"On an average of every several hundred thousand years or so, asteroids larger than a kilometre could cause global disasters.". If sample collection occurred as planned, the spacecraft's collector head captured the stirred up material. See today's front and back pages, download the newspaper, One of its future approaches could bring it perilously close to Earth sometime in the next century; it has a one in 2,700 chance of impacting our planet.

The asteroid has an orbit that brings it close to Earth, which is why it’s considered to be a near-Earth asteroid. Even if an asteroid were on a collision course with Earth, NASA says it is 70 percent more likely to hit water than land. A spacecraft may tell us why, The team at NASA has been sharing animations. The samples from Bennu could help scientists understand not only more about asteroids that could impact Earth but also about how planets formed and life began. This image shows the moment the spacecraft briefly used its robotic arm to touch the surface of Bennu, crushing porous rocks in the process. While the chances of an asteroid big enough to destroy a city is about 0.1 percent in any given year. Its solar panels folded into a Y-wing configuration above the spacecraft to protect them. The van-sized spacecraft has to touch down its robotic arm in a landing site called Nightingale. Despite this seemingly enormous distance, NASA has described it as a ‘near-Earth object’ (NEO).

"Today's TAG maneuver was historic," said Lori Glaze, Planetary Science Division director at NASA Headquarters in Washington, in a statement.

Everything went perfectly based on the data returned by the spacecraft, according to Dante Lauretta, the mission's principal investigator and a professor at the University of Arizona Lunar and Planetary Laboratory. I look forward to analyzing the data to determine the mass of sample collected.". An artist's concept of what the OSIRIS-REx spacecraft looks like as it orbits asteroid Bennu. Then, the spacecraft backed away to safety. NASA's OSIRIS-REx touched down on asteroid Bennu on October 20. "A piece of primordial rock that has witnessed our solar system's entire history may now be ready to come home for generations of scientific discovery, and we can't wait to see what comes next.". The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- launched in September 2016. Since arriving at Bennu, the spacecraft and its cameras have been collecting and sending back data and images to help the team learn more about the asteroid's composition and map the best potential landing sites to collect samples. Nightingale was ultimately chosen, and the others serve as backup sites. Site Nightingale (top left) is located in Bennu's northern hemisphere.

It is 20.25 feet in length (6.2 meters) with its solar arrays deployed.

Its width is 8 feet (2.43 meters) x 8 feet (2.43 meters). The spacecraft performed the entire sequence of approaching the asteroid and collecting the sample autonomously since live commands from Earth were not possible. Sites Kingfisher (top right) and Osprey (bottom left) are located in Bennu's equatorial region. ET. — NASA Asteroid Watch (@AsteroidWatch) September 23, 2020 Its closest approach to earth will occur around 7:12 a.m. Located more than 200 million miles from Earth, the asteroid is considered to be a “rubble pile,” which is a grouping of rocks held together by gravity rather than a single object, according to CNN. NASA also says there is nothing to fear as the chance of a major asteroid hitting Earth is very, very slim. The agency will be able to confirm if a sample was successfully collected later and images of the event will be available Wednesday on NASA's site. Imagery will be returned by the spacecraft on Wednesday, which will provide more details of the sample collection and how the spacecraft is faring. In this image taken from video released by NASA, regolith is dispersed as the Osiris-Rex spacecraft attempts to take a sample of the surface of asteroid Bennu on Tuesday, Oct. 20, 2020. NASA has … At 120 metres long, it would be far more catastrophic than Chelyabinsk event in 2013, when a 20m meteor exploded over Chelyabinsk, Russia, smashing windows and injuring more than 1,000 people.
