The Lunar Polar Hydrogen Mapper (LunaH-Map) mission will map the distribution of hydrogen around lunar South Pole using a miniature neutron spectrometer. builds upon decade science, which has revealed both regional and more localized enrichments water ice near poles. Localized are primarily within permanently shadowed regions (PSRs) craters throughout Pole. spatial extent these is often below resolution previous instruments that have flown on missions. leakage spectrum from planetary...
Three n-type high-purity germanium (HPGe) detectors were irradiated with protons at solar and galactic cosmic ray energies, fluences corresponding to ≥3 years of exposure the interplanetary radiation environment. Following 1 GeV proton irradiations (8×108 cm−2), annealing 105°and 115 °C resulted in full energy resolution recovery after 240 140 h annealing, respectively. A second irradiation, consisting 7.25x109 cm−2 a solar-proton-like spectrum, within <316 105 °C. Prior spaceflight...
Abstract The Dynamic Albedo of Neutrons (DAN) instrument on the Mars Science Laboratory Curiosity rover primarily measures neutrons that have undergone interactions with rocks and materials in rover's local environment. As ascends Aeolis Mons, it may encounter more extreme topography (e.g., cliffs, gullies, canyons). We present three parts traverse which topography, expressed as average relief relative to rover, is moderately strongly correlated an increase passive thermal neutron count...
This work investigates a novel signature for measuring the Ni/Fe ratio on asteroid (16) Psyche that is robust against interference from large Solar Particle Events. NASA's mission launched October 13th, 2023, and headed to investigate this M-type asteroid. A primary science requirement gamma-ray spectrometer measure absolute surface abundance of Ni Fe. In particular, will help test hypothesis metal-rich body, possibly remnant core failed planetesimal. However, Events can activate iron in...
