Magnetometer (MAG)
image:  Magnetometer
The GOES-R Magnetometer will provide measurements of the space environment magnetic field that controls charged particle dynamics in the outer region of the magnetosphere. These particles can be dangerous to spacecraft and human spaceflight. The geomagnetic field measurements are important for providing alerts and warnings to many customers, including satellite operators and power utilities. GOES Magnetometer data are also important in research, being among the most widely used spacecraft data by the national and international research community. The GOES-R Magnetometer products will be an integral part of the National Oceanic and Atmospheric Administration (NOAA) space weather operations, providing information on the general level of geomagnetic activity and permitting detection of sudden magnetic storms. In addition, measurements will be used to validate large-scale space environment models that are used in operations. The MAG requirements are similar to the tri-axial fluxgates that have previously flown. GOES-R requires measurements of three components of the geomagnetic field with a resolution of 0.016 nT and response frequency of 2.5 Hz.
Magnetometer Boom Deployment
This video demonstrates a successful boom deployment from the GOES-R Magnetometer Engineering Development Unit. The Magnetometer boom will deploy after the GOES-R spacecraft launches, separates from its launch vehicle, and undergoes a series of orbit raising maneuvers.
 
The magnetosphere is the comet-shaped region around the Earth that is affected by the Earth's magnetic field. It extends some 37,282 miles (60,000 km) from the Earth on the side facing the sun, but on the opposite side, it extends much farther. The boundary of the magnetosphere is called the "magnetopause.”
