Glenns' 1998, STS-95 return trip into space?

One of the purposes of the mission was to fly the Spartan-201
solar observatory (must get around to looking at that data again
sometime..). The purpose of having glenn on board was more obscure,
though I do recall comments to the effect that it was intended to
test the endurance of the rest of the crew.
