NASA has launched a mission to smash a spacecraft into an asteroid — a world’s first to check asteroid-deflecting expertise. The house probe will crash into the asteroid to change its velocity and course.
“Asteroid Dimorphos: we’re coming for you!” the house company tweeted at this time, together with a clip of the blast off.
Asteroid Dimorphos: we’re coming for you!

The SpaceX Falcon 9 rocket carrying the DART (Double Asteroid Redirection Test) experiment lifted off at 10:21 pm Pacific Time from Vandenberg Space Force Base close to California within the US, NASA TV’s livestream confirmed.
The objective is to barely alter the trajectory of Dimorphos, a “moonlet” round 525 toes (160 meters, or two Statues of Liberty) extensive that circles a a lot bigger asteroid known as Didymos (2,500 toes in diameter). The pair orbit the Sun collectively.
Impact is predicted to happen within the fall of 2022, when the binary asteroid system is 6.eight million miles (11 million kilometers) from Earth, nearly the closest level they ever get.
The take a look at is to seek out out if the expertise is sufficient if an precise asteroid impression risk had been detected sooner or later.
DART’s goal asteroid will not be a risk to Earth at current, NASA stated. But the asteroid belongs to a category of our bodies often called Near-Earth Objects (NEOs), which strategy inside 30 million miles.
“What we’re trying to learn is how to deflect a threat,” NASA’s high scientist Thomas Zuburchen advised information company AFP, speaking concerning the $330 million mission, the primary of its variety.
Traveling at about 15,000 mph, the spacecraft, which weighs 1,344 kilos and is 59 toes throughout, is to collide head-on with Dimorphos.
After DART’s kinetic impression with its goal asteroid, an investigation group will measure how a lot the impression modified the asteroid’s movement in house utilizing telescopes on Earth, NASA stated on its web site.
NASA’s Planetary Defense Coordination Office is most fascinated about these bigger than 460 toes in dimension, which have the potential to degree complete cities or areas with many instances the power of common nuclear bombs.
There are 10,000 identified near-Earth asteroids 460 toes in dimension or better, however none has a big likelihood to hit within the subsequent 100 years. One main caveat: scientists suppose there are nonetheless 15,000 extra such objects ready to be found.
The DART spacecraft additionally comprises refined devices for navigation and imaging, together with the Italian Space Agency’s Light Italian CubeSat for Imaging of Asteroids (LICIACube) to look at the crash and its after-effects.
“The CubeSat is going to give us, we hope, the shot, the most spectacular image of DART’s impact and the ejecta plume coming off the asteroid. That will be a truly historic, spectacular image,” stated Tom Statler, DART program scientist.
Scientists estimate 460-foot asteroids strike as soon as each 20,000 years. Asteroids which are six miles or wider — such because the one which struck 66 million years in the past and led to the extinction of most life on Earth, together with the dinosaurs — happen round each 100-200 million years.
