[@StarTalk]

🔭 The Chandra X-ray Observatory has been crucial in space imaging. What are your thoughts on its potential decommissioning?

[@solertree8653]

I am decidedly unhappy with it. Considering the budget the US and other countries that have space programs have, and considering what they enthusiastically spend on things like the military and all of its various branches, it is iniquitous that scientific discovery should not be funded. I think a solution to this problem is to place the results of the Chandra Observatory squarely in the public eye, and let people see what they'll be missing out on when it's no longer there. As with Hubble, I believe the public will do the rest, because curiosity is an inextricable part of being human.

[@Gielderst]

Epic explanation Neil. Always stay this awesome. These telescopes are truly incredible and have served us more than well. I hope the JWST uncovers even more of what's out there in the vastness of Space-Time.

[@theduder2617]

We can afford to fund that entire branch of discovery and so much more. Those currently in positions of power/influence have pressured those in positions to make the decisions into bailing on knowledge/education. The money they want to choose not to provide will still exist and I promise, will be spent. Spent more than likely on efforts to continue devaluing knowledge/education. Spent on their current efforts at eliminating women's rights to life itself. What our government could fund would fill this comment thread. This is a choice being considered, not any form of a lack of funds. A major reason why we are not supposed to vote in those who do not have us, We the People as their priority. A major reason why only actual qualified individuals should be allowed to work for us, We the People.

I found out yesterday that my wife has never been to a planetarium. I grew up outside of Atlanta in the 70s and early 80s and was so fortunate to benefit from the old model of public education. We took field trips. We had speakers from all different walks of life come and talk to us about life after school. We had mock elections for each major election while I grew up in grade school. We had music and theater classes, while we kept pace in both science and math, since we weren't subject to the common core's depleted approach. We have a 2 year old boy and a little girl next month. We might not have the same education system we used to, but my wife and I are products of that era and we have every intention of carrying that spirit forward with our little ones. I can't wait till my boy can stay still long enough to enjoy the planetarium. He already loves stars and the moon. Thanks Neil for always encouraging us to keep looking up.

Our primary school was only two big rooms, a study/storage room and principal office basically. Once I moved them, he said you have this week to find what you want to use for your project. I opened one and it was stuffed full of images, photos and all manner or stuff from NASA for my school project. Was only supposed to be a 10-20 minutes brief of my project on satellites to all the planets and such, an hour and a half later the principal said, sorry to cut in and stop you there, but it's lunchtime and we need to go outside ;) Was the best thing for me at the time, I didn't realise the other kids at school also loved space, who knew.

Subrahmanyan Chandrasekhar after whom the the Chandra X-ray Observatory is named, was a brilliant mathematician and astrophysicist from India. A Nobel prize winner (in the footsteps of his uncle C.V. Raman) and life-long professor at the University of Chicago, Chandra provided the mathematical functions for stellar evolution using Einstein's special theory of relativity and was one of the early proponents of Black-holes. His discoveries were initially snubbed by likes of Eddington but eventually proved to be correct and became instrumental in understanding a star's life cycle. It's only apt that the first in-orbit X-ray Observatory was named after him!

We are getting so close to understanding where we came from and how we were created. The idea about how we are expanding our ideas makes so much sense. My cousin worked for area 51 and NASA n I know these ideas are becoming more true each day.hes a chemical physicist working on the idea of understanding protons and matter. I know these ideas are definitely the truth because there is so much out there we don't understand. Even though we are advanced beings we don't have enough understanding to where we are future wise. Just like the guy who worked for NASA who came out and said we now have the technology to take et home. We have definitely found ways to understand things we just don't know about. We live in a world that has almost become like a scientific movie. We are getting oh so close to opening up ideas and working with them to open up doors to knowledge of the universe. Every little satellite we send into orbit is finding new anomalies that are happening In other worlds. If we can see stuff happening 7 trillion miles away how can we not know what's going on in our own backyard. The brain can understand and perceive new things that we just don't understand, that is why we have accomplished so much space wise and our finding new ideas and reasons that we are advancing as a race. This is being held from us by the government so they can track what we do and where we go. They feel so much more confident if they know what's going on at all times. This might be the reason we are so limited to the truth and knowledge of the cosmos.

However to service and retrieve satellites and such in orbit we don't have a good replacement or replacements yet. A starship variant may one day do some of this, perhaps all or at least all through variants. Right now there is little we can do to fix things in orbit. We spent a fortune on putting the Hubble up. However there was flaw in it that would have ended it's operation before it began quite likely, except we sent a shuttle up with a fix and have explored the universe in the visible light in an extraordinary and beautiful way for decades since. Something like that happen today and years of work and billions of dollars get flushed and many have a large chunk of their lives wasted. Spend 5 years of your career on a project that failed and even if your next job has heard of it, you've just labeled yourself a failure to them. So perhaps worse than a waste.

1.) As we move farther and farther into space, we don't actually have a space network. we have telecommunication satellites around the earth. but we don't have one lets say near Neptune that could help relay signals from Voyager. We could use satellites around Mars or Venus that would aid in communications when a probe moves to the far side of the planet. For instance, if we tried to land or explore an object on the far side of the Sun, we would need a direct line for communications. We need to boost signals as much as relay signals...right now if we tried to put something between Earth and Voyager, Voyager is moving away so fast that we could never reach a midpoint between Voyager and us. But the benefit would be that we could still pick up communications. 2.) I noticed that you used the term observatories. But, the International space station does not have its own integrated telescope system. Could some of these modular telescope systems be realigned, repurposed or coupled together? The benefit would be like having a manned telescope in orbit. From your description, we go there and repair the technology. But we don't go to the telescope and physically experiment.

I know what everyone says about the cost of the Shuttle, but I feel that the lack of improvement and discontinuation of the Shuttle was a major setback and unfortunate for future missions for the space telescopes, science and the US. Just my opinion!

[@pacosamo]

So excellently explained. Perhaps the US congress could use subscribing to your channel Neil.

I love that the Hubble had astigmatism, and we made glasses for it.

The lead scientist was the esteemed Mr. Magoo.

The shortening of Chandrasekhar to 'Chandra' also happens to mean the Hindu God of the moon or literally 'bright light' in Sanskrit! Love your vids btw :) ... Edit: I wonder if that's where 'candle' or 'chandelier' come from too...?

[@TonyFarley-pv3nk]

All that cracks me up because we have this treaty and then they're all being prepared by it

[@chazhoolio2336]

As a planet all nations should contribute to costs forget boundaries

[@MK.__]

So greatly explained💚

[@hellomrsalman]

I hope ISRO will help in funding n in manufacturing issues with NASA n replace Chandra X-ray Observatory to a new modified version of it because we need this X-Ray detections in future. I mean thanks to Chandra Observatory we could get a picture of a Black hole ❤ my goodness could u feel this 🤩

[@j3cosmos]

Keep looking up!

[@JoeGamesAndSocializes]

@startalk you guys should do a video on the Aurora Supercomputer in Illinois. It’s available to the general scientific community and is solving problems/being used for researching cancer, cosmology, and brain mapping, just to name a few!

[@shredder3440]

ah yea Werner Vaun Braun, hung his slowest workes and left them hanging as an example to the rest of his " employees" a true hero

[@johnmccombe6342]

You all should get Dan Durda on to talk about the D.A.R.T. mission!

[@YT2024Hayward]

Far All Mankind tv show on AppleTV is one of the best shows about space exploration. Seriously!

[@nathanmoore1893]

Love the 4K.

[@mikevc5415]

Love these videos! Thank you so much ❤

[@skipodap1]

Great video

[@don63]

Have to keep CHANDRA operational.

[@MrYTGuy1]

this is the part in history books where the focus shifts back to Europe for all the innovations that will continue to progress humanity. america will have a brief 250 years of relevancy in future history books... gg

Shooting ourself in the foot with the cost of education

[@bebbcorpharpery7331]

For the price of a fighter jet we could have a looking glass into the universe that doesn’t hurt people.

[@Ghost_Recon_Actual]

Is there a way for astrophysicists and space enthusiasts to unite and urge the government to continue funding and maintaining telescopes? This is crucial for expanding our understanding of the universe's origins and the future of humanity on the tiny blue dot we call home.

[@jeffreyhampton9130]

NDT- what's the lead time to use the various space telescopes?

[@gilbertreichling]

Thanks for your scripting tips! How do you usually decide which details to include in a script? 💋🔥

[@oddyneo]

Thanks for this.

[@Nedski42YT]

There is an observatory in Connecticut that has a bit of the Chandra mirror on display.

[@jeff_chillin_ez]

Wallpaper and screensaver. Straight Facts!

[@swervbe]

Not of low or high energy xray pictures though!

[@muggs105]

Hey, Neil, great video, huge fan of space, i got a question about telescopes now that you say that some get repaired, others decommissioned, etc. is there a way to add not only visible spectrum of light into one of those, but also other types of light at the same time?

[@R2Zmedia]

Sad to hear this, we need to improve our understanding of everything and this will leave a glaring hole in our ability to do so.

[@christopherboisvert6902]

We have to continue our journey on exploring the universe. We could solve a lot of our problems with better understanding of the universe.
