| NAME |
MERCURY ATMOSPHERIC AND SURFACE COMPOSITION SPECTROMETER
|
| TYPE |
SPECTROMETER
|
| DESCRIPTION |
The Mercury Atmospheric and Surface Composition Spectrometer (MASCS) is comprised of a small Cassegrain telescope with a 257-mm effective focal length and a 50-mm aperture that simultaneously feeds both an UltraViolet and Visible Spectrometer (UVVS) and a Visible and Infrared Spectrograph (VIRS). MASCS will investigate Mercury's exosphere by measuring altitude profiles of known species as well as searching for previously undetected species. MASCS will investigate the mineralogical composition of the surface of Mercury by obtaining maps of surface reflectance spectra on spatial scales of 5 km. Together, the VIRS and UVVS detectors will measure surface reflectance at middle ultraviolet to visible to near infrared wavelengths to search for ferrous bearing minerals, Fe- Ti bearing phases, and ferrous iron.
