Social media-savvy astronaut Scott Kelly took to Twitter over the weekend to answer questions about life in space. The astronaut is spending a year on the International Space Station so NASA can study the effects of long-term space travel on the human body.

Kelly who lives in Houston when he’s not orbiting the Earth, admits he misses his hometown and his favorite planet (the Earth!).

He also responded to question from the President of the United States (or whoever runs his Twitter account).

1. Most importantly, he explained about what happens to pee in space after being asked where fresh water comes from:

2. Kelly said it's one of the most time-consuming tasks he does every day.

3. Nobody ever said space-life was glamorous. Another user asked him "how do you wash or iron your clothes in space?"

4. And space showers don't sound nearly as refreshing.

5. Kelly also explained the danger of a gooey space sneeze.

6. There's no smartphones in space phones. But Apple products do exist in orbit. 

7. If Kelly could be anywhere in the universe right now, it'd be in the Bayou City.

8. Even guys floating above the Earth look up to J.J. Watt. The astronaut said he still follows sports from the space station.

9. He also manages to stay in shape.

10. In space, no one can hear you freak out, Mr. President.

11. Kelly gave us a glimpse of his quaint living quarters.

12. He spends his downtime in space the same way many of us do on Earth (except with more urine processing)
