I have worked with "pretty accurate" machines and electronics my whole life and career. I guess I really didn't have the range on "really, really accurate" until I started reading about telescopes' optics, (earth bound and space bound). Then there's aiming and tracking. The physical and optical accuracy telescopes are built to and can achieve are barely imaginable. Large machines, some parts with nanometer accuracy is astounding. Planned, designed and built by teams of brilliant people. Then managed and operated by teams of brilliant people. I'm just amazed.

The hardware is designed and made by engineers. The observations are made and analysed by astrophysicists. However, it is the people who determine how to orbit a point in space, tune up the hardware and schedule the program to maximise the 'information per observation' who count as "rocket scientists" in my book. That said - there are about 150000 people on the planet who should be feeling pretty proud at the moment.

Seriously. I work with radar and have to do phase alignments by hand-trimming coax cable to within a few tenths of an inch, for frequencies with wavelengths a couple 100,000x longer than the light they're aligning MIRRORS for, from a million miles away. I just can't comprehend that.

Wow... while I already knew the struts were somehow involved in the creation of those spikes in the resulting image, I'd never seen such an intuitive illustration of _how_ that worked! This made it so much easier to understand, particularly when you provide such a comprehensive explanation (even including the extra strut offset at the bottom). I'll definitely be sharing this the next time this topic comes up. p.s. I know I'm just gushing with positivity here, but I can't leave without the obligatory "I'm so stoked to see JWST's first scientific images" 😄 Even the initial _test_ images are incredibly fascinating.

Thank you for explaining the streaks coming off the stars!! The thing I’m excited about is that I remember hearing it would take 6 months to adjust the mirrors alone. It’s been 3-4 months since launch and they’re ALREADY aligned. It seems that the engineers gave a conservative estimation, which I’m grateful for because anything done quicker than intended means more fuel for science!!
@cykkm
2 жыл бұрын
They saved the best possible amount of fuel they didn't even hope for during the Earth orbital insertion, so precise it was. If you watched the launch, it was unusual how often did they read the planned trajectory deviation, and you could feel tension in the air. The computed planned trajectory itself was unusual, it had an altitude dip-I have no idea why did they do that. They had extra spare fuel capacity in the launch vehicle for the mission, so I'm guessing that they traded efficiency for precision with this unusual launch trajectory. The Ariane folks know their rocket so intimately, and many kudos go to to them for prolonging sciencing lifetime of the telescope by many months!

No, the schedule was always that it would take 6 months to commission the telescope, with mirror alignment being finished after about 3 months. So they're on schedule. Next comes 3 months of instrument calibration.

Hi Christian, thank you, this is the best high-level explanation of the full alignment process I've found! I'm not even an amateur astronomer, and the other sources I read or watched either simplified it beyond useful, or started way above my head (“the public APT file of the fine phasing is fun to check out” sounds Chinese to me; I believe it's fun, only not to me...). You're an amazing teacher. Your short lecture is the perfect balancing act of finding that focal point from which the rest of us can dig deeper if we want. My next pit is the nm-precision actuators that can work smoothly in the hard vacuum of space at 50K, probably not allowed internal heaters. For the lifetime of the Webb. And it's not something you can rock back and forth if its seizes, as they often do to mechanisms in space. A technology indistinguishable from magic! They must be using basilisk saliva for anti-seize lubrication, methinks... And--how come that _The Sharpest Image the Webb will have Ever Taken_ is still not in your merch store??? I envy the little shiny Webb you wear, and want a bit of the Webb for myself, too! It may be too complex for screen-printed fabric, but I guess at least stickers and mugs can be done. And the full image whose lower 2/3 you show at 6:48 is simply dying to jump on and cling to a black T-shirt!

OMG. Where to begin. Firstly, thank you for updating the status of the JWST. I am in awe of your ability to explain things to such a lay person such as me. I probably understood 25% of what you said. Another watch might improve things. It isn't your explanations, it's my limited knowledge in the field of astronomy, I am sure. That said, I am even more in awe of several things about the JWST. The technology, the ingenuity, the ability for humans to understand the physics behind all of this, the obstacles that must have been conjectured and later overcome because of how light, space, materials and things work. I understand that there wasn't just one person who solved the meriad of problems this sort of telescope presented, but I am still amazed that any number of people could come together to create it, launch it, get it to where it needed to be, then operate it remotely to give us the science humans so crave. (Out of curiousity, how long does a round trip of instructions to response take at the distance that it is?) I can only say, that I appreciate the effort was made. My exclamation 'OMG' and 'Wow', just doesn't seem to cut it, but it is all I can say. I am so hungry to see the first images come June.

What excites me most seriously are the infrared images of stars at the galactic center smudging and blending together during their orbits around A*. What will happen when we look at A* with the Webb is a total clearing around A* and probably the ability to see the accretion disk surrounding A*. Which at this time is invisible because of a lot of factors. Primarily the intervening dust and gas. What will be even more spectacular is the Japanese sighting some distance out from A* where was found very high speed gas, that when looked at with WEBB-T will probably show its accretion disk also because of the deeper infra-red imaging ability of WEBB-T. MY prediction is it will be an intermediate size between A* and recently found cluster BHs being in the 500,000 solar mass range unless it's trajectory is straight towards A*. In that case it could be even twice or three times the mass of A*. My reason for this to be so is it certainly will not orbit A* if more massive, as A* would orbit it if much more massive. With WEBB it will be very interesting to track it's, (the Japanese black hole), position and trajectory and that will only be possible with WEBB observing it's accretion disk in high resolution.
