MAXIE-1 (Magnetospheric Atmospheric X-ray Imaging Experiment)

The satellite flight of the MAXIE-1 (Magnetospheric Atmospheric X-Ray Imaging Experiment) instrument is being implemented under ONR (the Office of Naval Research) sponsorship. The MAXIE-1 instrument is being developed as a joint activity of Lockheed, the Aerospace Corporation, and the University of Bergen; much of the Lockheed development has been done under the Independent Research Program. Under ONR sponsorship that institution is responsible for managing the program, for providing spacecraft interface requirements, for providing interface electronics for conditioning sensor signals, for developing test software and for conducting environmental tests needed for flight. This report describes some of the interface activities undertaken in the last three months including the Interface Critical Design Review. Interactions have continued with co-investigators at the Aerospace Corp. and at the University of Bergen. A common board has been designed to condition spacecraft signals so as to make them compatible with the MAXIE instrument and vice-versa for the MAXIE signals. A breadboard of this common board has been fabricated and tested.
