Dr. Sanjay Gupta is a surgeon and the medical correspondent for CNN where his reports are watched by millions around the world. He was also one of the keynote speakers at the 2016 International Space Station R&D Conference in San Diego where he led a discussion with Mark and Scott Kelly, veteran NASA astronauts and subjects of the Twins Study. (Scott spent nearly an entire year in orbit collecting bodily fluid samples and conducting experiments on the space station. Meanwhile, his brother Mark would undergo many of the same tests and collect the same samples so scientists can compare data from genetically identical humans.)

We caught up with Gupta after the talk in San Diego and he told us why he feels the station is such an important resource for science and if he would ever go into space himself.
