Hardware in orbit and on the ground
Next to Rocket and Planet, this category is the practical one: it covers the equipment that sends and receives signals. Half of it floats in space, half stands on the ground as dishes, field terminals and rugged handsets. That makes it a better source than general space imagery for telecom offers, rural broadband pages, navigation apps or emergency kit lists.
What to look for
Solar panels are thin and reflective, so a good cut-out keeps their grid lines crisp and leaves no dark fringe around the frame. For interface icons, pick the simple dish with two or three signal arcs; the detailed orbital renders only work large, on a hero banner or a science poster.
