‘Planet Killer’ Asteroid Spotted That Poses Distant Risk to Earth
Several [asteroids] no doubt sneak about near Mercury and Venus. But it’s “incredibly difficult to discover objects interior to Earth’s orbit with our current discovery telescopes,” Dr. Thomas said. During most hours of the day, the sun blinds Earth’s telescopes and objects can be hunted only in the few minutes around twilight.
On Monday [Sept. 26]at 4:13 p.m. (Arizona time), more than 7 million miles away, NASA’s DART mission, Double Asteroid Redirection Test, successfully slammed into the asteroid Dimorphos, making history as the first step toward a possible future planetary defense strategy (NAU Review, Sept. 28).

For asteroid scientists, their work is just beginning.
By design, the crash occurred when the asteroids were fairly close to Earth.
That allowed telescopes on Earth to get a good look. About 40 of them were pointed at… Read more

Cristina Thomas, assistant professor in the Department of Astronomy and Planetary Science and team lead on the DART mission, along with Jason Wilder, vice president for research, were at Mission control in Laurel, Maryland to witness… Read more
“It’s going to be thrilling—and very stressful—but ultimately, I think we’re going to learn a lot,” says Cristina Thomas, a planetary scientist at Northern Arizona University who leads the observation team for the DART mission.
