James Webb Space Telescope reaches launch pad for Christmas liftoff

The James Webb Space Telescope is due to launch on Saturday (Dec. 25) during a 32-minute window that opens at 7:20 a.m. EST (1220 GMT). The massive observatory will blast off from Kourou, French Guiana, atop an Ariane 5 rocket operated by European launch provider Arianespace. You can watch launch coverage live at Space.com beginning at 6 a.m. EST (1100 GMT) courtesy of NASA or you can watch directly at the agency's website.

    It's in orbit now.

    How long til it reaches Mars and initiates planetary oxygenation?

    Damn I missed the launch. I just assumed it would be pushed back again!

    I was watching Scott Manley's video yesterday on Webb and I think he said it will take about 2 weeks to get into the final orbit out past the moon-earth L2 point. They undershot on the upper stage because there was a risk it would be an over-performing engine and send the telescope out past it's orbit, with too much energy for the telescope to use it's fuel to return.

      Yeah, I'd put aside some time in 2029 too.

    Making it past the swirling swarm of space junk around our poor old planet is a big step. The things that Hubble brought us must be appreciated and not forgotten. Webb is the next stage, the next generation - decades on. I feel privileged to live to see the wonders this new instrument will show us about the universe.

      Not really. Most of what is up there is easily avoided if you are just passing through. The trouble happens when you stay in near Earth orbit, because repeated near-misses means something will eventually hit.

        Most of what's up there, by mass, is avoidable. However, when a speck weighing 1/10 of a gram carries as much energy as a high power rifle round, it's the myraid more in number small things that you actually need to be afraid of, as they can kill something a million times their size. We're a sphere - we're potentially an infinitude of collider beams everywhere, and those particle beams are invisible to us.

      Well, if you read Dante, you'll know that the innermost circle of Hell is already a permanently frozen waste.

        So... telling Musk to go to hell is merely encouragement for his existing endeavour?
