Wow - a robot probe? Really?
Apparently you’ve never heard of Spectrum Analysis (http://en.wikipedia.org/wiki/Spectrum_analysis) and - given that it is pretty basic stuff - *maybe* you shouldn’t be commenting on scientific matters...?
I guess you'd better educate the NASA folks who sent the rovers to mars. Better tell them about Spectrum Analysis and save us the money and them the effort of sampling the planet babyboy.
