How far is it straight up to space?

Question

From Earth to The Space - how far

Answer 1

NASA considers space to start at 400,000 feet

Answer 2

Where space actually begins is somewhat arbitrary, as the other posters have shown.

There is no defined border between space and Earth's atmosphere. While Earth's atmosphere is stratified, the upper bounds of it simply get thinner and thinnner until little distinction can be made between the atmosphere and space, which isn't actually a complete vacuum.

In fact, the Space Shuttle does encounter a very very small amount of drag due to the fact that it does plow through very thin gasses even as high up as it is.

Answer 3

I think over twenty miles because in the 40's or 50's there was this man who wanted to go into space. But there was no knowledge of rocket power so he went on a air balloon straight up. He wore over 10 pieces of sturdy clothing and a gas mask. When he reached up to that height, there was camera footage of the surface of the earth from space. After that he suddenly jumped out of the balloon into a suicidal fall. Amazingly he didnt die, he lived to tell the tale.

Answer 4

It depends on who you're asking. For some test pilots, space begins at 100 kilometers (62.5 miles) up. Others say 80 miles, because that's about the lowest you can get a satellite to orbit the Earth. Others will say 100 miles because that's a nice round number.

The Earth's atmosphere gradually gets thinner and thinner ... there are tiny traces of air out to about 600 miles.

Answer 5

6 miles is considered the beginning of entering space in that competition: the first company to build a plane that could enter space. I can't remember the name of the competition.

Answer 6

About 100 miles or so, depends on the temperature.

Answer 7

10 miles^

Answer 8

Nobody knows that. You can't measure the exact distance.

Answer 9

oh, a simple 80 km from sea level.

Answer 10

You cannot measure that.
