Spacesuit

Space suits provide an atmosphere for crew members to use in the event that a ship is deprived of an oxygen-rich, CO₂-poor atmosphere.

At the start of the game, when the ship has no atmosphere, the crew is already wearing space suits. As the player builds the systems necessary for an atmosphere and the ship reaches a sufficient oxygen level, the crew automatically strips off their space suits and leaves them on the floor. If the player sets a space suit storage location, the crew will deposit their suits there instead.

The player can order the crew to put their space suits back on, but the crew will not take oxygen from the suit's tanks unless the atmosphere can't sustain them. Space suits with empty oxygen tanks can be refilled using a space suit port connected to an oxygen supply.
