Nothing more than sensationalism They are planning to put a replacement telescope satellite beforehand... Hubble is dead, long live Hubble http://www.aviationnow.com/avnow/news/channel_awst_story.jsp?id=news/07073to p.xml The competition to build the James Webb Space Telescope ended last year with the selection of a contracting team headed by Northrop Grumman Space Technology. Eight years from now, an Ariane 5 is expected to boost the 5,400-kg. (11,880-lb.) observatory toward the second Lagrangian point (L2), 1.5 million km. (930,000 mi.) beyond Earth's orbit. There, the Sun and Earth will be on a relatively straight line with the satellite, which minimizes the effects of their light on its optics, and their gravitational pull will be pretty much in balance, giving it a relatively benign parking spot. L2 OFFERS THE closest practical orbit for the deep space cold soak that the telescope needs. To assure a temperature range of 30-35K, the telescope and its Integrated Science Instrument Module (ISIM) will be shielded from sunlight by a five-layer sunshield as big as two tennis courts. In this cold, its infrared detectors will be so sensitive that they can chase the red-shifted light of receding time as far back as the start of time itself, back some 14 billion years to the moment when astronomers think the Big Bang went bang. Astronomers call these first moments of creation the dark ages because no observatory has been powerful enough to penetrate them. What scientists know about the opening scenes of time is theory; they haven't seen the enactment. Cl... Perhaps they'll see God at U 0,0,0.

Actually, IIRC, the Webb telescope is not supposed to be launched until at least 2012, and we all know how likely launch dates are to be delayed. The main problem with keeping Hubble in service until after the Webb telescope is in place is that doing so would cost about $150 million each year. A further point to consider is that, while Hubble is able to take pictures of distant objects inside our solar system, Webb will not be able to look at anything except objects beyond our solar system, as it will be unable to track moving objects like planets. -- Ronn! :) ___ http://www.mccmedia.com/mailman/listinfo/brin-l

Steven V.W. Beckwith, director of the Space Telescope Science Institute at the Johns Hopkins University, which operates the instrument, told a National Aeronautics and Space Administration panel the money will ensure that Hubble continues to capture pictures that help scientists unravel mysteries about the origin and nature of the universe. It's up there, it works well and it's pretty easy to service it, Beckwith told a group of astronomers and planetary scientists appointed to look into Hubble's future. But there was far from unanimous agreement on extending Hubble's life. http://www.sunspot.net/news/local/howard/bal-ho.te.hubble01aug01.story unquote I would argue for something 100 times less expensive.

If so, then it's not the cost of operating the thing, but the cost of the scientific output it produces - which will be almost the same if you replace it by a newer model. I would argue for something 100 times less expensive. Perhaps you should put in a bid to NASA to run it, then . . . Who me? A dangerous alien? I might use it to spy the USA and sell the information to North Korea! Alberto Monteiro ___ http://www.mccmedia.com/mailman/listinfo/brin-l
