Nasa to Divert Asteroid Hit with 'Dart'



The US Aerospace Agency’s (NASA) space mission, called the “Asteroid Binary Redirection Test” (DART), aims to hit an asteroid with the spacecraft and change its direction in a measurable way.

The US Aerospace Agency’s (NASA) space mission, called the “Asteroid Binary Redirection Test” (DART), aims to hit an asteroid with the spacecraft and change its direction in a measurable way.

The vehicle, which is planned to be launched into space in July 2021, is planned to crash into one of the twin Didymos asteroids between Earth and Mars.

The idea of ​​an asteroid heading towards Earth is the subject of many science fiction fantasies, but NASA’s solution to this problem is even more interesting than in movies.

Scientists devised a very cinematographic plan to “punch” an asteroid distant from our planet if it approaches dangerously.

The project is known as the “DART Mission” and was developed by John Hopkins University’s Applied Physics Laboratory in conjunction with several NASA scientists.

Breakthrough space technology includes the technique known as the “kinetic impact” technique that can alter the motion of an asteroid in space.

“DART is a planetary defense-focused technology test aimed at preventing the impact of a dangerous asteroid on Earth,” explains the NASA website.

“DART will be the first demonstration of the kinetic impact technique to alter the motion of an asteroid in space.”

IT WILL SHOCK AT 23,000 KM

NASA’s spacecraft was designed to hit and hit an oncoming asteroid at a speed of about 6.6 km per second.

This should force the asteroid to change the speed of its orbit by only one percent, but hopefully enough to push it away from Earth.

The spacecraft’s launch window will open in July 2021. It will be launched by a SpaceX Falcon rocket, but will leave the vehicle and travel through space for a year.

Eventually the asteroid will meet Didymos and his little bear. The two asteroids are not seen as a threat to Earth, but will pass close enough to be chosen as the DART’s target.

The NASA spacecraft will then collide with the little moon at a speed of 23,000 kilometers, and when the Didymos system reaches 11 million km from our planet, we will be able to observe the impact on the ship’s speed and orbit through telescopes and radar.

Scientists think the collision will change the speed of the moon by one percent and the orbital period around the larger asteroid around a few minutes, a value large enough to be observed and measured with telescopes on Earth. “

“So far, we didn’t have much choice as to what we could do if we found something coming,” APL astronomer and DART research team leader Andy Rivkin told Vice News.

“The DART is the first test of how we can deflect something without having to apply for a nuclear package or by sitting in our basements waiting for it and using our fingers.”

The popular science fiction movies Armageddon and Deep Impact depict fictional scientists using nuclear weapons to detonate an asteroid before it reaches Earth.

DART is unlikely to reorient an asteroid anytime soon, NASA recently announced that we don’t need to worry about an impact for at least another 100 years.
