This is a temporary thread dedicated to posting about the James Webb telescope, which will remain pinned until shortly after it's launch which now appears to be no earlier than December 22nd. All discussion concerning the telescope is to be had here and any new threads will be locked without notice. All posts must remain within the boundaries of the Cloudy Nights Terms of Service and any that violate same will be promptly removed without notice with the posters possibly facing the wrath of the moderators and administrative staff. Be ye forewarned!

So, the launch was scrubbed because of us? CN gone wild?

 

For me, I'd prefer to have one source for updates rather than seeking crumbs from throughout the internet-truthiness machine. Thanks Mods for setting this up.

I have a vested interest in JWST's successful deployment and operation. I worked on JWST metrology suites, including patents on the COCOA Null Lens and a couple of coarse and fine alignment sensors. The null lens preformed magnificently, as required. The long time from concepts to actualization are reflected in the patent application and issue dates! Here's hoping that everything goes right from this moment on! A lot is riding on this Ariane 5 rocket!  Tom

Thank you for your contribution! I have been following JWST for years, every scrap of news as Canada has contributed to JWST too. This is an exciting time, my excitement about JWST finally launching is causing me some skips of the heart when thinking about the risks of launch and deployment.

For sure. Imagine how the scientists and other workers are feeling. We had a presentation by Dr. Matthew Greenhouse who has worked on JWST for 27 years. All that work could potentially evaporate in a few seconds with a launch failure. I don't think that I could stand the stress and worry.

 

Special people do this kind of work.

Apparently, they are getting data packet loss on the hard comm line connecting the payload to ground launch facility.

They had same issues with the IXPE and DART payloads recently and decided to go ahead with launch.

This time they are determined to find definitely what is causing the packet loss before launch of Webb.

I am really exited about what the James Webb might find in the infrared.  Perhaps a phenomenon that completely overturns existing theories about the universe. Maybe some evidence to help better define the concept of the singularity and initiation of time……..or something else. This is great stuff.

I'm personally rooting for the "or something else".

My favorite discoveries are the ones ya never even saw coming!

I’m with you on that. My bet is that,eventually, we will realize that we are incapable of comprehending the mechanics beyond 13.8 billion years.

So, your telling me that they only found a problem because they tested for it? I thought we had a recent Chief Executive whose pandemic plan was to stop testing for the virus so we could stop finding it. Now I am confused.

Same here. I hope in 5 years we will be talking here about stuff we did not know it even existed.

But first let's hope in will deploy as planned!

If all goes as planned we should begin having those discussions a year from now. Still, dropped packets on a hard comm line... Really glad I'm not in the decision making loop.

EDIT:   Also, this article in the local (Los Angeles "south bay" beach-cities) newspaper is well worth a read ...

Realistic optimism is hoping that all of the anomalies will be minor addressable glitches. Here's hoping; ~Good Luck JWST!~   Tom

Yes. Just like with software development -- only in the movies does someone's code work perfectly the first time, when it was written ridiculously quickly under immense pressure.
