    When Suzy Kop entered her father's bedroom on May 8, 2023, she was stunned to find a grapefruit-sized rock next to a big dent on the wooden floor. Upon further investigation, the New Jersey resident saw two holes in the ceiling. It appeared that the stone had struck the floor with such great force that it rebounded and punched a second hole before landing back.

    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...

    NASA’s OSIRIS-REx spacecraft was launched in 2016, but today it will begin to orbit its destination: the asteroid Bennu. When it does, Benniu will break the record for the smallest object ever orbited by a manmade spacecraft. NASA will begin a process of learning more about the small asteroids that reside in our part of the solar system. You can watch the livestream of the arrival here:

    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...

    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 Hypatia stone, as it is known, is not only extraterrestrial in origin. It contains micro-mineral compounds not known to occur anywhere on Earth, not found in any other meteorites, and not known to occur anywhere in the Solar System. It's a discovery that raises some questions about the formation of the Solar System. Subsequent analysis revealed that the diamond-filled stone was not from any known comet or meteorite - its combined features were unique among known extraterrestrial materials. One hypothesis proposed that it might be a fragment of comet nucleus, shocked on impact, and another found that it was...

    > The minerals, including sulfur, copper, zinc, iron and precious metals, are contained in volcanogenic massive sulfide (VMS) deposits that form on the ocean floor where tectonic plates pull apart and allow magma (molten rock) to invade the Earth's 3.7-mile- (6 kilometer-) thick crust. The magma heats seawater to 662 degrees Fahrenheit (350 degrees Celsius) and moves it through the ocean crust via convection; and the seawater deposits the minerals where it discharges along the ridge axis. >

    Finding dinosaurs in Antarctica is both easier and harder than finding them on another continent. Easier, because like looking for meteorites, dinosaur bones show up against the stark landscape. Harder, because the dinosaur's cold-bloodedness wouldn't have lasted long prior to continental drift and climate changes. Antarctic Lost Worlds Tale of Two Dinosaursbased on National Science Foundation report Against incredible odds, researchers working in separate sites, thousands of miles apart in Antarctica have found what they believe are the fossilized remains of two species of dinosaurs previously unknown to science.

    Space mining has been a longtime staple of science-fiction films — and the companies are almost always the villains. The transport ship in "Alien" was towing a load of ore when sinister, corporate overlords diverted it into the clutches of the galaxy's baddest monster. "Avatar" was all about saving the inhabitants of Pandora from thugs clawing their home planet to shreds in search of "unobtanium." Nevertheless, a group of entrepreneurs received a hero's reception Tuesday in Seattle, when they unveiled a new company with the goal of extracting platinum, gold and other valuable resources from asteroids.

    ROME and BOSTON - Scientists from Boston University's Center for Space Physics reported today that NASA satellites designed to view the escaping atmosphere of the Sun have also recorded evidence of gas escaping from the planet Mercury. The scientists reported these findings at the European Planetary Science Congress (EPSC) meeting in Rome, Italy this week. The STEREO mission has two satellites placed in the same orbit around the Sun that the Earth has, but at locations ahead and behind it (STEREO, or Solar TErrestrial RElations Observatory, is the third mission in NASA's Solar Terrestrial Probes program). This configuration offers multi-directional...

    Dinosaur Deaths Outsourced to India? Boulder, CO, USA - A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico. The eruptions, which created the gigantic Deccan Traps lava beds of India, are now the prime suspect in the most famous and persistent paleontological murder mystery, say scientists who have conducted a slew of new investigations honing down eruption timing. "It's the first time we can directly link the main phase of the Deccan Traps to the mass extinction," said Princeton University paleontologist Gerta Keller....

    A fossil discovered in Montana has given new momentum to the hypothesis that dinosaurs were thriving right up until a devastating meteor hit Earth 65 million years ago, causing their extinction. Scientists from Yale University have found what is believed to be the youngest dinosaur fossil ever found, thought to be from just before the mass extinction took place. The discovery, described in a study published in the online edition of the journal Biology Letters, contradicts the theory that the dinosaurs slowly went extinct before the cosmic impact. The fossil -- a 45-centimetre horn believed to be from a triceratops...

    No, no, no. No no no no no no no no. No, no. No. Fox News broke the story, which ought to make one immediately suspicious — it's not an organization noted for scientific acumen. But even worse, the paper claiming the discovery of bacteria fossils in carbonaceous chondrites was published in … the Journal of Cosmology. I've mentioned Cosmology before — it isn't a real science journal at all, but is the ginned-up website of a small group of crank academics obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down...
  • Asteroid Breakup May Have Doomed Dinosaurs

    It’s a disaster scenario that Hollywood has picked up on (think Deep Impact). An incoming object menaces the Earth. Scientists try to destroy it with nuclear weapons, but the horrified populace soon discovers that the blast has simply broken the object into pieces, each with the potential to wreak havoc planet-wide. Now we learn that an impact between two asteroids causing a similar crack-up may have resulted in the cataclysmic event some 65 million years ago that destroyed the dinosaurs. Researchers from Southwest Research Institute and Charles University (Prague) have been studying the asteroid (298) Baptistina, combining their observations with...

    Abundant tiny particles of diamond dust exist in sediments dating to 12,900 years ago at six North American sites, adding strong evidence for Earth's impact with a rare swarm of carbon-and-water-rich comets or carbonaceous chondrites, reports a nine-member scientific team. These nanodiamonds, which are produced under high-temperature, high-pressure conditions created by cosmic impacts and have been found in meteorites, are concentrated in similarly aged sediments at Murray Springs, Ariz., Bull Creek, Okla., Gainey, Mich., and Topper, S.C., as well as Lake Hind, Manitoba, and Chobot, Alberta, in Canada. Nanodiamonds can be produced on Earth, but only through high-explosive detonations or...
