[PPS08-10] Spectral Comparison between Space-Weathered Anorthosite and D-type Spectra on the Martian Satellites based on Hyperspectral Remote Sensing
Keywords:Martian satellites, remote-sensing, hyper spectral
Recently, we have found that the spectral features of lunar space-weathered anorthosite are consistent with D-type spectra, including those of Phobos and Deimos. From this point of view, we proposed a possibility that the surfaces of Phobos and Deimos are dominated by space-weathered anorthosite (SWA hypothesis). In this presentation, we will demonstrate how various observational results for Phobos and Deimos are consistent with spectra expected from SWA hypothesis. In addition, we will discuss how the red and blue units on Phobos can be explained by SWA hypothesis. Moreover, we will also discuss the relation between SWA hypothesis and the giant impact scenario.
