During a mission to deflect a distant asteroid, NASA celebrated on Tuesday exceeding expectations, and it is a sci-fi training of humanity''s ability to prevent an incoming cosmic object from ravaging lives on Earth.

The fridge-sized Double Asteroid Redirection Test impactor was deliberately smashed into Dimorphos on September 26, putting it into a smaller, faster orbit around Didymos, according to NASA chief Bill Nelson.

It increased the length of time the orbital period by four percent, or 32 minutes from 11 hour 55 minutes to 11 hours 23 minutes, boosting the goal of ten minutes.

"At some point in the future, if we find an asteroid that is threatened to hit Earth, and would be large enough to really do some damage, thank goodness that we will have had this successful test," Nelson said.

Every 2.1 years, the asteroid pair loop together around our Sun, posing no threat to our planet.

They are nevertheless ideal for evaluating the "kinetic impact" technique of planet defense.

DART''s success as a proof-of-concept has made a reality what was once science fiction notably "Armageddon," "Deep Impact," and "Don''t Look Up."

Dimorphos, which is 530 feet (160 meters) in diameter or roughly the size of a massive Egyptian pyramid, was never imagined before as a shadow of light around an hour before impact.

In the last few moments, its egg-like shape and craggy, boulder-dotted surface finally came into clear view, as DART sprinted towards it at roughly 14,500 kilometers per hour.


In the days following, astronomers marveled at the vast majority of matter collected by Earth and space telescopes, as well as a tiny companion satellite that departed the area with DART.

Dimorphos has evolved into a man-made comet grace to its seemingly new tail.

A basic telescope telescope investigation required a few weeks to establish how the test performed.

The binomial asteroid system, which was roughly 6.8 million miles (11 million kilometres) from Earth at its collision, is only visible as a single dot from the ground.

The brightness of the dot has changed as Dimorphos passes in front of Didymos, which is substantially greater at half-a-mile wide.

Observer said that four optical telescopes were involved in the orbital period in Chile and South Africa, while two US radar telescopes aided in the discovery.

The asteroid is less like a solid rock, rather than a "rubbish pile" of boulders bound by mutual gravity, according to the researchers.

If an asteroid is stronger, the spaceship''s momentum will be limited. But if significant mass is pushed at high velocity in the opposite direction to impact, there will be a further boost.

"It appears like the recoil from the ejecta blast off the surface was a substantial contribution to the overall push given to the asteroid," said NASA scientist Tom Statler at a briefing.

According to a fellow tester, the experiment will serve as a "anchor step" for simulations and calculations regarding the outcome of future impacts.

Mass extinction

According to NASA, no known asteroid with a depth of 140 meters (460 feet) in capacity to devastate a city has a significant chance to hit Earth for the next 100 years.

It''s time to wait long enough to see what happens.

According to the geological record, a six-mile wide asteroid struck Earth 66 million years ago, plunging the world into a long winter that resulted in the massive extinction of the dinosaurs along with 75 percent of all species.

The agency intends to begin in 2026 a telescope called the Near-Earth Object (NEO) Surveyor, which can better identify potentially hazardous 140-meter asteroids and comets that travel within 30 million miles.

So far, less than half of the estimated 25,000 NEOs of 140 meters have been discovered.

Kinetic impact with a spaceship is only one way to protect the planet, albeit the only method currently available.

If an approaching object is early, a spaceship might be sent to continue flying alongside it for long enough to divert its path through the ship''s gravitational pull, thus creating a so-called gravity tractor.

Nuclear explosives would be used to redeplace or destroy an asteroid.

The best way to deploy such weapons would be at a distance, without blowing the asteroid to smithers, which would further undermine Earth.
