This Science On a Sphere (SOS) module is designed to help the public better understand the story of water on Mars and how we're learning more about it. It portrays the mystery of what happened to the water on Mars in the context of a detective... (View More) story. NASA's MAVEN mission (Mars Atmosphere and Volatile EvolutoN) will help solve this mystery by studying the Martian atmosphere, how it has changed over time, and how it interacts with the Sun and the solar wind. The module also delves into Mars exploration, featuring past, present, and future Mars missions, and includes an activity comparing images of water-related features on Earth and Mars. It will help people understand that a planet's climate can change over time and how learning more about Mars helps us learn more about Earth and other planets as well. Resources included are: script, SOS playlist and datasets, background and tips for the docent or facilitator, and image comparisons of water-related features on Earth and Mars. (View Less)

It shows Mars during the transition between spring and summer in the northern hemisphere (summer solstice). The north polar carbon dioxide (dry ice) frost cap is rapidly evaporating from solid to gas, revealing a much smaller permanent water ice cap. Bright water ice clouds are visible across the center and along the bottom of the image. (View Less)
