Scientists have achieved even better results than expected. Now they know how to protect the Earth from dangerous space rocks.

Exactly two weeks of research and observation of the asteroid Didymus and its satellite, the asteroid Dimorph, showed that the DART mission was 100% successful. The spacecraft was able to change the course of the target asteroid and the results of the mission even exceeded the expectations of scientists, writes ScienceAlert.

On October 11, NASA officially announced that the collision of the DART with the asteroid Dimorph (its size is approximately 160 m) led to a change in its rotation period around the asteroid Didymus (its size is approximately 800 m) by as much as 32 minutes.

If before that Dimorph made a complete revolution around its “master” in 11 hours and 55 minutes, now its orbital period is 11 hours and 23 minutes. Previously, scientists assumed that the orbit of this space rock, which is larger than the Egyptian pyramid of Cheops, will be changed by 22 minutes. But this result exceeded all expectations.

NASA CEO Bill Nelson said that in the event of a future danger posed by an asteroid flying towards Earth , humanity has protection. After all, the test showed that the impact of a spacecraft on an asteroid can change the trajectory of its flight.

Focusalready wrote that on September 27, the DART apparatus approached its target and struck an asteroid at a speed of 22.54 thousand km/h. It is worth noting that the asteroid itself was moving at a speed of about 21 thousand km/h and at the time of the collision was at a distance of 11 million km from the Earth.

Didyme and Dimorph were not chosen by chance to test the technology to protect the Earth from asteroids. They revolve around the sun every 2 years and do not pose a threat to our planet. But, the best way to measure the change in the flight path of a space rock after an impact is when it has a very short orbit. In this case, Dimorph seemed to be an ideal candidate for scientists in this regard.

As Focus already wrote, the first ever “space accident” of this kind was monitored by telescopes on Earth and observatories in space, who made amazing images of the moment the spacecraft and the asteroid collided.

As a result of the impact, thousands of debris broke off from the asteroid Dimorph, which flew into space and this temporary “tail” made the space rock look like a comet. Focus has already written that scientists have calculated and found that this flow of debris has a length of 10,000 km. Two weeks of observations with telescopes located in Chile, South Africa and the United States allowed NASA scientists to announce the success of the DART mission with 100% certainty.

An important result of this cosmic catastrophe was that scientists were able to confirm the theory that the asteroid Dimorph is still not a solid stone, but is a “pile of rubble.” That is, individual small stones are held together by mutual gravity.

According to scientist Tom Statler from NASA, the asteroid's orbit was changed so much, among other things, due to the huge ejection of debris that flew away after the impact. This ejection also gave momentum to the space rock, which changed its movement.

Focus has already written that the best way to represent the size of the Dimorph asteroid is by comparing it with the size of a person. This was done using photographs of the asteroid sent by DART.

According to scientists, if an asteroid like Dimorph fell to Earth, it would definitely destroy a huge city and its surroundings. But so far, scientists do not expect such falls (and impacts of larger asteroids) in the next 100 years. But the intervention of the gravitational influence of other space objects on any asteroid flying towards our planet can change everything. Therefore, NASA decided to test the operability of the asteroid deflection technology.
