Late final yr, a spacecraft containing samples of a 4.6-billion-year-old asteroid landed safely within the desert after a 1.2-billion mile journey. There was just one little downside: NASA couldn’t get the canister containing its prized rocks open.
After months of tinkering, scientists at NASA’s Johnson House Middle in Houston lastly dislodged two caught fasteners that had saved the items of the asteroid Bennu out of researchers’ palms.
“It’s open! It’s open!” NASA’s Planetary Science Division posted Friday on X, together with {a photograph} of the slate-colored bounty of mud and small rocks contained in the canister.
Scientists needed to change course on the canister opening effort in mid-October after it grew to become clear that not one of the gadgets in NASA’s field of accepted instruments may drive open the final two of 35 fasteners sealing the canister.
To forestall the pattern from being contaminated by Earthly air, it has been saved in a clear room within the Houston facility the place hazmat-suited curators delicately dismantled the canister. The group custom-designed new instruments to pry open the ultimate latches.
The company will now end extracting the roughly 9-ounce pattern, which might be weighed and chemically analyzed. A lot of the payload from OSIRIS-REx (an acronym for Origins, Spectral Interpretation, Useful resource Identification, and Safety-Regolith Explorer) will then be frozen and punctiliously preserved in order that future generations of scientists will be capable of examine it with superior applied sciences.
“We’re overjoyed with the success,” NASA’s chief OSIRIS-REx pattern curator, Nicole Lunning, mentioned in an announcement.
It took greater than seven years and roughly $1 billion to convey again a pattern from Bennu, an area rock shaped through the earliest days of the photo voltaic system. The asteroid samples discovered on Earth have primarily been cooked by their searing journey by means of the ambiance, which limits what scientists can study from them.
With OSIRIS-REx, “the target is to convey again an historical piece of the early photo voltaic system that’s pristine,” NASA astrobiologist Jason Dworkin instructed The Occasions in September. “You should use these leftovers of the formation of the photo voltaic system to assemble what occurred in that formation.”
The spacecraft that collected the pattern in 2020 and launched it towards Earth in September is now heading on to its subsequent mission. The craft, now named OSIRIS-APophis EXplorer, or OSIRIS-APEX, is on its solution to a peanut-shaped asteroid named Apophis.
For a brief (however alarming) time, astronomers thought Apophis is likely to be on monitor to smash disastrously into Earth. Now that that worrying chance has been dominated out, scientists are eagerly looking forward to 2029, when the asteroid will go nearer to Earth than any object of its dimension ever has.
“It’s one thing that just about by no means occurs, and but we get to witness it in our lifetime,” JPL navigation engineer Davide Farnocchia mentioned final yr. “We often ship spacecraft on the market to go to asteroids and discover out about them. On this case, it’s nature doing the flyby for us.”
