Abstract Nighttime Lyman Alpha Mapping Project (LAMP) observations are used to investigate condensed volatiles at the south polar region of Moon. This study incorporates LAMP data from first ∼7 years mission and Diviner annual maximum temperatures search for volatile signatures associated with H 2 O, NH 3 , CO . Other stable potential species, example, SO S, not identifiable ultraviolet ratio‐temperature techniques directly addressed in this study. We confidently detect a ∼20% increase...
Abstract We employ nighttime observations from the Lyman Alpha Mapping Project (LAMP) ultraviolet (UV) spectrograph onboard Lunar Reconnaissance Orbiter to investigate presence of condensed water ice within lunar south pole cold traps. This study incorporates LAMP between 2009 and 2016, which more than doubles number previous Permanently Shadowed Regions (PSRs) studies. In this study, we focus on traps five polar craters: Faustini, Shoemaker, Haworth, Cabeus, Amundsen. An unnamed trap region...
Abstract Data returned from the Cassini–Huygens mission have strengthened Enceladus, a small icy moon of Saturn, as an important target in search for life our solar system. Information gathered Cassini to support this includes presence subsurface liquid water ocean, vapor plumes and ice grains emanating its south polar region, detection essential elements organic material that could potentially life. However, several outstanding questions remain regarding connectivity plume ocean composition...
Abstract Far-ultraviolet (FUV) observations by the Lunar Reconnaissance Orbiter Lyman Alpha Mapping Project (LAMP) have shown that lunar surface reflectance in ultraviolet is sensitive to changes both composition and maturity at wavelengths >170 nm. This can lead uncertainties interpretation of features appear maps created using LAMP data from this wavelength range. Here we utilize a correction based on optical parameter remove large-scale immaturity spectral slope band ratio maps. After...
Europa-UVS plans to characterize the Europan exosphere by performing solar occultation measurements at key points during Europa Clipper mission. Observing Sun from Jovian space requires a system with high dynamic range. The end of range MCP-XDL detector is limited dead time effects and rated ~ 300 kHz, corresponding <1.2 μs requirement. global count rate estimated exceed this upper limit factor two measurements, due dramatic increase in photon flux towards (> 150 nm) bandpass...
Abstract Aristarchus crater is a Copernican-age impact well known for its high-albedo ejecta blanket and nearby flow features rich in pyroclastic materials. The Lyman Alpha Mapping Project (LAMP) far-ultraviolet (FUV) spectrograph (57–197 nm) on board the Lunar Reconnaissance Orbiter (LRO). LAMP data identified as having high Off-band (155–184 to On-band (130–155 albedo (Off/On) ratio, providing new insight into mineral composition of area. Previous observations bright rays lunar swirls show...
