On Jan. 19, 2019, the students of Earth to Sky Calculus launched a cosmic ray balloon to the stratosphere. This rose went along for the ride. The bloom is laser-etched into a block of optical-quality borosilicate crystal with the words "I Love You" curving below the stem. The balloon traveled 104,843 ft feet above the Sierra Nevada mountains of central California, then parachuted back to Earth, landing near the eastern edge of Death Valley National Park.


The rose had a wild ride and the students got great cosmic ray data for their atmospheric radiation monitoring program.


Each rose comes with a greeting card showing the item in flight and telling the story of its journey to the edge of space. Also included is a rotating LED stand that fills the bloom with 4 luminous colors.
