How do space probes transmit data back to Earth across vast distances?
In: Planetary Science
As radio. Radio, being electromagnetic radiation, travels as fast as it’s possible for any information to– the speed of light. The probe is designed to transmit as narrow a broadcast as possible and to keep each bit of data going for a while so that our receivers on Earth have as good a chance as possible of picking up the signal, which means it’s still a pretty slow connection.
