NASA’s Perseverance Rover just found Martian rocks rich in minerals tied to microbial life. Exciting—yet without a sample-return and proof of independent origin, this points more to panspermia than proof of life beyond Earth.

NASA’s Perseverance rover found organic molecules in Jezero Crater—once a Martian lakebed. A rock dubbed “Leopard Spots” may even show hints of past microbial life. Proof awaits sample return to Earth.

What if the reason we haven’t heard from ET is because they're waiting for us to do the heavy lifting? Fair trade might mean they’re sending signals too faint for our current tech—read why at johngertz.com/blog.
