Sutter's Mill meteorite

This … 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. This was the second recovered find. Fragments of the Sutter’s Mill meteorite fall collected by NASA Ames and SETI Institute meteor astronomer Peter Jenniskens in the evening of Tuesday April 24, 2012, two days after the fall. The Sutter’s Mill meteorite which is a carbonaceous chondrite is believed to contain valuable clues on the solar systems composition and formation.

The meteorite is estimated to have been traveling at 28.6 ± 0.7 km/s per second and reached peak brightness at 35 miles above the ground before breaking up at about 30 miles above ground. A close-up of the Sutter's Mill Meteorite, a fragment from a daytime fireball that exploded over parts of California and Nevada on April 22, 2012. This is now known as the Sutter’s Mill Meteorite, the location famous for its association with the California Gold Rush. The Sutter's Mill meteorite was seen by many eyewitnesses over the foothills of the Sierra Nevada range in California. This was the largest meteoroid impact over land since asteroid 2008 TC3.Meteor astronomer Peter Jenniskens assigned SM … The unique rock came from a dark, carbon-rich asteroid that experienced an unexpectedly large variety of geological processes on its surface. Using neutron-computed tomography, UC Davis researchers helped identify where hydrogen, and therefore water-rich fragments, resides in the meteorite without breaking it open. It's now called the Sutter's Mill meteorite, SM for short, named for the area landmark that triggered the 1848 California gold rush. 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. 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 name comes from the Sutter's Mill, the California Gold Rush site, near which some pieces were recovered. Meteorites like Sutter’s Mill are thought to have delivered oceans of water to the Earth early in its history. Image credit: NASA Ames/Eric James. April's interplanetary arrival triggered another gold rush of sorts, as a loosely knit consortium of scientists, meteorite hunters, and … The scientists published th The Sutter's Mill meteorite—named for the nearby site of the 1848 gold strike that triggered the California gold rush—immediately caught the attention of astronomer Peter Jenniskens of the SETI Institute and NASA Ames Research Center in Mountain View, California. The meteorite may well be astronomer’s gold too, thought to be a rare CM type carbonaceous chondrite , a type rich in organic compounds and similar to the Murchison Meteorite.
