Easily solved in software by removing the small part of each frame that has a satellite in it. Satellite tracks are completely predictable. This is not novel.

- JBorrow 6y agoPerhaps true for amateur astrophotography but not the case for professional astronomy. Please see reporting in e.g. [1] and [2]. Note that simply putting telescopes in space is not a viable solution to these problems.

- gpm 6y agoA few particularly large and particularly sensitive telescopes will have problems not easily resolvable by software, the vast majority of telescopes will not.
- dx87 6y agoThat actually sounds worse. Large expensive telescopes will have issues, but amateur astronomers will say there isn't any issue because the pictures they take with their smaller telescopes are cleaned up with software.
- gpm 6y agoArguably so (I'm going to generally stay out of value judgments), but do note that it's not all large expensive telescopes, it depends on the telescope.
- shadowgovt 6y ago... which has always been true. Several observatories were built near cities. As light pollution from terrestrial sources have increased, they've found their expensive optical telescopes become toys, and have moved their scientific collection utility over to radio.
- JBorrow 6y agoYes, these are massively important to professional astronomy and our understanding of the universe.
- shadowgovt 6y agoSuch concerns should probably be balanced against the potential the launch capacity of Starlink represents. I'm looking forward to someone launching a satellite telescope network with the collection radius of an Earth orbit.

- Kye 6y agoSomehow I get the feeling people who do this professionally understand what's possible and what effect this has better than you.
- gpm 6y agoThey undoubtedly do, but this is an opinion formed by talking to people in person in the industry. Random twitter users who manage to get there tweet on HN is not even close to an unbiased sample of professionals in the industry. My sample undoubtedly also has its biases, but is not selected for sensationalist views at least.
- Kye 6y agoThis is "I talked to some people" vs the linked tweet from a person in the industry. I think you can understand my skepticism. I also understand you probably don't have a convenient way to prove your side of it.
- tenuousemphasis 6y agoThe person who posted this tweet? I don't think so. They also said this gibberish: >Space junk. There HAS to be another way to improve internet communications, does Humanity and planet Earth's livestock need this (5G)? Really?
- Kye 6y agoSometimes people with real domain experience on one topic try to have opinions on other things. It doesn't always go well.
- abduhl 6y agoYet another physical layer problem conveniently solved by a software solution (coded over the weekend, of course)!
- jcun4128 6y agoDid have a thought about a physical device/notification system that lets you know the sky is clear, would be interesting to work on that the tracking/predicting position assuming data is available.
