After months of spying and jimmying, NASA researchers have at last opened the cylinder consistingof product scraped from the “potentially harmful” asteroid Bennu, the firm revealed on Thursday (Jan. 11).
The sample — approximately 8.8 ounces (250 grams) of rocky area debris gathered by the OSIRIS-REx spacecraft — is idea to include some of the earliest precursors to life and is the veryfirst portion of a area rock ever got by a NASA objective.
NASA had currently gathered 2.5 ounces (70 g) of the sample from the container’s cover, however 2 stuck fasteners stopped researchers from reaching the product within. After producing brand-new tools to eliminate the persistent clasps, NASA engineers lastly unsealed the container on Wednesday (Jan. 10).

“Our engineers and researchers have worked relentlessly behind the scenes for months to not just procedure the more than 70 grams of product we were able to gainaccessto formerly, however likewise style, establish, and test brand-new tools that permitted us to relocation past this obstacle,” Eileen Stansbery, chief of NASA’s ARES (Astromaterials Research and Exploration Science) department said in a declaration. “The development and commitment of this group hasactually been impressive. We are all delighted to see the staying treasure OSIRIS-REx holds.”
NASA researchers veryfirst recovered the container on Sept. 24 after it sped back to Earth aboard the OSIRIS-REx pill at speeds of up to 27,000 miles per hour (43,000 kilometers per hour). After a seven-year, 4 billion-mile (6.4 billion kilometer) round journey, the pill released its parachute and securely landed in the Utah desert before being transferred to Johnson Space Center in Houston.
The hold-up on recovering the capsule’s valuable freight was triggered by 2 out of its overall of 35 fasteners getting stuck. To avoid contamination NASA had to preapprove any tools utilized to open the narrow container. The service came in the type of 2 clamp-like tools made from surgical steel; these were veryfirst evaluated in a practicesession laboratory to show they might securely getridof the clasps.
Now that the box hasactually been opened, NASA states it will follow a “few extra disassembly actions” before it can photo, extract, weigh and procedure the staying sample. Small pieces scraped from the cover have currently been sentout around the world for analysis, and will quickly be followed by the contents discovered within.
Bennu is a possibly dangerous asteroid that has a 1-in-2,700 possibility of striking Earth in the year 2182 — the greatest chances of any understood area item. But the researchers are more interested in what’s caught inside the area rock: the possible extraterrestrial precursors of life on Earth.
“This is the mostsignificant carbon-rich asteroid sample ever returned to Earth,” NASA Administrator Bill Nelson stated at a news conference upon the sample’s return. “Carbon and water particles are precisely the components we desired to discover. They’re essential components in the development of our own world, and they’re going to assistance us figureout the origins of aspects that might have led to life.”
Earth’s water is older than the world itself and was mostlikely brought here by asteroid and comet effects. But water mostlikely wasn’t the just product asteroids brought to Earth; the structure obstructs of life mostlikely hitched a trip on a area rock, too. Bennu is a B-type asteroid, which suggests it consistsof high quantities of carbon and, possibly, numerous of the prehistoric particles present when life emerged on Earth.
Some of these structure obstructs — consistingof uracil, one of the nucleobases for RNA — were justrecently discovered on the asteroid Ryugu by the Japan Aerospace Exploration Agency’s Hayabusa2 spacecraft, which returned to Earth with its rock sample in2020 OSIRIS-REx objective researchers are hoping to discover other such biological precursors inside the Bennu sample.
OSIRIS-REx objective researchers invested almost 2 years browsing for a landing website on Bennu’s craggy surfacearea before the spacecraft touched down to gather the sample. Upon making contact with the asteroid, OSIRIS-REx fired a burst of nitrogen from its Touch-and-Go Sample-Acquisition Mechanism to both stick the landing and avoid the craft from sinking through the asteroid.
The blast sentout rocks and dust careening around the craft, and some of that rocky particles landed in a cylinder aboard OSIRIS
