Our friends over at Zooniverse Planet Four informed us that today is the Martian New Year. It’s not something we recognize every July 31 because years mark the time it takes for a plant to travel around the sun, and for Mars, that takes 668 days. So a Mars year is about twice as long as an Earth year. Scientists began to count Martian years on April 11, 1955. Since then the moment when Mars completes its turn around the Sun has shifted on our calendar from from April to July.
Planet Four is Zooniverse’s research project where you help scientists classify points of interest in images of Mars’ surface. Check it out!
