The overall goal of PolarNOx is to determine the altitude profile of nitric oxide (NO) in the polar night. NO is created by aurora. In a sunlit atmosphere, NO would be destroyed in about one day. But in the polar night it is expected that the NO abundance can grow to large values. At present we a have a poor understanding of how much NO is produced in the aurora and how it is distributed in altitude. We know that in some years, the polar night NO is transported to lower altitudes where it catalytically (i.e. very efficiently) destroys ozone. More ...

MISSION STATEMENT: “The visible light produced in the atmosphere as aurora is the last step of a chain of processes connecting the solar wind to the atmosphere. We are seeking to understand what structure in these visible signatures can tell us about the electrodynamics of processes higher up.” – Kristina Lynch To follow the Lynch Launches: http://isinglassmission.blogspot.com More ...

MISSION STATEMENT: “Electric fields drive the ionosphere which, in turn, are predicted to set up enhanced neutral winds within an aurora arc. This experiment will seek to understand the height dependent coupling processes that create localized neutral ‘jets’ within the aurora and their associated heating and neutral structuring.” – Robert Pfaff More ...
