It's slightly larger than a 5-liter water bottle, and is whizzing around the Earth at a speed of 7.5 kilometers per second. The satellite has two cameras built into its body, and can be controlled quickly and turned smoothly in all directions.
HYPSO-2 has a special job, monitoring algae. Large algae blooms can cause major damage, poison drinking water and mass fish deaths.
"The new satellite means about a 10-fold increase in the capacity to monitor water quality, algae blooms, and other important ocean phenomena," says Bjørn Egil Asbjørnslett, a professor and director of NTNU's Ocean and Coast strategic research area.
"Another advantage of letting satellites capture data is that it means less emissions into the sea from research ships and other marine vessels," he said.
