Humanity hit this asteroid! NASA shows how hard numbers are.

A potentially hazardous asteroid could threaten planet Earth at any time. To avoid any dangerous situation and to divert any near-Earth asteroid, NASA launched the Double Asteroid Redirection Test (DART) spacecraft on September 26, 2022, deliberately named Asteroid Dimorphos. was hit by an asteroid resulting in a successful conversion. its speed. DART’s main purpose was to test NASA’s ability to change the direction of an asteroid. Asteroid Dimorphos orbits another asteroid called Didymos. The Johns Hopkins University Applied Physics Laboratory says the separation between the centers of the two asteroids is 1.18 kilometers (0.73 mi).

Data from this mission will help inform researchers. How Remove the path of a potentially dangerous asteroid. Earth, if ever necessary. The DART experiment also provided fresh insights into planetary collisions that may have been common in early times. solar system.

So, if you’re wondering what happened after the collision, know that scientists have just revealed the same.

According to one Reports by the The nature“The impact caused the asteroid’s orbit around another space rock to shrink – Dimorphos now completes an orbit 33 minutes faster than before the impact.”

“Now, five studies in Nature describe the final moments of the crash and how it affected the asteroid. One group combined data on the spacecraft’s trajectory with images of the asteroid’s surface,” the report added. impacted with. At a speed of more than 6 km/s, the first part to hit was one of its solar panels, which smashed into a 6.5-meter-wide cliff. The US$330-million dart disintegrated.”

Incredibly, at least one million kilograms of rock from Dimorphos’ 4.3 billion kilograms was ejected by the impact. NASA’s Hubble Space Telescope also captured a series of images of the asteroid Dimorphos when it was deliberately struck by a 1,200-pound NASA spacecraft.

A Hubble time-lapse movie of the Dart’s aftermath shows hour-by-hour changes as bits of dust and debris are thrown into space. “Smashing into the asteroid at 13,000 mph, the Dart impactor blasted more than 1,000 tons of dust and rock from the asteroid,” NASA has said in one of its reports..

The movie shows three overlapping stages after the impact: the formation of an ejecta cone, the spiraling of debris around its companion asteroid along the asteroid’s orbit, and the tail being swept behind the asteroid by the pressure of sunlight (wind as in sock. stuck in the air).
