  • Space suits can be punctured by pieces of space junk, as even the shuttle itself has been damaged slightly. Tiny flecks of paint or rock particles have the same ability to damage as a bullet does. Spacewalking astronauts have found their gloves punctured on at least two occasions. Once, the object that pierced it remained in place and kept it sealed, and the other time the puncture extended only through two of the five glove layers. Should the hole cause depressurization of the suit, an astronaut would die.

OK, If you went into space without a suit very little would happen at first. Space is very cold but there is no air or matter to make you feel cold so it would take a long time for you to cool off. Its not like going into a freezer because there's no heat conduction.

You would only get very minor decompression since at most only one atmosphere would be the change of pressure.

One atmosphere is a small pressure change so your lungs won't explode or blood boil or anything like that, you could hold air in your lungs without difficulty.

The only pressing problem you would face would be lack of breathing air, so if you have one breath in your lungs then you better get somewhere with air real fast. Most people can hold their breath for maybe two minutes if they have to.

There would be no protection from the sun's x- and uv radiation so you'll want to get out of the sun in a hurry. A few seconds exposure won't hurt you but several minutes might.

In the movie 2001 they had a scene where the astronaut had to get back into the ship by leaving his pod and being without a suit in space. It was a believeable scene and the effects of air pressure were well replicated in the film.

they wouldn't breath and die. then (relative to the position of the astronaut)if the corpse float up in space it will burn to ashes and if it floats down in space it will freeze and the ice block will always be there.

You would ultimately suffocate due to lack of oxygen, and die a terrible death.

Well, he would die once his oxygen supply ran out.

What would happen if you went to Mars without a spacesuit?

You would likely die.


What would happen to an astronaut without a spacesuit?

They would quickly die of asphyxiation due to the lack of air and the astronauts blood would boil because there is very little pressure in space so this would lower the boiling point of your blood causing it to boil quicker at a lower temperature this would also contribute to killing the astronaut.


Can you sneeze on the moon?

An astronaut would be in a sealed spacesuit when out of the spacecraft and standing on the Moon's surface. So he or she would be able to sneeze (within the confines of the spacesuit).


What would happen to an astronaut on Mars without a space suit?

He/she would suffocate and/or freeze.


What would an astronaut need to wear on Pluto?

An astronaut landing on Pluto would need to wear a spacesuit that is not much different from those used now for spacewalks in orbit of Earth.


What would happen if a flying piece of debris ripped a hole in a spacesuit?

The spacesuit would depressurize, leaving the person inside the spacesuit (if there is one) no oxygen to breathe, leading to their death.


If an astronaut was stranded in space but was hovering above the earths atmosphere would there be any way to make it back alive?

The astronaut would need to be rescued. There is no way to get back to Earth from orbit in only a spacesuit.


Is mars safe for humans?

Not without spacesuits, just like the moon. If a person were to walk around Mars, they would freeze to death and die from lack of oxygen. With a spacesuit, an astronaut could walk around on Mars, just like they could walk around the surface of the moon wearing a spacesuit.


If an astronaut has a mass of 900kg in his spacesuit what would the weight be on Ganymede?

Ganymede has 14.6 percent of the gravity of earth. Therefore, if an astronaut weighing 900 kg were on Ganymede, his gravitational pull would be the equivalent of 13.14 kg.
