Is Star Atlas playable?

Excuse me, could you clarify something for me? I've been hearing a lot about Star Atlas lately, and I'm curious if it's actually playable at this point? I've seen some previews and teasers, but I'm not sure if it's a fully-fledged game that people can dive into and enjoy, or if it's still in the early stages of development. Could you provide me with some insight into the current state of Star Atlas and whether or not it's playable for the average user? Thank you for your time and assistance.
