Earth simply obtained a particular supply: Items of an historic asteroid that had been snagged straight from the supply and dropped off within the western Utah desert. After touring by area for practically three years, the journey is simply starting for the dear rock samples, which may assist scientists determine the story of life.
On Sunday, NASA’s OSIRIS-REx dropped off a capsule of rocks and dirt collected from asteroid Bennu on the Division of Protection’s Utah Take a look at and Coaching Vary close to Salt Lake Metropolis. The collected items from the asteroid are being prepped to bear intensive evaluation by scientists all over the world, all aiming to higher perceive the origin of organics and water that led to life on Earth. Bennu can also be a near-Earth doubtlessly hazardous asteroid, due to this fact learning it carefully might help us be taught extra about its potential threats to our planet.
Following its parachute-assisted touchdown at 10:52 a.m. ET, a helicopter carried the pattern capsule in a cargo web to a short lived clear room the place it was related to a steady movement of nitrogen. The nitrogen purge, as scientists name it, is supposed to forestall Earthly contaminants from getting into the canister containing items of Bennu in order that the asteroid pattern stays pure for scientific evaluation.
On Monday, the Bennu pattern, an estimated 8.8 ounces of asteroid rock and dirt (250 grams), shall be transported in its unopened canister to NASA’s Johnson Area Middle in Houston by plane. There, scientists will lastly open the canister, extract and weigh the pattern, create a list of what’s inside, and distribute items of Bennu to groups of scientists all over the world, in accordance with NASA.
Bennu is a small, near-Earth asteroid that makes a detailed go to Earth each six years or so. Scientists consider Bennu may need damaged off from a a lot bigger carbon-rich asteroid about 700 million to 2 billion years in the past, and drifted a lot nearer to Earth since then.
“Efficiently delivering samples from Bennu to Earth is a triumph of collaborative ingenuity and a testomony to what we are able to accomplish after we unite with a standard function. However let’s not neglect—whereas this may increasingly really feel like the tip of an unimaginable chapter, it’s really only the start of one other,” Dante Lauretta, principal investigator for OSIRIS-REx on the College of Arizona, Tucson, mentioned in an announcement. “We now have the unprecedented alternative to research these samples and delve deeper into the secrets and techniques of our photo voltaic system.”
The OSIRIS-REx mission launched in September 2016 and reached asteroid Bennu in December 2018. After practically two years of observations, the spacecraft landed on Bennu and snagged a pattern from its floor in October 2020. On Could 10, 2021, OSIRIS-REx mentioned goodbye to Bennu and commenced its journey again house to drop off its treasured cargo.
The spacecraft was 63,000 miles (102,000 kilometers) away from Earth’s floor when it launched its pattern capsule towards Earth’s environment at 6:42 a.m. ET, in accordance with NASA. After dropping off its pattern, the OSIRIS-REx spacecraft started making its method in the direction of its subsequent mission of exploring asteroid Apophis. Accordingly, the mission shall be renamed to OSIRIS-APEX (OSIRIS-Apophis Explorer).
The pattern capsule made its method down at speeds of 27,650 miles per hour (44,500 kilometer per hour), and it pierced the environment at 10:42 a.m. ET off the coast of California at an altitude of about 83 miles (133 kilometers). Round 10 minutes later, the capsule landed within the Utah desert with the assistance of two parachutes to sluggish it down.
“The entire staff had butterflies at this time, however that’s the centered anticipation of a important occasion by a well-prepared staff,” Wealthy Burns, venture supervisor for OSIRIS-REx at NASA’s Goddard Area Flight Middle, mentioned in an announcement. “For us, this was the World Sequence, ninth inning, bases-loaded second, and this staff knocked it out of the park.”

This marks the primary time that NASA has returned floor samples from an asteroid. Japan achieved the identical feat in December 2020, returning samples of asteroid Ryugu as a part of the Hayabusa2 mission.
