ESA has announced the success of the mission of its GomX-4B nanosatellite in testing new miniaturized technologies that allow really tiny satellites to navigate in space thanks to tiny liquid butane propellers and the positioning system called star tracker to use instruments such as HyperScout, a hyperspectral camera. So far, CubeSat nanosatellites were normally devoid of propulsion systems so this one opens a new era by proving that there are cases in which a shoebox-sized satellite can do the job that until now was the prerogative of satellites hundreds of times more massive with enormously lower costs.
