Got your party hats ready? May 5 marks … the Martian New Year. That seems a little odd since we’re in the middle of Earth’s year, but there’s a reason Mars’ date falls where it does.
NASA usually measures time in the solar system against the Earth standard — where our planet takes 365 days to go around the sun.
Mars orbits farther from the sun than Earth does. One year there takes 687 Earth days, or almost 23 months.
To celebrate, NASA is in Mars, Pennsylvania, for a few days of science and technology exhibits about Mars exploration. Yes, it’s not the real Mars, but the weather should be much nicer, and there’s still parking for spaceships.
