LAUREL, Md. (NASA PR) — 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.(more…)
