Mini satellites as environmentalists | STERN.de

Planet’s small satellites document climate damage and environmental changes and help with catastrophes such as those following the earthquakes in Turkey and Syria. But how exactly does it work?

The small satellite is as big as a two-liter milk carton and weighs about as much. Its outer shell made of aluminum plates shines matte in the office light; The artificial celestial body carries a solar module on two sides that can be folded out. An aluminum cylinder protrudes from the front, closed by a lid. As soon as the satellite reaches its orbit in space, the lid opens and light shines inside the instrument.
