By trading wheels for helicopter blades, NASA is upping its game for the Dragonfly mission, a flying machine intended to explore Titan, an icy moon of Saturn.
The team has started assembling the honeycomb panels for the aircraft’s main body, completed a series of drop tests on the parachute system, and demonstrated that its compact chemistry lab can pick out tiny amounts of target molecules in test samples.
This NASA robot, expected to launch as early as 2028, is no space orbiter. Dragonfly will be an SUV-size, eight-rotor aircraft, designed specifically to navigate the hazy orange skies of Titan, a world larger than the planet Mercury. It will explore the alien landscape much like NASA’s fleet of rovers, except Dragonfly will have a much faster way of getting from Point A to B. In the words of Back to the Future‘s Doc Brown: “Roads? Where we’re going, we don’t need roads.”
Titan, about 886 million miles from Earth, is the only moon in the solar system with a substantial atmosphere. But Titan’s air is thick — about 1.5 times the pressure at Earth’s sea level and roughly three times as dense, said Charles Malespin, who leads the team that built the hardware for analyzing Titan’s samples. Because it is so cold in this alien world, gases like methane become liquids, and the atmosphere turns into a heavy blanket. Meanwhile, the moon has just one-seventh Earth’s gravity.
