Satellite launchers are currently shuffling with two very different realities: on the one hand, the operators traditional market, with its moderately heavy loading market. On the other, the explosion of demand for low orbit (LEO) smaller devices, which obliges them to reconvert. Companies already known in the segment, as well as start-ups that are added to the "fever" by LEO, aim to cheap launches, of a large number of satellites, and more sites with availability to send them to orbit.
