NASA ordered astronauts on the International Space Station to shelter in their spacecraft and prepare for possible evacuation after a worsening air leak in the Russian Zvezda service module's transfer tunnel. The Guardian reports: The four astronauts of NASA's Crew-12 mission on the station -- two US astronauts, a French astronaut and a Russian cosmonaut -- received orders from NASA mission control at 9.04am ET (2pm BST) on Friday to enter their Crew Dragon spacecraft docked to the station and don their spacesuits in case the air leak warranted an emergency evacuation, a NASA official said.
NASA and Russia's space agency Roscosmos, the station's two primary operators, have debated for months over the cause and potential fixes of small air leaks onboard Russia's Zvezda service module, a key structure of the football-pitch-sized laboratory. The air leaks have been relatively minor in recent months. But on Monday the problem escalated from a pound of air per day to two pounds (0.9kg) a senior Nasa official told Reuters on condition of anonymity. UPDATE: "Roscosmos has paused Friday's structural repair efforts inside the Zvezda service module transfer tunnel, known as PrK, as more measurements and data is assessed," Bethany Stevens, a spokesperson for NASA, posted on X.
"Given this development, NASA has instructed the crew members inside the Dragon spacecraft to end the safe haven procedures and return to planned operations aboard the International Space Station. We look forward to working with Roscosmos on a collaborative approach to address the leaks."
