This meteorite came from space. We sent it back again.  On Aug 15, 2026, the students of Earth to Sky Calculus launched it to the stratosphere onboard a cosmic ray research balloon, more than 102,010 feet above California's Sierra Nevada mountains.

This is a Campo del Cielo ("Field of Heaven") meteorite fragment unearthed in Argentina. Scattered across 1,000 km, Argentina's Campo del Cielo craters are four to five thousand years old. They were reported to the general public in 1576, but were already well-known by Aboriginal peoples. The craters and surrounding areas contain many fragments of an iron meteorite. So far, 100 tons of fragments have been recovered, the most of any meteorite finding.
 
During the 3 hour flight, this fragment experienced temperatures as low as -55 C and air pressures less than 0.07% of sea level. According to onboard radiation sensors, cosmic ray levels were 100 times Earth-normal as the pendant reached the top of our planet’s atmosphere and touched the edge of space. After the balloon exploded (as planned), the payload parachuted back to Earth and landed in the White Mountains overlooking Bishop, CA.
 
The students are selling space pendants to pay the helium bill for their cosmic ray ballooning program. Each one comes with a greeting card showing the jewelry in flight and telling the story of its trip to the stratosphere and back again.
