If there are more people trying to fill the Project Hail Mary void, please go listen to Ask Your Father.
It might not be the same, but its a human and a not-quite-human stuck in space, on a mission they might not be able to return from, and instead of a teacher, the main character is a father (whose kids sends adorable radio messages up to their dad)
Just thought the project hail mary crowd might appreciate the recommendation :)
Also, it's a finished show, with just 9 episodes, so it's a compact little listen
