I’ve seen articles about underground water being detected in planets like Mars. I’m assuming it’s detected via satellite (microwaves?), but how does the technology work?
And are we using the satellite that’s orbiting around earth and projecting the (microwaves?) there, or do we send a few satellites specifically to Mars to do these investigations?

I think there is one method we’re you watch something like a meteor slam into and shoots dust up into the atmosphere that we can analyze the spectrum of light going through it from the sun. Different materials give you a different spectrum
