House and the open ocean: On the floor, it looks as if two extra wildly contrasting locations couldn’t presumably exist. However quite the opposite, the 2 are extra intently tied than you suppose. And individuals who have been to the farthest reaches of each can attest to the actual fact. As a result of because it seems, the sorts of coaching and expertise required and the environments you discover in each have spectacular parallels.
Simply ask aeronautical engineer, astronaut, and aquanaut Nicole Stott. She’s spent 104 days in house on the House Station and House Shuttle and loads of time underwater, partially in preparation for house journey, but in addition for enjoyable and training now that she spends most of her time on planet Earth.

The PADI-certified (Skilled Affiliation of Diving Instructors) diver confirms that beneath sea and outer house have rather a lot in frequent. In any case, each are excessive environments that aren’t solely laborious to entry, however usually outright harmful, require extremely specialised gear to navigate, and are inhospitable to people. Which seems to be fairly handy, as a result of whereas simulating the dearth of gravity and the vacuum of house may be difficult, the ocean provides a authentic analog and impressively simulative coaching grounds.
In truth, astronauts, earlier than they even take into consideration setting foot in a shuttle to journey past Earth’s ambiance, should spend time underwater. There’s even a devoted coaching middle for it: the Impartial Buoyancy Laboratory in Houston that exists to coach astronauts for house walks. Inside, one of many world’s largest indoor swimming pools—measuring 202 ft lengthy, 102-feet extensive, and 40 ft deep and containing 6.2 million gallons of water—can also be house to replicas of Worldwide House Station elements, in addition to different man-made constructions in house.

On this pool, astronauts don 300-pound fits plus loads of different gear to realize impartial buoyancy, and submerge themselves, surrounded by a crew of assist divers, to be taught and really feel like what it is going to be wish to function and transfer about in house. In truth, in accordance with Stott, it’s the closest feeling you may obtain on Earth that simulates what it’s like to maneuver in house (minus the drag and weight you expertise underwater).
In any case, in each locations, you’re floating—although within the water since you’re buoyant and in house as a result of there’s no gravity—and in neither are you able to merely name it a day, throw off your helmet or respirator, and stroll house.
Which is why Stott and others have additionally skilled within the Aquarius Lab, an underwater habitat and aquanaut basecamp 60 ft beneath the floor of the ocean off the Florida Keys. She spent 18 days beneath the floor. Down there, “you’re in an actual, true, excessive surroundings,” Stott explains, identical to you’d be in house—although with way more atmospheric stress. However being at these depths doesn’t simply simulate the actions and teamwork required outdoors Earth’s ambiance, it mimics the sense of isolation and self-reliance, too.
“You possibly can’t simply bail,” Stott explains. Whenever you’re underwater at vital depths, your physique and blood develop into too saturated with nitrogen to shortly retreat to the floor in the event you run into bother. Achieve this, and the surplus nitrogen could cause bubbles in your blood and/or lungs, inflicting severe bodily hurt and decompression sickness and even demise by way of arterial fuel embolism. At Aquarius’ depth, Stott explains, saturation occurs when you’re down there for simply 60 minutes.
Positive, there’s a comparatively secure “indoor” surroundings to retreat to—just like being inside a spaceship—however in both location, “If one thing goes flawed, you and your crew have to determine the way to get right into a secure configuration, together with accounting to your crewmates.”
Every part about it’s a excellent analog for house, she goes on: The way you talk, act along with your crew and mission management crew, dwell in cramped quarters, use specialised gear, and the best way you might be required to take care of emergency conditions. It’s simply that in a single case you’re beneath stress surrounded by water and the opposite you’re coping with the lethal vacuum of house.

“It’s the last word parallel of the intense surroundings of house,” Stott says, much more so than different coaching astronauts should endure, together with chilly climate and wilderness survival. However in these conditions, she explains, that assist is just a satellite tv for pc cellphone name away. Deep in house or deep underwater, all of it comes all the way down to self-survival, working as a crew, and understanding the way to handle stress in a high-stakes surroundings. “It’s a completely diff psychological expertise,” Stott provides.
Diver certification isn’t required for these dreaming of turning into astronauts, both professionally or as house vacationers. However Stott says in the event you don’t have dive expertise already and your astronaut software is accepted, you’ll get that certification and expertise quickly.
For many who desire to go in ready or wish to expertise what house looks like right here on Earth, Stott is greater than thrilled to make an introduction. In truth, she simply accomplished her second Island Astronaut Camp in partnership with PADI and COMO Maalifushi within the Maldives. Collectively, youngsters snorkeled, constructed bottle rockets, designed house fits, and discovered the significance of appearing like a crew member, not only a passenger, whether or not they head to house, keep firmly rooted on terra firma, or discover underwater environments. It’s only one manner she helps join the house curious with the house severe by way of her House for A Higher World and House for Artwork Basis.
“It’s fairly cool that we will spend time undersea—residing and dealing in inside house—to finest put together for what it’s going to be wish to dwell and work in outer house,” Stott says. So if you wish to expertise what it’s like in house, head underwater.
