OVERVIEW Regular, low-cost Decadal-class science missions to planetary destinations enabled by small high-ΔV spacecraft, like the high-energy Photon, support expanding opportunities for scientists and increase the rate of science return. The high-energy Photon can launch on Electron to precisely target escape asymptotes for planetary small spacecraft missions with payload masses up to ~50 kg without the need for a medium or heavy lift launch vehicle. The high-energy Photon can also launch as a secondary payload with even greater payload masses to deep-space science targets. This paper describes planetary mission concepts connected to science objectives that leverage Rocket Lab’s deep space mission approach. The high-energy Photon can access various planetary science targets of interest including the cislunar environment, Small Bodies, Mars, Venus, and the Outer Planets. Additional planetary small spacecraft missions with focused investigations are recommended, including dedicated small spacecraft missions that do not rely on launch as a secondary payload. 2. HIGH-ENERGY PHOTON Figure 1: The high-energy The high-energy Photon (Figure 1) is a self-sufficient small spacecraft Photon enables small planetary capable of long-duration interplanetary cruise. Its power system is science missions, including Venus probe missions. conventional, using photovoltaic solar arrays and lithium-polymer secondary batteries.

Proto-Micronesian Reconstructions—1
Proto-Micronesian Reconstructions—1 Byron W. Bender, Ward H. Goodenough, Frederick H. Jackson, Jeffrey C. Marck, Kenneth L. Rehg, Ho-min Sohn, Stephen Trussel, and Judith W. Wang1 university of hawai‘i and university of pennsylvania Part 1 presents some 980 reconstructions for Proto-Micronesian, Proto–Central Micronesian, and Proto–Western Micronesian. Part 2 (to appear in volume 42 [2]) gives reconstructions for two additional subgroups within Proto-Micronesian: Proto-Pohnpeic and Proto-Chuukic, and their immediate ancestor, Proto– Pohnpeic-Chuukic. A handful of putative loans are also identi²ed, and a single English ²nder list is provided for all of the reconstructions. INTRODUCTION. Lexical data for a number of Micronesian languages began to be collected systematically in the mid-1960s as part of the development of language lessons for the U.S. Peace Corps and in connection with other Micronesian language projects that followed at the University of Hawai‘i. These data were stored on a main- frame computer using programs then being developed (Hsu and Peters 1984), and eventually dictionaries were published for a number of the languages included in this study (Elbert 1972, Abo et al. 1976, Lee 1976, Sohn and Tawerilmang 1976, Harrison and Albert 1977, Jensen 1977, Rehg and Sohl 1979, Goodenough and Sugita 1980, Jackson and Mark 1991). Comparative work using these data began with Marck 1977, focusing on the group of languages referred to as Nuclear Micronesian. In the next several years, the authors of the current study put the initial data on computer and sub- stantially added to them by directly eliciting information from speakers of Microne- sian languages who were students in the Bilingual Education Project for Micronesia at the University of Hawai‘i. -

NASA Night Sky Network Ten years later Rosetta has now arrived at Comet 67P/Churyumov- Gerasimenko and just successfully made orbit today, 2014 August 6! Unfortunately, global events have foreshadowed this memorable event and news media have largely ignored this impressive space mission. AAC Member photo: The Rosetta comet mission may be the beginning of a story that will tell more about us -- both about our origins and evolution. (Hence, its name "rosetta" for the black basalt stone with inscriptions giving the first clues to deciphering Egyptian hieroglyphics.) Pictures received over past weeks are remarkable with the latest in the past 24 hours showing awesome and incredible detail including views that show the comet is a connected binary object rotating as a unit in 12 hours.

You may have noticed that this newsletter is showing up a little bit later than usual, and it’s for good reason: release of the newsletter will now happen after the monthly business meeting so that we can have a chance to keep everybody up to date on the latest information. Sometimes, this will mean the newsletter shows up a couple of days late. But, the upshot is that you’ll now be able to see what we discussed at the recent business meeting and have time to digest it before our general meeting in case you want to give some feedback. Now that we’re on the new format, business meetings (and the oft neglected Light Pollution Committee Meeting), are going to start being open to all members of the club again by simply joining up in the respective chat rooms the Wednesday before the first Monday of the month—which I encourage people to do, especially if you have some ideas you want to see the club put into action. -
Cosmic Hunt: Variants of a Siberian -– North-American Myth *
THE COSMIC HUNT: VARIANTS OF A SIBERIAN -– NORTH-AMERICAN MYTH * Yuri Berezkin Abstract The mythological motif of the Cosmic Hunt is peculiar to Northern and Cen- tral Eurasia and for the Americas but seems to be absent in other parts of the globe. Two distinct Eurasian versions demonstrate North-American par- allels at the level of minor details which could be explained only by particular historical links between corresponding traditions. The first version (three stars of the handle of the Big Dipper are hunters and the dipper itself is an animal; Alcor is a dog or a cooking pot) connects Siberian (especially Western Siberian) traditions with the North-American West (Salish, Chinook) and East (especially with the Iroquois). The second version (the Orion’s Belt rep- resents three deer, antelopes, mountain sheep or buffaloes; the hunter is Rigel or other star below the Orion's Belt; his arrow has pierced the game and is seen either as Betelgeuze or as the stars of Orion's Head) connects the South-Siberian – Central-Eurasian mythologies with traditions of North- American West – Southwest. Both variants unknown in Northeast Asia and in Alaska probably date to the time of initial settling of the New World. The circum-Arctic variant(s) (hunter or game are associated with Orion or the Pleiades) are represented by neighbouring traditions which form an almost continuous chain from the Lapps to the Polar Inuit. This version could be brought across the American Arctic with the spread of Tule Eskimo. Keywords: comparative, Siberian, Central Asian, American Indian, Eskimo mythology; star names in folk tradition; settling of America The mythological motif of the Cosmic Hunt (F59.2 according to S. -
Skywatchers of Africa and Follow The
A Teacher Resource Guide for For Grades 3 to 8 Children’s Museum of Virginia Lesson Overview The education resource was developed using the 5E model of learning and involves pre-visit activities to ENGAGE student interest, planetarium presentations using simulation software along with hands on activities to EXPLORE and EXPAIN about the nature of constellations and related the constellations to the lore from African societies, an EXTEND/ELABORATE section where they further develop the concepts of their visit as well as the EVALUATE section to allow a check of student mastery. The delivery of the EXPLORE and EXPLAIN sections can be tailored to your particular needs and may include one of two possible planetarium shows as well as a mini lesson on selected constellations. Standards of Learning Virginia Standards History 3.1, 3.4, 8.3, 8.4 Science Various point 1 bullets for grades 3 - 6 National Standards Geography How to use maps and other geographic representations, tools and technologies to acquire, process and report information. How to use mental maps to organize information about people, place and environments. Science As a result of their activities in grades k – 4, all students should develop an understanding of: o Objects in the sky o Changes in Earth and sky Essential Questions What are constellations and what methods are best to observe them? How do the constellations you can see vary from one spot to another on Earth? How do the accepted constellations of today differ from those created by early African civilizations? Instructional Objectives Students will observe the planetarium sky using familiar patters to navigate other constellations; view the southern skies above Africa to illustrate how the groups of constellations varies with latitude; learn about several of the dominant cultures of native Africa and about the names for the constellations; and recognize that the constellations which they invent can be just as useful as the ancient Greek, Roman or African constellations. -

New Horizons Gets a Boost from Jupiter
New Horizons Gets a Boost From Jupiter — Fran Bagenal, University of Colorado New Horizons Principle Investigator Alan Stern says the objective of the Jupiter fl yby (aside from getting a gravitational boost out to Pluto) is to check out and learn about the spacecraft so that when we get to Pluto we can learn about Pluto and not worry about the spacecraft. Wise words, I will agree, but we are all hoping for some fun science at Jupiter too. We have to remember that New Horizons is tiny compared to Cassini (a piano instead of a school bus), and the instruments are optimized for observing faint, miniscule Pluto out beyond 30 AU, rather than bright, giant Jupiter at 5.2 AU. But with some ingenuity, there should be some excellent images of Jupiter’s clouds, the rings, and the large Galilean moons. New Horizons is carrying several instruments and two cameras: The long-range, telephoto Long Range Reconnaissance Orbiter (LORRI) takes high- resolution images, while Ralph takes images at multiple wavelengths to determine compositions of surface materials. Alice is an ultraviolet spectrometer Lthat is designed to detect Pluto’s tenuous atmosphere via stellar occultation. At Jupiter, Alice will sometimes look at ultraviolet emissions from hot gases (e.g., Jupiter’s aurora), and at other times will look back at the Sun through atmospheric gases to determine composition, pressure, and temperature of upper regions of Jupiter’s atmosphere as well as the tenuous atmospheres of the satellites. The particle detectors, Solar Wind Around Pluto (SWAP) (low The New Horizon spacecraft is on approach to Jupiter, and will energy) and Pluto Energetic Particle Spectrometer use the giant planet’s gravity to increase speed and reduce the Science Investigation (PEPSSI) (high energy), will time to Pluto. -

Plath’s readership will then be familiar with Plath’s natal chart, information neither Plath nor Hughes left in writing. In our century, the only excuse for attention to astrology is that there appears to be some- do “govern a life,” or whether Plath or Hughes 1 Taking the subject about as seriously as Hughes did, and using, as he did, Western astrology’s classic geocentric method, we begin with the facts of 1 Ted Hughes in the poem “A Dream,” p. 118 in Birthday Let- 15 SPECIAL FEATURE - was “psychic” or intuitive, requiring a knack, but that is never true: Chart interpretation and prognostication are skills and arts anyone can acquire through instruction, readings, case stud- ies, and practice; one might even add to the lit- erature by becoming a scholar.4 Astrologers use Plath’s natal Sun was in the zodiac sign Scorpio case studies as jurists use precedents.
