Gravitational pull, my dear
Earth's Gravity keeps the atmosphere (AIR, Vapour & Gases) close to it. As we go upwards.. the gravitational pull diminishes- hence the atmosphere becomes 'rarer' until finally it can hold no longer--OUTER SPACE starts here.

To complement what was said before, gravity is holding the atmosphere and in places like mars where the temperature was high enough and the gravity too low, the molecules were sucked and the atmosphere went away with a part of the water.

If the earth were not big enough and dense enough, it would have happened long ago. The gravitational pull of the earth and other big planets is what keeps their atmospheres with them. Moon and smaller bodies have no atmosphere.

In February 2003 the Columbia orbiter incinerated quarter-hour before it changed into through land, with the inability of seven crew. Others were incinerated on the Apollo launchpad. area looks a safer position than the earths surroundings or the launchpad, because no united states has ever admitted dropping someone in area. opposite to an earlier answer, the Russian, Uri Gagarin, back to earth appropriately and grew to grow to be really a star.

That's because the earth's gravity pulls the atmosphere together so that it does not get 'sucked' away.
