2.   The colors offer insight into mineral composition of the soil and rocks.

3.   The spacecraft is equipped with instruments designed to map the mineral composition of the rugged Martian surface, search for evidence of underground water and measure radiation levels.

4.   The thermal imager was designed specifically to identify the mineral composition of Mars, including carbonates and other substances that form on Earth in the presence of water.

5.   Zandee said the low gold recoveries appeared to be due to changes in the mineral composition of the ore.
