I fold paper towels a lot when I'm cleaning, but it doesn't seem to help me jump forward to being done cleaning. Sad.

You are thinking of a warp drive. Wormhole is more like a tunnel thru spacetime.

That’s a lot of engines. I hope it lights up with no problems

If you understand how a U-shaped piece of paper with two points connected by a tunnel would work...
I'm not sure there's much more to the understanding.
That's how it's possible.
The physics inside a wormhole wouldn't be like that of the paper certainly.
After all, it's not paper and a tunnel. It's connecting two singularities in a way that gets rid of their infinite natures in a physically accurate way.
But it means you can't pass information through them. Because the information can never move faster than light and the space between these two black holes would.
At least that's what I take from EPR=EP

I saw on one of the space blogs (that I'm too lazy to find) that they brought massive bags of super-strong concrete (refractory cement?) for the pad after the last damage, and those bags disappeared so it was assumed the new cement had been used, but they were later spotted elsewhere at the facility, so there was some conjecture that they may have used standard cement again and doing this knowing it is a sacrificial pad. So don't be too surprised, or too concerned if the pad is damaged - the fancy cement is on site.

Contract space-time in front of the crafts, expand space-time behind them. How? Not sure.

Heat isn't really the primary concern here. The big risk is vibration. The sound waves from 33 engines firing at once are enough compressive force to literally break apart steel.

nasaspaceflight (not part of nasa) has permanent streams of starbase operations, and cape operations. I am sure lap padre will also livestream it.
Keep in mind that falcon heavy uses 27 engines at the same time (+1 on the upper stage).

I’m a space brainlet, but there’s something about “welding” and “rockets“ that makes me kinda nervous.

Ill take that trade. Lets cross our fingers for another superbowl visit in a few years or so before the first of the Mars missions then.

Considering that it's 100 million km away I think we're fine

From the FAA, they got a mitigated Findings Of No Significant Impact, meaning they were given a checklist of like 70 items they had to complete in order to proceed. That was in the middle of last year, and they've been working on that behind the scenes. Most of it was pretty basic stuff.

Reply to UCLA scientists, Dr. Eric Kang Ting and Dr. Chia Soo, in collaboration with NASA and the Center for the Advancement of Science in Space are performing experiments in space to test an experimental drug that could one day result in a treatment for osteoporosis. More in the comments. by tarkool
This experiment marks the first time that UCLA scientists will send rodents to the International Space Station. According to the article, "After living in microgravity and receiving NELL-1 injections for about four weeks, half of the rodents will return from space and land in the Pacific Ocean off the coast of Baja, California."
Dr. Eric Ting Kang first discovered the NELL-1 protein in 1996 and, "NELL-1 has a powerful effect on tissue-specific stem cells that create bone-building cells called osteoblasts. When exposed to NELL-1, the stem cells create osteoblasts that are much more effective at building bone. Furthermore, NELL-1 reduces the function of osteoclasts, which are the cells that break down bone."

I guess I tuned out waiting on EPA regulation but that was all resolved?

Well, no, there really isn't. You say Webb produces data 'without intervention by a human', and 'a huge amount of findings [are] produced by an algorithm'. That's a really weird way of putting it, because the vast majority of Webb time is obtained by individual projects designed to look at specific things, with dedicated analysis plans. Of course there's a nonneglible amount of bycatch, so to speak - but that's not what I read in your comment.

Very fair and true. There are some of the world's most brilliant people doing that work, history making stuff. I wouldn't want to diminish their effort. At the enterprise level, in terms of how tf do you build a space company when at the time there weren't too many examples and virtually no examples of non-major-contractor launch providers, especially with an indigenous system. The fact that she took them through that totally unknown terrain, giving the rest of the brilliant minds the runway they needed to create something wholly new, that deserves a lot more public attention than perhaps she gets.
But again, I agree with you. It takes a village of geniuses.

While that may sort of true don’t under estimate others heart either. And I’m not talking about Elon either.

Pad can take it it’s got diverters I’m more worried about things that are meant for air flow for cooling. Assuming test is time limited.

Their last Super Bowl trip was just before the first Falcon Heavy launch. Destined to always be overshadowed by SpaceX!

Pray for no errors or hardware failures. Even though that’s a form of excelling.

Yikes, there's too much to unpack here but I think what you're referencing is the images that are created from the archive. Are you familiar with the 3 stages of the pipeline?
Remember too, there are 10 detectors in the JWST, and the limit in the SSR is only 65GB, so much of the processing is done on board to reduce data excess. Tons more info can be found here: https://jwst-docs.stsci.edu/jwst-general-support/jwst-data-volume-and-data-excess
More info on the data pipeline can be found here: https://jwst-docs.stsci.edu/jwst-science-calibration-pipeline-overview/stages-of-jwst-data-processing#:~:text=The%20processing%20of%20JWST%20data%20goes%20through%203,%28slope%29%20images.%20Stage%202%20calibrates%20the%20slope%20images.
Also keep in mind JWST does thousands of exposures using many of the instruments. That data is accumulated in the SSR and is streamed every 12 hours or so to earth.

Funny, I get more alarmed by light aircraft. It's like... I can see from the outside that it's just a bunch of sheet metal stuck together with rivets. It's not even particularly neat, either — there are gaps and uneven overlaps and stuff. And we're going to get into that thing and fly it up into the sky? Ummm... okay, I guess! 😬
