In NPR's news item After A Year In Space, The Air Hasn't Gone Out Of NASA's Inflated Module there is a quote that's interesting:
"We do believe we've taken at least one hit," says Crusan. "Very small in nature, and actually we can't even visually see where it's at."
Crusan says there was no loss of pressure from the hit.
Without a leak, or a visible site, what is it that makes them think they've "taken a hit"? I assume it's a meteorite or particle impact they are referring to, right?
