Spacelab wasn't a location in the sky; it was a reusable laboratory module that was flown aboard the Space Shuttle. It wasn't a permanent fixture in space like a space station.

Here's what you need to know:

* Spacelab was transported to and from space inside the Space Shuttle's cargo bay.

* It was used for various scientific experiments and research.

* The last Spacelab mission was in 1998.

So, if you're looking for Spacelab in the sky, you won't find it! It was a part of the Space Shuttle program and has been retired for over two decades.
