    Explanation: This is what it looks like to punch an asteroid. Last month, NASA's robotic spacecraft OSIRIS-REx descended toward, thumped into, and then quickly moved away from the small near-Earth asteroid 101955 Bennu. The featured video depicts the Touch-And-Go (TAG) sampling event over a three-hour period. As the movie begins, the automated probe approaches the 500-meter, diamond-shaped, space rock as it rotates noticeably below. About 20 seconds into the video, Nightingale comes into view -- a touchdown area chosen to be relatively flat and devoid of large boulders that could damage the spaceship. At 34 seconds, the shadow of OSIRIS-REx's...

    Two days after touching down on asteroid Bennu, NASA's OSIRIS-REx mission team received on Thursday, Oct. 22, images that confirm the spacecraft has collected more than enough material to meet one of its main mission requirements -- acquiring at least 2 ounces (60 grams) of the asteroid's surface material.

    Make sure to go to the link and click on the hotlink highlighted as "Touch-And-Go (TAG) sampling event" for a video of the touchdown. A photo sequence is also shown in the last hotlink in the Explanation or by clicking on the image at the link. Explanation: On October 20, after a careful approach to the boulder-strewn surface, the OSIRIS-REx spacecraft's arm reached out and touched asteroid Bennu. Dubbed a Touch-And-Go (TAG) sampling event, the 30 centimeter wide sampling head (TAGSAM) appears to crush some of the rocks in this snapshot. The close-up scene was recorded by the spacecraft's SamCam...

    Want a little reminder of how amazingly clever we humans can be? Yesterday, from a distance of more than 320 million kilometres (200 million miles) away, NASA scientists piloted a spacecraft to gently touch down on a spinning asteroid, collecting a sample of surface rubble to bring back home to Earth. At 6:08 PM EDT, the signal from spacecraft OSIRIS-REx reached Earth to let us know that it had successfully touched down at the Nightingale collection site on asteroid Bennu, within a metre (three feet) of its target, and safely bounced back up again after just 6 seconds of contact....

    Imagine parallel parking a 15-passenger van into just two to three parking spaces surrounded by two-story boulders. On October 20, a University of Arizona-led NASA mission 16 years in the making will attempt the astronomical equivalent more than 200 million miles (320 million kilometres) away. A NASA mission called OSIRIS-REx will soon attempt to touch the surface of an asteroid and collect loose rubble. OSIRIS-REx is the United States' first asteroid sample return mission, aiming to collect and carry a pristine, unaltered sample from an asteroid back to Earth for scientific study. The spacecraft will attempt to touch the surface...

    In just a few days, NASA is going to bounce its probe OSIRIS-REx off asteroid Bennu. The mission will collect a sample from the asteroid, and return it to Earth for closer study - one of the first missions of its kind. That return sample will help us to understand not just asteroids, but the earliest days of the Solar System's existence. However, that is not the sole mission of OSIRIS-REx. The probe arrived in Bennu orbit in December of 2018, and since that time has been using its suite of instruments to learn as much as it can about...

    OSIRIS-REx — an international sample-return mission led by NASA and joined by science team members from Canada, France, Germany, the United Kingdom, and Italy, and with an instrument provided through the Canadian Space Agency — is less than one month away from performing a Touch-And-Go sample collection maneuver to return portions of asteroid Bennu to Earth. Meanwhile, science teams have observed regular material shedding activity from the near Earth object — an unexpected find that allows scientists to better understand the dynamic little worlds littered throughout the inner solar system.

    The probe has been orbiting the asteroid since 2018 and has been preparing to collect a chunk of asteroid rock, which it will bring back to Earth in 2023. OSIRIS-REx is set to take the sample from the site named Nightingale on Oct. 20, 2020, but on May 26 the spacecraft took a dive toward Osprey, the backup sample collection site for the mission. OSIRIS-REx dropped down to just 820 feet (250 meters) above the site, which is the closest the spacecraft has been to Osprey. During the operation, the probe took 347 images from PolyCam, one of three cameras...

    Astronomers have discovered more than 20,000 so-called near-Earth asteroids, or space rocks whose orbits pass within about 30 million miles (50 million kilometers) of Earth's orbit. Whereas comets erupt with long tails of gas, dust and debris when they streak near the sun, the vast majority of near-Earth asteroids appear inert. However, previous research found that a small number of asteroids, such as the asteroid 133P/Elst-Pizarro, could actively erupt with large amounts of dust and bits of rock — enough to create temporary clouds or comet-like tails that are visible from Earth-based telescopes. Much remains unknown about what drives such...

    The English tabloid Express ran a story today (Feb. 11) with the headline "NASA warn 'APOCALYPSE asteroid' Bennu WILL appear in the sky this Valentine's Day." The piece claimed that the 1,640-foot-wide (500 meters) asteroid Bennu — "a doomsday asteroid which has a high probability of impacting Earth in one hundred years time" — will be "visible to the naked eye" on the night of Feb. 14, slightly to the right of Mars. This is entirely wrong. First of all, Bennu is not an "apocalypse asteroid," and NASA never labeled it such. (Agency scientists aren't known for their hyperbolic and...

    Bennu has a shape that looks a bit like a spinning top. It is roughly 500 meters (1,640 feet) in diameter and orbits the sun once every 1.2 years, or 436.604 days. Every six years or so, it comes very close to Earth — about 0.002 AU, according to the University of Arizona. (... well within the orbit of Earth's moon.) Bennu is part of a small class of carbonaceous (dark) asteroids that likely have primitive materials in them. Called a B-type class, Bennu and other asteroids like it have materials such as volatiles (compounds with a low boiling point),...

    CAPE CANAVERAL, Fla. (Reuters) - A U.S. space probe was cleared for launch on Thursday to collect and return samples from an asteroid in hopes of learning more about the origins of life on Earth and perhaps elsewhere in the solar system, NASA said on Tuesday. A United Launch Alliance Atlas 5 rocket was scheduled to blast off from Cape Canaveral Air Force Station in Florida to dispatch the robot explorer Osiris-Rex on a seven-year mission. United Launch Alliance is a partnership of Lockheed-Martin and Boeing. Osiris-Rex is headed to a 1,640-foot (500-meter) wide asteroid named Bennu, which circles the...

    Paging Bruce Willis! NASA is planning to launch a probe to study an asteroid that could one day pulverize the Earth. The asteroid, named Bennu, crosses Earth’s orbit once every six years and has gotten ever closer since it was discovered in 1999, astronomers told the Sunday Times of London (paywall). In 2135, Bennu will fly between the moon and Earth — a hair’s breadth in space terms, the Times reported. That’s so close that gravity from the Earth could effect Bennu’s orbit, “potentially putting it on course for the Earth later that century,” said Dante Lauretta, a professor of...

    The OSIRIS-REx spacecraft began its final approach toward the big near-Earth asteroid Bennu on Friday (Aug. 17), NASA officials said. The milestone also marks the official start of OSIRIS-REx's "asteroid operations" mission phase, they added. OSIRIS-REx is still about 1.2 million miles (2 million kilometers) from Bennu and won't arrive in orbit around the 1,650-foot-wide (500 meters) space rock until Dec. 3. The $800 million OSIRIS-REx mission — whose name is short for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer — launched on Sept. 8, 2016, from Cape Canaveral Air Force Station in Florida. If all goes according to...

    Boston - It was a normal Friday morning in the industrial city of Chelyabinsk, Russia. Adults were on their way to work, and children were in school. But that ordinary day was about to become extraordinary. Suddenly, a fireball shot across the clear morning sky leaving a thick trail of smoke, accompanied by the sound of a huge explosion. The shock wave knocked people over, shattered glass, and collapsed a factory roof. As many as 1,200 people were injured. A global network of infrasound sensors designed to pick up nuclear explosions calculated that the boom was 30 to 40 times...

    For 10 days this month, OSIRIS-REx will investigate whether or not Trojan asteroids exist at certain points in Earth’s orbit called Lagrange points. Though Jupiter has Trojan asteroids, it’s unclear whether or not Earth’s Lagrange points host similar objects. After all, only one Earth Trojan has ever been found. “The Earth orbits around the Sun, and the Earth has a gravitational field and the Sun has a gravitational field,” explained Dante Lauretta, OSIRIS REx’s principal investigator. “Because of that property, there are certain points in space where those two fields balance each other out, called Lagrange points.” OSIRIS-REx will be...
