Is Star Atlas playable yet?

Excuse me, I've been hearing a lot about Star Atlas lately and I'm quite intrigued. I'm wondering, is the game playable at this moment? I've heard it's a space-themed metaverse with a unique play-to-earn model, and I'm eager to get my hands on it. Is there a specific date when it's going to be officially launched, or is it already available for the public to enjoy? I'd really appreciate any information you can provide.
