#asteroiddeflection — Public Fediverse posts

A solution to mitigate low #deflection efficiency is to apply multiple low-energy impactors rather than a single high-energy impactor 💥. A lower kinetic energy impactor results in a smaller crater 🕳️ that is less affected by global curvature, increasing momentum transfer efficiency https://www.nature.com/articles/s41467-025-56010-w

Any useful deflection of a larger #asteroid ☄️ would require a far greater shove or need to occur decades ahead of an impending collision 💥 to have a cumulative effect. You’d need 1,000 #DARTs to get the same deflection https://www.astronomy.com/science/how-we-track-near-earth-asteroids/

SLIMの復帰! 今週の宇宙飛行
https://www.youtube.com/watch?v=QjhFrEPRtto

NASAのDARTミッション後の小惑星の変化や超大質量ブラックホールの新たな知見、世界中の打ち上げ活動の総括など、興奮の連続だった宇宙飛行の今週を振り返る。日本のSLIM月面着陸機の頑強さ、

ULAの象徴的なDelta IV Heavyの最終飛行、フランスの小型衛星打ち上げ機への投資なども。次週に控える興奮の打ち上げに備えよう。 #SpaceExploration #NASA #DARTMission #BlackHoles #SpaceLaunches #LunarLander

#LLNL Unveils Advanced Simulations for #Nuclear #AsteroidDeflection Strategies
This new tool improves our understanding of the #nuclear deflection’s radiation interactions on the asteroid’s surface while opening the door to new research on the shockwave dynamics affecting the inner asteroid.
