Скачать или смотреть How Long Can An Astronaut SURVIVE In Their Spacesuit In Open Space?

Astronauts can survive in their spacesuits as long as the oxygen tanks allow them to continue breathing. The two oxygen tanks and the emergency oxygen supply in current EMU suits collectively contain 6.5 to 8 hours (+ 30 minutes) worth of oxygen.

Space exploration movies and books have led us to believe that we would instantly freeze in open space, but that is not the case. While space is indeed cold (depending on where you are), it also lacks any form of matter (definition of vacuum), and the only way left for heat to leave the body is through radiation (conduction and convection require a medium for heat transfer). Given the rate at which heat transfer via radiation occurs, the human body in space would freeze within 12-20 hours.
