why do space missions don't crash with flying objects/meteroids while enroute in space ?

Answer 1

Well, all the man-made stuff down to the size of a 3" bolt is tracked. The shuttle and the ISS are routinely manuevering a little higher or lower,depending on the trajectory of 'space junk' being tracked.

The natural stuff - micrometeors, spacesand, whatever - *does* hit the shuttle & space station. Atlantis was hit by something about the size of grain of sand on it's windshield several years ago - melting a small, dime-size area.

Answer 2

The total amount of volume in Space is tremendously vast, and the number of dangerous particles, bits of debris, rocks, comets and asteroids are very, very few in comparison. That does not say that such collisions are not possible. They are just unlikely, which is most fortunate for us. Any space vehicle struck by an object in space would be doomed to certain destruction in a flash. I don't think that there would be any suitable warning or chance for explanatory radio messages home.

Answer 3

Well, they do and they don't. All spacecraft do have collisions with "micrometerorites"--microscopic bits of dust and debris.

However, space is VERY big--and while thare are millions o f bigger rocks--from the size of a pea (or even less) up to giant asteroids tens, even hundreds of miles across--these are actually relatively rare. Between their relative scaricity and the vast regions of space, the chances of a collision are very low. It can happen, of course, but only as a very rare event.

Answer 4

Because there's still a whole lot of empty space out there.

To hear you talk, you infer that astronauts have to dodge "buckshot" every inch of the way through space. It just isn't so.

Answer 5

They do, but mostly they are tiny, going at low speed and in the same direction. Everything has a micrometerioid shield.
