Misha and I will collect various types of data for studies on ourselves, which will take a significant amount of our time. Because Mark and I are identical twins, I’m also taking part in an extensive study comparing the two of us throughout the year, down to the genetic level. The International Space Station is a world-class orbiting laboratory, and in addition to the human studies of which I am one of the main subjects, I will also spend a lot of my time this year working on other experiments, like fluid physics, botany, combustion, and Earth observation.
When I talk about the International Space Station to audiences, I always share with them the importance of the science being done there. But to me, it’s just as important that the station is serving as a foothold for our species in space. From there, we can learn more about how to push out farther into the cosmos. The costs are high, as are the risks.
On my last flight to the space station, a mission of 159 days, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained and shrank the walls of my heart. More troubling, I experienced problems with my vision, as many other astronauts have. I have been exposed to more than thirty times the radiation of a person on Earth, equivalent to about ten chest X-rays every day. This exposure will increase my risk of a fatal cancer for the rest of my life. None of this compares, though, to the most troubling risk: that something bad could happen to someone I love while I’m in space with no way for me to come home.
Looking out the window at the strange landscape of Baikonur, I realize that for all the time I’ve spent here, weeks in fact, I have never really seen the town itself. I’ve only been to the designated spaces where I have official business: the hangars where the engineers and technicians prepare our spacecraft and rocket for flight; the windowless fluorescent-lit rooms where we get into our Sokol pressure suits; the building where our instructors, interpreters, doctors, cooks, management people, and other support staff stay; and the nearby building, affectionately called Saddam’s Palace by Americans, where we stay. This opulent residence was built to accommodate the head of the Russian space agency and his staff and guests, and he allows the crews to use it while we’re here. It’s a nicer place than the other facility, and far nicer than the austere crew quarters housed in an office building where shuttle astronauts used to spend quarantine at the Kennedy Space Center in Florida. Saddam’s Palace has crystal chandeliers, marble floors, and a four-room suite for each of us, complete with Jacuzzi tubs. The building also has a banya, or Russian sauna, with a cold pool to jump into afterward. Early in our two-week quarantine I go out to the banya to find a naked Misha beating on a naked Gennady with birch branches. The first time I saw this scene I was a bit taken aback, but once I experienced the banya myself, followed by a dip in a freezing cold pool of water and a homemade Russian beer, I completely understood the appeal.
Saddam’s Palace also has an elaborate dining room with pressed white tablecloths, fine china, and a flat-screen TV on the wall that constantly plays old Russian movies the cosmonauts seem to love. The Russian food is good, but for Americans it can start to get old after a while—borscht at nearly every meal, meat and potatoes, other kinds of meat and potatoes, everything covered with tons of dill.
“Gennady,” I say while we are eating dinner a few days into our stay. “What’s with all the dill?”
“What do you mean?” he asks.
“You guys put dill on everything. Some of this food might actually be good if it weren’t covered in dill.”
“Ah, okay, I understand,” Gennady says, nodding, his signature smile starting to emerge. “It’s from when the Russian diet consisted mostly of potatoes, cabbage, and vodka. Dill gets rid of farts.”
Later I google it. It’s true. As it happens, getting rid of gas is a worthwhile goal before being sealed into a small tin can together for many hours, so I stop complaining about the dill.

THE DAY AFTER we arrive in Baikonur we have the first “fit check.” This is our opportunity to get inside the Soyuz capsule while it’s still in the hangar and not yet attached to the rocket that will launch us into space. In the cavernous hangar known as Building 254 we pull on our Sokol suits—always an awkward process. The only entrance into the suits is in the chest, so we have to slide our lower bodies into the chest hole, then struggle to fit our arms into the sleeves while blindly pulling the neck ring up over our heads. I often come away from this procedure with scratches on my scalp. Not having hair is a disadvantage here. The chest opening is then sealed through a disconcertingly low-tech process of gathering the edges of the fabric together and securing them with elastic bands. The first time I was introduced to this system I couldn’t believe those rubber bands were all that was meant to protect us from space. Once I got to the space station, I learned the Russians use the exact same rubber bands to seal their garbage bags in space. In one sense I find this comical; in another way I respect the efficiency of the Russian philosophy on technology. If it works, why change it?
The Sokol suit was designed as a rescue suit, which means that its only function is to save us in case of a fire or depressurization in the Soyuz. It’s different from the spacesuit I will wear during spacewalks later in my mission; that suit will be much sturdier and more functional, a little spaceship in its own right. The Sokol suit serves the same purpose as the orange NASA-designed pressure suit I used to wear to fly on the space shuttle. NASA introduced that suit only after the Challenger disaster of 1986; before that, shuttle astronauts wore simple cloth flight suits, as the Russians did before a depressurization accident killed three cosmonauts in 1971. Since then, cosmonauts (and any astronauts to join them in the Soyuz) have worn the Sokol suits. In a weird way, we are surrounded by the evidence of tragedies, too-late fixes that might have saved the astronauts and cosmonauts who took the same risks we are taking and lost.
Today is like a dress rehearsal: we suit up, perform leak checks, then get strapped into our custom-made seats, built from plaster molds taken of our bodies. This is not for our comfort, which is not a particularly high priority for the Russians, but for safety and to save space—no sense building more seat than is strictly necessary. The custom-molded seats will cradle our spines and absorb some of the impact on the hard return to Earth a year after we depart.
