Today was a very exciting day. We conducted our first simulated EVA. We kept it simple and useful. It involved only two EVA crew members: Frank Schubert and Sam Burbank. Frank is the builder of the Hab and he is serving as our onboard “spacecraft” systems engineer. Sam Burbank is a filmmaker and our project videographer, but as a former owner of a motorcycle shop, he is also a competent mechanic and is doubling as ship mechanic.
