if your mind's habit is to run the disaster movie — what if this goes wrong, what if that does — chris hadfield's answer will sound backwards at first. he doesn't try to stop it. he does it harder, on purpose, and then he goes and answers it.
he grew up in ontario, joined the forces at 18, flew cf-18s, became a test pilot, and in 1992 was picked as a canadian astronaut. three spaceflights: mir in 1995, the space station in 2001, and in 2012–13 the long stay that made him the first canadian to command the iss and, a day before he came home, the man singing space oddity in orbit. his book, an astronaut's guide to life on earth (2013), is largely about the mind, and the question underneath it is one he says he asks constantly: what's the next thing that could kill me?
nasa and the canadian space agency build training around that question. they call them contingency sims — instructors fake a fire, a leak, a crewmate dying during launch, and the crew lives through the worst version before it can happen for real. he once brought his wife to one, the one where a crew member dies, so she could see how everyone — including him — would actually behave if it were him. the point isn't to be fearless. it's to turn a free-floating dread into a specific, rehearsed, answerable problem. his line from the book: "in my experience, fear comes from not knowing what to expect and not feeling you have any control over what's going to happen."
april 2001
the test came on his first spacewalk, on the 2001 mission to the station. he'd polished the inside of his visor with anti-fog before going out. in vacuum and sunlight the residue mixed with the moisture in his eyes and — no gravity, so nothing drains — spread across both of them and stayed. "both my eyes are blind. and try as i might, i couldn't get them open." and: "i couldn't rub it because it's inside my helmet."
floating outside a space station, blind, tethered, mid-task. he didn't abort and he didn't panic. he kept doing what he could by touch and memory, vented a little oxygen from his suit to help flush his eyes, and in something like twenty minutes could see enough to carry on and finish the walk. asked how, he's almost boring about it: "we're just meticulously prepared. we dissect what it is that is going to scare us... and then we practice over and over again."
the racing thought isn't the enemy. an unanswered racing thought is. so answer it — specifically, out loud, in advance.
sweat the small stuff
the companion idea is the one people find least romantic. "an astronaut who doesn't sweat the small stuff is a dead astronaut." caring intensely about small boring details — the checklist item, the warning light, the visor — isn't anxious over-checking, in his telling. it's what buys the calm when something big and unplanned goes wrong. by the time he commanded the station in 2013 the method wasn't a technique any more; it was just how his mind ran. "the greatest antidote for fear is competence."
the honest ledger
'what's the next thing that could kill me' is how he sums up his own method in interviews; it couldn't be confirmed as a verbatim sentence from the book, so it's given as his framing, not a quote. the npr line is trimmed. and none of this is a treatment — it's one very well-trained man's account of what worked for him.
for the noise, borrow the shape: pick the worry that's loudest, make it specific — not 'it'll go wrong' but exactly how — and then, tonight, work out what you'd actually do. see how much quieter it is once it has an answer.
