Magnetometer and Electron Reflectometer (MAG/ER)
Objectives:
- Establish the Nature of the Magnetic Field of Mars
- Develop Models for Its Representation, Which Take into Account
the Internal Sources of Magnetism and the Effects of the
Interaction with the Solar Wind
- Map the Martian Crustal Remnant Field Using Fluxgate Sensors
and Extend These In Situ Measurements with the Remote Capability
of the Electron Reflectometer Sensor
- Characterize the Solar Wind/Mars Plasma Interaction
- Remotely Sense the Martian Ionosphere
Instrumentation:
Two Triaxial Fluxgate Magnetometers and an Electron Reflectometer
will be used. Two to sixteen vector samples per second of the in-situ
magnetic field will be acquired, and measurements of electron flux as
a function of pitch angle will resolve local surface fields.
