    The vacuum of space is a hostile environment,if a human being were to step outside of a spacecraft without protection, he or she would experience any number of terrible physical damages. The lack of air pressure would induce the blood and other liquids in body to boil, which would also cause the expansion of the body's tissues.Temperature would also be a factor, with the astronaut possibly freezing or burning depending upon his or her location in relation to the sun. In addition, he or she would be exposed to radiation, which can cause damage to any matter.

    The vacuum of space is a hostile environment. First, a human being without spacesuit will experience enormous pains because of terrible physical dameges caused by lacking oxygen and filled with radiation. Second, the weightlessness of space forces astronauts to work in pair, tied to the soacecraft to aviod floating away.Besides, the lack of gravity blocks the blood circulate and face awollen. Astronaurs may also suffer from headaches and dizziness, as well as many other mental illnesses.

    1. The capsule or spacesuit is breached by space debris, causing oxygen to leak 2. The capsule malfunctions, leaving the astronauts unable to sustain life and waiting for rescue. . . . . 3. During launch and return, failure of a launch vehicle or spacecraft, failure to launch or return (spacecraft disintegrated, exploded, parachute not opened, failed to launch to intended orbit, significant deviation from re-entry...)4. Do Not rule out being attacked by high-grade life in the univers

Besids, The lack of gravity blocks the blood circulate and causes the veins of neck and face swollen. Astronaurs may also suffer from headaches and dizziness, as well as many other mental illnesses.

    There’s always the constant danger of floating away into space due to the lack of gravity .Liquids within the body are no longer affected by gravity, the pressure of the heart and blood vessels often pushes the blood to the astronaut’s body and heart. This causes the veins of the neck and face to stand out more than usual. The astronauts may also suffer from headaches. Astronauts can also suffer from illnesses such as “space sickness” or ‘space adaptation syndrome’.

        The vacuum of space is a hostile environment, because it lacks oxygen and filled with radiation, which may cause a human being's terrible physical damages due to stepping outside of a spacecraft without protaction. And it's easily to become unconscious within seconds. Then, the lack of air pressure may induce the blood and other liquids to boil, causing the tissues' expansion. Also, the location in relation to the sun will influence the astronauts' body temperature. In addtion, astonauts may be exposed to radiation, which can cause damage to living tissues in large amounts.

    the astronouts would suffer from putty face or space sickness.

    the vacuum of space is a hostile environment . The sealed capsule or spacesuit is broken by space garbage, resulting in lacking oxygen .

    In the process of launch and return, the failure of launch vehicle or spacecraft leads to the failure of launch or return.

    Can't rule out being attacked by high-level life in the universe.

    Temperature is also a factor, and the astronaut may freeze or burn, depending on his or her position towards the sun.
