Merry Christmas to all people here, independently of their opinion.

Let us hope that the Ariane 5 team will tell us about their success wenn the Webb guy ‘lands’ at its Lagrange garage.

AFAIK it could take a year of maneuvering before the first images come in.

Maneuvering to get to L2. WMAP was/is there, Planck, Gaia too. Ok, some say 29 day transfer, but somewhere I heard a 1 year run-up. It is already 10 years late, 10 times over budget (not sure why).

Thank you Alan for the video link. Very interesting! I will will be subscribing to the “Curiosity Stream” plan (as offered at the end) soon as I can figure out the streaming procedures for my viewing resources here at home.

Does the “Curiosity Stream” plan include both Nebula and Real Engineering as a complete package deal. I do not subscribe to any cable service. Thanks again!

Webb will need to actively keep its orientation to stay at L2, but I don’t think it requires much propellant to stationkeep.

The Chinese lunar communications satellite is located at the Earth/Moon L2.

That’s right.
On the team’s to do list is, engineering a mission to refuel the Webb machine.

a year of maneuvering before the first images come in

Took longer than I expected (10s of minutes rather than 10s of seconds …), but a “quick” Internet search came up with the following.

Deployment schedule (link to Wikipedia) :comment image

From the “Webb Telescope” website ( https://webbtelescope.org/contents/media/images/4180-Image ) :

3RD MONTH: … By the end of the third month we will be able to take the first science-quality images. Also by this time, Webb will complete its initial orbit around L2.

4TH – 6TH MONTHS: At about 85 days after launch we will have completed the optimization of the telescope image in the NIRCam. Over the next month and a half we will optimize the image for the other instruments. We will test and calibrate all of the instrument capabilities by observing representative science targets.

AFTER 6 MONTHS: Webb will begin its science mission and start to conduct routine science operations.

So it looks like we should start to get “first light” images at the end of March / beginning of April, with “representative science target” images over the following 3 months before “full operations” start in June / July.

Looking at the actual measured WMAP L2 orbits above, I wonder if WEBB is so sensitive it will have to compensate for such an erratic ¨platform¨?

Besides, we already have Dark Matter, Dark Energy, and WEBB will not be able to look beyond the Dark Ages (no kidding!).

WEBB will see through golden mirrors darkly – to paraphrase Plato.

The after launch briefing said that it will be six months before the Webb telescope is fully deployed at it’s destination.

Never mind that the solar power array deployed early just after final separation.

Just watched it rocket off. So, what will replace rocket fuel when we arrive at clean and green energy nirvana? batteries?

Remember the guy who proposed a steam powered rocket with batteries to continue heating the water to make more steam? I haven’t seen any more along those lines. Maybe a real engineer or scientist did an energy balance to show why this can’t work.

The UAPs don’t use fossil fuels- only clean and green warp drives.

We need us one of those warp drives.

The space shuttle main engines were hydrogen/lox fuel, so it was a steam powered rocket. No batteries needed.

how did they make the H fuel? Without any fossil fuels?

Or a steam-powered rocket energized by a Solar Power Satellite beam. That’s pretty green.

I got one as a kid. Looked at the moon and freaked out. Of course I knew it was spherical but it doesn’t really look spherical to the naked eye. But in the scope, it was like looking at a basket ball held at arms length- and I could easily see craters. I found that thrilling- that was back around the time that JFK called for the moon mission.

About that same time I got my first microscope. Fun times. Now I’m 70 and I just found a pretty good working microscope in a thrift shop a few weeks ago. More fun. Yay!

The problem with a telescope is the weather where I live. It spends a lot of time in the closet because the clear night with no moon is rare indeed (if you want to search for galaxies instead of just looking at the moon and the bright planets). And when you get such a night, it is too cold to go out.

I heard similar problems affect people who yearn for a home solar panel.

North of the Alps, as weathermen say, Blue above, Grey under. The joke is Bavaria’s flag is a blue checker. Anyway that is not the worst – all street lamps were switched to LED. You have to go to the forest to view in Jan/Feb – which would freeze a brass monkey.
The yearning for the Atacama desert!!!

Apparently everything is OK so far. Should have had more cameras on the rocket stages like SpaceX does, tho they did have one on the uppermost stage to show the telescope release.

On my TV’s Roku box, I get the NASA channel- with old stuff and live stuff- watched the blast off on it- then it showed an animation of the rocket and how it dropped off stages. Almost like the real thing.

Even as libs annihilate, you still talk about crap.

German industrial production is down 10% since 2018. At this rate it will starve in 2030. Obviously much sooner.

US diesel production is down 10% since June. Total annihilation by 2023.

Chinese monthly electricity grew 30twh this year on 70twh of wind, hence their real electricity is falling and there are blackouts.

All your stats show your impending death and you only demand to die faster.

[Merry Christmas Mark. May the next year be good to you–Charles]
