Mineral Fingerprinting Audio Files

Youth first listen to audio files of spectra for plant leaves here on Earth to try help distinguish differences between samples. Sample 1 is from an Aspen tree in the summer (green) and the second sample is from an Aspen tree leaf in the fall (yellow).

Youth first listen to audio files of spectra for 6 known minerals. Then, based on the audio files, they identify unknown minerals at 4 potential landing sites on Mars (Gale Crater, Iani Chaos, Jezero Crater, and Nili Fossae).

Today, we identified minerals at potential landing sites on Mars. Which site do you think has the most interesting minerals?

We can use data from known samples of minerals on earth to help identify minerals on other planets. Data can come in multiple forms, including audio, visual, and others.
