Pegasus ICON Starboard Black Light Inspection

A technician performs a black light inspection of the Orbital ATK Pegasus starboard on May 22, 2018, prior to fully mating NASA's Ionospheric Connection Explorer (ICON) to Pegasus inside Building 1555 at Vandenberg Air Force Base in California. The explorer will launch on June 15, 2018, from Kwajalein Atoll in the Marshall Islands (June 14 in the continental United States) on the Pegasus XL, which is attached to the company's L-1011 Stargazer aircraft. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where terrestrial weather from below meets space weather above. The explorer will help determine the physics of Earth's space environment and pave the way for mitigating its effects on our technology and communications systems.
