Throw a DART at a rock in the sky Test the tech that we need to survive Don't let Earth get hit by meteors Don't go extinct like the dinosaurs The strategy for planetary defense Tells us to test out what might make sense To save planet Earth from hazards in space Benefits all of the human race The Double Asteroid Redirect' Test Tries the technique we think might work best To stop the impact of PHOs Not to be used against Earthly foes Didymos has a small orbiting moon Gonna get hit by a copper slug soon DART's gonna smack it and alter its speed Much information from this test we'll heed Ground telescopes will observe the event And measure the delta-V change implement Its sister ship, AIM was meant to be flown But ESA bailed, so we went in alone Deflection? Disruption? We're not really sure Depends on the asteroid's interior Would it miss Earth entirely? Or split up and rain down as space debris? DARTs mission will give us much confidence On how best to come to Earth's defense Let's give a shout out to heroes we know Hail Lindley Johnson and the PDCO!
