NASA scientists have lastly disassembled the canister containing rocks snatched from a distant “probably hazardous” asteroid, and now you possibly can look inside.
The pattern — roughly 8.8 ounces (250 grams) of rocky area rubble that the OSIRIS-REx spacecraft collected from the asteroid Bennu — is assumed to comprise a number of the earliest precursors to life and is the primary chunk of an area rock ever grabbed by a NASA mission.
After touchdown within the Utah desert on Sept. 24, the OSIRIS-REx capsule was taken to NASA’s  Johnson House Heart in Houston, the place scientists started engaged on its disassembly. But two out of the capsule’s 35 fasteners bought caught, that means that NASA engineers needed to design and manufacture two bespoke clamp-like instruments from scratch. Produced from surgical metal, the instruments had been used to take away the clasps and crack open the capsule on Jan. 11.

OSIRIS-REx mission scientists spent almost two years looking for a touchdown website on Bennu’s craggy floor earlier than the spacecraft touched down to gather the pattern. Upon making contact with the asteroid, OSIRIS-REx fired a burst of nitrogen from its Contact-and-Go Pattern-Acquisition Mechanism to stay the touchdown and stop the craft from sinking by means of the asteroid, in addition to to seize the pattern.
The capsule’s long-awaited contents embody roughly 4.5 billion-year-old rocks from the earliest years of the photo voltaic system. Additionally they comprise a number of the primordial parts believed to have sparked life on Earth.
A few of these constructing blocks — together with uracil, one of many nucleobases for RNA — had been not too long ago discovered on the asteroid Ryugu by the Japan Aerospace Exploration Company’s Hayabusa2 spacecraft, which returned to Earth with its rock pattern in 2020. OSIRIS-REx mission scientists are hoping to seek out different such organic precursors contained in the Bennu pattern.
