Mysterious Material Obtained From Asteroid Bennu Leaving Scientists Puzzled
In a significant development, NASA's OSIRIS-REx mission has discovered an unusual and unidentified material in samples from the potentially hazardous asteroid Bennu. The finding comes alongside evidence of organic molecules, offering new insights into the origins of life on Earth.

samples from the 3-billion-year-old asteroid that were collected in late 2020 and described as dark, carbon-rich, and organic molecule-laden resemble "hummocky boulders" with a unique, rough texture. The specimen were obtained in late 2020 and only touched down on Earth about two months back.
Interestingly, Dante Lauretta, the mission's principal investigator, noted during a conference held by the American Geophysical Union that these particles have a tendency to cling to any surface they touch.
"We definitely have hydrated, organic-rich remnants from the early solar system, which is exactly what we were hoping when we first conceived this mission almost 20 years ago," Lauretta said.
The OSIRIS-Rex spacecraft, designed for a brief six-second contact with Bennu, unexpectedly plunged deeper and longer into the asteroid's surface.
This led to an over-collection of material, resulting in some of it escaping from the sample collector's head into the outer lid, due to a stone jamming open a small flap.
