  Space-based platforms like the Hubble, Cassini, or Chandra.

    Orbital platforms that are still operated by Earth-based astronomers, no? I don't intend to argue semantics, just think it's a poor (and somewhat funny) choice of words.

      Perhaps, but that's how the platform deployment is described.
