(meteorobs) meteorobs OT Question

[Chris Peterson]

They don't have to be big. The thing about VLF is that you can detect 
the magnetic component rather than the electric. I've made very 
sensitive VLF detectors using 20 or 30 cm long ferrite rods wrapped with 
thousands of turns of wire, feeding into a simple audio frequency range 
amplifier. Processing is simple.

Not that one of these is on the Mars rovers or orbiters, but in 
principle they could be.
