  • Analyzing & Interpreting Data 

Activity Overview

Youth interpret the spectra of reflected light to identify the water-based minerals at each of four potential landing sites, determining which location on Mars has the most evidence of past water. 

Guiding Question

How can interpreting mineral data help us choose a landing site on Mars? 

Youth Will Do

  • Interpret the unique spectral “fingerprints” of different minerals to identify them. 
  • Apply their knowledge of which minerals are evidence of past water when evaluating landing sites. 

Youth Will Know

  • Spectroscopy measures how much light of different colors (both visible and invisible) is emitted by or reflected from a material. 
  • There are many “colors” of light humans can’t see, but engineers build instruments to measure them.
