NASA has narrowed its choice for a 2020s deep space planetary mission to two finalists, either a sample return mission to Comet 67P/C-G or a drone that would fly through Titan’s atmosphere.
The sample return mission sounds very doable with today’s technology. The Titan drone mission however is far more intriguing.
Dragonfly is a dual-quadcopter lander that would take advantage of the environment on Titan to fly to multiple locations, some hundreds of miles apart, to sample materials and determine surface composition to investigate Titan’s organic chemistry and habitability, monitor atmospheric and surface conditions, image landforms to investigate geological processes, and perform seismic studies.
If it was up to me and I had unlimited funds, I’d go with Dragonfly. We know far less about the outer solar system, and this mission would be an ideal way to increase that knowledge. It is also far more daring, which carries the risk that the costs to build and launch will rise uncontrollably.

A drone in Titan sounds very much harder than a comet sample return. Hayabusa has already done it, Osiris is doing it in nine months. Flying around in the cold thick atmosphere of Titan ten times further away when at the closest, would be much more exotic. It’s great that NASA is aiming at the outer Solar system in either case, but I bet the comet is what will be chosen. Now they know exactly what to look for, it would be a much more certain success than the Titan drone. And samples keep on giving in the labs.
