The GOES-R Magnetometer Engineering Development Unit made an important
development in the construction of the spacecraft recently after
completing a successful boom deployment test at an ATK facility in
The Geostationary Operational Environmental Satellite - R Series
advanced spacecraft and instrument technology will result in more timely
and accurate weather forecasts. It will improve support for the
detection and observations of meteorological phenomena and directly
affect public safety, protection of property, and ultimately, economic
health and development.
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 magnetometer will provide measurements of
the space environment magnetic field, which controls charged particle
dynamics in the outer region of the magnetosphere. These particles pose a
threat to spacecraft and human spaceflight.
"First deployment is always exciting, and all the dynamic effects
involved in the stowing and deploying need to be understood and
characterized," said Monica Todirita, instrument manager for the
magnetometer on the GOES-R Project at NOAA's National Environmental
Satellite, Data, and Information Service, Silver Spring, Md. "With first
deployment we proved that the design principle of the magnetometer boom
for our application is functional and reliable."
GOES-R will be more advanced than NOAA's current GOES fleet. The
satellites are expected to more than double the clarity of today's GOES
imagery and provide more atmospheric observations than current
capabilities with more frequent images.
"In geosynchronous orbit, Earth's magnetic field can go through huge
variations; sometimes nearly doubling in strength and at other times
reversing direction. GOES-R will monitor these variations and enable
forecasters at NOAA's Space Weather Prediction Center to better predict
the consequences of geomagnetic storms," said Howard Singer, chief
scientist, NOAA's Space Weather Prediction Center, Boulder, Colo.
NOAA manages the GOES-R Series Program through an integrated NOAA-NASA
program office, staffed with personnel from NOAA and NASA, and
co-located at NASA's Goddard Space Flight Center in Greenbelt, Md.
NOAA's mission is to understand and predict changes in Earth's
environment, from the depths of the ocean to the surface of the sun, and
to conserve and manage our coastal and marine resources.
