NASA to fund robot missions to comet, Saturn moon
NASA has selected two mission concepts, to return a comet sample to Earth and explore the habitability of Saturn's largest moon Titan, for a $850-million funding. While a mission named CAESAR would return samples from comet 67P that was successfully explored by ESA's Rosetta spacecraft, Dragonfly would explore landing sites on Titan, identified as an ocean world by Cassini spacecraft.
