Titan Lake In-situ Sampling Propelled Explorer (TALISE) is a proposed space probe which would land in Ligeia Mare, the second largest lake on Saturn's moon Titan. TALISE would navigate across the lake for six months to one year. If this mission is approved, it will analyze liquid and take scientific measurements while it navigates to the coast in the northern region of Titan. It is also planned in the mission to study the surrounding terrain of Ligeia Mare.
A comparable mission concept was NASA's Titan Mare Explorer, which, unlike TALISE, would not have had its own propulsion system.
