NASA's OSIRIS-REx mission has made history by becoming the first mission to return samples from a near-Earth asteroid (NEA). This morning, the sample
Key Highlights :
NASA's Director Bill Nelson expressed his congratulations to the OSIRIS-REx team for their efforts. He said, “You did it. You designed it, you built it, and you carried out a first mission to collect a sample from an asteroid. And after a two-year journey, it has touched down at the Utah Desert. It brought something extraordinary: the largest asteroid sample ever received on Earth. It’s going to help scientists investigate planet formation. It’s going to improve our understanding of asteroids that could possibly impact the Earth, and it will deepen our understanding of the origin of our Solar System and its formation. This mission proves that NASA does big things. Things that inspire us, things that unite us, things that show that nothing is beyond reach.”
The OSIRIS-REx mission began in 2018, when the spacecraft rendezvoused with the carbonaceous asteroid Bennu. After two years of studying the asteroid from orbit, OSIRIS-REx began descending toward its surface on October 20th, 2020. After collecting between 400 grams and 1 kg (0.88 to 2.2 lbs), the spacecraft departed on May 10th, 2021, and began returning to Earth. The sample return capsule deployed its parachutes and touched down on the surface at the UTTR ten minutes later.
The sample return capsule was then loaded onto a cart and taken into a temporary clean room to remove the unopened sample canister. All the parts will packaged for transport by aircraft and flown to NASA’s Johnson Space Center. Once the samples have been delivered to the Johnson Space Center, they will be analyzed for clues about the formation and evolution of the Solar System.
The OSIRIS-REx mission has since continued onto the next leg of its mission, which will be to study Apophis. This NEA was previously thought to pose a potential risk to Earth – aka. a Potentially-Hazardous Asteroid (PHA) – though scientists have since indicated there’s a slight risk it might impact Earth in 2068. This mission extension was announced on April 25th, 2022, and NASA indicated it would henceforth be known as the OSIRIS-APEX (‘APophis EXplorer’) mission. The mission will rendezvous with Apophis in April 2029, when the asteroid makes an extremely close pass to Earth, then orbit the asteroid for about 18 months before retrieving a sample.
The successful return of the OSIRIS-REx samples marks a major milestone in space exploration. It is a testament to the hard work and dedication of the team at NASA, and it has provided us with a glimpse into the formation and evolution of the Solar System. The samples from Bennu and Apophis will be invaluable to scientists in understanding the Solar System, and the OSIRIS-REx mission will continue to be a source of inspiration and discovery for many years to come.
