What if there was a spacecraft that could land on an Earth-like world in our solar system and then fly around, picking a new spot every day? It would send back images of lakes, oceans, shorelines, valleys, mountains and mesas.
Bigger than Mercury and with the most complex atmosphere in the solar system, Titan is about to be revealed by a drone. “Dragonfly is such a daring endeavor, like nothing that has ever been done before,”Welcome to Dragonfly, an autonomously operated rotorcraft or octocopter with eight blades that will, from 2034, spend a minimum of two Earth-years exploring the Earth-like world in a series of flights that see it change location every Titan day .
Dragonfly will pick up where Huygens left off. Much of what scientists know about Titan comes from Huygens, which, on Jan. 14, 2005, descended to Titan’s surface over 2 hours 27 minutes, shootingTitan resembles early Earth, but there are many interesting differences between it and present-day Earth. Its atmosphere is 98% nitrogen and 2% methane. Its surface temperature is around -290ºF/-179ºC.
Titan’s atmospheric chemistry is more complex than any other known atmosphere in the solar system. Scientists know that it contains many organic molecules, including hydrocarbons and. Titan's chemistry is thought to change with the seasons. However, because Saturn orbits the sun once every 29 Earth years, each season lasts about seven Earth years.
