Projectile material (red) has been almost completely vaporized leaving very little projectile material in the crater. The maximum depth of excavation is 6–7 km, shown by the originally ...

You probably know that the greatest projectile distance happens with a launch angle of 45 degrees (warning—this is only true on flat surfaces). But maybe you didn't know that there are two ...

Though the days are fast ticking by, that success is far from assured. DART is the first-ever test of what NASA calls a ...

Have you ever sat down and thought “I wonder if a trebuchet could launch a projectile at supersonic speeds?” Neither have we. That’s what separates [David Eade] from the rest of us.
