EVA

Extravehicular actions (EVA) in unbreatheable space mean that the astronaut is leaving the station. In low-orbit that's the International Space Station (ISS); this applies also to the Moon. Apparently preparation-time is a pain in the arse (PITA). I didn't know that suiting-up took nearly this long. UPDATE 11/11: I actually did know that, a couple years ago. OW MY JOINTS

I have to imagine that, where there's regolith, they'll tack on cleaning costs.

ToughSF is bringing to attention, B. Griffin et al. (2020) SinglePerson Spacecraft. Genesis Engineering are modeling this after single-person pods in submarining. Bezos wanted it for the Orbital Reef but lately it's unclear if that's even going to happen.

I have to ask if astros even need to go outside if they own VR headsets, and the pod can manoeuvre with its own propellant.
