Esrange Space Center

Esrange Space Center is a rocket range and research centre located about 40 kilometers east of the town of Kiruna in northern Sweden. It is a base for scientific research with high-altitude balloons, investigation of the aurora borealis, sounding rocket launches, and satellite tracking. Built in 1964 by ESRO, one of the predecessors of the European Space Agency, the site is currently operated by the Swedish Space Corporation. An orbital launch complex, LC-3, has been built in the early 2020s.
