NASA\u2019s Dragonfly Mission Sets Sights on Titan\u2019s Mysteries<\/h1>\n<\/div>\n<\/div>\n<\/div>\n

When it descends through the thick golden haze on Saturn\u2019s moon Titan, NASA\u2019s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan\u2019s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas.\u00a0<\/p>\n

Artist\u2019s concept of NASA\u2019s Dragonfly on the surface of Saturn\u2019s moon Titan. The car-sized rotorcraft will be equipped to characterize the habitability of Titan\u2019s environment, investigate the progression of prebiotic chemistry in an environment where carbon-rich material and liquid water may have mixed for an extended period, and even search for chemical indications of whether water-based or hydrocarbon-based life once existed on Titan.<\/div>\n

But not everything is as familiar as it seems. At minus 292 degrees Fahrenheit, the dune sands aren\u2019t silicate grains but organic material. The rivers, lakes and seas hold liquid methane and ethane, not water. Titan is a frigid world laden with organic molecules.\u00a0<\/p>\n

Yet Dragonfly, a car-sized rotorcraft set to launch no earlier than 2028, will explore this frigid world to potentially answer one of science\u2019s biggest questions: How did life begin?<\/p>\n

Seeking answers about life in a place where it likely can\u2019t survive seems odd. But that\u2019s precisely the point.<\/p>\n

\u201cDragonfly isn\u2019t a mission to detect life \u2014 it\u2019s a mission to investigate the chemistry that came before biology here on Earth,\u201d said Zibi Turtle, principal investigator for Dragonfly and a planetary scientist at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. \u201cOn Titan, we can explore the chemical processes that may have led to life on Earth without life complicating the picture.\u201d<\/p>\n

On Earth, life has reshaped nearly everything, burying its chemical forebears beneath eons of evolution. Even today\u2019s microbes rely on a slew of reactions to keep squirming.<\/p>\n

\u201cYou need to have gone from simple to complex chemistry before jumping to biology, but we don\u2019t know all the steps,\u201d Turtle said. \u201cTitan allows us to uncover some of them.\u201d<\/p>\n

Titan is an untouched chemical laboratory where all the ingredients for known life \u2014 organics, liquid water and an energy source \u2014 have interacted in the past. What Dragonfly uncovers will illuminate a past since erased on Earth and refine our understanding of habitability and whether the chemistry that sparked life here is a universal rule \u2014 or a wonderous cosmic fluke.\u00a0<\/p>\n

Before NASA\u2019s\u00a0Cassini-Huygens mission<\/a>, researchers didn\u2019t know just how rich Titan is in organic molecules. The mission\u2019s data, combined with laboratory experiments, revealed a molecular smorgasbord \u2014 ethane, propane, acetylene, acetone, vinyl cyanide, benzene, cyanogen, and more.\u00a0<\/p>\n

These molecules fall to the surface, forming thick deposits on Titan\u2019s ice bedrock. Scientists believe life-related chemistry could start there \u2014 if given some liquid water, such as from an asteroid impact.<\/p>\n

Enter Selk crater, a 50-mile-wide impact site. It\u2019s a key Dragonfly destination, not only because it\u2019s covered in organics, but because it may have had liquid water for an extended time.<\/p>\n

Selk crater, a 50-mile-wide impact site highlighted on this infrared image of Titan, is a key Dragonfly destination. Landing near Selk, Dragonfly will explore various sites, analyzing the surface chemistry to investigate the frozen remains of what could have been prebiotic chemistry in action.<\/div>\n

The impact that formed Selk melted the icy bedrock, creating a temporary pool that could have remained liquid for hundreds to thousands of years under an insulating ice layer, like winter ponds on Earth. If a natural antifreeze like ammonia were mixed in, the pool could have remained unfrozen even longer, blending water with organics and the impactor\u2019s silicon, phosphorus, sulfur and iron to form a primordial soup.<\/p>\n

\u201cIt\u2019s essentially a long-running chemical experiment,\u201d said Sarah H\u00f6rst, an atmospheric chemist at Johns Hopkins University and co-investigator on Dragonfly\u2019s science team. \u201cThat\u2019s why Titan is exciting. It\u2019s a natural version of our origin-of-life experiments \u2014 except it\u2019s been running much longer and on a planetary scale.\u201d<\/p>\n

For decades, scientists have simulated Earth\u2019s early conditions, mixing water with simple organics to create a \u201cprebiotic soup\u201d and jumpstarting reactions with an electrical shock. The problem is time. Most tests last weeks, maybe months or years.<\/p>\n

The melt pools at Selk crater, however, possibly lasted tens of thousands of years. Still shorter than the hundreds of millions of years it took life to emerge on Earth, but potentially enough time for critical chemistry to occur.\u00a0<\/p>\n

\u201cWe don\u2019t know if Earth life took so long because conditions had to stabilize or because the chemistry itself needed time,\u201d H\u00f6rst said. \u201cBut models show that if you toss Titan\u2019s organics into water, tens of thousands of years is plenty of time for chemistry to happen.\u201d<\/p>\n

Dragonfly will test that theory. Landing near Selk, it will fly from site to site, analyzing the surface chemistry to investigate the frozen remains of what could have been prebiotic chemistry in action.\u00a0<\/p>\n

Morgan Cable, a research scientist at NASA\u2019s Jet Propulsion Laboratory in Southern California and co-investigator on Dragonfly, is particularly excited about the Dragonfly Mass Spectrometer (DraMS) instrument. Developed by NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, with a key subsystem provided by the CNES (Centre National d\u2019Etudes Spatiales), DraMS will search for indicators of complex chemistry.<\/p>\n

\u201cWe\u2019re not looking for exact molecules, but patterns that suggest complexity,\u201d Cable said. On Earth, for example, amino acids \u2014 fundamental to proteins \u2014 appear in specific patterns. A world without life would mainly manufacture the simplest amino acids and form fewer complex ones.\u00a0<\/p>\n

Generally, Titan isn\u2019t regarded as habitable; it\u2019s too cold for the chemistry of life as we know it to occur, and there\u2019s is no liquid water on the surface, where the organics and likely energy sources exist.\u00a0<\/p>\n

Still, scientists have assumed that if a place has life\u2019s ingredients and enough time, complex chemistry \u2014 and eventually life \u2014\u00a0\u00a0should emerge. If Titan proves otherwise, it may mean we\u2019ve misunderstood something about life\u2019s start and it may be rarer than we thought.<\/p>\n

\u201cWe won\u2019t know how easy or difficult it is for these chemical steps to occur if we don\u2019t go, so we need to go and look,\u201d Cable said. \u201cThat\u2019s the fun thing about going to a world like Titan. We\u2019re like detectives with our magnifying glasses, looking at everything and wondering what this is.\u201d\u00a0<\/p>\n

Dragonfly is being designed and built under the direction of the Johns Hopkins Applied Physics Laboratory (APL), which manages the mission for NASA. The team includes key partners at NASA\u2019s Goddard Space Flight Center and NASA\u2019s Jet Propulsion Laboratory. Dragonfly is managed by NASA\u2019s Marshall Space Flight Center in Huntsville, Alabama, for the agency\u2019s Science Mission Directorate at NASA Headquarters in Washington.<\/p>\n
