So..a pebble can travel 3 times as a bullet. Which is 3000ft/sec=case bullet is 1000ft/sec?

1) Will the pebble be equally effective as a hand grenade in space?





2) How often for the International space station having to repair the damages cause by a single small rock traveling 3000ft/sec and explode like a hand grenade does?





Questiom #1 Compares to:


shuttle


satitlite


Space station


rocket


another rock





BOOM! SUKKA LUKA!!So..a pebble can travel 3 times as a bullet. Which is 3000ft/sec=case bullet is 1000ft/sec?
Sorry, but I don't know how often orbital stations have to fix punctures. Hardly ever is my guess. The chances of a pebble-sized meteor hitting a station are pretty small, although micropunctures (and radiation for that matter) are the biggest danger. These small particles are much smaller than a pebble. These are practically grains of sand. And they move much faster than 3Kft/sec. More like 7 miles/sec or 14 miles/sec., depending on at what angle they hit the space station or satellite. At that velocity, they pack quite a punch. When you see a meteorite (a falling star), that bright one-second blaze across the sky is usually the size of a grain of sand. Some are bigger, of course, and some even manage to hit the ground.So..a pebble can travel 3 times as a bullet. Which is 3000ft/sec=case bullet is 1000ft/sec?
In the early days of the shuttle program one of the orbiters was hit by a fleck of paint at very high velocity. Two objects in directly opposing orbits could theoretically collide at up to ~16000 meters/sec. (35000mph)The shuttle had a crater dug half way through the outer layer of its windshield, and that is very tough glass indeed.
