Layers tell a story. A story of what conditions might have been like in the ancient past, and that’s true of both Earth and Mars. On Mars, the layers might be better preserved since the planet is not as geologically active as our world. But of course, the Martian wind is relentless over the aeons.
This image shows some layered material in Tempe Fossae. Fossae is a word that is used to indicate large troughs when using geographical terminology related to Mars. The troughs of Tempe Fossae are about 2,000 kilometers in length. Our observation was done in conjunction with the CRISM instrument onboard the Mars Reconnaissance Orbiter, which is an imaging spectrometer. The data we get from both instruments can give us a fuller picture of the layers and their composition.
