this is a computer simulation of dart, the double asteroid redirection test, which could be our first line of defence if one of those lumps of rock comes heading our way. nature has given us a setup where we have an asteroid, a binary asteroid, that s approaching close to earth so that we can observe from earth based observatories, but this is a test. and this is how the test will work. astronomers have long been aware of a pair of asteroids called didymos and dimorphous. sometime later next year, dart will target then, smash into them, trying to alter their course. these asteroids are no danger to us, but others might well be. if there was an asteroid that was a threat to the earth, what you d want to do, this technique with would, be many years in advance, decades in advance, such that you would just give this asteroid a small nudge
