This is pretty cool.

Nearly two decades ago, a near-Earth asteroid was discovered to have a moon and the binary system was given the name “Didymos”—Greek for “twin,” a loose description of the larger main body and the smaller orbiting moon, which became unofficially known as Didymos B.

In 2022, that moon will be the target of NASA’s Double Asteroid Redirection Test (DART), the first full-scale demonstration of an asteroid deflection technology for planetary defense. The DART spacecraft will execute a kinetic impact, deliberately crashing into the asteroid to change its motion in space. To mark this historic mission, Didymos B is getting an official name of its own: Dimorphos.

The DART spacecraft launch window begins November 24, 2021. DART will launch aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base, California. After separation from the launch vehicle and over a year of cruise it will intercept Didymos’ moonlet in late September 2022, when the Didymos system is within 11 million kilometers of Earth, enabling observations by ground-based telescopes and planetary radar to measure the change in momentum imparted to the moonlet.

Maybe THAT's why they're sending James T. Kirk up to space on Wednesday!

If they are sending Bruce Willis along, I’m all for it.

Was it like that arcade game Missile Command?

Always loved the actual physics involved....(*) There's nothing wrong with an experiment. But don't expect any Bruckheimer class fireworks.

(*) like a flea biting an elephant. The orbital disruption is microscopic.

Will be a drag when they bump it just enough to now make it crash into the earth.

Considering how much radioactive waste we have, why not launch a massive low yield dirty nuke at it? I'm only partially kidding.
