The ISS Crew Just Practiced for the One Scenario NASA Hoped to Avoid
For about two hours on Friday, five astronauts strapped into their return spacecraft and prepared to abandon the International Space Station—a drill that, until recently, was almost unthinkable. The leak that drove them there isn't a surprise glitch; it's the worsening of a known problem that NASA and Russia have been managing for years. What changed Friday is that the crew rehearsed evacuation for real.
Bottom Line
This was a precaution, not a catastrophe—the crew is fine and back at work. But practicing evacuation marks a quiet escalation in how seriously a long-known leak is being treated, and it underscores that American astronaut safety is tied to repairs on the Russian segment of a station neither partner can run alone. The signal is a trend, not a blip.
