Deflecting a Killer Asteroid Is More Complicated Than NASA Thought

In 2022, NASA made a spacecraft in an asteroid to see that the mother can change the orbital period around the asteroid. He called the double asteroid redirection test (dart) aiming to determine which mankind could protect itself from the impact of catastrophic asteroid.

Dart collided with Dimorphos, a small monthly asteroid called Didymos on September 26, 2022. The consequences of the impact were reduced to NASA’s expectations and shortened the orbital period of Dimorphos for 32 minutes. Such a change would be a dangerous asteroid, a dangerous asteroid, which shows that this strategy-kinetic technique can save us in the necessary cases. However, the new study complicates this success story. In case of application of planaryetaria protection, the investigation into the garbage dart, which laid behind this equipment, is not exactly as scientists.

“We have succeeded in the intercept of an asteroid by moving it from orbit,” a research astronomer, a research astronomer at the University of Maryland statement. “Our research shows that although the direct impact of the dart space ship causes this change, gave a large hit of the gangs. Farnham and colleagues have published their findings Magazine of Planetary Science On July 4th.

Dimorphos is an empty conglomeration of a material such as “demolition pile” asteroids, rocks, gravel and stones. This work only applies to this type Asteroi. Darts collided with a solid body, a solid body, the impact would not produce these strange effects. Again, there are many demolition pile asteroids in the galaxy, so it is important to understand how to respond to kinetic techniques.

Researchers analyzed the pictures taken by an Italian Space Agency satellite, Lysaaacube, installed on the dart space ship. About two weeks ago, Ligiaile separated I have started the satellite in about three minutes behind the spacecraft, which allows the shelves of collision and its impact and its effects to place its effects again. Crater darts hit the surface of Dimorphos, Lismaacube Ejecta spent the garbage cloud, where he was removed from the asteroid.

These images allowed Farnham and colleagues to watch 104 stones varies between 1.3 to 23.6 feet (0.4 and 7.2 meters). Rocks thrown at a speed of 116 miles per hour (187 kilometers per hour). Strangely, the distribution of this thrown garbage was not accidental, but not against the expectations of researchers.

“We saw that the stones were not scattered in casual space,” he said. “Instead, he said that two bats were in the workplace here with the absence of something that he was not in one place elsewhere.”

One of the two groups with 70% of the garbage hit the south asteroid in high speed and shallow angles. Researchers think that these facilities came from a source in Dimorphos-Dimorphos, the solar panels of darts come from two large stones called Dimorphos and Bodhran, which breaks them before the main trunk of the spacecraft.

When the team compares this consequence according to the deep impact of NASA (epoxy) mission stamped A comet for learning the internal structure, the distribution of debris gave me more. The deep impact hit a rocky surface, filled with large stones, while hitting a surface of very small, single particles. These Ejecta samples resulted in chaotic and filamentary structures, “said the University of Maryend, a professor of astronomy and geology, which has a professor of astronomy and geology, which has a professor of a professor, which has a professor, a professor, which has a professor.

“These two missions compare side by side, this idea of ​​how to respond to the effects of the sky objects that are very important to ensure the success of a planetary defense mission,” he said.

104 Dashed Stone, 1.4% of the energy of the dart space and 96% of this energy was directed to the south representing the “evaluation of important contributions not provided in measurements in the orbital era.” The trash force from Dimorphos, which is far from Dimorphos, can cause the orbital aircraft to a degree from Dimorphos, potentially trapped in space.

“So, understand how the speed of speed in all directions and in any direction is playing the role of fully accounting and surface stones, reducing or developing the impact features,” researchers write “.

There are astronomers cataloged About 2,500 potentially dangerous asteroids in the corner of the galaxy. These are large enough to be surprisingly, and to cause serious damage to the effect. During the next century, the development of such a disaster can prove to improve strategies to prevent such a disaster, in the absence of one of these asteroids, which hit our planet. The success of the dart mission shows that NASA is on the right way, but it shows that we still learn about the impact of a kinetic technique of this new job.
