A rover explored a crater on Mars and found several signs that the planet once had water. The crater contained a shiny mineral called hematite. On Earth, this mineral is formed in water. Also, the bedrock in the crater wall was layered, suggesting that the wall was eroded by wind, water, or volcanic lava flows. The rover studied one rock in the crater "El Capitan." The rock had pockmarks, similar to those an Earth rock would develop in the presence of salt. Do It! Scientists _________ that water was present on Mars.
