Boley and Michael Byers, says the rapid development of\nmega-constellations risks multiple tragedies of the commons. That could\ninclude tragedies to ground-based astronomy, Earth orbit, and Earth’s upper\natmosphere. The study asserts that international cooperation is urgently\nneeded, along with a regulatory system that takes into account the effects\nof tens of thousands of satellites.\n\n“[T]he connections between the Earth and space environments are\ninadequately taken into account by the adoption of a consumer electronic\nmodel applied to space assets,” the authors said. “For example, we point\nout that satellite re-entries from the Starlink mega-constellation alone\ncould deposit more aluminum into Earth’s upper atmosphere than what is done\nthrough meteoroids; they could thus become the dominant source of\nhigh-altitude alumina.”\n\nThe authors say their study shows that untracked debris will lead to\npotentially dangerous on-orbit collisions on a regular basis due to the\nlarge number of satellites within mega-constellation orbital shells. The\ntotal cross-section of satellites in these constellations also greatly\nincreases the risk of impacts due to meteoroids. De facto orbit occupation\nby single actors, inadequate regulatory frameworks, and the possibility of\nfree-riding exacerbate these risks.\n\nAccording to Boley and Byers, in 2 years, the number of active and defunct\nsatellites in low-Earth orbit (LEO) has increased by over 50%. “SpaceX\nalone is on track to add 11,000 more as it builds its Starlink\nmega-constellation and has already filed for permission for another 30,000\nsatellites with the [FCC].”\n\nMore than 12,000 trackable debris pieces are already in low-Earth orbit,\ntypically 10 centimeters in diameter or larger, the study asserts.\nIncluding sizes down to 1 centimeter would raise the debris count to about\na million inferred debris pieces that could threaten satellites,\nspacecraft, and astronauts due to their orbits crisscrossing at high\nrelative speeds.\n\nSimulations of the long-term evolution of debris suggest that LEO is\nalready in the protracted initial stages of a mushrooming collision\nscenario, but that this could be managed through active debris removal. The\naddition of satellite mega-constellations and the general proliferation of\nlow-cost satellites in LEO stresses the environment further, the study\nposits.\n\n[ANS thanks ARRL for the above information]\n\n---------------------------------------------------------------------\n\nSuccessful QO-100 Ham Radio Emergency Communications Exercise\n\nOn February 26, 22 stations representing 14 countries in IARU Region 1 took\npart in a short notice exercise using the geostationary satellite QO-100\namateur radio transponder\n\nIARU Region 1 Emergency Communications Co-Ordinator Greg Mossop G0DUB has\nposted:\n\nThis was the first of a number of smaller exercises, tests and meetings to\nbe held by IARU Region 1 throughout the year, building on the earlier\nGlobal Simulated Emergency Tests to cover as many aspects of emergency\ncommunications as possible.\n\nThe intention is to bring emergency communicators together more frequently\nto demonstrate how the Amateur Radio Service can work together as a global\ncommunity and develop a common understanding of each others’ capabilities.\n\nThe exercise on QO-100 was felt to be a success with a number of formal\nmessages being passed between stations along with some learning from the\ninevitable challenges of equipment failures, language barriers and\nco-ordination of an exercise whose coverage area covered from South Africa\nto the United Kingdom. Once all the exercise feedback is received, the next\ntest on that system is planned to take place in October this year.\n\nQO-100 brings another asset to the emergency communications toolbox in\nRegion 1 and its presence is much appreciated.\n\nSource IARU Region 1: https://iaru-r1.org/\n\nQO-100 information: https://amsat-uk.org/satellites/geo/eshail-2/\n\n[ANS thanks Southgate ARC for the above information]\n\n---------------------------------------------------------------------\n\nChanges to AMSAT-NA TLE Distribution for March 10\n\nTwo Line Elements or TLEs, often referred to as Keplerian elements or keps\nin the amateur community, are the inputs to the SGP4 standard mathematical\nmodel of spacecraft orbits used by most amateur tracking programs.

(ANS\nthanks AMSAT-ID for the above information)\n\n+ After at least seven years hurtling through space, a 3-ton (2.7 metric\ntons) discarded rocket stage probably smashed into the moon on March 4 at a\nblistering 5,771 mph (9,288 km/h). The discarded rocket stage was projected\nto land at Hertzsprung crater on the moon's far side at 7:25 a.m. EST (1225\nGMT). This is the first time that space junk has accidentally collided with\nthe lunar surface. But because the collision occurred on the moon's far\nside, it could take scientists months to find the crater and confirm the\nimpact. Many experts believe that the junk is the spent upper stage of a\nrocket launched during one of China's first forays to the moon, in 2014.\nBut Chinese officials disagree. (ANS thanks LiveScience for the above\ninformation)\n\n+ The BIRDS-5 satellite, operating APRS on 145.825 MHz, as well as CW and\n4k8 GMSK AX25 telemetry on 435.375 MHz, is scheduled to be deployed from\nthe International Space Station this week. There seems to be some confusion\nas to the exact date and time of deployment, so watch for further\ninformation. (ANS thanks Tetsu Satou, JA0CAW, for the above information)\n\n+ Astronaut Mark Vande Hei, KG5GNP, who holds the ongoing record for\nlongest space flight, is set to end his 355 days in space in just three\nweeks. The plan is for him to land in Kazakhstan with two Russian\ncosmonauts on a Russian spacecraft. But on Feb. 26, Dmitry Rogozin, the\nhead of Russia's Space Agency and a close ally to Russian President\nVladimir Putin, posted a video in Russian that threatened to leave Vande\nHei behind in space and detach Russia's segment of the space station\naltogether. NASA has remained silent on Rogozin's threats.
