Kelly, a graduate of the UT Space Institute, spent a year aboard the International Space Station while his twin brother, Mark, stayed on Earth. UTSI is a part of UT’s Tickle College of Engineering.

The Canadian Broadcasting Corporation reports that Scott Kelly’s body underwent changes at a genetic level, something that had not been anticipated.
