SIGINT(SignalIntelligence) satellite is used to detect, intercept a nd locate electromagnetic(EM) signals radiated by systems such as ground radar, communication and TT&C systems.
The bright colors on the blue background indicate that an anomalous signal was received here on Earth by a radio telescope involved in a Search for Extraterrestrial Intelligence (SETI).
Perfecting a robot that bridges the gap will call for advances in almost every facet of modern robotics: artificial intelligence, machine vision, mechanical and electrical design, signal processing.
