How far out have humans traveled in space?

Answer 1

Outer space is an extremely hostile place. If you were to step outside a spacecraft, such as the International Space Station,or on a world with little or no atmosphere such as the moon or Mars without the protection of a space suit,, then the following things would happen:

• You would lose consciousness because there is no oxygen. This could occur in as little as 15 seconds.
• Because there is no air pressure to keep your blood and body fluids in a liquid state, the fluids would "boil." Because the "boiling process" would cause them to lose heat energy rapidly, the fluids would freeze before they were evaporated totally (There is a cool display in San Francisco's science museum, The Exploratorium, that demonstrates this principle!). This process could take from 30 seconds to 1 minute. So, it was possible for astronaut David Bowman in "2001: A Space Odyssey" to survive when he ejected from the space pod into the airlock without a space helmet and repressurized the airlock within 30 seconds.
• Your tissues (skin, heart, and other internal organs) would expand because of the boiling fluids. However, they would not "explode" as depicted in some Science Fiction movies, such as "Total Recall."
• You would face extreme changes in temperature: sunlight - 248 degrees Fahrenheit or 120 degrees Celsius; shade - minus 148 degrees Fahrenheit or minus 100 degrees Celsius
• You would be exposed to various types of radiation (cosmic rays) or charged particles emitted from the sun (solar wind).
• You could be hit by small particles of dust or rock that move at high speeds (micrometeoroids) or orbiting debris from satellites or spacecraft.

You would die quickly because of the first three things listed, probably in less than one minute. 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. So to protect astronauts, NASA has developed elaborate spacesuits.
Below is another link, which I think is more informative. The article is long and therefore too large to simply paste. It is highly interesting though so I encourage you to read it if you are truly interested in learning more about the subject.

Space exposure ---- Take a look at this, very interesting information.

Answer 2

The furthest humans have traveled in space (away from the earth) is to the moon

and around its far side. But there have been a number of people that have spent a

long time in space going round the Earth. Look in the link I will place below for more

detailed information.

Just for comparison, that farthest trip into space by a human is about 0.0095 of the

distance to the nearest planet (Venus), and about 0.0026 of the distance to the sun.

Answer 3

The farthest distance from the Earth that any human beings have been propelled

was scored by the Apollo astronauts who orbited the moon, putting them roughly

2,200 miles farther from us than those who merely landed on the moon's nearer

side ... a total of maybe 241,000 miles from Earth, or about 1/4 of one percent

of the distance to the sun, and about 7/10 of one percent of the shortest distance

between the Earth and Mars at any time during the past 5,000 years, and almost ...

not quite but almost ... one whole percent of the closest that Venus ever is to Earth.

Really moving on out there, into the trackless void where no man has gone before !

Answer 4

90 percent of the work of space travel is getting into space to begin with; once you're there, there are few limits to how far you can go. The biggest obstacle is taking your cozy Earth environment - your life support system - with you, and keeping it working.

Make that environment large enough, and it can take care of itself without much technology. That would require a fairly large habitat, with plants to provide oxygen and remove the CO2, and to provide food and recycle wastes. But it works here on Earth; it will work there as well.

Answer 5

Very quickly.

Eventually...

Your eyes and mouth would get frosty right away though. The temperature in space is near absolute zero, however there isn't anything to transfer your heat away.

That answer would work if the question were: "how quickly would you freeze if you rolled around butt-naked on the moon?"

Answer 6

The farthest any human has traveled into space is actually unknown, because a Russian cosmonaut was lost in space . The furthest record has been the Apollo 13 mission from the American astronauts when they flew around the moon and back. Human kind has made machines that travel to different planets for us though, like the mars rovers.

Answer 7

No one actually knows. We can't even estimate how much "space" there is up there in the universe.

Answer 8

How long do you think anyone can survive without air?

Answer 9

if is constantly on 8 hours if u mean as till it burns up 12 mabey 13 hours

Answer 10

The furthest humans have travelled in space is a little past the moon but they were in the moon's gravitational pull. The furthest that humans have landed is on the moon.
