James Webb Telescope - December 24th

Exciting.

Ya I was just reading about this. Unfortunately all of its ability to "see" is in the IR range so we're going to get a lot of touched up photos.

Hubble for example is able to see mostly in visible light and a tiny bit of IR.

All the visible light from that long ago is red shifted into infrared. There is none in the visible wavelength.

They can reverse shift them to what they looked like when the light left.

I have a feeling this is going to be a cluster ****.

Hope not. Now pushed to Dec 25th. I think there are like 300 operations that need to happen in order for it to work perfectly. But they've been testing it for years and know of the issue with the Hubble mirror so hopefully it all works out.

Like all space hardware it is totally untested in it's actual operating conditions. There are about 300 critical points that can abort the entire mission.

There will be a lot of bad sleep in the next few months until it is in find condition and unfurled.

I used to aerospace and I thought the documentation and testing for that was extensive. This is going to be orders of magnitude more comprehensive.

Yea, they say there are many people who've worked their entire careers on this endeavor. It's not like just getting a satellite into orbit, it'll take many weeks to fully unfold and boot up. I heard that if each failure point only had a 99% success the entire thing would be around 70%.

I'm looking forward to the launch and following progress.

About 6 months for it to be fully operational.

This telescope might just be able to image that invasion fleet trailing after Oumuamua!

Whats the launch platform?

Whats the launch platform?

Ariane 5

That was the European contribution to the mission as the whole thing pretty much had to be built in the US. For that, they get 15% of the time on the Webb.

Thanks.

Looks like its got a 96% chance of making it.....

Good piece on the Washington Post website this morning - https://www.washingtonpost.com/scie...ce-telescope-launch/?itid=hp-more-top-stories
