Among various candidate processes, the modeling of oxygen production by hydrogen reduction, ...http://www.ntis.gov/search/product.aspx?ABBR=N20090029911We have performed a joint analysis of the abundance and weak lensing mass estimates of the maxBCG clusters detected using SDSS imaging data. In addition to this data, a prior on the scatter in the mass richness relation derived from demanding consist ...http://www.ntis.gov/search/product.aspx?ABBR=DE2009962101We have previously developed a chemical conversion model of the carbothermal processing of lunar regolith using methane to predict the rate of production of carbon monoxide. In this carbothermal process, gaseous methane is pyrolyzed as it flows over ...http://www.ntis.gov/search/product.aspx?ABBR=N20090029909Autonomous vertical lift aerial vehicles (such as rotorcraft or powered-lift vehicles) hold considerable potential for supporting planetary science and exploration missions. Vertical lift aerial vehicles would have the following advantages/attributes ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028800Fulfillment of the exploration vision will require new cross-mission directorate and multi-technical discipline synergies in order to achieve the necessary long-term sustainability. In part, lessons from the Apollo-era, as well as more recent researc ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028804This catalog is a supplement to the 'Five Millennium Canon of Lunar Eclipses. 'It includes additional information for each eclipse that could not be included in the original publication because of size limits. The data tabulated for each eclipse incl ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028005Since the discovery of periodicity in the solar cycle, the historical record of sunspot number has been carefully examined, attempting to make predictions about the next cycle. Much emphasis has been on predicting the maximum amplitude and length of ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028639One of the important outstanding goals of lunar science is understanding the bombardment history of the Moon and calibrating the impact flux curve for extrapolation to the Earth and other terrestrial planets. The 'terminal lunar cataclysm,' a brief b ...http://www.ntis.gov/search/product.aspx?ABBR=N20090029325The Lunar and Planetary Science group at Marshall provides core capabilities to support the Agency's lunar exploration goals. ILN Anchor Nodes are currently in development by MSFC and APL under the Lunar Quest Program at MSFC. The Science objectives ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028698Several research investigations have examined the challenges and opportunities in the use of small robotic rotorcraft for the exploration of Mars. To date, only vehicles smaller than 150 kg have been studied. This paper proposes to examine the questi ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028805The Crew Exploration Vehicle (CEV) will be exposed to the Micrometeoroid Orbital Debris (MMOD) environment in Low Earth Orbit (LEO) during missions to the International Space Station (ISS) and to the micrometeoroid environment during lunar missions. ...http://www.ntis.gov/search/product.aspx?ABBR=N20090027881NASA's Planetary Science, Division sponsors a competitive program of small spacecraft missions with the goal of performing focused science investigations that complement NASA's larger planetary science explorations at relatively low cost. The goal of ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028789This viewgraph presentation reviews NASA Marshall's effort to sustain space transportation solutions through product lines that include: 1) Propulsion and Transportation Systems; 2) Life Support Systems; and 3) and Earth and Space Science Spacecraft ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028785Field science in extreme terrestrial environments is often difficult and sometimes dangerous. Field seasons are also often short in duration. Robotic field assistants, particularly small highly mobile rotary-wing platforms, have the potential to sign ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028803This paper presents an overview of space environmental testing at NASA Goddard Space Flight Center. The contents include: 1) Solar Absorptance measurements; 2) Emittance measurements; 3) Transient Calorimetric Technique; 4) Electrostatic charge testi ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028004Simulant of lunar dust is needed when researching the lunar environment. However, unlike the true lunar dust, today s simulants do not contain nanophase iron. Two different processes have been developed to fabricate nanophase iron to be used as part ...http://www.ntis.gov/search/product.aspx?ABBR=N20090029913Fourteen-year time series of mesospheric and upper stratospheric temperatures from the Halogen Occultation Experiment (HALOE) are analyzed and reported. The data have been binned according to ten-degree wide latitude zones from 40S to 40N and at 10 a ...http://www.ntis.gov/search/product.aspx?ABBR=N20090027887This poster details a technique of bright point identification that is used to find sources in Chandra X-ray data. The algorithm, part of a program called LEXTRCT, searches for regions of a given size that are above a minimum signal to noise ratio. T ...http://www.ntis.gov/search/product.aspx?ABBR=N20090028640
