Why Is A NASA Spacecraft Crashing Into An Asteroid?
LOADING ERROR LOADING CAPE CANAVERAL, Fla. — In the first-of-its kind, save-the-world experiment, NASA is about to clobber a small, harmless asteroid millions of miles away. “This is stuff of science-fiction books and really corny episodes of “StarTrek” from when I was a kid, and now it’s real,” NASA program scientist Tom Statler said Thursday. “This really is about asteroid deflection, not disruption,” said Nancy Chabot, a planetary scientist and mission team leader at Johns Hopkins University’s Applied Physics Laboratory, which is managing the effort. Asteroid Strike-Explainer via Associated Press DART, THE IMPACTOR The Johns Hopkins lab took a minimalist approach in developing Dart — short for Double Asteroid Redirection Test — given that it’s essentially a battering ram and faces sure destruction. Another spacecraft, Near-Earth Asteroid Scout, is loaded into NASA’s new moon rocket awaiting liftoff; it will use a solar sail to fly past a space rock that’s less than 60 feet next year.
