    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...

    Tuesday, October 20 1:20 to 6:30 p.m. – Live stream animation displaying OSIRIS-REx’s sample collection activities in real time. The animation commences with the spacecraft’s slew into position for the Orbit Departure Maneuver and runs through the entire sequence of TAG events, concluding after the spacecraft’s back-away burn. Event will be broadcast on the mission’s website. 5 to 6:30 p.m. – Live broadcast from Lockheed Martin of OSIRIS-REx’s descent to the surface of Bennu and attempt at sample collection. Hosted by Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, and Michelle Thaller, science communicator at Goddard, the broadcast...

    Explanation: What would it be like to land on an asteroid? Although no human has yet done it, NASA's robotic OSIRIS-REx spacecraft is scheduled to attempt to touch the surface of asteroid 101955 Bennu next week. The goal is to collect a sample from the nearby minor planet for return to Earth for a detailed analysis in 2023. The featured video shows what it looks like to descend toward the 500-meter diamond-shaped asteroid, based on a digital map of Bennu's rocky surface constructed from image and surface data taken by OSIRIS-REx over the past 1.5 years. The video begins by...

    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...

    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...

    On a distant space rock being explored by a NASA probe, days are slowly shortening — and scientists are still trying to figure out why.Right now, the asteroid known as Bennu is spinning once every 4.3 hours. But scientists working on NASA's OSIRIS-REx mission to the space rock have used data gathered before the probe's arrival to calculate that Bennu's rotation rate is speeding up over time — by about 1 second each century."As it speeds up, things ought to change, and so we're going to be looking for those things and detecting this speed up gives us some clues...
  • No, You Won’t See an 'Apocalypse Asteroid' in the Sky on Valentine's Day

    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),...
