Person Asks Famous Astronaut What Space Smells Like--And He Actually Answered

Astronaut Scott Kelly is kind of a big deal — he holds the record for the longest U.S. space mission. In 2015, Kelly spent 340 consecutive days in space while his identical twin brother Mark stayed here on Earth. The mission, the first of its kind, allowed scientists to study how space effects the human body. So you'd think when Kelly did a Twitter Q&A, people would want to talk about that mission. Well, you'd be right, but there were also a lot of questions that were less expected, and because of them we now know outer space kind of stinks. 

Let's start with his announcement tweet:

The first question he chose to answer was about his feelings on the flat earth theory, and he brought up a solid point. If the edge of the earth existed, we'd have turned it into a tourist attraction by now. 

Also, ya know, he's seen it. It's round.

Someone asked how he feels about the possibility of life on other planets:

People wanted to know if he appreciated "little" things more:

Isla wanted to know how NASA decided which twin would go to space and which would stay on Earth:

He also answered the age old Star Trek v. Star Wars question, told us what gravity feels like, and talked about his favorite part of Earth to look at. You can see those answers and more on his twitter feed here
