how is the information delivered from Mars to earth... beside telling me by radio waves... describe... 10x :D:D:D

What information? If you wanted to transmit information to earth, I can think of radio waves, light waves. Actually light waves and radio waves are very similar -- just different parts of the electromagnetic spectrum.

Hello g:

It's from the Martians tin hat directly into yours.

"Radio" waves & "light" waves are both the same phenomena : forms of electromagnetic radiation (only with different wavelengths)

What kind of information? Electromagnetic waves would cover just about all of them. Depending on which wave, you can determine the wavelength of the traveling wave. Also, know that any EM waves will travel at the speed of light.

I've been thinking about the question I think by satellites...

That could be done... but it will take lots of time and when the astronauts (in the satellite, better called space ships here instead of satellites) reach the Earth, there's the probability that they see an Earth much older than when they last saw it.

I would use light waves.
