Explanation:

Dragonfly Mission is a sample return mission to a comet, and a drone-like rotorcraft that would explore potential landing sites on Saturn?s largest moon, Titan. Dragonfly will be capable of soaring across the skies of Titan and landing intermittently to take scientific measurements, studying the world‘s  mysterious atmosphere and topography while searching for hints of life on the only world other than Earth in our solar system with standing liquid on its surface.

• Part of the Dragonfly mission is to study whether the moon of Saturn could now be, or once was, home to life. Because of the nature of its atmosphere, Titan is a very Earthlike place. Chemically, it is very much like our world‘s primordial past. The surface pressure of Titan is one-and-a-half times the surface pressure of Earth, and the same sorts of interactions between air, land and sea take place. Titan thus has familiar geology.
• Dragonfly was selected as the next mission in NASA's New Frontiers programme of medium-class planetary science missions. It was in competition with the Comet Astrobiology Exploration Sample Return (CAESAR) mission, which would have delivered a sample from a comet to Earth.
