what is a “launch window” and why can’t they just launch rockets a few hours before or after said window?

I used to love watching shuttle launches, and they would sometimes delay missions a day or two due to weather, even if the rain/snow would be over in a few hours. Why couldn’t they just wait instead of delaying?

This will be quite simplified, but:

The Space Shuttle often went up to reach the ISS. For simplicity’s sake, let’s say that the ISS needs to be directly overhead for the space shuttle to be able to meet up with it (this is broadly true). If the shuttle launches while the ISS is somewhere else (like the other side of the earth) they’ll be orbiting the earth in wildly different places, with no way to reach each other.

I hope this helps!
