Damn! Okay now I gotta drag myself back to the tarantula cage
You don't have to take my word for it. You've always got options, and I tried to think of a few for you. That said, the tarantula cage is one of them if you want to stay with that. Also, it's not a big room, you're not crawling too much.
He'll leave everything except air and additional morphine in the construction section and fight through any pain. You do know how strong morphine is, right? Strife will ignore his arm for a while.
Yeah, I know what morphine is. I loved the stuff - instant nap button. I was thinking it more like the little morphine-shooters combat medic use, but it would be impairing yes. That's why it was an option.
How long can a person be outside on mars without air? Say I wanted to go do something outside of our shelter and then come back in.
The air outside is about -60 Celsius (-75 F), as radioactive as the Van Allen belt, and has less than 1% of the air-pressure, on top of being unbreathable. At that pressure, holding your breath would make your lungs burst, so you'd have to follow the depressure rule of letting your air out and surviving on the oxygen in your blood. Provided you survived the initial shock of stepping outside (temperature mostly), you'd have maybe a minute of two before being turned into frozen jerky. So, just possible.
Does the medical bay have windows?
I'm going to say yes, the medical bay has a few little windows.
How big is the medical bay? Closet, more than one room?
Slightly larger than a bus, about 15x40 feet, divided into one big operating room and two small chambers.
What is a medical station? Fancy scifi medical table with robot arms?
Not too science ficitony, but robotic assisted yes. A hospital bed with all the gizmos and beeping things that you'd expect. And no, it's not mobile.
(What can I assume about the REC-W capsule? Most importantly, does it have an airlock? What size and configuration is it? If I have a little freedom, I could sketch something up... I'm assuming it's inside dimensions are 8 feet tall, 24 feet wide, and 28 feet long, it has at least two adjacent corridors or chambers, it has some kind of internal obstructions (machines in the floor, benches...), and it landed nearly level. It was designed for 0-g and .33-g use, so it has a floor, but also several things installed in the ceiling.)
That's what I was thinking, except you apparently changed your numbers while I was typing this. 12x24x24 feet is the rough floorspace you have. All the tanks, system lines, girders and such make the whole module about 30ft cubed.
