Asteroids threaten global devastation – NASA warns | Contact Us | News


Asteroid experts at NASA and John Hopkins University plan to redirect Earth-bound asteroids before they collide with the planet. The surprising revelation comes after NASA astronomers have agreed that the threat of a harmful asteroid reaching Earth is too high to ignore. The daring plan will involve the fall of a space probe directly into an asteroid in an attempt to drastically change its trajectory. Even the smallest of the orbital changes can result in the lack of space on Earth's rock for millions of miles.

The plan, called the Double Asteroid Redirection Test (DART), will cause NASA to join a pair of binary asteroids in October 2022.

If successful, the asteroid collision test will set the stage for future Earth defense initiatives.

Hundreds of tons of cosmic debris hit Earth's atmosphere every day, but most of it is dust and sand that burns before reaching the ground.

The real threat comes from the tens of thousands of small asteroids that zodify around the Earth and the Sun.

Paul Chodas, NASA's leading asteroid expert, warned that smaller asteroids are the most unpredictable.

He told the Washington Post: "Even with one kilometer Size, if hit in the right place, could cause global devastation. It's the little asteroids that represent the risk. "

Astronomers received a rude awakening in 2013 when a 20-meter-wide space rock passed the undetected Earth radars and exploded over Russia.

The so-called Chelyabinsk Meteor detonated over the Chelyabinsk Oblast in Russia with 30 times the strength of the Hiroshima nuclear bomb.

More than a thousand people were injured by broken glass from the resulting air jet and more than 7,000 buildings were damaged.

But the asteroid may seem absolutely inconsequential when compared to the much larger asteroids that hide in the depths of space.

Last weekend, an estimated 1,115.5 feet wide (340m) asteroid skimmed the Earth at a distance of almost 6.72 million kilometers.

And another 360-foot-wide rock is ready to pass our planet tomorrow.

To combat this threat in the cradle, NASA's DART initiative promises to spare mankind from the fate of dinosaurs.

Elena Adams, DART's chief engineer, said: "It's like a big missile. It's very exciting. You are really doing something for the fate of humanity. "

The European Space Agency (ESA) estimates that about 90% of dinosaur-sized asteroids have been discovered and are being counted.

But according to all estimates, these gigantic space rocks are not as populous as the smaller rocks, such as the Chelyabinsk Meteor.

ESA said: "The main challenge comes from the population of medium-sized objects, ranging from tens to hundreds of meters in diameter.

"There are many of these asteroids and most have not yet been seen.

"Any impact from one of them can actually cause damage to a town or populated area.

"But if they are discovered early enough, their point of impact can be estimated with a fair degree of accuracy and measures can be taken to protect people."

The space agency stressed that no object deserves any concern at the moment, but many asteroids are not detected, so the quest for deep space threats must continue.
