C.<a href="https://climatejustice.social/@Brad_Rosenheim" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@Brad_Rosenheim</a> Except ... when this claim (not about the satellites re-entering, just the amount of damage they cause to the atmosphere) started circulating some months back, I read an article (somewhere...) that analyzed the amount and type of matter it would distribute, and it pales in comparison to the amount the earth receives in "space dust" and micrometeroids every day.Best figure I know of for the mass of "normal" space matter hitting our planet is 5,200 tonnes / year: <a href="https://www.scientificamerican.com/article/antarctic-study-shows-how-much-space-dust-hits-earth-every-year/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.scientificamerican.com/article/antarctic-study-shows-how-much-space-dust-hits-earth-every-year/</a>The current Starlink satellites are "gen2 mini", and are 740 kg. So you would need to de-orbit more than 7,000 of them every year - not 4 per day - to even match the natural space dust falling on earth. Except it's even worse (for the argument) than that, because 740kg is their launch mass, including all their maneuvering fuel/gasses, which by definition are gone before the satellites are deorbited. I don't have an exact figure for how much mass the fuel accounts for, but it wouldn't surprise me if it was more than 25% of the mass of the spacecraft at launch.The residue left in the atmosphere doesn't seem to be a very big deal.<a href="https://mindly.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://mindly.social/tags/mass" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mass</a> <a href="https://mindly.social/tags/satellite" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#satellite</a> <a href="https://mindly.social/tags/deorbit" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#deorbit</a> <a href="https://mindly.social/tags/RunTheNumbers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RunTheNumbers</a> <a href="https://mindly.social/tags/calculation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#calculation</a>edit: typo

Estelle PlatiniTzahal preferred to use “dumb” bombs to strike the homes of the marked persons. “You don’t want to waste expensive bombs on unimportant people — it’s very expensive for the country and there’s a shortage [of those bombs],” said C., one of the intelligence officers.If a junior target lived in a building with only a few floors, the army was authorized to kill him and everyone in the building with a dumb bomb. “We usually carried out the attacks with dumb bombs, and that meant literally destroying the whole house on top of its occupants. But even if an attack is averted, you don’t care — you immediately move on to the next target. Because of the system, the targets never end. You have another 36,000 waiting.”<a href="https://www.972mag.com/lavender-ai-israeli-army-gaza/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.972mag.com/lavender-ai-israeli-army-gaza/</a><a href="https://techhub.social/tags/calculation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#calculation</a> <a href="https://techhub.social/tags/productivity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#productivity</a> <a href="https://techhub.social/tags/yield" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#yield</a> <a href="https://techhub.social/tags/duty" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#duty</a> <a href="https://techhub.social/tags/protocol" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#protocol</a> <a href="https://techhub.social/tags/ethics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ethics</a> <a href="https://techhub.social/tags/efficiency" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#efficiency</a> <a href="https://techhub.social/tags/industry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#industry</a> <a href="https://techhub.social/tags/DefundIsrael" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DefundIsrael</a> <a href="https://techhub.social/tags/casualties" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#casualties</a> <a href="https://techhub.social/tags/Unit8200" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Unit8200</a> <a href="https://techhub.social/tags/patriotism" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#patriotism</a> <a href="https://techhub.social/tags/JewishSupremacy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#JewishSupremacy</a> <a href="https://techhub.social/tags/MilInt" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MilInt</a> <a href="https://techhub.social/tags/military" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#military</a> <a href="https://techhub.social/tags/army" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#army</a> <a href="https://techhub.social/tags/IDI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IDI</a> <a href="https://techhub.social/tags/IDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IDF</a> <a href="https://techhub.social/tags/Unit8200" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Unit8200</a> <a href="https://techhub.social/tags/Lavender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lavender</a> <a href="https://techhub.social/tags/Gaza" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Gaza</a> <a href="https://techhub.social/tags/Hamas" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Hamas</a> <a href="https://techhub.social/tags/warCrimes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#warCrimes</a> <a href="https://techhub.social/tags/israel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#israel</a> <a href="https://techhub.social/tags/family" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#family</a> <a href="https://techhub.social/tags/home" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#home</a> <a href="https://techhub.social/tags/parenting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#parenting</a>
