About one million years ago, this meteorite landed in northern Sweden. On Aug. 25, 2026, we sent it back. It flew to the edge of space on board a cosmic ray research balloon, 100,860 feet above the Sierra Nevada mountains of central California. 
 
This is a spherical fragment of the Muonionalusta Meteorite found near the Muonio River in Sweden. It is contained within a sterling silver cage that hangs from a matching 18-inch chain.
 
The meteorite comes with a certificate of authenticity, but you can see that it's real using your own eyes. The sphere is crisscrossed by a unique pattern of geometric crystal lines formed by millions of years of slow cooling in space.
 
During the nearly 3 hour flight, the pendant experienced temperatures as low as -57 C and air pressures less than 0.08% of sea level. According to the radiation sensors inside the payload, cosmic ray levels were 100 times Earth-normal. After the balloon exploded (as planned), the payload parachuted back to Earth, landing in Death Valley Wash on the outskirts of Death Valley National Park.
 
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 necklace in flight and telling the story of its trip to the stratosphere and back again.
