Looking For Pieces Of The Meteorite

I was sorry I slept through the spectacle in the sky on April 22nd, but at least I saw the zeppelin floating around this week:

The meteorite did not arrive quietly early on that Sunday morning. Residents throughout the Sierra Nevada, from Lassen to Kernville, reported hearing explosive sounds as it burned in the atmosphere. Many saw a bright white streak in the sky.

The track of that streak ended around Marshall Gold Discovery State Historic Park in Coloma, where pieces of the meteorite were found in the parking lot. It was here, in 1848, that gold was discovered in the American River's south fork, touching off the legendary Gold Rush that transformed California and the West.

In honor of the location, scientists have dubbed it the Sutter's Mill Meteorite. They estimate it must have been about the size of a minivan, and weighed around 150,000 pounds, before it broke up.

...Which helps explain why the scientists did not hesitate to charter Eureka, the only zeppelin in North America, which conveniently shares space with the NASA Ames Research Center at Moffett Field near San Jose.

...Scientists say the meteorite is probably the most significant event of its kind since the late 1960s. That is because it likely is composed of carbonaceous chondrite, the earliest solid material to form in our solar system more than 4 1/2 billion years ago, before the planets took shape.

...Scientists will likely probe these samples for decades in search of clues about the universe and life itself. The last major carbonaceous chondrite find occurred in Australia in 1969 – the same year Americans first landed on the moon – and scientists have been learning from those samples ever since.

"This material is unique. It's capturing the very first moments of planet formation," Yin said. "It is, perhaps, one of the most primitive objects you would ever hope to find."
