Under subcontract to Lockheed Martin Missiles and Space (LMMS), TRW Space and Electronics Group is developing the first operational flexible blanket solar array to use thin gallium arsenide on germanium (GaAs/Ge) solar cells and to produce power at high voltage. This single wing array will be integrated to the EOS AM-1 spacecraft which is the first in a series of Goddard Space Flight Center remote sensing spacecraft. Spacecraft system level design issues dealing with package volume, attitude control, weight and array size dictated that a low aspect ratio (2:1), flexible blanket wing with GaAs/Ge cells be used. The array program is in its last phase of protoflight verification testing with delivery of the wing to LMMS in mid-1997 for launch into orbit in mid-1998. This paper continues the status reporting of the solar array development that was first presented at the 31st IECEC in Washington, DC. In the first paper (Herriage, et al, 1996) the focus was on the design requirements and evolving design details. This paper provides a brief review of the wing configuration and design as a point of reference for the ensuing principal discussion of the protoflight verification test program and key results.
