NASA spacecraft will intentionally crash into an asteroidal to save Earth

NASA’s Double Asteroid Redirection Test spacecraft (DART), is now within reach of its target. The probe will crash into Dimorphos in 17 days. It is a natural satellite from the asteroid of Didymos.

Don’t panic. NASA will purposely crash a $330million robot spacecraft into an asteroidal object in the coming weeks. This is to test whether it’s possible to divert an asteroid from hurtling towards Earth using this method. This one isn’t. The DART mission, which stands for double asteroid redirection testing, has space experts excited.

As part of an effort to strengthen our planet defense capabilities, the plan to destroy a spacecraft and make it a binary asteroid is also part. DART was launched in November 2021 and will be used to test whether humanity can redirect an asteroid so that it doesn’t collide with Earth. NASA announced this week that DART was finally able see the light reflecting off Didymos.

NASA will launch a spacecraft this month to test a planetary defense method that could save Earth.

For saving our green planet EARTH, NASA will have to take some action including launching a spacecraft to destroy the enemy in space (Asteroid is the enemy).

For saving the Earth for future impacts from outer space which includes asteroid’s attack, Double Asteroid Redirect Test Spacecraft is used by NASA to smash the enemy asteroid as part of the international collaboration’s mission to make safe every person’s life who live on the Earth.

NASA announced Thursday that the asteroid is not a threat to Earth. However, it was the first time the kinetic impact technique has been tested in the world. NASA used a spacecraft to intercept an asteroid and provide planetary defense.

This image confirms that Didymos is visible from DART’s perspective. NASA plans to crash DART into Dimorphos head-on on September 26. Scientists will collect data from the impact on the trajectory of the asteroid by measuring the orbital changes around Didymos.

Let’s not forget that this is an experiment. NASA claims that Didymos or Dimorphos pose no threat to Earth and that the energy transfer through DART’s impact is sufficiently low to not knock them into an Earthbound trajectory.

DART received its first glimpse at Didymos, a double-asteroid system which includes Dimorphos, recently.

A 20 million mile distant image showed that the Didymos system was very faint. Astronomers were able to pinpoint Dimorphos’ precise location by combining a number of images.

Julie Bellerose, NASA’s Jet Propulsion Laboratory’s DART navigation lead, said, “Seeing the DRACO images from Didymos for first time, can we iron out the best settings and fine-tune software,”.

If DART hits Dimorphos as it is planned, it will test Earth defense theory’s kinetic impactor.

Andy Rivkin, Johns Hopkins Applied Physics Laboratory Astronomer, stated that a kinetic-impactor allows you to ram your spacecraft into an asteroid. Then you alter its orbit around Sun by doing so.

DART will not change Didymos’ orbit. It is designed to alter the speed of Dimorphos, the moonlet. Scientists will eventually be able to tell if their plan worked by using ground-based telescopes or data from the spacecraft.

Asteroids travel around the sun at about 20 miles per hour. Rivkin stated that engineers would not want to alter the orbit of an asteroid by using a kinetic impactor technique to do so.

How to watch this historic NASA moment

  1. DART Could Change Knock Steroids 1% Off Course (Which Is Enough)

Last November, DART, the spacecraft, was launched. It is scheduled to hit the asteroid Dimorphous Sept. 27. When it hits its target, the half-ton craft will travel at four miles per second. The collision will alter Dimorphous’ orbit by 1%, which is enough to prevent an asteroid strike hypothetically on Earth.

Scientists will study DART’s orbit, and the collision if it occurs as planned to determine if the spacecraft is capable of preventing a devastating asteroid strike. It’s like the one in Armageddon. Or the one that smashed into the Earth tens to millions of years ago and decimated three-quarters all living animals and plants. Continue reading to view the video.

  1. Experts Say More Steroid Strikes are Coming

According to Alan Fitzsimmons (a Queen’s University Belfast professor of astronomy), “We know that asteroids have struck us in the past.” This week, Fitzsimmons told The Guardian: These impacts are a natural phenomenon and will continue to occur in the future. We want to prevent the worst. This is the goal of DART.

Lindley Johnson, NASA’s planetary defense officer, seconded the statement: “We don’t want to find ourselves in a situation where an asteroids is heading toward Earth and then we have to test this type of capability.”

  1. Target Steroids Have Been Carefully Studyed

Dimorphos measures approximately 525 miles in width and is located 6.6 million miles above the earth. NASA experts selected it for the test because of its specific characteristics. It poses no threat to the earth. Jay Tate, Director of the National Near Earth Objects Information Center (UK), stated that DART’s target was carefully selected. “Dimorphos orbits Didymos, a larger asteroid. Astronomers have carefully observed its path around Didymos to determine the extent of deflection.

  1. What is the likelihood of a Catastrophic Asteroid Streak?

This could be happening for an urgent reason. Is it possible that an asteroid will strike the earth, causing a major catastrophe? Experts say it is unlikely.

We also know that none of the detected asteroids will be coming near our planet in the next few hundred years. Fitzsimmons says that we can relax in our beds and forget about them.

These smaller objects are being mapped with increasing accuracy. However, we must be ready to act if one is heading towards Earth. DART is the first step towards ensuring that we have the technology necessary to combat the threat.

  1. How to Watch It

NASA has announced that it will live stream NASA-TV’s event and its website. You can also view it on NASA’s Facebook, YouTube, and Twitter pages.

Andy Cheng, DART’s lead investigator, stated last November that “it’s such a thrilling mission.” “It’s unbelievable.”
