Why would people living inside a nebula go into space?
Assuming a sci-fi style nebula, like the thick clouds seen in Star Trek, extending several light years and hosting star systems inside, one of which gave rise to intelligent life up to current human intelligence level.
The homeworld of that lifeform has a few natural satellites that are small asteroids captured eons ago. Big enough to be seen as moving lights in the sky, not big enough to be able to discern any feature, other planets of their system are hardly able to be seen due to the luminosity and colors of the nebula. The nebula is a thick flesh-colored cloud of gas.
Would that civilization have any incentive to go out into space and why?
EDIT: Please do not comment about how unrealistic that kind of nebula is and the problems it would create would it exist in real life. That is not the question I am asking and you will notice the lack of a 'hard-science' tag. Thank you very much.

A similar story has been written (a mini epic really over many generations) that has a civilisation living inside space that was doomed to become uninhabitable due to excessive cosmic junk in the vicinity.
Scientists in your Nebula Planet may correctly surmise that conditions will change too fast for the species to evolve or survive and decide on a global multi generational migration plan.
The book in question is John Brunner's Crucible of time and is one of his less dystopian books and I very much enjoyed each reading of it.
