    do the still images just get updated occasionally ?
    as the timers on the cams are not running ... or do I need some other viewer software ?

    It seams to be about one shot per minute if I'm not mistaken.

    Let's hope this one isn't plagued by poor management.

    Couple of screen shots of the progress.

    Are those panels made out of tellurium? Looks big... Might detect aliens. :)

    Sweet! Can't wait to see this telescope launch.

    Take a look at the link in post #5, I believe the WFIRST and JWST are meant to be used in tandem on certain projects involving imaging the very early universe. :thumbup: I just hope I live long enough to see the results.
    Upon closer reading I see that the primary purpose of WFIRST will be as a Kepler replacement/upgrade for exoplanet hunting, however it will be teamed up with JWST also for imaging the very earliest universe possible.

    :thumbup::thumbup: That's two thumbs up on the post. I read that the mechanical deployment will be going through very intensive testing as that is the one aspect they cannot simulate in their cold vacuum chambers due to size, they have to get it right first time out of the box.

    The primary goal of WFIRST is cosmology. It will use three of the major tests, baryon acoustic oscillations, weak lensing and supernovae. It will complete at 2-3000 square degree survey with both near infrared slitless spectroscopy and deep near infrared imaging. It was originally a dark energy mission but it's slightly oddly placed now with the major change in design caused by the use of the NRO telescope. It also has major overlap with Euclid which will fly earlier.

    Exoplanets were a secondary consideration, it's certainly not a Kepler replacement. The two exoplanet major projects will be a very high contrast coronograph to image large planets and a microlensing survey to detect free floating planets and get better statistics of planets far from their stars unlike Kepler which couldn't do that.

    I didn't see a sarcasm icon in that post of yours.

    It's hard to fathom that nobody has challenged you on this yet, V50. The JWST has been plagued by poor management from day one. The initial 1997 estimate was half a billion dollars for a 2007 launch. The current estimate is 8.8 billion dollars for a 2018 launch. That's over an order of magnitude increase in cost and over a decade slip in launch time.
