ABSTRACT active geologic processes including scarps and outflows [1]. Its surface undergoes continuous modification, Coming years will bring several comet rendezvous with visible change during the years between two missions. The Rosetta spacecraft arrives at Comet flybys. The EPOXI flyby of comet Hartley 2 shows 67P/Churyumov–Gerasimenko in 2014. Subsequent skyscraper-size spires, flat featureless plains that outgas rendezvous might include a mission such as the H O, regions of rough and mottled texture, bands of proposed Comet Hopper with multiple surface landings, 2 various shapes, and diverse surface albedo. Comets’ as well as Comet Nucleus Sample Return (CNSR) and active areas range from 10-90%, changing over time Coma Rendezvous and Sample Return (CRSR). These and distance to the sun. They manifest as both localized encounters will begin to shed light on a population that, jets and diffuse regions (Figure 1). Still more exotic, despite several previous flybys, remains mysterious and recently discovered “active asteroids” suggest that poorly understood. -

Comparative Saturn-Versus-Jupiter Tether Operation
Journal of Geophysical Research: Space Physics Comparative Saturn-Versus-Jupiter Tether Operation J. R. Sanmartin1 ©, J. Pelaez1 ©, and I. Carrera-Calvo1 Abstract Saturn, Uranus, and Neptune, among the four Giant Outer planets, have magnetic field B about 20 times weaker than Jupiter. This could suggest, in principle, that planetary capture and operation using tethers, which involve B effects twice, might be much less effective at Saturn, in particular, than at Jupiter. It was recently found, however, that the very high Jovian B itself strongly limits conditions for tether use, maximum captured spacecraft-to-tether mass ratio only reaching to about 3.5. Further, it is here shown that planetary parameters and low magnetic field might make tether operation at Saturn more effective than at Jupiter. Operation analysis involves electron plasma density in a limited radial range, about 1-1.5 times Saturn radius, and is weakly requiring as regards density modeling. 1. Introduction All Giant Outer planets have magnetic field B and corotating plasma, allowing nonconventional exploration. Electrodynamic tethers, which are thermodynamic (dissipative) in character, can 1. provide propellantless drag both for deorbiting spacecraft in Low Earth Orbit at end of mission and for planetary spacecraft capture and operation down the gravitational well, and 2. generate accompanying, useful electrical power, or store it to later invert tether current (Sanmartin et al., 1993; Sanmartin & Estes, 1999). At Jupiter, tethers could be effective because its field B is high (Sanmartin et al., 2008). Tethers would allow a variety of science applications (Sanchez-Torres & Sanmartin, 2011). The Saturn field is 20 times smaller, however, and tether operation involves field B twice, which makes that thermodynamic character manifest: 1. -

Every Delta Science Reader has three main sections: Think About . , People in Science, and Did You Know? Be sure to preview the reader Overview Chart on page 4, the reader itself, and the teaching suggestions on the following pages. This information will help you determine how to plan your schedule for reader selections and activity sessions. Reading for information is a key literacy skill. Use the following ideas as appropriate for your teaching style and the needs of your students. The After Reading section includes an assessment and writing links. OVERVIEW Students will: discover facts about the Solar System In the Delta Science Reader Solar System, students take a tour of the Sun and the explore the planets and other objects in the planets. Other space objects such as dwarf Solar System planets, comets, asteroids, and meteoroids discuss the function of a table of contents, are explored. Students read about the headings, and a glossary rotation and revolution of the planets and interpret photographs and graphics to the causes of night and day, seasonal answer questions changes, and the phases of the Moon.

LAST CALL for the DAS Dinner Meeting Tuesday, May17th
Vol. 56, No. 5, May, 2011 Next Meeting – May 17th, 2011 at 6:00 PM ~ Annual Dinner Meeting at the Hilton Wilmington/Christiana ~ See Pages 4 & 5 for full Details on this Event Celebrating the DAS Amateur Astronomer of the Year FROM THE PRESIDENT ! Bill Hanagan To start off, I’d like to thank Bill McKibben for his LAST CALL for the presentation at the April meeting on the Ancient Astronomy of Machu Picchu and Greg Lee for his presentation on DAS Dinner Meeting “What’s Up in the Sky”. If you missed the April meeting, you also missed my presentation on the sizing, positioning, and th surface quality of Newtonian secondary mirrors. Tuesday, May 17 Our May meeting is the annual “dinner” meeting of the DAS and it will be held on Tuesday, May 17 at the Christiana You’ll need to call Treasurer McKibben Hilton, the same location as last year. Social hour begins at at this late hour for Reservations. 6:00 P.M. followed by dinner at 7:00 P.M. After dinner, we’ll view a short video of time lapse astrophotos followed by the Andrew K. Johnston presentation of the Amateur Astronomer of the Year Award. We’ll conclude the evening with a talk titled “Navigating across from the the Solar System” by Mr. Andrew K. Johnston from the National Smithsonian Air and Space Museum. Mr. Johnston is the co-author of the “Smithsonian Atlas of Space Exploration” and his talk will give National Air & us a look at the history and technology of solar system explora- tion. -
(Preprint) AAS 18-416 PRELIMINARY INTERPLANETARY MISSION
(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. -
