LOS ANGELES – NASA launched a spacecraft Tuesday nighttime connected a ngo to smash into an asteroid and trial whether it would beryllium imaginable to sound a speeding abstraction stone disconnected people if 1 were to endanger Earth.

The DART spacecraft, abbreviated for Double Asteroid Redirection Test, lifted disconnected from Vandenberg Space Force Base atop a SpaceX Falcon 9 rocket successful a $330 cardinal task with echoes of the Bruce Willis movie “Armageddon.”

If each goes well, successful September 2022 it volition slam head-on into Dimorphos, an asteroid 525 feet (160 meters) across, astatine 15,000 mph (24,139 kph).

“This isn’t going to destruct the asteroid. It’s conscionable going to springiness it a tiny nudge,” said ngo authoritative Nancy Chabot of Johns Hopkins Applied Physics Laboratory, which is managing the project.

Dimorphos orbits a overmuch larger asteroid called Didymos. The brace are nary information to Earth but connection scientists a mode to measurement the effectiveness of the collision.

Dimorphos completes 1 orbit of Didymos each 11 hours, 55 minutes. DART’s extremity is simply a clang that volition dilatory Dimorphos down and origin it to autumn person toward the bigger asteroid, shaving 10 minutes disconnected its orbit.

The alteration successful the orbital play volition beryllium measured by telescopes connected Earth. The minimum alteration for the ngo to beryllium considered a occurrence is 73 seconds.

The DART method could beryllium utile for altering the people of an asteroid years oregon decades earlier it bears down connected Earth with the imaginable for catastrophe.

A tiny nudge “would adhd up to a large alteration successful its aboriginal position, and past the asteroid and the Earth wouldn’t beryllium connected a collision course,” Chabot said.

Scientists perpetually hunt for asteroids and crippled their courses to find whether they could deed the planet.

“Although determination isn’t a presently known asteroid that’s connected an interaction people with the Earth, we bash cognize that determination is simply a ample colonisation of near-Earth asteroids retired there,” said Lindley Johnson, planetary defence serviceman astatine NASA. “The cardinal to planetary defence is uncovering them good earlier they are an interaction threat.”

DART volition instrumentality 10 months to scope the asteroid pair. The collision volition hap astir 6.8 cardinal miles (11 cardinal kilometers) from Earth.

Ten days beforehand, DART volition merchandise a tiny reflection spacecraft supplied by the Italian abstraction bureau that volition travel it.

DART volition watercourse video until it is destroyed connected impact. Three minutes later, the trailing trade volition marque images of the interaction tract and worldly that is ejected.
