It is revealed that the sample of asteroid 'Benne' recovered by NASA's spacecraft contained abundant carbon and water essential for living things

NASA's planetary probe '

OSIRIS-REx ' collected surface samples from the asteroid Bennu and dropped the samples to Earth on September 24, 2023. As a result of investigating the samples collected by NASA, it has been reported that organic substances including carbon and water molecules were confirmed in the samples.

OSIRIS-REx was launched on September 8, 2016, and arrived at the asteroid Bennu on December 3, 2018. After exploring Bennu from 2019 to 2020, surface samples were collected on October 20, 2020. After that, it began its return to Earth on May 10, 2021.

The capsule containing Bennu's surface samples collected by OSIRIS-REx landed at the Utah Test and Training Range at 10:52 a.m. local time on September 24, 2023, and was recovered by NASA.

The recovered capsule was then transported to the Johnson Space Center in Houston, Texas, which has a clean room dedicated to space sample analysis, where the capsule was opened and the samples analyzed. The amount of sample recovered during this mission was approximately 250g, the largest amount ever returned from an asteroid.

The sample was analyzed jointly by NASA, the University of Arizona, and others, using electron microscopes and infrared measurements.

The results of the survey will be published on October 11, 2023, and the images released at that time show small black rocks, pebbles, and dust inside the capsule. According to Dante Lauretta of the University of Arizona, in addition to water molecules trapped in carbon and minerals that are essential for life on Earth, compounds such as iron sulfide and iron oxide were also confirmed.

Many space scientists believe that the reason why Earth's oceans, rivers, and lakes exist is that they were formed by a collision with a watery asteroid about 4.5 to 4 billion years ago. It is also believed that carbon, which is necessary for the birth of life such as proteins, enzymes, and DNA, was also transported by asteroids, and NASA has confirmed that water and carbon, etc., were discovered in the samples from asteroid Bennu. It is hoped that this will be useful for research into the origin of life on Earth and the formation of the solar system and its planets.

Furthermore, it is estimated that the asteroid Bennu, which orbits the sun at a distance of approximately 81 million km from the Earth, will come closest to the Earth in 2182 and may collide with the Earth, with a low probability of approximately 1 in 2700. The data provided by OSIRIS-REx will also be useful in research to avoid future asteroid collisions.
