🟡 Military Infrastructure Damage | 6/10 🇺🇸 🇮🇷 🇰🇼 Destruction of US helicopter shelters in Kuwait Satellite imagery confirms that Iranian strikes in the final days of the war completely destroyed two helicopter shelters at Camp Buehring, a US Army base in Kuwait. 💬 SENTINEL: Значне пошкодження інфраструктури США, що може вплинути на оперативні можливості в регіоні. #US #Iran #Kuwait #Military #Satellite

They. Vent. The Urine. Into. Space. Think about that for a moment. I could entertain myself thinking about it all day. It gives new meaning to the term "Golden Showers." #ArtemisII #Space #Toilet #SpaceDebris #Satellite https://defector.com/artemis-boldly-goes-where-no-toilet-has-gone-before

Over the past few years, the number of #satellite launches has skyrocketed. There are now nearly 15 000 active #satellites in orbit around the Earth, most of them part of mega-constellations in which each satellite has a service life of only a few years. New satellites must be quickly launched as replacements. To avoid leaving old, dead satellites in Earth’s already-crowded low orbits, most satellite operators deliberately de-orbit them into Earth’s upper atmosphere. That approach is now being taken to a vastly larger scale and there are implications for Earth’s #climate and #atmosphere. Rocket launches already contribute to climate change and #ozone depletion. Scaling them up to deploy a million aircraft-sized satellites would push upper-atmosphere heating and ozone loss far beyond previous estimates, with the steady burn-up of dead satellites compounding the impacts. This is just a fraction of what is to come if planned mega-constellations go ahead. Operators worldwide have already asked for a combined total of over one million satellites. The very smallest particles, finer than a human hair, can stay suspended in the atmosphere for years, contributing to ozone depletion and climate change. A million satellites could mean that a teragram of alumina accumulates in the upper atmosphere – enough, alongside launch emissions, to significantly alter atmospheric chemistry and heating in dramatic ways we do not yet understand. There is no public mandate for a single company in one country to make changes on that scale to the planet’s atmosphere. #space #astronomy https://theconversation.com/a-new-space-race-could-turn-our-atmosphere-into-a-crematorium-for-satellites-276366
