3/12/2015 – LASP at Mercury: The MASCS instrument on the MESSENGER spacecraft

Speaker: Tim Cassidy (LASP)
Date: Saturday, Mar 12, 2022
Time: 4:00 PM
Location: SPSC W120

Seminar Abstract:

The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft will end its mission at the end of April, crashing into the surface after four years in orbit and over a decade in space.  One of its instruments, the Mercury Atmospheric and Surface Composition Spectrometer (MASCS), was built here at LASP. In this talk I will give an overview of MASCS’ observations of Mercury’s surface reflectance and exosphere emissions. I will also review the science highlights from other instruments, such as Mercury’s surprising surface composition and dynamic magnetosphere.
