ACE/MAG Project[Image]

         The Bartol Research Institute (BRI) in         [ACE Logo]
         collaboration with the Laboratory for
         Extraterrestrial Physics (LEP) at the Goddard
         Space Flight Center (GSFC), has built and
         delivered  a magnetometer instrument which
         was flown on the Advanced Composition
         Explorer (ACE) from the Kennedy Space Center
         on board a Delta rocket on August 25, 1997 .

Magnetometer Instrument

The Magnetometer instrument consists of   [MAG Electronics and one sensor]
one electronics box mounted on the
spacecraft top deck and of two sensors mounted at the end of two boom.

ACE Spacecraft

The spacecraft was built at the Applied Physics       [ACE/MAG Spacecraft]
Laboratory of the John Hopkins University in Laurel,
MD. The photo at right shows how the magnetometer sensors are mounted at
the end of of two secondary booms hinged at the end of two of the four
solar panels.
