“Flight controllers in Houston are continuing to monitor station’s cabin pressure in the wake of the repair,” added NASA. “Meanwhile, Roscosmos has convened a commission to conduct further analysis of the possible cause of the leak.”
According to the Russian news agency TASS, the sealant used to fix the leak has proven to be airtight, so it looks like the problem has been solved. The pressure on the ISS remains stable, with no further leaks having been detected. While a micrometeoroid is a possible culprit for this leak, it could also have been the result of a faulty seal or valve.
“Anytime you’re connecting something, it’s just like a jar where you have a lid on it and it’s got a little rubber seal,” University of Buffalo aerospace engineer John Crassidis told Space.com. “That rubber seal might break down and start leaking.”
If it was the result of a micrometeoroid, this will not be the first time the station has been hit – and nor will it be the last. The ISS is designed to survive events like this, and while it is rare for a hole to be created, this incident won’t have any impact on the station’s operations going forwards.
