Spitballing about DART & Dimorphos. Yes, actual scientists have done TONS of rocket science, impact calcs, modeling, scenarios, etc, & now are analyzing data for making this efficient & viable at redirecting killer asteroids. But this is just for funsies! A 🧵 This was basically a fast refrigerator hitting a stadium sized gravel pile. In my head, that's not what an asteroid was. They're MOUNTAINS. IN. SPACE. But as a lot of recent missions have shown, and asteroid researchers suspected for years, a lot are just loose piles of rubble.
