The last paragraph, concerning Gangale orbits and modifications to the US Presidential Primary, seems offtopic for this page. Move to a seperate entry on Thomas Gangale? Alba 03:39, 2 Apr 2004 (UTC)

New Mars and other planet's calendar

Whoa, I've found new version of Mars and other planet's calendar! Just call me if you want to know more....

NO ZERO

In the dates, there's no zero. There should be. 2404:3C00:502F:4C80:55D:7EA:DA89:E90A (talk) 05:37, 4 March 2021 (UTC)[reply]

That's just, like, your opinion (and mine), man. —Tamfang (talk) 00:05, 12 July 2024 (UTC)[reply]

Important Dates Table Conversion

Is there a source for the "Important dates in Martian history", or were all of these conversions done by hand? Perhaps someone can correct my math, but the conversions appear to use a fairly low degree of precision. To take the Viking 1 landing date as an example:

  Earth Epoch (Julian):        0
  Mars Epoch (Julian):         587311
  Viking 1 Landing (Julian):   721555

Thus the Viking 1 Landing, in Earth days but adjusted to the Martian epoch, would be:

  721555 - 587311 = 134244

Now as per the Timekeeping on Mars article, we have the following lengths for Martian and Terran solar days, respectively:

  Mars solar day:  24 h 39 m 35.244 s (88,775.244 seconds)
  Earth solar day: 24 h 00 m 00.002 s (86,400.002 seconds)

This means the conversion between the two should be, exactly:

  88,775.244 seconds per sol / 86,400.002 seconds per day = 1.02749122622 sols per day

Thus to convert the Julian date of the Viking 1 lander we previously adjusted to the Martian epoch from Earth days to Mars days, we should get:

  134,244 days / 1.02749122622 sols per day = 130652.210524

However, on the page the "Mars Julian date" for that event is 130,584. Unless I've done my math wrong somewhere, that's a pretty significant margin of error. If we work backwards,

  134,244 days / 130,584 sols = 1.02802793604

Not a super precise conversion factor. Off by almost 1/2 a percent. 67.250.117.56 (talk) 14:25, 21 January 2024 (UTC)[reply]
