Icarus Robotics cofounders Ethan Barajas and Jamie Palmer spent hours interviewing astronauts about what it was like working in space as they homed in on their startup idea.

If an experiment takes two hours on station, the person continued, the first ninety minutes are spent just moving around cargo and preparing tools.
