    Space Post - James Webb space telescope

    This is aimed to be launched in 5yrs time... Should be interesting. Compared to Hubble - http://jwst.nasa.gov/comparison.html





    Webb will have a 6.5 meter diameter primary mirror, which would give it a significant larger collecting area than the mirrors available on the current generation of space telescopes. Hubble's mirror is a much smaller 2.4 meters in diameter and its corresponding collecting area is 4.5 m2, giving Webb around 7 times more collecting area! Webb will have significantly larger field of view than the NICMOS camera on Hubble (covering more than ~15 times the area) and significantly better spatial resolution than is available with the infrared Spitzer Space Telescope.
    Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.

    Looks like something you'd cobble together in Kerbal Space Program!

    On a serious note:

    Hubble is in a very close orbit around the earth, while Webb will be 1.5 million kilometers
    That's one hell of a call out job for repairs - they can't just pop up there in shuttle this time and I'm not sure Green Flag go that far...

    Be interesting to see what it can find though!

    True, but knowing MCDonalds, they'll have a restaurant there!
