Once exposed to a vacuum, there would be maybe 10 seconds or so of useful consciousness.
After passing out, it would take a few minutes for vital tissues (brain & heart) to be irreversibly damaged from hypoxia.
If you go into space without a spacesuit, you would experience a rapid drop in pressure, causing your bodily fluids to boil and leading to decompression sickness. You would also be exposed to harmful levels of radiation and extreme temperatures, resulting in rapid hypothermia or hyperthermia. Ultimately, you would not survive for long due to the hostile conditions of space.
A human would not be able to survive on Mars without a spacesuit and life support systems. The lack of breathable air, extreme temperatures, and absence of liquid water make it inhospitable for human life.
Astronauts can survive in space for a limited amount of time without protection due to the lack of oxygen and extreme temperatures. In the vacuum of space, they would quickly lose consciousness due to lack of oxygen, but the exact time frame can vary based on the individual. With the appropriate gear and protection, such as a spacesuit or spacecraft, astronauts can survive for extended periods of time in space.
It can take 2 hours to put on a space suit.
People can typically survive in the vacuum of space for about 15 seconds before losing consciousness due to hypoxia, as the body is deprived of oxygen. After that, bodily functions would begin to fail, and irreversible damage could occur within a few minutes due to factors like decompression or exposure to extreme temperatures. However, death would likely occur within 1 to 2 minutes if no rescue is provided.
until your air runs out or forever
If you go into space without a spacesuit, you would experience a rapid drop in pressure, causing your bodily fluids to boil and leading to decompression sickness. You would also be exposed to harmful levels of radiation and extreme temperatures, resulting in rapid hypothermia or hyperthermia. Ultimately, you would not survive for long due to the hostile conditions of space.
as long as you are wearing a spacesuit
If a human being exposed to open space without spacesuit, due to pressure difference he cannot breathe & within minutes he will die.
Of coarse they would, we humans can survive weeks without food as long as there is an intake of water.
Not long
You need energy to survive, so you cannot survive without energy.
It would depend on the occasion...is it a wedding, a football match or a barbeque?
Not long with oxygen, about two seconds without it.
It theory, it is possible. But would you want to? Most people can survive a long time without food, but a much shorter time without water.
The ability to store water and the ability to survive long time without getting water.
Without any form of protection about 30 seconds of pure agony.
