Artist Concept of the planned Dragonfly spacecraft

An illustration of the planned Dragonfly spacecraft.

Unable to use solar power under Titan's hazy atmosphere, Dragonfly will use a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG), like the durable Curiosity rover on Mars. Flight, data transmission, and most science operations will be planned during Titan's daytime hours (eight Earth days), giving the rotorcraft plenty of time during the Titan night to recharge.
