NASA’s next mission will be either to Titan or a comet

NASA’s next mission will go where some spacecraft have gone before. The two finalists in the agency’s New Frontier selection process will return to either Saturn’s moon Titan or comet 67P/Churyumov-Gerasimenko, NASA announced in a press teleconference on December 20.

The Dragonfly Mission seeks to fly a drone-like craft to Saturn’s largest moon in 2025 that would then land in 2034. NASA’s Cassini-Huygens mission showed that Titan has lakes and rivers of liquid ethane and methane, and could harbour some form of life.

“We can test how far prebiotic chemistry has progressed in an environment that we know has the ingredients for life,” said lead investigator Elizabeth Turtle of the Johns Hopkins Applied Physics Laboratory in Laurel, Md.

 

The other finalist is the Comet Astrobiology Exploration Sample Return (CAESAR) mission, which aims to launch a spacecraft before the end of 2025 to collect a 100-gram sample from the surface of comet 67P, and return it to Earth in 2038.

Rosetta’s mapping work “dramatically improves the chances of success for a very difficult activity, which is grabbing a piece of a comet,” said lead investigator Steven Squyres of Cornell University.

Each project will receive funding to further develop the mission concepts. In July 2019, NASA will announce which mission will be flying off into space.

Comet 67P was mapped by the European Space Agency’s Rosetta Spacecraft (ESA)
