Today marks Martian New Year. The length of a Mars year is almost double an Earth year. Like Earth, Mars is tilted causing seasons. Martian New Year occurs on Mars’Northern Spring Equinox. We have a video today showing the seasons on Mars. The movie combines animated images from MARCI (MArs Color Imager) http://www.msss.com/msss_images/latest_weather.html – where you can see from the Mars Reconnaissance Orbiter’s orbit how the tilt of Mars changes over its seasons.
