    Quite so.  Looking at the dozens of images of the GRACE pair,
    I don't see any way to get a glint off the spacecraft unless
    it is improperly oriented.  Check the image gallery:
    The trapezoidal ends were the only hope, and unfortunately their
    normals are perpendicular to nadir, which means glints could
    only occur during daytime.
