NASA's Osiris-Rex probe successfully returns samples from the asteroid Bennu, revealing the origin of life on Earth and the formation of the solar system
of Hayabusa ', dropped samples collected from the asteroid Bennu to Earth on September 24, 2023, and collected the samples. The capsule was successfully recovered. This resulted in a sample return , a first for the United States.

TOUCHDOWN! NASA Just Returned to Earth With The Largest Asteroid Samples Ever : ScienceAlert
NASA's official X account posted on September 24th, ``Touchdown! 'We landed at the Utah Test and Training Range at 23:52 (23:52),' announcing the sample's arrival on Earth.
TOUCHDOWN! The #OSIRISREx sample capsule landed at the Utah Test and Training Range at 10:52am ET (1452 UTC) after a 3.86-billion mile journey. This marks the US's first sample return mission of its kind and will open a time capsule to the beginnings of our solar system. pic.twitter.com/N8fun14Plt— NASA (@NASA) September 24, 2023
OSIRIS-REx was launched on September 8, 2016, arrived at the asteroid Bennu on December 3, 2018, and after exploring sample collection sites from 2019 to 2020, it was launched on October 20, 2020. Samples were collected. It will then begin its return journey to Earth on May 10, 2021.
The capsule dropped from OSIRIS-REx to Earth was undamaged, and the asteroid samples that tell us what the universe looked like 4.5 billion years ago were also uncontaminated.

The capsule recovered from the Utah desert was taken to a temporary clean room, where it underwent a nitrogen purge , which involves blowing in nitrogen, an inert gas, to preserve the sample.

Samples collected from the asteroid Bennu will help scientists around the world better understand the formation of planets, the origin of the organic matter and water that fueled life on Earth, and the potential future dangers to Earth. It is expected that humanity will benefit from learning about asteroids that may affect humans.
'I congratulate the OSIRIS-REx team on their picture-perfect mission as America's first asteroid sample return, which will provide new insights into the origin and formation of our solar system,' said NASA Administrator Bill Nelson. What's more, Bennu is a potentially dangerous asteroid, so what we can learn from the sample will give us a better understanding of the types of asteroids that could come towards us. It will also be useful.'
The samples will now be sent to the Johnson Space Center in Houston for further research, with initial results expected to be announced at a press conference on October 11th. Most of the samples will be stored for future research, about a quarter will be used immediately for experiments, and a small amount will be sent to mission partners Japan and Canada.
This is the third sample return by OSIRIS-REx in the world, following the Japanese spacecraft Hayabusa and Hayabusa 2. The sample recovered from Bennu is estimated to weigh 250g, which is more abundant than the small sample brought back by Hayabusa in 2010 and the approximately 5.4g sample brought back by Hayabusa2 in 2020. , is attracting attention as it will enable more tests.
'The sample return is truly historic. This will be the largest sample we have brought back since the Apollo moon rocks,' NASA scientist Amy Simon told the media. did.
Bennu, which is about 500 meters in diameter, is made up of materials from the solar system that date back about 4.5 billion years. Samples recovered from Bennu contain water molecules trapped in carbon and minerals, the building blocks of life on Earth. It is believed that this includes.
It is also estimated that Bennu, which orbits the sun at a distance of about 81 million km from Earth, will reach its closest approach to Earth in 2182, and that there is a chance of it colliding with Earth, although the probability is approximately 1 in 2,700. The data provided by OSIRIS-REx will also be useful in research to avoid asteroid collisions.
In 2022, NASA conducted a DART mission that deflected a spacecraft by hitting an asteroid, successfully influencing the movement of Dimorphos , a satellite of a near-Earth asteroid.
