Dissolved nitrogen and nitrogen narcosis
Divers (and others) call the compressed air cylinders used by divers tank(s) or SCUBA tank(s).
Oxygen needs to be compressed in a diver's tank to increase the amount of oxygen that can be stored in the tank. Compressing the gas allows divers to carry enough oxygen to sustain them while underwater for a longer period of time without the tank becoming too large and unwieldy.
The space shuttle system is made up of three main components: the orbiter, the external tank, and the solid rocket boosters. These components work together to launch and maneuver the shuttle in space.
Because they have a air tank to help them breath.

Divers typically get their air from a tank filled with compressed air, which they carry on their backs. This tank is connected to a regulator that controls the flow of air, allowing divers to breathe comfortably underwater. In some cases, divers may use alternative gas mixtures, such as nitrox or trimix, to extend their dive time or enhance safety. Surface-supplied diving systems are another option, providing air through a hose from a support vessel.
The front tank is the main tank and the rear tank is the auxiliary tank.
they need to know how long they can be underwater, and how deep they can go with the air in the tank.
A space shuttle typically consists of three main components: the orbiter, the solid rocket boosters, and the external fuel tank. The orbiter is where the crew stays and the payload is carried. The solid rocket boosters provide additional thrust during liftoff, while the external fuel tank supplies fuel for the main engines.

They don't breathe normally on their own.They have to use pressure regulators to breathe naturally, overcoming the extreme pressure deep underwater.A snorkel and oxygen tank help the divers breathe when they are underwater.
