De lyckliga ingenjörerna - Approaching Zero,000 (1987)

For five years and across four continents, Stefania Lopez Svenstedt and Carl Henrik Svenstedt follow a Swedish engineering group that builds Sweden's first spacecraft: the research satellite Viking. The purpose of the satellite is to explore the Aurora Borealis, the northern lights, a magnetic storm that flares up when particles of the solar wind enter the atmosphere at the Earth's magnetic poles.
