The analysis software that NASA uses to inspect photographs of the Earth is starting to recognize changing events on our planet's surface, like Spring thaws, snowfalls and volcanic eruptions. In fact, the software is now giving orders back to NASA's Earth Observing-1 satellite on where it should be pointing its camera. The software has taken more than 1,500 photographs of frozen lakes and can recognize when the ice has melted. Software like this could be used to track changing events on other planets, like dust storms on Mars or search for ice volcanoes on Europa.
