KOMPAS.com- For the first time, scientists were surprised to find water and organic matter in asteroid. This discovery provides a new understanding of how the Earth formed.
Scientists found organic materials in samples from asteroid Itokawa in the first Hayabusa mission carried out by the Aerospace Exploration Agency Japan ( JAXA) In 2010.
Reporting from The Independent, Thursday (11/3/2021), a sample of a rock from the asteroid was analyzed, and for the first time the material contained in this asteroid material surprised scientists.
In the sample there was water and organic matter that did not come from an alien world, but from the asteroid itself.

Scientists from Royal Holloway, University of London, English, states that asteroids have evolved over billions of years to include liquid and organic matter in the same way as Earth.
Asteroid it goes through extreme heat, dehydrates and breaks, but manages to reshape and re-hydrate using the material it extracted.
The study suggests that the S-type asteroid, which is the most common to come to Earth, could contain a crude component of life.

The results of this analysis could rewrite our knowledge of the history of life on Earth, which previously focused on carbon-rich C-type asteroids.
“The Hayabusa mission is a robotic spacecraft developed by JAXA to return samples from a small, near-Earth asteroid called Itokawa, for detailed analysis in the Earth laboratory,” said Dr Queenie Chan of the Department of Earth Sciences at Royal Holloway.
Dr Chan added that after being studied in detail by an international team of scientists, an analysis of a sample of an asteroid, dubbed the Amazon, had preserved primitive organic matter. The material is not processed by heating it within a 10 micron distance.

According to the researchers, the heated organic material indicates the asteroid has heated to more than 600 degrees Celsius in the past.
The presence of unheated organic material is very close to it, meaning that primitive organic matter arrived at Itokawa’s surface after the asteroid cooled.
Research scientists entitled Organic Matter and Water from Asteroid Itokawa this has been published in the journal Scientific Reports.
“This finding is very interesting because it reveals the complex details of the asteroid’s history and how its evolutionary path is very similar to that of a prebiotic Earth,” said Dr Chan.
It is hoped that this sample analysis can become the basis for a more detailed analysis of other samples.

JAXA’s Hayabusa2 mission returns the pieces asteroid Ryugu last year, brought back a piece of space rock that is only 38 cm in diameter.
In 2019, a sample from asteroid Bennu revealed that the asteroid was actually older than scientists had previously thought.
Asteroid Bennu has provided a new view of how evolution is Solar system we are developing.
In addition, observations on the asteroid Bennu also confirm the presence of widespread and abundant hydrated material, as well as the presence of surprisingly large boulders.
