Re: Martian Calender - I have created a martian calender...

On this day On This Day in Space! May 24, 1962: Scott Carpenter becomes 2nd American in orbit for 3 passes in just under 5 hours.

Carpenter was one of NASA’s first group of astronauts known as the "Mercury Seven." He was the backup pilot for John Glenn, who first orbited Earth three months earlier.

Re: Martian Calender - I have created a martian calender...

For SpaceNut re #630

Thanks for adding this interesting reminder of Scott Carpenter's flight!

Your post is a reminder for us all that there are already a number of "annual" (Mars style) anniversary opportunities.  The landers that have survived for impressive periods are candidates, but even those whose remains are scattered on the terrain are worth remembering occasionally.

It will take arrival of a new member in this forum, for us to see postings along these lines.

This is an invitation for any forum reader who is not yet a member, but would like to focus upon noting the special days that are slowly accumulating in the 35 Mars Years of serious human physical interaction with the planet. I am not unmindful of astronomical investigations of Mars, but they are (most likely) forever a part of Earth history.

Registration in this forum is not difficult.  However, due to the high volume of spam traffic, please post your first message with text that is meaningful in the topic you have chosen. 

***
SpaceNut ... this may be a good time to remind you of the fund raising opportunity our work here may provide for the Mars Society.

It is becoming increasingly clear (to me at least) that the calendar plan for a business calendar for Mars is practical.  The most propitious time for launch of a new combined Earth/Mars calendar is the well established Earth based calendar market.  Every year as we approach the new year, millions of individuals and businesses place orders for new Terrestrial calendars, so they can have them on the wall on January 1st.

While the Mars New Year will be occurring on February 7, 2021 (according to marsnewyear.com) it will be close enough so that it might provide a bit of extra interest for a Combined Earth/Mars calendar.

What I have in mind is a Mars Calendar with an Earth overlay.  It would be exactly what a Mars business person would want and need for onsite operations which must be coordinated with Earth suppliers and shipment opportunities.

I decided to send a contact form invitation to the folks who sponsor the marsnewyear.com web site, to see if they might be interested in a  joint project.

Proceeds would then be shared between the Mars Society and the educational activities of the marsnewyear.com organization.

Re: Martian Calender - I have created a martian calender...

For SpaceNut re Mars Calendar ....

Just FYI ... I'm looking for a publisher who might be interested in a cooperative partnership with the Mars Society to produce a combined Mars/Earth calendar.

https://www.browntrout.com/contacts

I'm working on a business calendar for Mars. There may be an audience for a calendar that combines the Earth traditional calendar with the 24 month designed calendar for Mars. You can evaluate the idea by visiting NewMars forums daily calendar

Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter

Re: Martian Calender - I have created a martian calender...

Mars is almost 60% complete along or away around its path. We are heading towards a mars winter of which the Insight page indicates we are warming not cooling for the day time temperatures which makes the page before post #554 of location incorrect. Something else that is on the page is that the air pressure drops with the rising temperature with the wind air speed rising during the mars day.

Mars year

Autumnal equinox (Ls = 180°)      Apr 08 2020   
Winter solstice     (Ls = 270°)       Sep 02 2020
Spring equinox     (Ls = 0°)      Feb 07 2021


According to the French web site this topic is following, today's sol is 430.

Solar Longitude: 214.9 is the value computed for location. 

Without doing anything more than just looking at the previous post with respect to the French web site, it looks to me as though reaching 270 degrees on September 2nd of this year (on Earth) is a reasonable prediction.

Thanks for keeping an eye on this topic!

As a reminder, I am hoping to find a publisher who might be interested in working on a Mars/Earth calendar.

So far I have written to only one publisher, but I have a set of six more I hope to get around to writing "soon".

Note: The difference in kilometers shown below is NOT computed at the same time every Earth day.
Minus prefix means Mars is approaching the Sun.
Distance of Mars from the Sun is given by this web site in kilometers:   209,907,183 km Difference -109930
Distance of Mars from the Sun shown in the previous Days report was: 210,017,113 km Difference -120626
Reference star: TYC 5249-975-1 Magnitude 8.32 in path

Sol 431 is in Month 16 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.

Sol 431 is Friday in the Proposed calendar for Mars.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees.
The next Skip Day will occur in June on Earth. A Skip Day occurs when the longer Mars Sol reaches 24 Earth hours.
For those who may be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter

Events of interest will be ON Mars, or relate to Mars. Examples are launches, landings, discoveries
