Question Could Schumann Resonance Be Used for Planetary Exploration & Deep Space Communication?

[SankhaDn]

Schumann resonance has been of growing interest to researchers on Earth, but could it be harnessed for planetary exploration? Given the existence of subsurface oceans on Europa or Enceladus, could electromagnetic resonance help us detect hidden water bodies or even biological activity?

Additionally, could extremely low-frequency (ELF) signals offer an alternative for deep-space communication where traditional radio waves face limitations? NASA has explored ELF for underwater comms—could it work in deep space, too?

Would love to hear thoughts from planetary scientists, engineers, and enthusiasts!

Many things resonate when we hit them with a strong beam of energy, always a possibility for exploration sake.
ELF shows lowest possible loss in a dielectric and is essential to talk with our nuclear subs deep under highly conductive salt water. They don't mind the extremely low bit rate. In space, no such advantage exists thus the low bit rate would be prohibitive. ELF might be used to transmit data between a surface probe on Enceladus and a bot that melted its way through the ice to reach water.
