One Moon, Many Measurements 3: Spectral reflectance
Yokota, Y.; Mall, U.; Besse, S. +9 more
Remote-sensing datasets obtained by each instrument aboard Selenological and Engineering Explorer (SELENE) and Chandrayaan-1 have not been compared directly, and the characteristics of each instrument’s data, which may reflect the observation conditions of each instrument and/or residual error in instrument calibration, are unknown. This paper des…
Gullies and landslides on the Moon: Evidence for dry-granular flows
Mustard, John; Ostrach, Lillian R.; Kiran Kumar, A. S. +7 more
High-resolution images from Chandrayaan-1 Terrain Mapping Camera and Lunar Reconnaissance Orbiter Camera reveal landslides and gully formation on the interior wall of a 7 km-diameter simple crater emplaced in Schrödinger basin on the farside of the Moon. These features occur on the steep upper crater wall, where the slope is ~35°. The gullies show…
Remote energetic neutral atom imaging of electric potential over a lunar magnetic anomaly
Barabash, S.; Futaana, Y.; Wurz, P. +5 more
<title type="main">Abstract<p label="1">The formation of electric potential over lunar magnetized regions is essential for understanding fundamental lunar science, for understanding the lunar environment, and for planning human exploration on the Moon. A large positive electric potential was predicted and detected from single point mea…
Energetic neutral atom imaging of the lunar surface
Barabash, S.; Holmström, M.; Futaana, Y. +7 more
Since the Moon is not shielded by a global magnetic field or by an atmosphere, solar wind plasma impinges onto the lunar surface almost unhindered. Until recently, it was assumed that almost all of the impinging solar wind ions are absorbed by the surface. However, recent Interstellar Boundary Explorer, Chandrayaan-1, and Kaguya observations showe…
One Moon, many measurements 2: Photometric corrections
Yokota, Y.; Mall, U.; Besse, S. +10 more
Observations of the lunar surface within the past 10 years have been made with various lunar remote sensing instruments, the Moon Mineralogy Mapper (M3) onboard the Chandrayaan-1 mission, the Spectral Profiler (SP), the Multiband Imager (MI), the Terrain Camera (TC) onboard the SELENE mission, and the ground based USGS Robotic Lunar Obs…
New results and questions of lunar exploration from SELENE, Chang'E-1, Chandrayaan-1 and LRO/LCROSS
Jin, Shuanggen; Arivazhagan, Sundaram; Araki, Hiroshi
The moon has longstanding questions such as lunar environments, origin, formation and evolution, magnetization of crustal rocks, internal structure and possible life. The recent lunar missions, e.g., SELenological and ENgineering Explorer "KAGUYA" (SELENE), Chang'E-1, Chandrayaan-1, and Lunar Reconnaissance Orbiter/Lunar CRater Observation and Sen…
Mineralogy of Mare Serenitatis on the near side of the Moon based on Chandrayaan-1 Moon Mineralogy Mapper (M3) observations
Bhattacharya, Satadru; Chauhan, Prakash; Kiran Kumar, A. S. +2 more
Spectral analysis of Mare Serenitatis has been carried out using Chandrayaan-1 Moon Mineralogy Mapper (M3) data in order to map the compositional diversity of the basaltic units that exist in the basin. Mare Serenitatis is characterized by multiple basaltic flows of different ages indicating a prolonged volcanism subsequent to the basin…
Near-infrared optical constants of naturally occurring olivine and synthetic pyroxene as a function of mineral composition
Trang, David; Gillis-Davis, Jeffrey J.; Klima, Rachel L. +3 more
Radiative transfer theory will assist in determining olivine and pyroxene proportions and compositions from the surface of a planetary body composed of intimately mixed minerals. In order to use radiative transfer techniques, the model requires the optical constants of olivine and pyroxene. Optical constants are parameters that describe the degree…
One Moon, many measurements 1: Radiance values
Yokota, Y.; Mall, U.; Besse, S. +10 more
Several modern optical instruments orbited the Moon during 2008 and 2009 onboard the SELENE and Chandrayaan-1 spacecraft and provided a welcomed feast of spectroscopic data to be used for scientific analyses. The different spatial and spectral resolutions of these sensors along with diverse illumination geometry during data acquisition make each s…
Redistribution of lunar polar water to mid-latitudes and its role in forming an OH veneer
Delory, G. T.; Halekas, J. S.; Farrell, W. M. +4 more
We suggest that energization processes like ion sputtering and impact vaporization can eject/release polar water molecules residing within cold trapped regions with sufficient velocity to allow their redistribution to mid-latitudes. We consider the possibility that these polar-ejected molecules can contribution to the water/OH veneer observed as a…
