Now, when NASA made that announcement, I was hoping for something like this:
"Ultimately the goal is to try to look for biosignatures," Bean said. "This work is another sort of milestone on this road. We're going directly towards that."
Looking at exoplanet atmospheres.
Be even better if they discovered biosignatures on one of these worlds, then managed to focus their instruments in time to pick up on the alien equivalent of Marconi.
