People survive in space by wearing space suits. The space suits provide them with oxygen and surround them with air. Also, They stay in space ships that keep them safe by keeping them surrounded by air under pressure.

∙ 12y agoWe haven't discovered any conclusive evidence that shows aliens exist to begin with. However, scientists have been finding small organisms like bacteria in extremely hostile environments here on Earth such as boiling water in springs near a volcano or in highly toxic radioactive waste. These organisms have evolved over billions of years to adapt to those extremes and survive there.
If we do find life soon, it will very likely be microscopic organisms like bacteria. We can't tell how they survive until we actually discover some form of life off Earth.
If alien life is anything like Earth's life (and there's no reason to think it would be even close), they might survive the same way bacteria do here on earth: by finding a source of energy, convert that energy through their Biology into food, excrete waste matter, and reproduce.
But we may just as easily discover their biology is so completely different from ours we can't even dream what they're like. Only time will tell.

Why do you send out space probes insted of actual space flights with astronauts?
NASA occasionally sends out space probes instead of humans because astronauts could not survive on some of the places that space probes are sent to.
How does the astronauts survive in the outer space?
The spacecraft that astronauts go up in, have their own life support systems which regulate conditions to keep the spacecraft hospitable.
What are the astronauts' achievements?
The early Soyuz and Mercury astronauts found out that man could survive in space. That meant eating, sleeping, going to the bathroom, and even manipulating the spacecraft in space. Astronauts on both sides of the Space Race found out in the mid 1960s that man could work outside the spacecraft with proper restraints. Gemini astronauts performed the first rendezvous and docking in space, an important milestone in reaching the moon. The Apollo astronauts achieved the first manned flight to the moon, showing that man can survive a trip through the Van Allen Belt. Apollo 11 showed man could land on the moon and return safely to the earth. Astronauts on Soviet space stations, Mir, Skylab, and the Space Shuttle showed that man can survive in space for months at a time. They also built the International Space Station, and continue making advances in all scientific areas.
How much oxegyn can a astronaut suit contain?
Oxygen (O2) is necessary to the respiration and the survival of astronauts in the near vacuum of space. Astronauts does not have the breathable atmosphere on Earth in space. The space suit protects them from the lethal cold and vacuum of space by keeping him in temperature controlled and pressurized environment.
Why do astronauts use space pen?
astronauts use space pen because as there is 0gravity in space ink will not fall on the paper
How do astronauts survive in outer space?
with space suits
What did the astronauts of Apollo 13 do to survive on the space shuttle?
The Apollo 13 astronauts were not on the space shuttle.
What do astronauts need to survive in space?
food, water, shelter
What did the astronauts do to survive on the space shuttle?
Ensure all systems are working correctly.
How do astronauts survive in space when they are actually up there?
They survive by bringing all they need with them - food, air, water... etc.
Why do you send out space probes insted of actual space flights with astronauts?
NASA occasionally sends out space probes instead of humans because astronauts could not survive on some of the places that space probes are sent to.
How do astronauts survive in space outside there shuttle?
Astronauts ONLY survive inside their space suits. Basically the space suit acts like a small space craft by controlling the temperature, pressure, and supplying air for the person inside. Without it the astronaut would be dead within a few seconds.
How long can astronauts survive in space?
No one knows, but typically astronauts do not stay in space for more than 1 year. Otherwise, the zero gravity will degrade their bones and muscles
How do astronauts survive living in space?
they have air masks and have a speacil clothing :) they have a slepp wido
How did the crew of Apollo 13 survive in space after the accident?
The astronauts of Apollo 13 , used the lunar module to survive after the accident.
