Dragonfly

Dragonfly is a future NASA space mission to Saturn's moon, Titan, essentially a rotorcraft drone, to explore Titan's surface and atmosphere. Unlike Mars's very thin atmosphere, Titan's is denser than Earth's, making dependence on rotorcraft flight reasonable. Current plans are for a 2028 launch and a 2034 arrival, for 3.3 years of science data collection (with hopes of 10 years). Proposed instruments:

• DraMS - mass spectrometer.
• DraGNS - gamma-ray and neutron spectrometer.
• DraGMet - geophysics and meteorology package.
• DragonCam - camera suite.

For simplicity, the mission includes no orbiter, in part because the drone is able to move to/from positions suitable for communicating with Earth. Power will be provided by an MMRTG. NASA accepted the plan in 2019 as its fourth New Frontiers mission, New Frontiers 4 aka NF4.

An unrelated Dragonfly is the ground telescope, Dragonfly Telephoto Array.
