Hmm, the near Earth environment is rather messy with all that stray
atmosphere, plasma and fields. Wouldn't a solar sail behave a bit
oddly there due to confounding variables? For example, if it is
conductive it would act as a electric tether, and plasma streams might
give it extra push or resistance beside the obvious weak drag from the
atmosphere. Somehow I think they have taken this into account, but it
makes interpretation of the experiment much harder.
