NASA had turned it down, but APL could revise and resubmit the proposal, a common practice in space science. In 2011, they had proposed a mission that would land a floating science platform on one of the methane seas in Titan's northern hemisphere. A handful of them met at APL to discuss their options. NASA's list of target worlds included Titan, and that caught the attention of scientists and engineers at the Johns Hopkins Applied Physics Laboratory. The likely deadline for proposals would be April 2017, only 16 months away. In January 2016, NASA issued a community announcement that it would be soliciting proposals for missions to solar system planetary bodies as part of New Frontiers, a program of less expensive missions-under $1 billion each, which counts as less expensive in space exploration. Not on the frozen, uninhabitable surface but perhaps in the subsurface liquid H 2O. There's even the remote but tantalizing possibility that somewhere on Titan, prebiotic has become biotic-that proteins or cellular life already exist. No one can explain how organic matter-that is, carbon-based material-can erode to become sand, but it does on Titan.) The moon's complex prebiotic chemistry-prebiotic as in prior to life-may mirror the conditions on Earth 4 billion years ago, before the emergence of the first terrestrial living organisms. (On Earth, sand comes from erosion of rock. There are possibly volcanoes that spew water and vast fields of dunes sculpted by wind and composed of organic sand. Here it rains liquid methane that collects in rivers, lakes, and seas. Titan has a hydrous silicate rock core that appears to be wrapped in a global subsurface ocean of water under an outer shell made of rock-hard water ice.

Larger in diameter than Mercury, the moon has a nitrogen atmosphere full of complex organic molecules that is four times denser than Earth's.

That's not a scientifically precise observation, but it's apt.

Lorenz came at the problem from a different angle: What about a plutonium-powered helicopter? 'We should be in for a treat,' Lorenz wrote, already anticipating a successful mission. Researchers had already suggested balloons or even small airplanes. Would a land rover be able to move at all? What if there turned out to be a variety of geologic features scattered across the moon? Wouldn't it be great to sample several of them? Titan's dense atmosphere and low gravity would be ideal for aircraft, which could ferry scientific instruments from one site to another all over the moon. At the time, no one knew what they'd find on the moon's surface. Lorenz and other planetary scientists were more ambitious for Titan. The first Mars rover, Sojourner, had covered about 100 meters of the Martian surface in 1997. In July 2000, the British magazine New Scientist published a cover story titled ' Titan Here We Come.' Written by Ralph Lorenz, a planetary scientist at the University of Arizona, the brief article made a case for rocketing a mobile lander to Titan, the largest moon orbiting Saturn.
