There's really no point in a human being there as all of the photons gathered are directed to an electronic sensor. A human does not need to guide the scope any longer either. Really, if the scope is operated by the ESA, the remote location could be in the EU, or if NASA in the US, or for this one it could be in Japan.
You'd only need a small crew of techs that could be available to perform maintenance, but all of the operations could be much closer to home.
