We now understand precisely just how much product OSIRIS-REx caught from its target asteroid Bennu– and, it’s a lot.
In addition to the 2.48 ounces (70.3 grams) of sample currently gathered from the beyond the cylinder, NASA has actually lastly handled to totally open OSIRIS-REx’s sample container to discover another 1.81 ounces (51.2 grams) of asteroid Bennu within. In all, the probe gathered more than two times what researchers had actually expected.
OSIRIS-REx finished its asteroid sample return objective when the probe parachuted a tightly-sealed container back to Earth on Sep. 24 before starting a secondary objective called OSIRIS-APEX, called for its next area rock target, the asteroid Apophis
With this container came the very first pieces of an asteroid NASA has actually ever recorded and returned for additional research study. The objective introduced in 2016, and the safe healing of the pill in 2015 was the ceremonious end to an impressive seven-year journey through areaWhen NASA specialists got a hold of the sample container, they stumbled upon some issues– it was too tough to open

OSIRIS-REx’s initial objective was to gather approximately 2.12 ounces (60 grams) of product, which was in fact consulted with even simply little bits of Bennu found throughout the container’s outside. The group understood there had to be much more within.
In order to access the whole of the Bennu sample, NASA groups began developing a brand-new tool to open the sealed container.
To talk specifics, the container was in fact protected inside a bigger enclosure, constructed for security throughout the probe’s difficult journey. As OSIRIS-REx gathered its asteroid samples in area, a part of the product ended up inside this protective enclosure however outside the designated sample container, gifting researchers a few of the Bennu sample before the primary container was opened.
Far surpassing their expectations, objective operators handled to gather 2.48 ounces (70.3 grams) before ever opening the unattainable part of the OSIRIS-REx return pill. Still, researchers and area lovers all over stayed waiting to see what OSIRIS-REx’s grand sample overall would be. And now, the brand-new tool having actually been obtained, researchers have gain access to to all of the probe’s asteroid sample, and the outcomes remain in.
Integrated with the samples currently gathered, OSIRIS-REx returned an overall of 4.29 ounces (121.6 grams) of product from asteroid Bennu– that’s more than double the objective’s objective and the biggest asteroid sample ever gathered, according to a current NASA releaseFor contrast, the Japanese Aerospace Agency’s Hayabusa2 objective just restored about 0.18 ounces (5 grams) of product from its asteroid target, Ryugu, in Dec. 2020.
Evaluation of the samples has actually currently started, and researchers are discovering”an entire world of productformerly unattainable utilizing samples gathered from meteoritesaccording to Dante Lauretta, primary private investigator for OSIRIS-REx. Bennu is thought to be a residue of the early planetary systemand researchers believe studying these samples might assist decipher some secrets of early planetary advancement.
About a quarter of the Bennu sample will stay with scientists on the OSIRIS-REx research study group. NASA likewise prepares to maintain a minimum of 70 percent of the sample for research study by researchers worldwide, in addition to for future generations of scientists.
