Outer space - an infinite expanse with many opportunities for science. In which areas can research be carried out under zero gravity? What plans are there for medium and long-term projects? What funding is available? One hundred and twenty representatives from science, industry and politics discussed these issues at a two-day workshop organized by the Max Planck Institute for Extraterrestrial Physics. The aim of the event, held at the Bavarian Ministry for Economic Affairs, was to prepare a strategy paper on national aerospace.
