In the second report from the 2011 Planetary Lake Lander Expedition, members of the PLL science team begin their exploration of the Chilean lake, Laguna Lo Encañado (rough translation: lagoon in a canyon). Unlike their primary research site (Laguna Negra), Laguna Lo Encañado is opaque, sea-green in color, and lies at the end of a long valley containing significant wetlands.

The Planetary Lake Lander (PLL) team has traveled to remote Laguna Negra in the central Andes of Chile to test technologies that could one day be used to explore the lakes of Titan. The project is led by Principal Investigator Nathalie Cabrol of the NASA Ames Research Center and the SETI Institute, and is funded by the NASA Astrobiology Science and Technology for Exploring Planets (ASTEP) program.
