NASA to soon crash DART into an asteroid. Here’s how to see it.
NASA is preparing for an “Armageddon”-like mission of crashing a spacecraft into an asteroid, and it wants the public to watch live.
Asteroids frequently get close to striking Earth, but it has been more than 65 million years since a catastrophic collision with our planet. There has been renewed interest in objects hurtling toward us since the popularity of the 2021 doomsday comedy “Don’t Look Up.”
NASA will test its plan in case the scenario ever actually plays out.
The space agency’s Double Asteroid Redirection Test, or DART, will crash into the asteroid Dimorphos, which orbits a larger asteroid named Didymos, next month. Scientists say neither asteroid is headed toward Earth, but Dimorphos, an estimated 520 feet long, is an asteroid that could cause significant damage if it were to hit Earth, NASA says.
Regardless of the outcome, the mission will give astronomers and scientists important data on what the response would be if an asteroid is on a collision course with Earth. No threat exists now, scientists say.
“We don’t want to be in a situation where an asteroid is headed toward Earth and then have to be testing this kind of capability. We want to know about both how the spacecraft works and what the reaction will be … before we ever get in a situation like that,” Lindley Johnson, planetary defense officer for NASA, said in November.

When will DART hit the asteroid Dimorphos?
DART will complete its 10-month journey through space on Sept. 26 at 7:14 p.m. ET. NASA’s live coverage will begin at 6 p.m. ET.
Ten days earlier, DART will release a tiny observation spacecraft that will capture the collision.
Where can I watch the DART mission impact?
NASA will livestream the event on NASA TV and on its website. It also can be viewed on its accounts on Facebook, Twitter and YouTube.

What will DART do?
The collision will happen about 6.8 million miles from Earth. Coming in at 15,000 mph, DART won’t destroy Dimorphos but will “give it a small nudge.” The collision will change the asteroid’s orbit by about 1%, which would be enough to divert one from Earth.
“It’s such an exciting mission,” Andy Cheng, lead investigator of DART, said in November. “It’s unbelievable.”
