Last week, OSIRIS-REx circulates the bedrock, which consists of the same molecules that are responsible for life on the planet.
Bennu has recently traveled the OSIRIS-REx spacecraft last week that discovered the presence of water in that primitive asteroid consisting of the same molecules that generated life on Earth. NASA.
"Data from Origins Explorer, Spectral Interpretation, Resource Identification, and Regolith Security (Osiris-Rex) was recently analyzed. has revealed the presence of water in clay, which constitutes its scientific objective, the asteroid Bennu, "NASA said in a statement.
This data obtained by the two spectrometers equipped with the probe indicates the hydroxyls, molecules containing oxygen and hydrogen atoms that are attached to each other.
Researchers responsible for the task "suspect" that these hydroxyl compounds are found throughout the planetoid, states. NASA believes that its presence would only be left.
"Because Bennu is too small to get water, the discovery shows that at some point the presence of fluid occurred in a parallel body, probably a much larger asteroid," the US Space Agency said.
3 NASA announced that OSIRIS-REX had accomplished its first phase consisting of the asteroid's orbit and now runs from Bennu as if it were a satellite to find out how the planets move without gravity defined.
Over the next 12 months, he also seeks to find a suitable place to land on the asteroid so that they can collect samples that can be analyzed when the air returns home.
"When broadcast samples arrive on Earth, in 2023 researchers will get a hidden treasure trove of new information on the history and evolution of our solar system," said NASA mission and science chief. Amy Simon, mentioned in the memo.
Researcher of OSIRIS-REx chief infants and Professor Dante Lauretta, Planetary and Lunar Laboratory of the University of Arizona, explained at a press conference that although Bennu is too small for water the observation shows that the original or "father" of Bennu was possibly some liquid, possibly a much larger asteroid.
"We're talking about an asteroid that can reveal important information about the early formation of the solar system or even the beginning of life on Earth," Lauretta said.
The scientist said that the pictures so far have allowed them to see the rocky surface of the asteroid.
Bennu is about 500 meters in diameter and it is about the size of a small mountain.
