On November 24, the NASA DART will launch a mission to smack an asteroid into a new orbit to prepare for the possibility that an asteroid in the future might threaten Earth: "But don't worry, experts agree that there is no possibility that (even if it goes awry) this asteroid-smashing could threaten Earth," said NASA official.
Astronomer Amy Mainzer, who is the principal investigator of NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission and who specializes in characterizing populations of asteroids and comets, said that right now, we are aware of only about 30-40% of the large objects, or objects about 459 feet (140 meters) and larger, near our planet. "That's great, but it means we still have more work to do."
