what happens with the debry that is a result of spaceships?

Question

Have you ever noticed that when there is a pointless launch, what happens with all the rockets that somehow split off the main rocket?

Answer 1

Debry? Do you mean debris?
The launch trajectory of ships (from the US) is over the ocean, so any booster engines or other materials that are ejected land in the ocean.
Not sure what you mean by "pointless launch".

Answer 2

In most cases, the rocket engines (boosters) are split off from the main vehicle body and fall to earth to be recovered later via parachute deployment by Naval and Air Force ships and aircraft. Nothing re-useable and valuable is wasted.

If, on the other hand something blows up, or is triggered to blow up, nothing but a lot of DEBRIS (notice spelling) results. All of that material eventually falls back to Earth and is incinerated during re-entry into the Earth's atmosphere. Some debris stays in orbit for quite a while before dropping down into the atmosphere.

Answer 3

As you might have feared, a lot of stays up in space, being a nuisance. Some of it falls down and hits things. There is a group which actually watches and maps it the big pieces because they could be a danger to flights.
