Currently the mod can be considered "playable" up until very early space platform, but content still need more polishing.
You can consider the current contents on Nauvis "complete", though they may receive changes in the (distant) future.
I did not modify vanilla recipes beyond this scope yet, so those recipe still exists but I do not guarantee they will be working.
My next updates will be early planet-based science, starting from Gleba. I am currently quite busy IRL and do not have much time on mod development, but the next update is partially complete and I aim to publish on this month.
If you want more updates, or you have any suggestions or ideas on the mod, feel free to join the Discord server.
