The tenth SpaceX cargo resupply launch to the International Space Station (ISS), targeted for launch Feb. 18, will deliver SAGE III to measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere. Understanding these measurements will allow national and international leaders to make informed policy decisions regarding the protection and preservation of Earth's ozone layer. Ozone in the atmosphere protects Earth's inhabitants, including humans, plants and animals, from harmful radiation from the sun, which can cause long-term problems such as cataracts, cancer and reduced crop yield. During Expedition 45, ESA astronaut Andreas Mogensen captured pictures of blue jets, elusive electrical discharges in the upper atmosphere, with the most sensitive camera on the orbiting outpost to look for these brief features.
