in reply to Mars Cydonia face to face

So according to Mars24 The Face on Mars will point to Los Angeles at 8pm on 12/23/2011 an early evening event but in six months jun 23 2012 it'll be like 6pm. Seems every six months it goes back two hours of Earth time, time slip don't you know.

      It's figure the Earth nighttime and daytime mars cycle of

      mars facing Earth in daytime or nighttime.

      I got every two years mars falls behing earth 62 days

      so on sept 22 2011 mars was setting to night and

      on sept 23 2012 mars rises again as day face then

      add 62 days nov 25 2014 mars rises as day face

      two years later BooM! predictable !!!!!!!

      Jan 27 2016 mars rises to day face

      mar 29 2018 mars rises to day face

      and on odd years in nighttime face

      sept 23 2013 night face

    Yes, It's like moon phases, only on a Martian 668.5991 day year timescale. Why don't you ask JPL for a formula?

      Wouldn't it need a Logarithm formula? Like the degrees in or out of phase with the Earth prime meridian 0 degrees at any date in the future and L.A. lat. 34 long. -118 Hmmmm

        If it's two hours of time slip every six months that's 668.5991 mars year / six months 180 days = 3.714 two hour time slips (not right) because then it's only 6 hours of slip not 24 so try two hours of earth slip backwards every 111 Martian days.
