[Bonus] How Do Satellites NOT Crash. And How Can We Keep It That Way?
As we put more and more satellites in orbit, chances of them colliding also increase. How can we manage that? How can we make sure that Kessler syndrome won't happen and keep all those satellites from destroying each other? Finding out in this interview.

I don't get it. If you're fine with learning to code from an LLM then why even code yourself and not just tell the LLM the vibes and let it code for you? And if so why not skip the code entirely and just let the LLM decide how to solve the problem itself? And here we get to all the AI slop that's literally taking your job. So where do you draw the line? (I personally frown upon any interaction with an LLM and try to limit mine as much as possible, but it seems like you're more moderate than I am so I'm curious to know your opinion on the matter)
Do we know, what is the distance limit between two satellites, when they have to do the evasive maneuver?
Thank you ! I loved this interview. Very informative and I do feel better about the space junk, per se, and I’m hoping we can globally agree on space policy for all of its components as Dr Dolan outlined. Keep up the great work!
Loved this interview!!
At the start of the Starlink Constellation project Elon was asked about the dangers of collisions but he dismissed them saying it was like a few thousand cars driving round the Earth. I thought at the time, look how well that turned out!
This is my 80th year of life. As I look at the world around me, it is easy to experience frustration, and to abandon hope for the future. However, as I watched this interview, I felt such optimism for the future. Sincere thanks to both Sidney Dolan and to Fraser for sharing your enthusism for life. I spend my days here in Finland working with wonderful children, and I hope that I can convey such enthusiasm to them, as well.
Awesome show and interview! When you started asking about how enthusiastic amateurs could get involved, I wish you had asked whether it is possible for amateur astrophotographers to participate in tracking objects in orbit. I know from personal experience how many satellite tracks show up in my "long" exposures (60 to 600 seconds), and I also know amateurs can and do make contributions to both variable star and exoplanet astronomy. But can amateurs make a significant contribution to the tracking of stuff in orbit?
Thank you Dr. Dolan! Another great video where I was able to learn something.
I looked up a term she kept using which was new to me even though I was getting gist of its likely meaning: ephemerides (noun, plural) A table or data file giving the calculated positions of a celestial object at regular intervals throughout a period. In case it helps anyone else.
I’ve seen the term many times but I’m happy to hear someone pronounce it!
