Deployment sequence; you can click on each step (at the top of the screen) and see when things are supposed to happen. It’ll take 29 days to get to the L2 point.

Another NASA site showing progress to L2 and the deployment.

Is the mirror image of a photo meant to avoid copyright law for stealing someone else’s photo?

I see it so many times that I can’t imagine any other explanation.

FWIW NASA photos are copyright free, as our tax dollars paid for them, so you can use and abuse them any way you want to.

I am told that there was such a sign on the Webb and that it WAS removed before launch. ;-)

Santa flies in a low earth orbit at night. No collision possible. ;-)

But he probably flies faster than the speed of light, which is impressive.

I thought Santa flew Near-Earth Orbit Extremely Low (NOEL).

Id have to check NASA records for the first NOEL....

A very good video on the design and engineering:

Heat shield now fully deployed and tensioned. JWT now the coolest thing in space!

India Four Two 4th Jan 2022 18:36

BBC report on the heat shield:


There were many who doubted the wisdom of a design that included so many motors, gears, pulleys and cables.

But years of testing on full-scale and sub-scale models paid dividends as controllers first separated the shield's different layers and then tensioned them.

Really good news.

They did the burn for the insertion orbit around the L2 point

“Scientists and engineers operating NASA’s James Webb Space Telescope will answer questions about the mission’s latest milestones in a NASA Science Live broadcast at 3 p.m. EST Monday, Jan. 24, followed by a media teleconference at 4 p.m.“

Webb team brings 18 dots of starlight into hexagonal formation

NASA have released a new image that they say demonstrates that JWST's optics are 'working successfully'. The image shows an extremely promising level of detail in the surrounding area of the star they arbitrarily chose to focus on. Which incidentally is 100 times feinter than you'd be able to see with the naked eye from Earth. :O
