abstract |
The UK-built Chandrayaan-1 X-ray Spectrometer(C1XS)will fly as an ESA instrument on
India’s Chandrayaan-1 mission to the Moon, launched in October2008. C1XS builds on
experience gained with the earlier D-CIXS instrument on SMART-1, but will be a scientifically
much more capable instrument. Here we describe the scientific objectives of this instrument,
which include mapping the abundances of
the major rock-forming elements (principally Mg, Al, Si, Ti, Ca and Fe) in the lunar
crust. These data will aid in determining whether regional compositional differences
(e.g., the Mg/Fe ratio) are consistent with models of lunar crustal evolution. C1XS
data will also permit geochemical studies of smaller scale features, such as the ejecta
blankets and central peaks of large impact craters, and individual lava flows and
pyroclastic deposits. These objectives all bear on important, and currently unresolved,
questions in lunar science, including the structure and evolution of any primordial
magma ocean, as revealed by vertical and lateral geochemical variations in the crust,
and the composition of the lunar mantle, which will further constrain theories of
the Moon’s origin, thermal history and internal structure. |
