Clayton C. Anderson

2-time ISS astronaut; 6 spacewalks, 30-yrs NASA, Author/Spkr

A small town boy from Ashland, Nebraska, I am honored to have been able to live my dream of becoming a United States Astronaut. “Kicked to the curb” by NASA’s Astronaut Selection process fourteen times, I am proud to be the first (and currently only) astronaut ever from the State of Nebraska! My answers are my own, and do not represent NASA…I don’t always agree with what they say and/or do! I’m also an author… who’da thought?!

I have worked in all the major human space flight programs for NASA for almost three decades.  I have first hand knowledge and experience of many systems that folks might find interesting.  Rather that wait to retire to write my tell-all book I would like to share some of that information with readers on Quora. 

I have spend the majority of my career at the Johnson Space Center in Houston Texas, USA, but started at the Kennedy Space Center in Florida where I participated in over 40 launches of the Space Shuttle.  I was an Environmental and Life Support System engineer so I am most familiar with those system.  Later in the Orbiter Project Office I worked in the Fluid Systems Division which had responsibility for all the fluid systems including hydraulics and main propulsion systems. 

I am presently working on a next generation space suit to replace the current one in use on ISS as well as prepare for future exploration missions beyond low Earth orbit.

I joined Quora to share the wonders of the space program. In addition to space exploration and instructional design, I like to write about movies, comic books, and history.

Former NASA AstronautJust your typical story about a kid who grew up in New Jersey and studied hard, got good grades and somehow became a NASA Astronaut.  Having left NASA in 2011, I now work for Elon Musk at SpaceX where I am the program manager for our Dragon-Falcon 9 crew vehicle – about to return Americans to space on American rockets!
