    (Preprint) AAS 18-416 PRELIMINARY INTERPLANETARY MISSION DESIGN AND NAVIGATION FOR THE DRAGONFLY NEW FRONTIERS MISSION CONCEPT Christopher J. Scott,∗ Martin T. Ozimek,∗ Douglas S. Adams,y Ralph D. Lorenz,z Shyam Bhaskaran,x Rodica Ionasescu,{ Mark Jesick,{ and Frank E. Laipert{ Dragonfly is one of two mission concepts selected in December 2017 to advance into Phase A of NASA’s New Frontiers competition. Dragonfly would address the Ocean Worlds mis- sion theme by investigating Titan’s habitability and prebiotic chemistry and searching for evidence of chemical biosignatures of past (or extant) life. A rotorcraft lander, Dragonfly would capitalize on Titan’s dense atmosphere to enable mobility and sample materials from a variety of geologic settings. This paper describes Dragonfly’s baseline mission design giv- ing a complete picture of the inherent tradespace and outlines the design process from launch to atmospheric entry. INTRODUCTION Hosting the moons Titan and Enceladus, the Saturnian system contains at least two unique destinations that have been classified as ocean worlds. Titan, the second largest moon in the solar system behind Ganymede and the only planetary satellite with a significant atmosphere, is larger than the planet Mercury at 5,150 km (3,200 miles) in diameter. Its atmosphere, approximately 10 times the column mass of Earth’s, is composed of 95% nitrogen, 5% methane, 0.1% hydrogen along with trace amounts of organics.1 Titan’s atmosphere may resemble that of the Earth before biological processes began modifying its composition. Similar to the hydrological cycle on Earth, Titan’s methane evaporates into clouds, rains, and flows over the surface to fill lakes and seas, and subsequently evaporates back into the atmosphere.

    P LANETARY S CIENCE I NSTITUTE NEWSLETTER SPRING 2006 Vol. 7, No. 1 Comets: Visitors from the Early Solar System by Beatrice Mueller This is a great time to be a cometary scientist. We have had three successful spacecraft encounters in the past few years: Deep Space 1 flew by comet 19P/Borrelly in September 2001; Stardust flew through the dust coma of comet 81P/Wild 2 col- lecting samples in January, 2004, and delivering them success- fully to Earth in January, 2006; and, most recently, Deep Impact (the mission, not the movie) hit comet 9P/Tempel 1 in July, 2005. We have also had two “naked-eye” comets in the middle of the nineties: comets Hale-Bopp and Hyakutake, both discov- ered by amateurs. Although I am not on the science teams of these spacecraft mis- sions, I was, and still am, involved with ground-based support observations doing additional scientific research. Only a few specific, but important, science questions can be answered at the time of the actual short-lived spacecraft flybys and much impor- tant research is accomplished long after these exciting events. I am working currently on the rotation state of comet 10P/ Tempel 2. Ignacio Ferrin and I (Mueller & Ferrin 1996, Icarus) observed this comet in 1994 and compared the derived rotation period with a previous pass and found a small change in the rota- Raw CCD R-filter image of the main component of comet tion period. Numerical simulations by Nalin Samarasinha (PSI & 73P/Schwassmann-Wachmann 3 (small white object). Note the National Optical Astronomy Observatory [NOAO]) show the extension and fuzziness of the comet and the narrow tail.

Abstract Titan is one of the most dynamic moons in the solar system. It is smaller than Earth and much colder, yet Titan is eerily similar to Earth, with rivers, rain, and seas, as well as sand seas that wrap around the equator. However, the rivers are made of hydrocarbons rather than water and the sand made of organics rather rock. We can use Titan’s impact craters to study how these processes modify the surface by comparing the craters depths, diameters and rim heights of Titan’s craters with fresh craters. Therefore, we have used the complete data set from NASA’s Cassini mission to update Titan’s crater population finding 30 new craters (90 total).

  • Titan Ripe for Drone Invasion 5 May 2017, by Matt Williams
    Titan ripe for drone invasion 5 May 2017, by Matt Williams again in late March at the 48th Lunar and Planetary Science Conference in The Woodlands, Texas. Such a mission, as Turtle explained to Universe Today via email, is both timely and necessary. Not only would it build on many recent developments in robotic explorers (such as the Curiosity rover and the Cassini orbiter); but on Titan, there is simply no shortage of opportunities for scientific research. As she put it: "Titan's an ocean world with a unique twist, which is the rich and complex organic chemistry occurring in its atmosphere and on its surface. This combination A proposed eight-bladed drone (aka. "dragonfly") could makes Titan a particularly good target for studying be ideally suited for exploring Saturn's moon Titan in the planetary habitability. One of the big questions coming decades. Credit: APL/Michael Carroll about the development of life is how chemical interactions led to biological processes. Titan's been doing experiments in prebiotic chemistry for millions of years – timescales that are impossible to With its dense and hydrocarbon-rich atmosphere, reproduce in the lab – and the results of these Titan has been a subject of interest for many experiments are there to be collected." decades. And with the success of the Cassini- Huygens mission, which began exploring Saturn Their proposal is based in part on previous Decadal and its system of moons back in 2004, there are Surveys, such as the Campaign Strategy Working many proposals on the table for follow-up missions Group (CSWG) on Prebiotic Chemistry in the Outer that would explore the surface of Titan and its Solar System.
