Can you survive in space with a scuba suit?

Yes, for a very short time. The principal functions of a spacesuit are to create a pressurized, oxygenated atmosphere for astronauts, and to protect them from ultraviolet rays and extreme temperatures. At most, an astronaut without a suit would last about 15 seconds before losing conciousness from lack of oxygen.

Would scuba suits work in space?

A dive suit might have problems with lubrication – grease evaporation, and vacuum welding of metal parts – unless it was modified. Also, it’s a lot heavier than a space suit which would make it more expensive to launch into orbit. Something like an Atmospheric Diving Suit (aka a JIM Suit) might come close.

How much does an astronaut suit cost?

Narrator: This spacesuit, built in 1974, was reported to cost between $15 million and $22 million. Today, that would be about $150 million. Having not delivered any new mission-ready extravehicular suits since then, NASA is running out of spacesuits. In fact, NASA are down to just four flight-ready EVA suits.

Do spacesuits use rebreathers?

Primary life support subsystem Lithium hydroxide canisters pull carbon dioxide from the air as the astronaut breathes, similar to rebreathers used by scuba divers. Oxygen tanks refresh the circulating pure oxygen air. The suit can run seven hours with a half hour of emergency reserve.

What are deep-sea diving suits?

The specially designed suits provide deep-sea divers with space suit-like protection. Paragon Space Development Corporation used its NASA know-how to create diving suits capable of protecting deep-sea divers from hazardous environments.

Can a space suit be used underwater?

Space suits are air tight (of course) but not really designed for underwater use. By no means. A US EVA space suit is designed to keep IN at most about one third of one atmosphere of pressure differential (about 4-5 psi).

Why do space suits collapse at deep water?

All other diving requires the diver to remain at or near the pressure of the surrounding water. Space suits are fine for this, and are routinely used in this way in training. Space suits will not “collapse” at depth for the same reason any other soft diving suit won’t collapse, it will be filled with air at ambient pressure.

How much pressure does a space suit keep water pressure in?

A US EVA space suit is designed to keep IN at most about one third of one atmosphere of pressure differential (about 4-5 psi). Water increases in pressure at roughly the rate of one armosphere per 10 meters/30 feet — and diving equipment is intended to either equalize that pressure inside and out OR keep the pressure OUT.
