Using neutron-computed tomography, UC Davis researchers helped identify where hydrogen, and therefore water-rich fragments, resides in the meteorite without breaking it open. The meteorite may produce an other "gold" rush! 2014). April's interplanetary arrival triggered another gold rush of sorts, as a loosely knit consortium of scientists, meteorite hunters, and … Detection of the falling meteor by Doppler weather radar allowed for rapid recovery so that scientists could study for the first time a primitive meteorite with little exposure to the elements, providing the most pristine look yet at the surface of primitive asteroids. It's now called the Sutter's Mill meteorite, SM for short, named for the area landmark that triggered the 1848 California gold rush. Estimates indicate the meteor was about the size of a minivan. Classification: Carbonaceous chondrite (C) [9], The meteorite type is similar to that of the 1969 Murchison meteorite in Australia. We had radar data almost immediately, knew there were rocks on the ground, and…I had an early final exam the Thursday after the fall. A new, detailed study has traced the origins of this rock with unusual precision, and it has been revealed that it came down at record-breaking speed. [6][7] The name comes from the Sutter's Mill, a California Gold Rush site, near which some pieces were recovered. During the 2012 Lyrids meteor shower, a bolide and sonic boom rattled buildings in California and Nevada in daylight conditions in the early morning at 07:51 PDT on 22 April 2012. Fell: 22 Apr 2012. So far, less than a kilogram of meteorite material has been collected. Observed fall: Yes Year fell: 2012 Country: United States Mass: 993 g Classification history: [9], The Sutter's Mill meteorite is used to test sample collection and analysis procedures for NASA's OSIRIS-REx sample return mission.[9]. This fireball heralded the arrival of a mini-van sized space rock which entered the Earth’s upper atmosphere and burned up over Sutter’s Mill in Coloma, California, and dropped meteorites across streets and backyards throughout the Coloma-Lotus Valley. It’s believed Sutter’s Mill broke off from that asteroid anywhere between 50,000 to 90,000 years ago. Eyewitnesses watched the Sutter’s Mill meteorite streak across California’s daytime sky on Earth Day 2012. The Sutter’s Mill meteorite fall was in most probability a once-in-a-lifetime experience – an opportunity to bring something extraordinary to science, as it is likely the oldest material known to man. Were they seeing a reenactment of a process that supplied the early earth with the building blocks of life? The Sutter’s Mill meteorite streaking through the sky. The orbit had a shallow inclination and an orbital period suggesting that this meteoroid originated in the 3:1 mean motion resonance with Jupiter. 7:51am (PDT). No injuries were reported [1] although the sonic boom upon its disintegration rattled numerous houses and windows and further afield was heard throughout Central New York and was registered by seismographs. The air burst had approximate coordinates of 37°36′N 120°30′W / 37.6°N 120.5°W / 37.6; -120.5.[2]. Marc Fries, Ph.D., has a … Before entry, the meteoroid moved on an eccentric orbit, stretching from just inside the orbit of Jupiter to the orbit of Mercury. This is now known as the Sutter’s Mill Meteorite, the location famous for its association with the California Gold Rush. Similarly, the secondary carbonate mineral dolomite was utilized by Jilly et al. NASA Press Release on the Sutter’s Mill meteorite. The Sutter's Mill meteorite turn to be a rare meteorite type. The Sutter's Mill meteorite was seen by many eyewitnesses over the foothills of the Sierra Nevada range in California. No injuries were reported although the sonic boom upon its disintegration rattled numerous houses and windows and further afield was heard throughout Central New York and was registered by seismographs. The Sutter's Mill meteorite is a carbonaceous chondrite which entered the Earth's atmosphere and broke up at about 07:51 Pacific time on April 22, 2012, with fragments landing in the United States. The Sutter's Mill meteorite is a carbonaceous chondrite which entered the Earth's atmosphere and broke up at about 07:51 Pacific time on April 22, 2012, with fragments landing in the United States. [2] The American Meteor Society received 181 reports (an example of citizen science), and the fireball was sighted in New York, Maryland, Minnesota, Ohio, Ontario, Pennsylvania, and Virginia on Wednesday, December 2, 2020 around 17:08 UTC. The Sutter's Mill meteorite (now it's official name) was by some definitions a small asteroid, roughly 2.5 to 4 meters (8-13 ft) in size and weighing in the neighborhood of 40 metric tons (88,000 lb). The unique rock came from a dark, carbon-rich asteroid that experienced an unexpectedly large variety of geological processes on its surface. This fireball heralded the arrival of a mini-van sized space rock which entered the Earth's upper atmosphere over Sutter's Mill California and dropped meteorites across streets and backyards. Sutter’s Mill meteorite is a so-called carbonaceous chondrite which is much more diverse in its composition than other meteorites of this type. The Sutter's Mill Meteor on 4/22/2012 was captured on video from Southern California. Unlike Murchison, Sutter's Mill shows clear brecciation: fragments of CM lithologies with different aqueous alteration and thermal processing histories are embedded in a fine grained CM matrix material.
