Thanks for telling us of Santa's journeys, and preparations for the days ahead!
Best wishes to all in your family, in your neighborhood including the grumpy neighbor, and to everyone in the forum membership.
We have a lot going on that will come to fruition in 2024, and it will be good to have everyone present to observe, to comment upon and perhaps even to guide some of those activities.

]]>Christmas is December 25, but the Bible says Christ was born in spring. Under the Julian calendar December 25 was the winter solstice. Romans celebrated Saturnalia. Various cultures had a celebration on winter solstice, many of those tradions have become part of modern Christmas.
Mars has a different orbital period, and different length of day. I believe Martians will develop their own holidays.
]]>AD and CE are abbreviations used to refer to years, the term AD stands for Anno Domini, which means “in the year of our Lord” in Latin. Star of Bethlehem, or Christmas Star, appears in the nativity story of the Gospel of Matthew chapter 2 where "wise men from the East" or Magi are inspired by the star to travel to Jerusalem, they meet King Herod of Judea. As the West goes more Atheist and more secular BC was more commonly used it stands for Before Christ and now BCE stands for Before Common Era.
Experts suggest 'The Star of Bethlehem' was a real astronomical event
https://www.unilad.com/technology/space … -20231218/
Thought to have occurred around the year 85 CE, astronomers have since weighed in on the idea that the Star could have been a genuine astronomical event.
The Gospel was originally penned in Greek, and 'αστερα' was translated as 'astra' meaning star - but this can also refer to other celestial objects like a planet or comet.
Speaking of IFLScience on the matter, Dr Greg Brown, astronomer at the Royal Observatory Greenwich in London, said: "An unusual event like a supernova would certainly be a possible candidate with one having occurred in the year 4 BCE.
Jesus was born in June? Astronomers have made several attempts to link the star to unusual celestial events, such as a conjunction of Jupiter and Saturn or Jupiter and Venus, a comet, or a supernova.

Common Errors in "Star of Bethlehem" Planetarium Shows
https://web.archive.org/web/20080516043 … _xmas.html
Today the supposed nova of 6 B.C. is often forgotten and it is stated that Kepler identified the triple conjunction with the Star of Bethlehem. This incorrect statement dates to the early 19th century when Bishop Munter of Zealand, Denmark, who apparently did not know of Kepler's work or of the nova of 1604 independently suggested that the triple conjunction alone was the Star. He wrote that since the two planets were only one degree apart, weak eyes would have made them out as a single star-clearly a false impression. In a popular chronological handbook published a few years later, Ludwig Ideler, who did not know of Kepler, incorrectly attributed Munter's hypothesis to Kepler. Munter's book was widely read while Kepler's was not, and the error became entrenched in the literature.
When determining the date of the birth of Christ, Dionysious Exiguus forgot that Caesar Augustus had ruled under the name of Octavian for four years, and thus made a four-year error.
]]>just how many turkeys might we need for a mars colony to celebrate with.
How many pounds of turkey will the US Navy cook this Thanksgiving?
This year the Navy predicts CSs in their afloat galleys will prepare 85,195 pounds of roast turkey, 39,380 pounds of mashed potatoes, 23,650 pounds of stuffing, 17,600 pounds of sweet potatoes, 9,680 pounds of green bean casserole, 5,335 pounds of cranberry sauce, 3,960 gallons of gravy, and 8,635 assorted pies for sailors.
Baked ham, corn, and eggnog will also be on the menu.
The Navy’s more than 8,000 highly trained CSs play a critical role in sailor quality of life. An important part of any deployment, CSs prepare food that sustains warfighters whether they’re deployed ashore or afloat.

Best wishes to everyone for this Day, and for the (Earth) year ahead!
In my neighborhood, it is time to hang Christmas lights, so I'll be doing that later on.
This forum has a lot to be grateful for ... We are supported by the Mars Society, we have a Webmaster among the Admins, and work is progressing nicely in the long term direction of upgrading to current level software.
We have active members who come from a wide variety of backgrounds and a wide variety of interests, so the flow of messages is abundant, and it often stretches our ability to keep up. We have active projects under way with long term objectives, in addition to the one-time-only observations that are part of the archive.

]]>Your post about time keeping on the Moon inspired a search to see what NewMars members might have created as topics with the word "Time".... The list is longer than I expected, but none of the topics are about the issue of keeping time away from Earth.
It is (by now) well understood (by many folks but certainly not all) that time runs at different rates depending upon the strength of the local gratational field.
A topic about time keeping might fit nicely in the Science Index.
I'll hold off on creating one, on the chance you might like to do the honors. You are far more likely to find citations/references/examples on time keeping than most of the rest of the active membership. On the ** other ** hand, any of us may encounter a report involving time keeping away from Earth, so having a topic available would be helpful.
If you do decide to create a topic, please think about how to make it easy to find.

]]>'With multiple nations likely to have lunar bases & robotic craft on the Moon in the next decade, standards for lunar time & time zones will need to be created. One proposal is to use a decentralized approach very different from how time is kept across Earth.'

How Should Space Settlers Keep Track of Time?
https://slate.com/technology/2019/07/sp … endar.html
Our earthly system of years, months, and days doesn’t make much sense on Mars or the moon.
Individual settlements might evolve their own conventions according to local constraints. Gangale has adapted the Darian calendar for Jupiter’s moons Io, Ganymede, Callisto, and Europa, and Saturn’s moon Titan, which could be humanity’s next outposts beyond Mars. For settlers staying closer to home, nonprofit group LunarClock.org advocates for Lunar Standard Time and the Lunar Calendar, where a year consists of 12 “days” (comparable to Earth months), each named for a person who has walked on the moon, broken up into 30 “cycles” (comparable to Earth days) of 24 moon-hours.
The other challenge settlers will face in developing alternatives to Earth time is actually keeping the time. Time on Earth is standardized by incredibly stable atomic clocks, which drift by just one second every 15 billion years. Unfortunately, they’re the size of refrigerators. Spacecraft keep time on board using ultrastable oscillators, which allow spacecraft to plan and execute maneuvers, but “they’re not [really] ultrastable—they drift over time,” says Jill Seubert, deep space navigator at NASA. (I dare you to find a better job title than Seubert’s.) The first ultrastable oscillator, or USO, was used on the Voyager probes in the 1970s, and they’re still in satellites today. Even over the course of an Earth day, those satellites must be recalibrated to ensure technologies like GPS are as accurate as possible. Being off by just a millionth of a second can mean a GPS discrepancy of hundreds of meters.

]]>I'm not really religious but I do kind of understand why Australia marks Christian European or British events, but the recent stabbing of Rushdie got me thinking negatively about religion or a religion so I got annoyed to read about marking some islamic event at the Arctic or South Pole
Maybe an event happens and yet days get lost in the history of time keeping. The Egyptians and Roman and Chinese and Hindus and cultures of the Americans marked days with reasonable accuracy, a unisolar calendar the Babylonian calendar was a lunisolar calendar with years consisting of 12 lunar months, each beginning when a new crescent moon, the Gregorian calendar is the calendar used in most parts of the world introduced in October by Pope Gregory the 13th as a modification of, and replacement for, the Julian calendar
Astronomers have made several attempts to link the star to a celestial event maybe it happened and was a comet, or happening such as a conjunction of Jupiter and Saturn or Jupiter and Venus or some other event like supernova, there might even be religion ufology cult people who believe a UFO came to Earth long ago and little green men shone a torch out their UFO window to guide the men?

Martian Year: 36 Martian Month in 12 month format: 11 <<== The Astronomical month will increment when longitude reaches 330 degrees
Solar Longitude: 315.7 Sol Number: 589 Change in degrees is +.5 Julian date is: J0036589
Solar Longitude: 315.1 Sol Number: 588 Change in degrees is +.5 Julian date is: J0036588
Solar Longitude: 314.6 Sol Number: 587 Change in degrees is +.6 Julian date is: J0036587
---Note that Solar Longitude measurement varies as a function of location in orbit. Ls 0 is the moment when the Sun appears to transit from one hemisphere to the other. The transition itself is a function of the tilt of an object with respect to the Solar plane. Per squarewidget.com, Hipparchus created the celestial coordinate system we use today.

---Observation: The sky view is ** filled ** with objects and very few have been recorded and given identification by humans or their robot assistants
And! ** All ** the location assignments are from the perspective of Earth. The entire catalog needs to be adjusted when inter-stellar travel begins
The work that lies ahead for the astronomical community is daunting - there is work ahead for centuries
2022/01/19 - All current (existing) stellar catalogs are computed with reference to the Earth. Another civilization would use it's planet as reference.
Perhaps a Milky Way frame of reference will become necessary at some point. The Earth is as good a Zero point as any, for humans.As a general observation ... I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
In recent days, the curve has been holding steady , and on 2022/09/01, it is inclining upward at about 10 degrees---
Earth Distance 2022/10/05 113,356,298 (decrease)
Earth Distance 2022/10/04 114,263,888 (decrease)
Earth Distance 2022/10/03 115,088,308 (decrease)
---Mars and Earth are coming closer after Conjunction. The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.
Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Estimated light times: 1:18, 2:36, 3:54, 4:72, 5:90, 6:108, 7:126, 8:144, 9:162, 10:180, 11:198,12:216, 13:234, 14:252, 15:270, 16:288, 17:306
Light travel time today is between 6 and 7 minutes. Communications delay would be 12+ minutes round trip.In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth. Communications delays in that circumstance will increase due to the extra distance to be covered. Mr. Musk indicated he expects such communication will be handled by laser. Location would be optimum at poles of solar plane.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. <<== The current year on Mars is 36
Per www.planetary.org this occurred February 7, 2021 (on Earth). The new Mars Year is 36.The last Skip Day occurred September 3, 2022 on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected October 10, 2022 (range 9th >> 11th) on Earth. The next skip day will separate the week days.For those who may not 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
337 Earth days were observed to elapse in the 2020 weekday cycle. There were 7 week day transitions and 2 Quarter ends.
The next cycle began on the first Sol of the period of coincidence. The alignment of weekdays interval is in the range: (310 - 337)
