GRollins Posted December 26, 2021 Share Posted December 26, 2021 A large segment of our society has turned anti-science--if fact, they are actively hostile. That's going to come back to haunt us over time. For my part, I am quite excited to see what the Webb telescope turns up. It's going to be tough waiting for the telescope to come online.

stoken6 Posted December 26, 2021 Author Share Posted December 26, 2021 The thing is going to offer such insight and knowledge - if it works. There are many, many ways in which this mission could go wrong... I wish everyone involved the best of luck. Cheers, Mike. Quote Link to comment Share on other sites More sharing options...
Stokely Posted December 26, 2021 Share Posted December 26, 2021 Yeah, this one has some anxiety about it, from what I heard they aren't going to be able to get to it (currently at least) to fix anything. It's orders of magnitude more powerful than Hubble apparently. Quote Link to comment Share on other sites More sharing options...
RABid Posted December 26, 2021 Share Posted December 26, 2021 Been following this for a long time and was beginning to wonder if it would ever launch. It is still scary to think of all the things that can go wrong. Hard to believe they invested that much in something that cannot be repaired. But, I am looking forward to edge of the universe beginning of time information. Quote This post edited for speling.

Zydecat Posted December 26, 2021 Share Posted December 26, 2021 The Webb should provide an utterly amazing look back in time. Are we really a lonely planet? Quote Link to comment Share on other sites More sharing options...
Docbop Posted December 26, 2021 Share Posted December 26, 2021 Didn't know about this until the launch and read some articles this is an amazing project. Fingers crossed for next 30 days for everything to deploy correctly so we can learn more about the past thru scientific research. Quote Link to comment Share on other sites More sharing options...

But, I am looking forward to edge of the universe beginning of time information. Hopefully there's some redundancy as well as factors of safety that if X goes wrong, well that's not optimal but the slack can be picked up by Y. Or, we can't see the beginning of the universe but we can see from a million years after that. I haven't seen mention of this in the news articles I've read, but I don't expect anything but the most engineering-oriented of articles to cover that kind of thing. I have hope though. Look at the Mars rovers. They designed those things to last 60 or 90 days IIRC, and they crawled around Mars for years. Quote "I'm so crazy, I don't know this is impossible!

Bill H. Posted December 26, 2021 Share Posted December 26, 2021 Been following this project for years. Fully deployed the Webb will be four times further from Earth than the moon. The low Earth orbit Hubble has required five manned service missions to stay operational. For the Webb I'm hoping for the best, but prepared for the worst.

David Emm Posted December 26, 2021 Share Posted December 26, 2021 I've been following the project as well, so I'm chewing my nails in the hope that it will hit the mark, hugely outstripping the Hubble. Give this a read and be gobsmacked by things like the super-delicate beryllium panel polishing process, done under deep-space type temperatures to assure a good operational fit once its in service. Webb construction The U.S. share of the cost is a mere $10.8 billion. I wonder how many CS-80s that would buy? Or straitjackets?

Moonglow Posted December 27, 2021 Share Posted December 27, 2021 I saw a segment on television reporting that some of the maneuvers this thing needs to execute are incredibly precise, like within 1/1,000 of an inch. I can"t comprehend a number that small. A $10.8 billion-dollar mission riding on 1/1,000 of an inch? I hope I"ve got that wrong.

Rod S Posted December 27, 2021 Share Posted December 27, 2021 This is exciting! But yes, shocking the level of precision needed. I'm going look up those numbers. I actively followed the Hubble launch and 'fix'. One of my professors @ university (Duncan Moore) chaired the independent review panel in 1990 which came up with the correction for the spherical aberration in the main mirror. A few years later, I worked at a company that now owned the former Perkin Elmer building where they polished the mirror wrong (now a SVG Lithography Systems facility). Some of the guys from that era were still around and after a few beers you got them to share interesting stories.

3rdAct Posted December 28, 2021 Share Posted December 28, 2021 In an interview (on 60 Minutes, iirc), one of the engineers said that the team incorporated some potential solutions if something should fail to open. They can perform maneuvers that shakes the telescope or spins it clockwise or counterclockwise. Basically, the only ways to slap it on the side in deep space.

Tom Williams Posted January 10, 2022 Share Posted January 10, 2022 They may have to put up with a lull in the enthusiasm. The JWST will not be fully operational until June 2022. I don't think we can keep yelling "Rah! Rah!" that long without seeing some payback. But I bet they're gonna kick some esthetic butt this summer.

3rdAct Posted January 23, 2022 Share Posted January 23, 2022 Update on Webb telescope -- it's almost in position and everything going according to plan so far Webb update Quote Ground teams plan to fire Webb’s thrusters at 2 p.m. Monday, Jan. 24 to insert the space telescope into orbit around the Sun at the second Lagrange point, or L2, its intended destination, nearly 1 million miles from Earth. This mid-course correction burn has long been planned for approximately 29 days after launch. This week, the mission operations team selected the target date and time for the burn. Engineers also finished remotely moving Webb’s mirror segments out of their launch positions to begin the months-long process of aligning the telescope’s optics.

Now comes the fun part. Thirty days after its launch, the tennis court-size telescope made its way into a parking spot that's about a million miles away from Earth. From there, it will begin its ambitious mission to better understand the early days of our universe, peer at distant exoplanets and their atmospheres and help answer large-scale questions such as how quickly the universe is expanding. "Webb, welcome home!" NASA Administrator Bill Nelson said in a statement Monday after the massive telescope's final course correction.
