Blindsight reminded me a lot of Lem's Fiasko[1] which I read as a teenager in the 80's.

It's worth to read all of his 'first contact' themed ones. They all use a slightly different lens on the same theme:

Eden, Solaris, The Invincible & His Master's Voice

Also, The Europa Report film, where astronauts search for life in the liquid ocean beneath ice on one of Jupiter's moons.
