Mercury cratering record viewed from MESSENGER's first flyby.
Morphologies and size-frequency distributions of impact craters on Mercury imaged during MESSENGER's first flyby elucidate the planet's geological history. Plains interior to the Caloris basin displaying color and albedo contrasts have comparable crater densities and therefore similar ages. Smooth plains exterior to Caloris exhibit a crater density approximately 40% less than on interior plains...
متن کاملSpectral emissivity measurements of Mercury’s surface indicate Mg- and Ca-rich mineralogy, K-spar, Na-rich plagioclase, rutile, with possible perovskite, and garnet
Mid-infrared 2-D spectroscopic measurements from 8.0 to 12.7mm of Mercury were taken using Boston University’s Mid-Infrared Spectrometer and Imager (MIRSI) mounted on the NASA Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii, 7–11 April 2006. Measurements reported here cover radar bright region C, a dark plains region west of Caloris Basin, and the interior of Caloris Basin. By use of sp...
متن کاملInvestigating the Formation and Structure of Mercury's Caloris Impact Basin
Introduction: With a diameter of ~1500 km [1,2], Caloris is the largest impact basin on Mercury and one of the largest within the Solar System. Caloris, formed ~3.9 Ga [3], is also the best-preserved large mercurian basin. The basin was first imaged in its entirety by the Mercury Dual Imaging System (MDIS) onboard the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spa...
متن کاملGeology of the Caloris basin, Mercury: a view from MESSENGER.
The Caloris basin, the youngest known large impact basin on Mercury, is revealed in MESSENGER images to be modified by volcanism and deformation in a manner distinct from that of lunar impact basins. The morphology and spatial distribution of basin materials themselves closely match lunar counterparts. Evidence for a volcanic origin of the basin's interior plains includes embayed craters on the...
