Today on Earth: 2025/12/06 Saturday Earth Date) Post Title: Today on Mars
====*====*==
To see how this calendar works, we show the standard 28 day month at the bottom of this daily report.
There are 20 months of 28 Sols and 4 months of 27 Sols at the end of the four six-month quarters.
New Years Eve is extended to align the Business Calendar for Mars with the Astronomical calendar.
Business and Astronomical both start at zero (to the nanosecond) on New Year's Day.
This calendar has been in operation for two full Mars years (36 and 37). We are in Year 38
Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for opposition/perigee/aphelion

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. Update from Mars.NASA.gov (The Sun crosses the equator of Mars (Vernal Equinox)). 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 some 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.

Zoom Out Capability 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 (Zoom out)
Update 2022/12/08 TheSkyLive.com provides a large view of selected objects: Select [Major Bodies] Then select [Information] in the body of interest
Update 2022/12/08 Scroll down to (body) Position and Finder Charts. Field of view is 50x30 degrees.
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:
1:18,2:36,3:54,4:72,5:90,6:108,7:126,8:144,9:162,10:180,11:198,12:216,13:234,14:252,15:270,16:288,17:306,18:324, 19:342,20:360,21:378,22:396
Light travel time today is between 20 and 21 minutes. Communications delay would be 40+ minutes round trip.

Earth Distance in km: 2025/12/06 362,527,076 (decreasing)
Earth Distance in km: 2025/12/05 362,550,825 (decreasing)
Earth Distance in km: 2025/12/04 362,570,481 (decreasing)
<<#
Maximum Earth-Mars distance is estimated to be 401 million kilometers (both at apogee and opposite vs Sun) Minimum is about 56 million kilometers
Mars and Earth were in Opposition (Earth center) in December of 2022. The date coincided with a (very rare) occultation of Mars by the Moon.
Mars and Earth were in Conjunction (Sun center) in November of 2023.
Mars and Earth appear to have been as close as they will get in Year 36. 81,454,323 kilometers on J0036644 Time: 4.53 minutes - 9 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. Year 38 started November 12, 2024 on Earth
Per www.planetary.org Year 36 started 2021/02/07 on Earth. Mars Year 37 began 2022/12/27 on Earth.
Days of the Week Alignment:
Days of the week fall behind Earth due to the longer Sol, but they also change 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)

Zoom Out Capability 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 (Zoom out)
Update 2022/12/08 TheSkyLive.com provides a large view of selected objects: Select [Major Bodies] Then select [Information] in the body of interest
Update 2022/12/08 Scroll down to (body) Position and Finder Charts. Field of view is 50x30 degrees.
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:
1:18,2:36,3:54,4:72,5:90,6:108,7:126,8:144,9:162,10:180,11:198,12:216,13:234,14:252,15:270,16:288,17:306,18:324, 19:342,20:360,21:378,22:396
Light travel time today is between 20 and 21 minutes. Communications delay would be 40+ minutes round trip.

Mars and Earth appear to have been as close as they will get in Year 36. 81,454,323 kilometers on J0036644 Time: 4.53 minutes - 9 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. Year 38 started November 12, 2024 on Earth
Per www.planetary.org Year 36 started 2021/02/07 on Earth. Mars Year 37 began 2022/12/27 on Earth.
Days of the Week Alignment:
Days of the week fall behind Earth due to the longer Sol, but they also change 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)

To see how this calendar works, we show the standard 28 day month at the bottom of this daily report.
There are 20 months of 28 Sols and 4 months of 27 Sols at the end of the four six-month quarters.
New Years Eve is extended to align the Business Calendar for Mars with the Astronomical calendar.
Business and Astronomical both start at zero (to the nanosecond) on New Year's Day.
This calendar has been in operation for two full Mars years (36 and 37). We are in Year 38

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. Update from Mars.NASA.gov (The Sun crosses the equator of Mars (Vernal Equinox)). 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.

Sol 382 is Friday in the Proposed Business calendar for Mars. Sol 376 was a Skip Day on Mars. Next is near 413 of Year 38
##
The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. Year 38 started November 12, 2024 on Earth
Per www.planetary.org Year 36 started 2021/02/07 on Earth. Mars Year 37 began 2022/12/27 on Earth.
Days of the Week Alignment:
Days of the week fall behind Earth due to the longer Sol, but they also change 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)
To find the first day of a period of coincidence: Set up: SearchTerm(colon) and (colon)Alignment and J0036* or J0037*

To see how this calendar works, we show the standard 28 day month at the bottom of this daily report.
There are 20 months of 28 Sols and 4 months of 27 Sols at the end of the four six-month quarters.
New Years Eve is extended to align the Business Calendar for Mars with the Astronomical calendar.
Business and Astronomical both start at zero (to the nanosecond) on New Year's Day.
This calendar has been in operation for two full Mars years (36 and 37). We are in Year 38

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. Update from Mars.NASA.gov (The Sun crosses the equator of Mars (Vernal Equinox)). 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.

Note#3: The computations below are dependent upon both the computations provided by the reference web site and by accuracy of recording of the time of observations. The calculations use tenths of hours. The Sun Distance needs to be captured at the moment the time increments to a given tenth.
Note on data below: The figure quoted after distance is a rate of progress along the orbital path [exact meaning to be determined]
Minus prefix means Mars is approaching the Sun. Plus prefix means Mars is moving away from the Sun.
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. Increasing to Aphelion/Decreasing to Perihelion.

Observation: The sky view is ** filled ** with objects and some 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.

Zoom Out Capability 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 (Zoom out)
Update 2022/12/08 TheSkyLive.com provides a large view of selected objects: Select [Major Bodies] Then select [Information] in the body of interest
Update 2022/12/08 Scroll down to (body) Position and Finder Charts. Field of view is 50x30 degrees.
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:
1:18,2:36,3:54,4:72,5:90,6:108,7:126,8:144,9:162,10:180,11:198,12:216,13:234,14:252,15:270,16:288,17:306,18:324, 19:342,20:360,21:378,22:396
Light travel time today is between 20 and 21 minutes. Communications delay would be 40+ minutes round trip.

Maximum Earth-Mars distance is estimated to be 401 million kilometers (both at apogee and opposite vs Sun) Minimum is about 56 million kilometers
Mars and Earth were in Opposition (Earth center) in December of 2022. The date coincided with a (very rare) occultation of Mars by the Moon.
Mars and Earth were in Conjunction (Sun center) in November of 2023.
Mars and Earth appear to have been as close as they will get in Year 36. 81,454,323 kilometers on J0036644 Time: 4.53 minutes - 9 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.

To see how this calendar works, we show the standard 28 day month at the bottom of this daily report.
There are 20 months of 28 Sols and 4 months of 27 Sols at the end of the four six-month quarters.
New Years Eve is extended to align the Business Calendar for Mars with the Astronomical calendar.
Business and Astronomical both start at zero (to the nanosecond) on New Year's Day.
This calendar has been in operation for two full Mars years (36 and 37). We are in Year 38

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. Update from Mars.NASA.gov (The Sun crosses the equator of Mars (Vernal Equinox)). The transition itself is a function of the tilt of an object with respect to the Solar plane.

Observation: The sky view is ** filled ** with objects and some 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.

Zoom Out Capability 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 (Zoom out)
Update 2022/12/08 TheSkyLive.com provides a large view of selected objects: Select [Major Bodies] Then select [Information] in the body of interest
Update 2022/12/08 Scroll down to (body) Position and Finder Charts. Field of view is 50x30 degrees.
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:
1:18,2:36,3:54,4:72,5:90,6:108,7:126,8:144,9:162,10:180,11:198,12:216,13:234,14:252,15:270,16:288,17:306,18:324, 19:342,20:360,21:378,22:396
Light travel time today is between 20 and 21 minutes. Communications delay would be 40+ minutes round trip.

Maximum Earth-Mars distance is estimated to be 401 million kilometers (both at apogee and opposite vs Sun) Minimum is about 56 million kilometers
Mars and Earth were in Opposition (Earth center) in December of 2022. The date coincided with a (very rare) occultation of Mars by the Moon.
Mars and Earth were in Conjunction (Sun center) in November of 2023.
Mars and Earth appear to have been as close as they will get in Year 36. 81,454,323 kilometers on J0036644 Time: 4.53 minutes - 9 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. Year 38 started November 12, 2024 on Earth
Per www.planetary.org Year 36 started 2021/02/07 on Earth. Mars Year 37 began 2022/12/27 on Earth.
Days of the Week Alignment:
Days of the week fall behind Earth due to the longer Sol, but they also change 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)

Observation: The sky view is ** filled ** with objects and some 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.
=== Mars is in Regular movement as seen from Earth.
Next ahead: TYC 6842-1054-1 RA 18h 00m 52.3s in path on Day 0 ahead
TYC 6841-1761-1 RA 17h 58m 12.2s Day 0 ahead in path Day 1 at 8 hours past marker

Zoom Out Capability 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 (Zoom out)
Update 2022/12/08 TheSkyLive.com provides a large view of selected objects: Select [Major Bodies] Then select [Information] in the body of interest
Update 2022/12/08 Scroll down to (body) Position and Finder Charts. Field of view is 50x30 degrees.
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:
1:18,2:36,3:54,4:72,5:90,6:108,7:126,8:144,9:162,10:180,11:198,12:216,13:234,14:252,15:270,16:288,17:306,18:324, 19:342,20:360,21:378,22:396
Light travel time today is between 20 and 21 minutes. Communications delay would be 40+ minutes round trip.

Maximum Earth-Mars distance is estimated to be 401 million kilometers (both at apogee and opposite vs Sun) Minimum is about 56 million kilometers
Mars and Earth were in Opposition (Earth center) in December of 2022. The date coincided with a (very rare) occultation of Mars by the Moon.
Mars and Earth were in Conjunction (Sun center) in November of 2023.
Mars and Earth appear to have been as close as they will get in Year 36. 81,454,323 kilometers on J0036644 Time: 4.53 minutes - 9 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.

Sol 387 is Wednesday in the Proposed Business calendar for Mars. Sol 376 was a Skip Day on Mars. Next is near 413 of Year 38
##
The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. Year 38 started November 12, 2024 on Earth
Per www.planetary.org Year 36 started 2021/02/07 on Earth. Mars Year 37 began 2022/12/27 on Earth.
Days of the Week Alignment:
Days of the week fall behind Earth due to the longer Sol, but they also change 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)
To find the first day of a period of coincidence: Set up: SearchTerm(colon) and (colon)Alignment and J0036* or J0037*
The most recent End-Of-Quarter change occurred: … The search specified above gave 11 pages of results.
