[1] https://en.wikipedia.org/wiki/Atira_asteroid the three new ones, discovered and announced a day or three back: https://www.smithsonianmag.com/smart-news/three-near-earth-asteroids-were-h= iding-in-the-suns-glare-180981055/ (Atira class are rocks within earth orbit. They are very hard to see, probably overly baked (low on volatiles), and get bright sun all the time) [1] I'm very inspired by DART, but afraid to do the math for this tonnage and speed. (anyone? there's a LOT of zeroes... ) I have project ploughshare on my mind, except kinetic, and it's less deflection on my mind than reducing a rubble pile to rubble, identifying the good pieces, and bringing them back. --=20 This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-69813666656= 07352320-FXtz Dave T=C3=A4ht CEO, TekLibre, LLC
