Index – Tech-Science – They looked at who could protect an asteroid

NASA has tested what would happen if an asteroid crossed the Earth’s path. The result is not very encouraging, as we will not be able to prevent catastrophe and the orb will wreak havoc on the planet.

This continues for a week simulation On the first day of April 19, participants were told that an asteroid called 021PDC is currently located 35 million miles from Earth and has a chance to cross our planet’s orbit on October 5, nearly half a year from now.

According to the simulations, the imaginary second day happened much later, on May 2. By this time, the participants have already been told that the asteroid is likely to collide with North Africa or Europe. Since then, the idea of ​​how to prevent a disaster using available technological tools began.

Scientists have gained more and more information about the asteroid day by day. For example, they learned that a celestial body was likely to collide with Earth near the German-Czech-Austrian triple boundary, and that the consequences of the collision would be similar to the detonation of a larger nuclear bomb.

The researchers looked at each option. They also studied, for example, whether they could launch a spacecraft that could still hijack or destroy a celestial body in space.

However, despite their attempts, they failed to prevent fictional catastrophe.

Although the researchers came up with ideas, they failed to come up with any solution that would prevent the celestial body from colliding within six months. The asteroid finally collides in Eastern Europe and wreaks havoc.

Had we encountered this scenario in real life, we would not have been able to build and launch a spacecraft capable of destroying the asteroid in such a short time.

In addition to launching the spacecraft, it was also suggested that if To the orb If a nuclear missile were launched that would collide even outside the atmosphere, they would be able to prevent the catastrophe. Here, they concluded that while this could reduce the rate of destruction, its prevention would likely be minimal – especially if it was a larger asteroid.

The simulation was certainly useful as it demonstrated that we are not yet ready for this crisis.

So far, as far as we know, there is no asteroid that could endanger our planet. However, all of this is overshadowed by the fact that NASA estimates that a large percentage of asteroids in space – about two-thirds – are not seen in time because they are so small.

There have been examples in recent years that space explorers have lost some of the celestial bodies passing dangerously close to Earth. For example, the 3-mile-diameter Newwise traversed 64 million miles from us last July, and scientists noticed an astronomical body just four months before it approached our planet.

Closer in 2019 was a 427-foot-diameter asteroid that flew just 45,000 miles from Earth, and NASA noticed it until shortly before. And in 2013, a 65-foot-diameter asteroid exploded over the Russian city of Chelyabinsk. The orb fell to pieces even in the air, but it still caused a shock wave that destroyed many buildings and injured 1,400 people.

The problem is also complicated by the fact that it takes some luck to detect asteroids: one of our high-performance space telescopes must look in the right direction in time to detect the movement of celestial bodies. That is why space agencies are constantly working to develop more and more space telescopes to mitigate the threat.

Experts are also studying several defense options. One of them is that a large explosive charge is detonated in space, which in turn is deflected from the asteroid so that it does not collide. Another possibility is the development of laser projectiles, which are then fired at, diverted, or destroyed the asteroid.

And the third option is to create a large spacecraft of noble simplicity, aimed directly at the asteroid. Simply put, NASA is taking it very seriously. As part of the DART program, with the participation of the European Space Agency, I would like to test the technology on an asteroid called Dimorphos in the near future, as the spacecraft they launched will be able to fully transform in the fall of 2022. This asteroid does not pose a threat to Earth in any way, but it may be appropriate. Test the idea on it.

In light of all this, we can probably be confident that we will not reach the fate of the dinosaurs whose destruction 65 million years ago could have been caused by an asteroid six miles in diameter.
