NASA’s OSIRIS-REx Mission Discovers Pristine Asteroid Pattern Wealthy in Carbon and Natural Compounds

NASA’s OSIRIS-REx mission picked up the pristine 121.6-gram pattern from the near-Earth asteroid in 2020 and returned it to Earth final September.

Since then, scientists have been analyzing the asteroid’s rocks and dirt to see what secrets and techniques they could maintain concerning the asteroid’s composition and whether or not it might have delivered the weather. for all times on Earth. Asteroids additionally shock scientists as a result of they’re the remnants of the formation of the photo voltaic system.

An preliminary evaluation of a part of the pattern, which was shared in October, instructed that the asteroid contained lots of carbon.

Throughout a evaluate of the pattern, the crew discovered that Bennu’s mud is wealthy in carbon, nitrogen and natural compounds, all of which contributed to the formation of the photo voltaic system. These elements are additionally important to life as we perceive it and can assist scientists higher perceive how Earth-like planets evolve.

A examine detailing the findings appeared Wednesday within the journal Meteoritics & Planetary Science.

The primitive sea world

“OSIRIS-REx gave us precisely what we hoped for: a big pristine asteroid pattern, wealthy in nitrogen and carbon, from a beforehand moist world,” mentioned examine co-author Jason Dworkin, OSIRIS-REx challenge scientist at NASA’s Goddard Area Flight Middle in Greenbelt, Maryland, in an announcement.

The most important shock was the invention of magnesium sodium phosphate within the pattern, which was not initially detected by distant sensing when OSIRIS-REx orbited Bennu.

Magnesium sodium phosphate is a water-soluble compound that’s a part of the biochemistry of life.

A microscope picture exhibits a darkish piece of Bennu, a couple of millimeter lengthy, with a crust of vivid phosphate.

“It’s attainable that the asteroid broke away from a small, primitive ocean world that now not exists in our photo voltaic system,” the researchers mentioned.

The rocks collected on Bennu kind a time capsule from the early days of the photo voltaic system, going again greater than 4.5 billion years.
