A Martian Year – at One Earth Month Intervals
I’m not exactly sure why this particular date is used but by international agreement astronomers have selected 11 April, 1955 as 0 degrees for year 1 of this Martian calendar. What this means is that on Tuesday October 8th, Earth time, it is the start of summer during year 35 using the aforementioned calendar system.

Nice image with Orion in the background. Would it really line up that way? I must admit that I can’t close my eyes and envision the perspective… but I still like it
