A new theory suggests that Titan’s majestic dune fields may have come from outer space. Researchers had always assumed that the sand making up Titan’s dunes was locally made, through erosion or condensed from atmospheric hydrocarbons. But researchers from the University of Colorado want to know: Could it have come from comets?

The surface exploration of Saturn’s largest moon, Titan, just got one step closer to reality as NASA’s much-anticipated Dragonfly mission recently received approval from the powers that be to advance to Phase C, which is designated as Final Design and Fabrication, according to NASA’s Systems Engineering Handbook. This comes after the Dragonfly team successfully completed all the requirements for Phase B in March 2023, also known as the Preliminary Design Review or Preliminary Design and Technology Completion in the NASA Systems Engineering Handbook.
