Bennu collides with the Earth? Asteroid unlocks human secrets

Bennu, the most dangerous asteroid outside space, may solve the mystery of where does man come from?…

Interest in the space industry occurs again when the capsule is removed from the spaceship Osiris Rex Who travels off-world to collect rock samples (sample return mission) from “Asteroid Bennu” Since 2016, Bennu has returned to Earth and landed safely. Desert area in Utah on September 24, 2023 around 10pm Thailand time. Before officials transported the capsule by helicopter. To prepare for further study of the origins of life in the solar system.

October 20, 2020 Spaceship Osiris Rex Able to land on Bennu’s surface and begin the sample collection mission Touch and Go (TAG) Two days later, the team received images confirming the vehicle. Collect enough samples to meet your needs. Weight is about 2 ounces or 60 grams.

Information from the site NASA Determine it “Pino” It likely broke away from a much larger carbonaceous asteroid about 700 million to 2 billion years ago. Which is likely to take shape asteroid belt Title Between Mars and Jupiter It began to approach the Earth, and scientists assume that it is an organic molecule Pino It may be related to the molecule that started life on Earth.

In addition to the possibility of solving the puzzle of living organisms Pino It is also an asteroid considered by NASA “It is the most dangerous space rock in the solar system.” These are interesting things “Pino” Create your own online Thiirath news team Must pick up the phone to call “Dr. Mathivun Tangmatitham” Astronomer National Institute for Astronomical Research (public organization)

At the time of discussing this information, the doctor had gone to work in Greece while on a mission to accompany the competition delegation. Astronomy and Astrophysics International Academic Olympiad Junior School Level (IOAA Jr.) in Volos, so we got to know outer space across continents…

Why are astronomers interested in these asteroids? Because they happened at about the same time as everything else in the solar system. Traveling back in time to see the origins is something that can’t be done yet. But studying asteroids would be like going back to studying the origins of the solar system. Asteroids are objects that maintained the state of the solar system 5 billion years ago. without change

Despite the fact that in that mysterious abyss there will be many asteroids that the space industry is interested in, Dr. Mattivon said that the reason Pino It is the primary goal of education because there are factors that facilitate the task. Collecting rocks for exploration on Earth or what is called a sample return mission, so the things that must be taken into consideration when sending a spacecraft on a mission are: The easiest, closest and takes the least amount of time. Uses the least amount of fuel.

Most asteroids will have a composition similar to that of a meteorite. That fell into the world, but before it became a meteorite, it causes some elements to burn. So we can’t study bringing rocks from the planets to study so it will be more clear.

As Dr. said Pino The other asteroids were born together with the solar system, so its composition is the same as Earth’s. Imagine if Benbo and the other asteroids merged together. It may become a planet similar to our Earth.

“He believed that perhaps the asteroid belt between Mars and Jupiter once harbored a planet. But he was disturbed by Jupiter’s gravity, turning them into small masses. Instead of gathering together into one large mass. Therefore, studying their elements is like studying the elements of the world.” Dr. Mattivon said.

Something else makes Pino Interesting because It is a rather dangerous asteroid. Because they are arranged in order to be one of the asteroids orbiting near Earth.

Most of these asteroids revolve around the sun. But it has its own orbit that will not come close to Earth at all. As for our world, it has gravity. Which may cause the orbit to change, but it is difficult to calculate the amount of change. Scientists then performed orbital simulations. Sometimes this is found If it approached a small gap in space, Bennu’s orbit would oscillate, perhaps enough for it to come back and collide with the world.

Bennu’s diameter is about 500 meters, and if it collides with the Earth, the energy generated is greater than the energy of the largest nuclear bomb in the world. As far as humanity has ever been created, which is considered very severe, the most dangerous year supposed to occur is around the year 2135.

“It was very close. But to say it was close is still farther than the distance between the Earth and the Moon. The one that was approaching and moving away repeated this cycle. But if it really collided with the world, the potential energy numbers As much as I searched for information. This is equivalent to about 1,200 megatons of TNT. By comparison, the largest nuclear bomb, the Tsar Bomba, had a power of 54 megatons, indicating that the energy density would be twenty times greater.“

The doctor said we suspected it Pino Is there water now we found it? “There was water.” It may contain parts of organic materials, and this is sufficient to create life on Earth. Now we have a sample, if we analyze it in detail. You may get more answers.

Dr. Mattivon’s statement is consistent with the article. “Asteroid Bennu may have been home to ancient water flows.” Or “asteroid Bennu.” It may be the source of ancient currents.

From the article, this appears in the study Pino For the first time, scientists used high-resolution images from OSIRIS-REx as well as spectroscopy. [(Spectroscopy) ซึ่งเกี่ยวข้องกับการวิเคราะห์ คลื่นแม่เหล็กไฟฟ้าที่ปล่อยออกมาจากเบนนู เพื่อตรวจสอบคุณสมบัติของมัน] To study and understand the formation of Nightingale Crater on this asteroid.

The study found that the rocks in this area are similar to those found in chondrite carbonate meteorites that fell to Earth. This indicates that this rock interacted with water one day.

Hannah H. Kaplan, a planetary scientist from NASA’s Goddard Space Flight Center in Maryland. Bennu stated: “This path indicates water flowing through the asteroid. From the beginning in the history of the solar system.”

The doctor said it would be very difficult for us to travel to an asteroid. Because if we compare it to traveling on Earth, we only think about moving from one point to another. But in space, besides thinking about getting to a certain point you also need to make things just as quickly.

“Suppose a missile hits an asteroid very quickly. But in space, you cannot brake. If you want to stop a missile, you must change the speed of the missile to match the speed of the asteroid. When they become equal, go in and collect a sample. When the mission is completed, you must change its speed to be different from the speed of the asteroid. The asteroid and increasing its return distance to Earth would have to change its speed to become similar to the Earth’s speed to be able to release the collected samples to fall through the Earth’s atmosphere, so obtaining this sample is very difficult. But it can be done this way. I think it is “It was really cold.”

Another interesting thing about Pino That is, when the spacecraft will be lowered to collect samples. You must move slowly Dr. compares it “Insect walking speed” Initially it was expected that if you can touch the ground it will release gas to disturb. Hopefully, the remains of Bennu’s skin will enter the sample store

But the actual position of the spacecraft touching Bennu’s surface is all over the place. As if the earth was about to explode. Bennu’s surface is more hollow than previously thought. “These stars are like pebbles. They are held loose by gravity. When they spread out, gravity will gradually pull them back together again.”

The doctor said that these studies there is something to worry about. “Life on Earth would live on an asteroid.” Therefore, when it reaches the world something may be contaminated. Therefore, these tasks require a high degree of caution. The sample must be kept sealed. The study room is specially equipped. To prevent pollution from the world

After the capsule arrives at the temporary operating base NASA In Utah, which is not far from the recovery site. Officials took the capsule and stored it in a special clean room. To prepare to move forward NASA’s Johnson Space Center (NASA’s Johnson Space Center), which will be responsible for opening and maintaining the capsule.

“For this mission the pieces will be divided between different countries. To investigate jointly, such as sending to NASA, Canada and JAXA (Japan Aerospace Exploration Agency) because each laboratory has different expertise. And helping each other to verify like that creates credibility for the results that will come out. This is A standard that has already been implemented.”

finally Pino Will the mysteries hypothesized by scientists be solved, or will humanity discover new secrets? From this study This is something that needs more follow-up.
