I’m Mike Massimino, former NASA Astronaut and author of Spaceman. AMA!
I have to head out for a Facebook Live over at Space.com (check it out on their Facebook!), but thanks for your questions! You can read more in Spaceman, it's out everywhere today.
Hey Reddit! I’m Mike Massimino. I was a NASA astronaut from 1996-2014 and flew in space twice: STS-109 on space shuttle Columbia in March 2002 and STS-125 on space shuttle Atlantis in May 2009 – the final two Hubble Space Telescope servicing missions. I was the first human to tweet from space and the last human to work inside of Hubble, and my crewmates and I set a team record for the most cumulative spacewalking time in a single space shuttle mission. If you’re a fan of The Big Bang Theory, you may have seen me playing myself on the show.
I write about my unlikely journey to become an astronaut and my crazy stories from space in my new book Spaceman. You can get it now at the links below. Ask me anything about my time on Earth, my time in space, or my book!
