Watkins (Clegg) Campus Box 1169 Phone: 864-680-4838 1 Brookings Dr. E-Mail: [email protected] Saint Louis, MO 63130 http://ryanclegg.webs.com Research Summary My research uses photometric analysis of Lunar Reconnaissance Orbiter Narrow Angle Camera images of the lunar surface to study surface features, specifically spacecraft landing sites, silicic volcanic areas, lunar swirls, exposures of pure anorthosite, and pyroclastic deposits. I determined the relationship between spacecraft mass and thrust and the area of soil that will be disturbed, with applications to future missions. I use photometric modeling and Apollo soil data to place compositional constraints on regions of non-mare volcanism on the Moon, and I take spectral measurements of the reflectance of lunar soils to use as ground truth for remote sensing data.

  • Exploring the Moon and Mars: Choices for the Nation
    Exploring the Moon and Mars: Choices for the Nation July 1991 OTA-ISC-502 NTIS order #PB91-220046 Recommended Citation: U.S. Congress, Office of Technology AssessmenT Exploring the Moon andMars: Choices for the Nation, OTA-ISC-502 (Washington, DC: U.S. Government Printing Office, July 1991). For sale by the Superintendent of Documents U.S. Government Printing 0ffice, Washington, DC 20402-9325 (order form can be found in the back of this report) Foreword The United States has always been at the forefront of exploring the planets. U.S. space- craft have now journeyed near every planet in the solar system but Pluto, the most distant one. Its probes have also landed on the Moon and Mars. Magellan, the most recent of U.S. interplan- etary voyagers, has been returning thought-provoking, high-resolution radar images of the sur- face of Venus. Scientifically, the prospect of returning to the Moon and exploring Mars in greater detail is an exciting one. President George Bush’s proposal to establish a permanent lunar base and to send human crews to explore Mars is ambitious and would engage both scientists and engi- neers in challenging tasks. Yet it also raises a host of issues regarding the appropriate mix of humans and machines, timeliness, and costs of space exploration. This Nation faces a sobering variety of economic, environmental, and technological challenges over the next few decades, all of which will make major demands on the Federal budget and other national assets. Within this context, Congress will have to decide the appropriate pace and direction for the President’s space exploration proposal.

San Francisco 7:00 pm Doors Open 7:30 pm Announcements 8:00 pm Speaker SFAA’s General Meetings take place on the 3 rd Wednesday of each month (except January) Dr. Jennifer Heldmann Space Science Division, NASA Ames Research Center LUNAR IMPACT: NASA'S LCROSS MISSION Join planetary research scientist Jennifer Heldmann from the Space Sciences Division of NASA Ames Research Center for a presentation on Lunar Impact: NASA’s LCROSS Mission. Heldmann will give an engaging summary of NASA’s current mission to explore the permanently shadowed regions of the lunar poles. With NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS), research scientists are able to investigate and analyze data collected from these previously unexplored regions of the Moon. Dr. Heldmann served on the Science Team, Payload Team, and as the Observation Campaign Coordinator for NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) mission to study the permanently shadowed regions of the lunar poles. The science goals of LCROSS included investigating the presence or absence of water on the Moon as well as furthering our understanding of other species trapped in these regions. Dr. Heldmann received a Bachelor’s degree in Astrogeophysics from Colgate University, a Master’s degree in Space Studies and a minor in Geology from the University of North Dakota, and a doctorate degree in Planetary Science from the University of Colorado. Dr. Heldmann is currently a Research Scientist in the Division of Space Sciences and Astrobiology at NASA Ames Research Center in California.

  • Next Meeting Thursday, February 20Th the LADEE Mission by Rick Kang
    Io – February 2014 p.1 IO - February 2014 Issue 2014-02 PO Box 7264 Eugene Astronomical Society Annual Club Dues $25 Springfield, OR 97475 President: Sam Pitts - 688-7330 www.eugeneastro.org Secretary: Jerry Oltion - 343-4758 Additional Board members: EAS is a proud member of: Jacob Strandlien, Tony Dandurand, John Loper. Next Meeting Thursday, February 20th The LADEE Mission by Rick Kang The LADEE (pronounced “laddie” like lassie) Mission is one of a series of spacecraft launched over the past several years by NASA to further explore our Moon. LADEE stands for Lunar Atmosphere and Dust Environment Explorer, and is currently orbiting the Moon, beginning to collect data on the composi- tion of the weak lunar atmosphere, including a dust component. I’ll show a Powerpoint Presentation furnished by LADEE’s Education/Public Outreach officer, Dr. Brian Day, based at the Ames facility in California, that he made available to the Astronomical Society of the Pacific for one of their recent webcasts. The presentation covers data about lunar water and the lunar atmosphere. Much of Dr. Day’s interest is in the low density of the lunar atmosphere; technically this condition is called a surface boundary exo- sphere. This means that unlike much of Earth’s atmosphere, where air molecules are typically jostled by frequent collisions with one another, in an exosphere the low density effectively prevents collisions, and the air molecules/particles travel in ballistic trajectories. This condition exists from the very surface of the Moon upward, thus “surface boundary.” We suspect that many of the Solar System’s smaller objects (low gravity), like asteroids and moons, also have surface boundary exospheres.

  • Lunar Cartography: Progress in the 2000S and Prospects for the 2010S
    LUNAR CARTOGRAPHY: PROGRESS IN THE 2000S AND PROSPECTS FOR THE 2010S R. L. Kirk*, B. A. Archinal, L. R. Gaddis, M. R. Rosiek Astrogeology Science Center, U.S. Geological Survey, Flagstaff, Arizona 86001 USA (rkirk, barchinal, lgaddis, mrosiek)@usgs.gov Commission IV, WG IV/7 KEY WORDS: Extra-terrestrial, extraterrestrial, planetary, international, databases, cartography, geodesy, mapping ABSTRACT: The first decade of the 21st century has seen a new golden age of lunar exploration, with more missions than in any decade since the 1960’s and many more nations participating than at any time in the past. We have previously summarized the history of lunar mapping and described the lunar missions planned for the 2000’s (Kirk et al. 2006; 2007; 2008). Here we report on the outcome of lunar missions of this decade, the data gathered, the cartographic work accomplished and what remains to be done, and what is known about mission plans for the coming decade. Four missions of lunar orbital reconnaissance were launched and completed in the decade 2001–2010: SMART-1 (European Space Agency), SELENE/Kaguya (Japan), Chang’e-1 (China), and Chandrayaan-1 (India). In addition, the Lunar Reconnaissance Orbiter or LRO (USA) is in an extended mission, and Chang’e-2 (China) operated in lunar orbit in 2010-2011. All these spacecraft have incorporated cameras capable of providing basic data for lunar mapping, and all but SMART-1 carried laser altimeters. Chang’e-1, Chang’e-2, Kaguya, and Chandrayaan-1 carried pushbroom stereo cameras intended for stereo mapping at scales of 120, 10, 10, and 5 m/pixel respectively, and LRO is obtaining global stereo imaging at 100 m/pixel with its Wide Angle Camera (WAC) and hundreds of targeted stereo observations at 0.5 m/pixel with its Narrow Angle Camera (NAC).
