There's also the separate (but related) matter of what happens to all that stuff that rockets spew into the atmosphere on their way up, and material shed during re-entry when satellites come back down. (see, e.g., https://t.co/KbNrAW1Qij)

Burning aluminum satellites in the atmosphere will likely have a similar effect as geoengineering,..https://t.co/snazT9K7Lz.

#385tech The private sector's space race for mega-constellations could cause satellite collisions and impede astronomy; private-sector deployment has accelerated rapidly in recent years. How can we curb this impeding disaster? https://t.co/OMigL6RUQh

@torybruno Interesting, thanks😉- treaties agreed before, rather than after entangled sovereignty claims result in a tragedy of the commons would be ideal. Competing interests (ie astronomy) would have differing views on a foreseeable limit to the real est

(6/7) Mandating controlled reentries into remote areas of the ocean is currently the best way to reduce casualty risks. Complete atmospheric demise may also be possible for some rocket bodies. However, this doesn’t address all environmental risks. https://

Starlink is not in geo, but instead LEO, similar to where $ASTS will be. Observers do not have to look out too far to see a quickly escalating problem with LEO real estate and lack of regulatory oversight https://t.co/lcYjyCrm1I https://t.co/qJRtIBb38v

@_TheGeoff The concern is about changing the radiative balance of the atmosphere. Injecting alumina at high (~many 10s of km) has been proposed as a geoengineering method. Here’s another ref I was looking for earlier (specific to reentries). It’s not payw

Recently, 40 of 49 Starlink satellites got affected by increasing atmospheric drag induced by a solar storm reaching us at the time of sat deployment. Those 40 satellites will reenter the Earth's atmosphere. I then thought of the Boley & Byers paper.

@erasmix You are? #SpaceX #Amazon #Boeing all want mega constellations. It, unfortunately, will happen and then we lose access to space. Too bad they don't wait to figure out how to clean up LEO first. Read the following: https://t.co/sJWfokjDt5
