This is how basic science works. Push the boundaries, let someone else figure out how to use it practically. Who knows. Maybe the earth runs out of water in 2530. Someone scans the old hubble photos for a water rich comet and they go get it. If humans didn't do basic science like this we would still be living in caves.

It also takes years before a discovery is ready to go to market. It took 11 years to make Blu-ray, and we already had blue lasers, and led lasers. Not to mention that the only real difference between DVD and Blu-ray is how narrow the beam is, and the code to make the laser read and write everything closer together. The first fridge literally took 80 years from it's invention till you could buy one in a store. And what we now call quantum mechanics actually got it's very earliest start in the middle of the 1800's. It's all important to know, because we don't know what we'll be able to do with what we discover now in the future.

Jon Nunn To clarify, the corrective optics have been incorporated in all the new instruments since COSTAR. COSTAR was made for the instruments made on the original optical baseline. Once the last original instrument (an FGS) was removed in 2009, there was no need for COSTAR. This was good because it freed up another axial instrument space and so the Cosmic Origins Spectrograph took its place.

Maybe he could do a vid on the Zandmotor or the "room for the river" project as well? Idk how well his water-works videos do.

[@vdevov]

I’m amazed it was never mentioned that many of the colors in those incredible photos are not “real”. The wavelengths are real; however, a massive part of the photo processing is artistic. It’s not done for science, but it’s done for publicity. The scientists don’t look at those colorful images. They look at the different specific wavelengths they’re interested in. Humans have no perception of what X-Rays, microwave, infrared, UV wavelengths look like, because those are not in our visible spectrum. Those wavelengths, we normally can’t see, are given false representations when the images are stacked from Hubble.

[@steveluke2395]

[@thomaswalz3515]

I have no problem with the augmented images... and I appreciate the merger of the arts and science.

[@paulwalsh2344]

@ VdevoV Well I'm glad you brought that up too, but it's not just as simple as being artistic, or for publicity at all. That attitude simply reinforces the opinion that space images are "fake". The Hubble Pallet is a method of presenting much more of the totality of a celestial object's features in one amazing image. All objects in space have their natural colors. Unfortunately except for very close up or extraordinarily bright objects we can't see with our eyes or even with optical telescopes highly saturated images (vibrant colors). With objects with low surface brightness or diffuse features, what we can see with our eyes or optical telescopes usually is only practically black and white (or actually green due to the Purkinje effect). Often features that are very definitely there, therefore, are extraordinarily dim or nearly invisible. With Hubble Space Telescope, details that are more prominent in UV or Infrared are also added to the raw images. The majority of the Hubble Space Telescope images we in the public see, are taken using narrow filters that capture sulfur, hydrogen and oxygen, each filtering and therefore "focusing" on features that are richer in those component elements and by assigning a color (red to sulfer, green to hydrogen and blue to oxygen) the composite image shows the details, that I stress ARE THERE just not what our eye would pick up if we were there at a distance where the field of view would be similar. A lot of the detailed features would be there, visible, just in the same green, purple and reds and indigo like what we would normally see like from under our aurorae here on Earth.

[@vdevov]

​@@paulwalsh2344 By no means am I diminishing the beauty and wonder that the Hubble is able to uncover from our universe. I never said the *images* were fake. I just mentioned that "many of the *colors* in those incredible photos are not 'real'". The black and white photos themselves are real. The stacking of wavelengths is real. The full color representation is what I'm referring to, which *is* artistic. ANY image that gives visible light representations to wavelengths outside of the visible spectrum are called false-color images. I understand the narrow band filters very well, but those, (one not even in the visible spectrum: Oxygen), as you said, are either slightly shifted, balanced or boosted. But all those wavelengths are given approximate representations, which, while still being "real" is, well, artistic. Just the term Hubble palette shows that for many wavelengths, there's are normally standardized colors to match to specific wavelengths. They use narrowband imaging to get through the dust of space. All light captured by the Hubble may be real, but the visible color representations created by the ones processing the final photos are not. Plus you only mentioned those specific wavelengths, for normal narrowband imaging. The Hubble has the ability to image 100nm to 1.8 μm. Anything out of visible wavelengths, will also be given false-color representations.

[@amicloud_yt]

Aww... Simon totally skipped over what actually went wrong with the mirror! The company that ground the mirror had, of course, equipment to measure the dimensions of the mirror being produced. NASA decided that they needed to build a special testing tool to verify the dimensions and qualities of the mirror in a different way. The original equipment indicated that they were right on target and the mirror was perfect, but the specialty equipment from NASA reported that the shape was wrong... So they trusted the NASA tool of course. But... Obviously,. it was the NASA tool that was wrong. The fix, COSTAR, was basically just an image processing unit that was, thankfully, able to correct the small issue with the mirror.

[@fraserhenderson7839]

I wasn't aware of the specific story but I knew there was controversy during the polishing. Sometimes this channel goes a little "Vague Scientist". The "rescue" COSTAR mission with Storey Musgrave et al was heavily televised and completely fascinating for me

[@tangydiesel1886]

@@xiro6 you are correct. I've read both versions as well, either a design flaw or calibration error in the instrumentation. I oversimplified what I said.

Interestingly enough I have a special keychain that was issued by Perkin Elmer, the maker of the mirror & OTA that had so many early issues, in the early 80’s before the launch. I still have all the original packaging. The pamphlet that is inside goes on at length about the upcoming 1984 launch, which of course did not happen BECAUSE of Perkin Elmer.

I agree that Hubble should be preserved as an historical object, but I think that moving it to a higher, low maintenance orbit would be cheaper and safer than returning it to earth. It might actually still be useful.

[@BIGJATPSU]

@@theobserver9131 while it certainly is still useful and will remain so even after the JWST launches, if it ever happens, I don't know if it'd be possible to boost it to such an orbit successfully for less cost than brining it home. Not only would you have to push it out farther but also speed it's rotation around the Earth slightly to help counteract atmospheric drag. As it was designed with very minimal booster technology, this would all have to be done by other means such as an attached engine of some sort which would further complicate the issue. I think the best thing would to bring her down and preserve it for all times. But your idea of a higher stable orbit is DEFINETELY the way to go for all future space telescopes starting with Webb and hopefully Hubble's true replacement in the decade to follow. This would increase the clarity of the images slightly and we wouldn't have to spend money on any recovery just upgrades. 😉

We need to refine our models and this satellite, and others planned, help us do that. By refining our models, we learn more, and make better tech to enrich our lives. Also, make more space content please...

I worked in the clean room where Hubble's frame was built (Sunnyvale, CA, Moffett field). The building is still there and , AFAIK, is still a clean room. Is it large? No, it's massive. You can easily fit a football pitch (or field) in it and still have room for grandstands. After Hubble, it was repurposed as an all-in-one satellite manufacturing facility, with separate testing rooms for radio ranging, vibration, and a vacuum chamber. Good times.

I don’t get how people aren’t interested in outer space. The universe holds the answers to every question we’ve ever asked, and an infinite number of questions we will never even think to inquire.

[@CamMackay96]

I had an ex-girlfriend who *despised* space talk like this, much to my dismay. She said it sent her into an existential panic and she didn't like thinking about the true massiveness of the universe. I can only imagine its the same for other non-scientific people 🤷🏽‍♂️ Fun story, she once had a full blown argument/breakdown when I tried to explain that the periodic table included every possible and potential element found throughout the universe... try explaining that one in detail to someone studying politics 😂

BART - Bay Area Rapid Transit. It's a train system that covers parts of the San Francisco Bay Area, including going underneath and across the bay. It was initially made in the 60s or so and there are new trains being put in use now.

Thank you so much for doing this video on Hubble. I was hoping you would. It was extremely interesting. Cheers, Steve

[@magikworx3748]

I used to work with Story Musgrave, one of the guys who space-walked to fix Hubble. He'd be a fascinating subject for a video. He's done a ridiculous amount including being the only guy to fly on all 5 shuttles, being the first to space walk, being the second oldest astronaut in space at 61(oldest at the time), as well as breakthroughs in medicine and agriculture.

[@mgabrysSF]

Books on the subject (and repair missions) showed that 'just the mirror' wasn't an issue. There was a 'twang' picked up by the solar arrays as they crossed the Earth from shadow to sunrise. The thermal shock caused vibrations which would continue for quite some time. These were replaced in the first repair mission with the corrective optics package.

[@belland_dog8235]

It's so annoying when people get mad about the costs of space technology, and rockets, and etc. Yeah, it's expensive. Tens of billions of dollars is a lot, and the risk is high. But it pails in comparison to what we spend on the military, YEARLY. We could fund dozens more space projects, but no. We need more aircraft carriers that we don't use for anything but a dick measuring contest. We could fix the terrible road infrastructure, but no. We need more dozens of more military jets for the war we shouldn't be in. We could pay for medical bills, therapy (physical and mental), and overall health needs of veterans, but no. We need to spend hundreds of billions to send them into wars we, again, don't need to be going into. Anyway, that's my rant. Thanks for coming.

[@bobbysenterprises3220]

Thanks for this. The primary mirror for this scope was manufactured less than an hour drive from where I love. It was a huge dealkxallu when it was launched while I was in school

So... my grandfather was a genius, but is best known for his work on cameras. Following WW2 he got a job with JPL. While working for them he made many cameras, and many of them are still working. While my grandfather unfortunately passed away in 1992, never having seen his greatest work actually work... his most famous cameras are located on the Voyager 1 and 2 probes and on the Hubble Telescope.... so... yeah I love this video.

Do you think you could do a video on the Nevada-Class Battleships as both ships had interesting careers. One of which USS Nevada tried to escape Pearl Harbor, fought at D-Day , Iwo Jima, and Okinawa, and survived 2 atomic bombs. I would say that's a mega ship. Awesome video. Hope more videos are coming.

You should do a biographics on the men you named at the start. Oberth was the man who worked out the Oberth effect, Goddard invented liquid fuel rocket engines and multi stage rockets, and Tsiolkovsky worked out the mathematics of getting to space known as the Tsiolkovsky rocket equation. These three men along with the French man Esnault-Pelterie are responsible for starting humanity on the road to space!

One of my favorite quotes came from the character Sam Seaborn in the TV show West Wing. 'Cause it's next. 'Cause we came out of the cave, and we looked over the hill and we saw fire; and we crossed the ocean and we pioneered the west, and we took to the sky. The history of man is hung on a timeline of exploration and this is what's next.

[@DaveNarn]

Wow, I had no idea of the challenges Hubble had to overcome before launch alone! Looking forward to your James Web telescope video.. if it ever launches!!

[@LuigiStyl]

It is actually astounding how much went wrong with the telescope compared to how well it currently works. I wrote a report in college about how terrible the construction and deployment of the telescope went and why politics, jealousy, mismanagement, and budget cuts interfered with the original design and construction plans. They likely underestimated the original cost by about 50% (so it would have cost twice the original estimate) should things have actually gone as planned. With that it might have even launched on schedule too. However it did not and it had so many problems along the way. For something that cost nearly $5 billion, and was not intended to last as long as it has, it is doing very well especially considering there is nothing else in space that can quite do what Hubble can today. I would highly recommend people read up on the history of the telescope's production after this video. There is so much more that Simon did not, and realistically could not, cover while still being able to keep the attention of his viewers.

[@TheDragonaf1]

11:53 Fun fact when Hubbell's lenses was misplaced they used algorithms to correct the blurry image. I wrote my master's thesis is those class of algorithms.

[@scottM278]

I know 4 people who used to work for a government subcontracting company called CUBIC in San Diego, California. They were all machinists and made some of the parts on the Hubble telescope.
