NASA will launch the world's most massive

OSIRIS-REx's destination is the asteroid Bennu, with the goal of seeking the origin of life as well as the origin of the Solar System.

In September, NASA will launch into a "vacuum cleaner" , a spacecraft called OSIRIS-REx . Don't assume this is a cosmic dust cleaner and dump it into some black hole dump for clean space, this is a machine, used to vacuum the universe to bring about research.

The mission of OSIRI-REx is to bring samples to scientists worldwide to look for the origin of life , water and even the origin of the planets. The results of these studies can help us better understand, or find new discoveries about our own planet Earth.

Small clumps of matter formed from dust clouds from the solar system's birth. They gradually grow bigger and some of them become planets like now, and when those planets collide, they have more material to support them. Scientists believe that it is the celestial celestial bodies that bring the life component to Earth.

What they were looking for would be amino acids , a brick to build a protein chain, and other signs from the asteroid Bennu, a celestial body that circled the Sun and was quite close to the Earth. This is not an idle decision, it is obvious that scientists have not spent 12 years researching to do so, they have previously found amino acids in some meteorites falling on Earth.

The mission of OSIRI-REx is to bring samples to scientists worldwide for research.

According to scientist Jason Dworkin, who works at NASA and is a member of the OSIRIS-REx project, to understand the origin of this Solar System, scientists need ancient specimens, and they have chosen asteroids. Tinh Bennu made the destination for this ship.

After 12 years of research, this week was the last week they checked this ship before they put OSIRIS-REx's in the air."It's hard not to shed tears on our 12-year achievement, but I don't want the ship to be contaminated before taking off," Mr. Dworkin joked.

This week was the last week they checked the ship before they put OSIRIS-REx's in the air.

"We have conducted a full supply of fuel for it and now OSIRIS-REx is ready to travel," said Rich Kuhns, OSIRIS-REx program director at NASA. In the coming days, the research and construction team will take the ship to the installation station and be ready for the upcoming trip.

The Atlas 5 missile will start on September 8, to launch OSIRIS-REx on its 7-year journey. This mission must be successfully launched by October 12, otherwise everything will be delayed until another year.

OSIRIS-REx will return to Earth in September 2017 to get help from the home's gravity, throwing force to launch the asteroid Bennu - a 500-meter-diameter celestial body believed to contain A lot of carbon, the backbone of organic molecules.

In August 2018, OSIRIS-REx will reach Bennu and gradually move into its orbit. The ground steering committee will conduct a review, follow-up and find a response point for sampling.

"We want to identify an area with the potential to concentrate many organic and mineral components, in order to be able to answer questions that have caused many scientists a long headache, or at least to answer. as much as possible".

OSIRIS-REx has certain limitations. It can only handle stones with a diameter of about 2cm, so scientists have to try to find places that have a large amount of soil that can be easily collected."We don't need a big stone to do anything, just a little bit of soil to determine the signs of organic."

This mission must be successfully launched by October 12, otherwise everything will be delayed until another year.

The landing of the Bennu asteroid will also be carried out slowly and firmly. With the gravitational force here equal to 10 micro-g, one-thousandth of the Earth's gravitational force, the landing is almost the same as connecting the spacecraft to the space station.

The OSIRIS-REx system will suck up the material with a nitrogen engine and keep them in the cargo compartment, with depths of up to 20cm below Bennu's surface. Just 60 grams of rock will be enough for researchers to study, although in the experiment, the ship's "vacuuming" system can achieve a capacity of several hundred grams. If the scientists are not satisfied with the first suction result, then OSIRIS-REx is also equipped with two nitrogen tubes to make additional sampling attempts possible.

Once the "pick up" task of OSIRIS-REx has been completed, it will shift to other goals, including measuring the path of Bennu's future . Its ratio of falling to Earth at the end of the 22nd century is 1/2700, the ratio is still proportional and scientists are trying to calculate how bad the situation might be.

According to the director of Kuhns, keeping the spacecraft clean is one of the greatest challenges of this entire space program. According to him, many types of glues or lubricants are not used with OSIRIS-REx as with other normal space missions."Because the goal is to bring back the soil from Bennu safely, so the process of keeping our bacteria-free environment extremely tight."

To ensure cleanliness, the OSIRIS-REx suction system is separated and installed only in the final test phase, to avoid it being affected by the bacteria on Earth.

After completing its mission, OSIRIS-REx will return, throwing a container of cosmic material into the Earth's atmosphere on a Sunday morning, September 24, 2023. The research team will welcome head of the container in a landing area in Utah, then transfer it to the NASA center in Houston to proceed with the study. With the help of electron microscopes, supercomputers and an electron-accelerator system as big as a large room, objects from the asteroid Bennu will be able to uncover the secret of the origin of life. .

OSIRIS-REx will return, throwing a container of cosmic material on September 24, 2023.

A 12-year study followed by a 7-year space journey, we are hoping for positive results in samples taken from Bennu. In order to find out the origin of life (or humanity), the origin of the planets in this Solar System, we must make efforts to further study and OSIRIS-REx is such a step.
