Starlink satellites are relatively small compared to others in orbit. The unit is about the size of an office desk, weighing +- 260kg). Each satellite features a single solar array and 4 powerful phased array antennas. For propulsion purposes the satellites are equipped with ion thrusters, powered by krypton that enables the satellites to orbit,...
