These Zinnia seeds flew to the edge of space 30 km above Earth’s surface aboard an helium balloon on Feb. 17, 2016. The seeds were exposed to comic ray doses more than 100x Earth normal, temperatures as low as -63C, and air pressures only 0.3% of sea level. Zinnias also have been grown on the International Space Station.
Seeds were planted in my home on April30. Growing incredibly well.:
