During their 13-hour flight across the South Pacific, the team detected secondary cosmic rays in the passenger compartment almost 40 times stronger than on the ground below. Their "haul" of radiation included a significant number of neutrons captured in portable bubble chambers. Read Spaceweather.com for the full story.
