASA source said. NASA’s decision to send its astronauts into a safe haven prompted Roscosmos to finally back off.
In the days since, there has been some additional back-and-forth, but Russia has now told NASA it will decommission the PrK module.
Effectively, this means cosmonauts will no longer enter the PrK module or attempt to pressurize it. Progress vehicles will still be able to use the docking port to transfer fluids or perform other functions, but Russia will need to use other ports to move supplies on board the space station.
For NASA and the space station’s longevity, this agreement with Russia represents a significant step forward. For years, NASA has reluctantly accepted the risk of a rapid depressurization event on board the space station due to the PrK module’s issues. Now that risk should be retired.
