Mars Express — the first European spacecraft built to investigate another planet — has been snapping color and 3D images of Mars for 10 years.
To honor the Martian anniversary, the European Space Agency has released a spectacular new fly-over video of Mars showing off some of the striking images captured by the Mars Express spacecraft from its place in orbit.
The flood plain in the video is called Kasei Valles, and scientists think it was created during intense flooding events on Mars, ESA officials wrote in a description. The entire video covers an area of about 598,000 square miles (1.55 million square kilometers), which is about equal to the size of Mongolia. Kasei Valles is one of the biggest outflow channels on Mars.
