Even before the first human set foot on the lunar surface during NASA's Apollo program … Investigation on impact of life in space on human body could inform potential missions to Mars Twin astronauts Scott Kelly, left, and Mark Kelly. If an astronaut became separated from the space station, how long would he/she survive? You can follow Quora on Twitter, Facebook, and Google+. The main problem as someone has mentioned is muscle and bone loss because of the lack of gravity. Even a few days in space can … Scott spent 11 months at … The movie "Mission to Mars" has a scene that realistically demonstrates what would happen if an astronaut's space suit were to rapidly lose pressure and be exposed to outer space. This question was originally answered on Quora by Leroy Chiao. While there isn't too much risk of being exposed to pathogens, a compromised immune system can result in unwanted autoimmune responses and hypersensitivity. A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a human crew in orbit for an extended period of time. As part of President Bush's "Vision for Space Exploration" plan, the agency announced in 2006 that astronauts would break ground on a lunar base settlement no later than 2020 [source: Johnson ]. It is possible to survive complete depressurization, but not for very long. Either way, your body will remain that way for a long time. That was done by Valeri Polyakov, almost twenty years ago. Radiation exposure can result in cell death or cause mutations resulting in cancers or epigenetic effects. Break out the party hats, because as of today humans have been continuously living on the International Space Station (ISS) for 15 years. This answer has been lightly edited for grammar and clarity. We do our best to provide shielding, but paradoxically, shielding can result in more exposure by what is called secondary radiation. We don't know the answer to that. Stations must have docking ports to allow other spacecraft to dock to transfer crew and supplies. It would seem that mild symptoms of nitrogen narcosis start to appear above 2 bar, so a safe pressure would be around 1.5 - 2 bar, assumed that the internal structure of the space station can support that pressure against vacuum.

How long can humans live in space and what is the worst case scenario for someone who lives too long in space? The astronauts also use wet wipes to wash things. Mostly, these have minor and long-term effects: a slight increase in the risk of cancer in later life, for example. Though space is typically very cold -- most floating objects have a surface temperature of -454.8 degrees Fahrenheit -- a person would not instantly freeze because heat does not transfer away from the body very quickly. The longest contiguous amount of time a human has spent in space is 437 days. Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead. Even in the relatively protected confines of the International Space Station (ISS ... aging over 40 years in a year-long spaceflight," she ... ways that space travel can impact the human body. Without artificial gravity, human growth is stunted and biological functions break down. It would seem that mild symptoms of nitrogen narcosis start to appear above 2 bar, so a safe pressure would be around 1.5 - 2 bar, assumed that the internal structure of the space station can support that pressure against vacuum. There are many reasons to do this. Because our muscles are constantly working against gravity on Earth, those muscles have a lot less work to do in space.
