What would an extra-vehicular activity (EVA) be like on a spacecraft which consists of modules along a (100s of meters long) rotating tether that causes simulated gravity? See for example these slides and pdf for Joe Carroll's ideas about this kind of spacecraft/spacestation.
- Could the astronaut stand and walk on the "roof" of a module?
- Where does the astronaut go if he/she falls off the side of a module?
- What would be easier and more difficult respectively, with rotation than in microgravity?
I'd guess that manual handling of tools would be much more Earth like and thus construction work much more efficient. Maybe large construction projects in LEO and beyond should be performed in rotating artificial gravity?
