TALISE (Titan Lake In-situ Sampling Propelled Explorer) is a proposed automated boat that would float in a lake called Ligeia Mare on Saturn's moon Titan.
I saw an article that said once it touches down in the lake, TALISE would begin working its way toward the shore of the lake. There are some people who think life could be found on Titan, which is one of the reasons people want to explore it (but also, how cool would it be to send a boat through space?), do they think that life might be easier to find closer to shore? Is there another reason they want to move toward shore?
