- mrmlz 3y agoWell operating a highly custom and very expensive is going to have astronomical operating costs as well.
- Timshel 3y agoResurfacing is an operating cost it needs to be done periodically.
- ars 3y agoI'm going to need some more info on that, because that doesn't sound right to me. There's no way they are regrinding and resurfacing the mirror periodically - cleaning, sure. But redoing the surface? I'd like to see more info please.
- dylan604 3y agoJust go watch the referenced link. It is a very informative video. It's only the top response of this whole thread, but just to make it convenient[0]. I can only lead you to water. I can't make you drink it. Continuing to refute it after that just let's us know exactly what you're about [0]https://news.ycombinator.com/item?id=38092084 https://news.ycombinator.com/item?id=38092084
- ars 3y agoAs requested, I drank, and I saw the part about them refinishing the top surface layer. As I suspected it was not them redoing the glass, rather removing the aluminum and redepositing it. The perfectly shaped glass is the expensive part - coating it is not the expensive part. So despite drinking, I did not get my answer on how this telescope costs $100million a year to operate.
- dylan604 3y agoWhat part of my comment suggests I was talking about manufacturing costs?
- ars 3y agoThis part: "quality material fabricated to be installed"
- dylan604 3y agoBut they do this operation every few years. It is an ongoing process of installing the aluminum surface. Applying/Re-applying maybe words better fit for your understanding?
- ars 3y agoIt's nice to change your words after the fact, but taking your words, as originally written, your response to a question about operations was a reply about manufacturing. Additionally it does not costs millions to operate this resurfacing machine. Building it? Sure, I could see that. But running it? No way.
