NASA will crash a spacecraft into a 525-foot-wide asteroid in September. Here’s how to watch 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
