10 Things to Know Before You Go to Outer Space

Commercial space travel will be here in the blink of an eye. And when it does, we will be ready for liftoff. Below, an imagined (abbreviated) cheat sheet for the intrepid and intergalactic traveler's first foray into outer space.

BREAKING THROUGH THE ATMOSPHERE

Where does space begin anyway? About 100 kilometers above sea level (it ends at the upper limit of low Earth orbit). Close enough to phone home and full of photo-ops. There are no black holes, supernovas or gamma ray bursts here — for that, you'll have to go to deep space. For the occasional astronaut, space is less about comet-hopping and more about stargazing while traveling 4.8 miles per second.

ORIENTATION

There are no road signs in space (yet). Get your bearings from the ground up: Continents and clouds occupy the troposphere. Passenger jets fly under the ozone layer in the stratosphere. Shooting stars burn briefly in the mesosphere. Auroras dance and shuttles glide through the thermosphere. Satellites, the International Space Station, and future space resorts, like the , orbit in the outermost exosphere.

With physics at the wheel, you're basically on a carousel ride around Earth, and you're bound to be disoriented doing sixteen laps around it every 24 hours. Up is down in zero gravity. Figure out your position using any three fixed celestial points of reference and some friendly impossible math (there's probably a button on the dashboard for this).

PREPARATION

Exiting the atmosphere isn't easy. You have to do your stretches, eat your veggies, and brace yourself for a complete change of scene. Visit a doctor to ensure you're fit for flight. Train your body for weightlessness 40-feet underwater or in microgravity on a flight. In two years' time, you'll be ready for takeoff.

TAKEOFF AND RE-ENTRY

Odds are you're making it out of the atmosphere. Still, space travel is risky business, so you’ll want to relax and live life to the fullest the week before launch. Have a steak or two. Don't skip dessert. Binge-watch Netflix (you won't get it up there). Get good sleep and report to the day of your flight.

Before you know it, you'll have your eyes to the sky, sounds muffled by the helmet on your hundred-pound spacesuit. You won’t pass out mid-launch — blood won't drain from your brain in your seated position. Endure for nine minutes, and suddenly you're weightless.

If you're not a fan of tradition, you can opt for an air launch, which avoids drag and turbulence in the lower atmosphere by launching from a carrier aircraft. When it’s time for re-entry, don't sweat it: Most Earthbound debris disintegrates from atmospheric heating. Your star cruiser isn't like an unwanted space rock. It has heat shields, parachutes, and an "abandon ship" button. You'll be fine!

WEIGHTLESSNESS

At some point, pouring a glass of celebratory champagne is going to be darn near impossible. On the upside, your decompressed spine will make you look longer and leaner than ever before. A daily space exercise regime (stationary bikes, squats, and cable-machines) is a must for conditioning your body for re-entry.

Cozy digs.

LIFE ON BOARD

With sixteen sunrises a day, it's all about power naps, not REM sleep. Those sudden blinding flashes are cosmic radiation triggering false signals on your retina. when gazing into the infinite void, a general feeling of insignificance is totally normal. But before you curl up in a ball, look back down at Earth for renewed feelings of awe, gratitude, and uncontrollable glee.

LINGO

Control your urge to call Houston every time you have a problem, as that’s only for NASA; yours is a commercial space flight. Sound like a local: “yestersol” is yesterday on Mars; “Malfunction Junction” is Cape Canaveral. Astronauts speak in shorthand, so try abbreviating everything.

DELICACIES

Food is pre-packaged, modified, and unfortunately not available in allergen-free formats. In addition to such classics as freeze-dried ice cream and Tang, you can indulge in out-of-this-world delicacies like space burritos (thanks, Taco Bell), modified kimchi, and tubes of borscht. Fresh fruit and vegetables, delivered on resupply missions, can be enjoyed within two days of delivery before they spoil. Locally sourced fare will soon join the ranks of thermo-stabilized and irradiated on the space menu thanks to and other produce from NASA's in-the-works veggie farm.

STYLE AND ATTIRE

Conditions aboard a space station are controlled at approximately 72 degrees fahrenheit and 60 percent relative humidity, So dress for comfortable California afternoons. Cargo room is limited, but don't skimp on the underwear: You can't do laundry in orbit. Shoes are unnecessary, and outerwear (an orange suit for takeoff and re-entry and a white suit for space strolls) is provided.

READING LIST AND RENTAL CUE

Stephen Hawking's will make you sound like a genius. Chris Hadfield's is inspiring. Kim Stanley Robinson's triggers the imagination. Get dreamy with Jules Verne's or the black and white film it inspired, Georges Méliès' beauty, . Overcome fear with TED Talks from rocket scientist .
