Yaaay Congratulations!!!! Can't wait to see what cool science you're up to next! 🙌🙌🙌

Yeah I personally think the Venus debate is proof that it would be good to move away from gases as biosignatures. To make any meaningful conclusion, ground sampling will be necessary.

Likely no biosignature method is ever going to stand by itself, but right now there is a lot of great research going into very useful directions that go further than just depending on a specific molecule.

The H2O/ O2 argument was connected to habitability for other planets...very earth centric!
