A Titan Mission Could Refuel on Site and Return a Sample to Earth

This decade promises to be an exciting time for space exploration! Already, the Perseverance rover landed on Mars and began conducting science operations. Later this year, the next-generation James Webb Space Telescope, the Double Asteroid Redirection Test (DART), and Lucy spacecraft (the first mission to Jupiter’s Trojan asteroids) will launch. Before the decade is out, missions will also be sent to Europa and Titan to extend the search for signs of life in our Solar System.

Currently, NASA’s plan for exploring Titan (Saturn’s largest moon) is to send a nuclear-powered quadcopter to explore the atmosphere and surface (named Dragonfly). However, another possibility that was presented this year as part of the NASA Innovative Advanced Concepts (NIAC) program is to send a sample-return vehicle with Dragonfly that could fuel up using liquid methane harvested from Titan’s surface.
