Why?
My impression was that the low orbits used by Starlink and similar are the best place for this since it will all naturally deorbit on short timescales.
It's just space who cares if we clog it up some with more useful things.
- verdverm 5y ago"clog" is relative here and space (including LEO) is huge
- toxik 5y agoWe once said the ocean is huge too.
- verdverm 5y agospace >>>> air >> ocean > land It is worth considering the ocean is ~2d while air and space are 3d.
- pdq 5y agoThe ocean is most certainly 3D. The surface is 2D.
- verdverm 5y ago~2d was intended to imply effectively 2d for human activities, even airspace is probably closer to a layered 2d cake than true 3d like deeper space. LEO may be closer to an extension of airspace due to orbits and gravity. Still, due to the exponential growth with respect to the radius, there is significant room in LEO compared to anything terrestrial.
- dylan604 5y agoHow does this differeniate space and the ocean in your mind? Humans cannot survive in either without some sort of vessel to provide a suitable environment.
- verdverm 5y agoMy GGGP point was about "clogging" space with satellites, not about habitation. Space is so large that 100K's of satellites is still not clogged. I believe the SpaceX and AWS constellations are planned to get us pretty close to 100k iirc
- aidenn0 5y agoQuadratic growth, not exponential growth.

- verdverm 5y agoI think it's cubic because they sum, polynomial either way, without considering other factors like potential for increased density the further out
- aidenn0 5y agoRight; I meant the number of satellites supportable at any given altitude, not the number of satellites supportable up to a given altitude.
- colordrops 5y agoAnd there's nothing in space that supports life or the ecosystem.
- verdverm 5y agoDepends, could our increased use of satellite based sensing be used to support and improve the terrestrial situation? Is the tradeoff worth it? It is certain that your life today would not be the same without GPS, so in a sense it does support it.
- colordrops 5y agoI mean there's nothing in space that we will damage (unlike the ocean) by using it. I'm all for utilizing space.
- Denvercoder9 5y agoIs there anyone claiming the ocean is full?
- colordrops 5y agoWhat do you mean?
- switz 5y agoNot OP, but I can think of two reasons – too many LEO satellites can actually hinder views of the night sky[0] and additionally, the risk of kessler syndrome[1]. I'm in no way equipped to give a scientific risk assessment of either, so I'll defer to others to share if they feel it's major concern. But whether these are present issues or not, they're worth considering and thinking about as we move forward with more LEO deployments. The latter issue especially, given that once it occurs, it'll be extremely difficult (nigh impossible?) to rectify in short order.

- logicx24 5y agoAmazing, we now have sky NIMBYs complaining about satellites hindering views.
- dylan604 5y agojust because you live in a place where you can't even see the night sky doesn't mean other people should be robbed of their view.
- Lapsed 5y agoNo one lives in a place where they can see starlink satellites with their naked eye once they are in operational orbit.
- BenjiWiebe 5y agoI'd be in favor of requiring all city lights to be turned off after 7pm so I could see the night sky better in my rural location. (/sorta s) A small city 40 miles away hurts the view far more then the Starlink satellites do.
- mgraczyk 5y agoThe night view is a potential issue, but Kessler syndrome is not. These satellites will decay on extremely short timescales. Until many of them start blowing up and launching debris in higher orbit, we don't need to worry too much about this.
- olivierduval 5y agoBecause you think that being able to read twitter between two ads is "more useful" than watching a pure night sky ???? Maybe you should think about what is really "useful" for you... and what other people find "useful"
- Lapsed 5y agoYou can't see starlink satellites with the naked eye once they are in their operational orbit. I'm sure many people find it useful to be able to attend school: https://www.pcmag.com/news/native-american-tribe-gets-early-access-to-spacexs-starlink-and-says-its https://www.pcmag.com/news/native-american-tribe-gets-early-...
- olivierduval 5y agoSo what is https://www.youtube.com/watch?v=pgysWWwESfU&t=2s https://www.youtube.com/watch?v=pgysWWwESfU&t=2s ? And it's only with 700 satellites around the world right now...
- Lapsed 5y agoThis is shortly after launch while the satellites are still tumbling. Within a few days they align themselves so that their sunshields reduce their brightness and over the next few months they will raise them selves to their operational orbit.
- ppqqrr 5y agoI think people who have night sky views pure enough for satellites to become a nuisance is probably in the global minority. One might even call it a privileged pov, given that most rural inhabitants of this planet struggle for basic network connectivity needed for their livelihood and the education of their children. I respect your sentiment, though - ultimately, the question is not whether we should do it; it’s who’s gonna stop us.
