Thunderstorms in space holds climate information

From it's position at ISS 400 km above the Earth ASIM will look into phenomena in the atmosphere powered by thunderstorms. ASIM will both survey thunderstorms and lightning above the clouds and the processes that power them. In this way new knowledge can be obtained about both this phenomena and climate related processes in the atmosphere. Picture: DTU Space/NASA

Denmark can finally call itself a full member of the international space-faring community with the successful completion of Andreas Mogensen's mission to the Internation Space Station (ISS) in September. Since his return researchers at DTU Space have been busy processing the pictures he took of storm clouds and lightning as part of the Thor project. The results are beautiful to behold and far exceed the research team's expectations. Picture:ESA/Andreas Mogensen/DTU Space
