    Default Will this thing match (or exceed) Hubble?

    Not really, if you look at the books. Most of the "Moon/Mars" wedge has
    come from eliminating JIMO (a nuclear powered Jupiter mission) and
    ISS/Shuttle.

    My oversight, George: I've always thought of it as SIRTF. There have
    been four "great observatories", as you note.

    Also that webb scope will NOT be looking in the visable light, it's designed
    for the Inferred area. Once Hubble goes down, only Land Based scopes will
    view the visable light.

    Yes. This is one of the real 'pities' of the sequences that have occured
    with instruments in the past, and will keep happening in the future. The
    original plan, was to have instruments covering a whole range of
    frequencies all operating at the same time. Over the years, some have
    'happened', while others have been delayed, or look as if they will never
    happen. The way things are currently running, it would not suprise me, if
    the Hubble is 'lost', before the Webb scope actually gets going. How bug
    free it will be, is then going to be interesting...

    Though it was a 'silly' failure, looking at it in retrospect, to me, the
    amazing thing is that Nasa had no QA on the product themselves....

    Best Wishes

    Well, actually, according to NASA, JWST will have visible light
    capability .. and more:

    I don't think a system that covers just half the visible band, can be
    considered to have 'visible light capability'. _Partial_ visible light
    capability possibly. However think of the spectral lines this leaves out.
    OIII, for example, is outside this 'coverage', let alone many of the lines
    towards the violet...

    It is a fine instrument, but it was meant to be launched to work alongside
    a visible light system, and systems covering the UV etc....

    Best Wishes

    True. As I understand it, they defined the mission objectives
    (identified at the JWST web site) and picked the spectrum accordingly.

    Don't forget redshift. JWST is designed to look so far away that
    visible light will appear as infrared.

    I should say "would appear." It's not going to get funded in its
    present form.

    A "Lissajous orbit"?

    Well, that thing better have darn good tracking! <g>
