Geological features and evolution history of Sinus Iridum, the Moon
Xiao, Long; Qiao, Le; Zhao, Jiannan +2 more
The Sinus Iridum region is one of the important candidate landing areas for the future Chinese lunar robotic and human missions. Considering its flat topography, abundant geomorphic features and complex evolutionary history, this region shows great significance to both lunar science and landing exploration, including powered descent, surface traff…
Mapping lunar mare basalt units in mare Imbrium as observed with the Moon Mineralogy Mapper (M³)
Hiesinger, H.; Besse, S.; Thiessen, F. +1 more
We examine compositional variations of volcanic units in the Imbrium basin using spectral observations from the Moon Mineralogy Mapper (M³) instrument on board the Chandrayaan-1 spacecraft. The spectral range of M³ reflectance measurements from 400 to 3000 nm is well-suited to study distinctive absorption bands near 1000 and 2000 nm resulting from…
C1XS results-First measurement of enhanced sodium on the lunar surface
Grande, M.; Narendranath, S.; Sreekumar, P. +1 more
We describe the first unambiguous evidence of enhanced sodium on the lunar surface revealed by the Chandrayaan-1 X-ray Spectrometer (C1XS). The C1XS onboard the Chandrayaan-1 spacecraft was designed to map the surface elemental chemistry of the Moon using the X-ray fluorescence (XRF) technique. During the nine months of remote sensing observations…
