Neat new science about Pluto's subsurface ocean.
This makes me want to see a Pluto lander/rover mission. It would be interesting if we can find life precursors or maybe even fossils in the water ice mountains surrounding Sputnik Planitia. I would think that exploring structures like that with more Mars rover-like equipment would be better from planetary protection perspective than the various drilling or submersible missions that have been proposed for moons like Europa or Enceladus.
