Exclusive: Space Station Astronauts Talk Loneliness, Missing the Weather and Their Crazy Work Schedule

The first six weeks of Scott Kelly’s marathon year aboard the International Space Station (ISS) haven’t been easy. There was the reacclimation to zero-gravity, the failure of a Russian cargo ship carrying needed supplies, the cancellation of singer Sarah Brightman’s planned visit—to say nothing of the constant, minute-by-minute work schedule that is the stuff of any day aboard the station.

Kelly and astronaut Terry Virts discussed those things and more in one of at least four video chats TIME will conduct with the ISS during our exclusive Year in Space coverage. Phoning the station is not easy. It takes days of planning and at least an hour of sound checks before the uplink is made, and then long delays as questions and answers are relayed back and forth. It makes ordinary conversation a challenge.

Still, even in the 14 minutes the connection lasted—during which the station passed over Canada, the Great Lakes, Minneapolis, Denver, and Southern California—Kelly and Virts were surprisingly open, sharing their feelings about both the camaraderie and the sublime loneliness of being where they are. Kelly especially must be mindful of those feelings as he faces 10 more months of circling the Earth, while his family and friends and everything he knows lie 250 miles below him.

“It’s one thing I think about every single day,” he said.

And then, like any other astronaut, he put that aside and went back to his work.
