Starting a new project, what are some good questions to ask?

I'm a QA new to this team and we're being tasked with an entire new project starting soon. I've never found myself on this end of the project development cycle before, I've always been on pre-existing projects.

What are some good questions to ask from a QA perspective that will help support the team and our planning? I had a few feeble ones that came to mind but I'm sure some of you have more experience to draw upon. Any help and insight is greatly appreciated!
