Mercury's Surface Composition and Character as Measured by Ground-based Observations
2007 (English)In: Space Science Series of ISSI, 2007Chapter in book (Refereed)
Mariner 10 made no measurements that directly measured the surface composition of Mercury. However, the 45% of the surface that was imaged is heavily cratered and in that sense resembles the Moon. Also the crater morphology and tectonic expression of fault scarps and ejecta rays give the strong impression that the surface is covered with silicates. This impression has been supported by ground-based observations that have identified key indicators in spectral measurements that appear similar to spectral measurments of silicates in the laboratory and on the Moon. Some spectra have been interpreted in terms Mercury's surface composition. These are summarized below and discussed in the context of the challenges and opportunities of future ground-based observations and orbital measurements by the MESSENGER and Bepi Colombo spacecrafts.
