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

Today on Mars: 0036/14/09 Monday <<-- Days of the week offset 2 with Earth.

Today on Earth: 2022/02/23 Wednesday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for oppositon/perigee/aphelion

Martian Year: 36  Martian Month in 12 month format: 6 <<== The Astronomical month will increment when longitude reaches 180 degrees

Solar Longitude: 179.0 Sol Number: 371  Change in degrees is +.6
Previous SL:      178.4 Previous Sol:370

Note that Solar Longitude measurement varies as a function of location in orbit. 

Note#2: https://theskylive.com/mars-tracker  This web site shows the astronomical position of Mars.
Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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 [to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. That distance should be increasing to Aphelion.

Distance: Mars >> Sun per theskylive.com:   219,533,481 km [25.0 km/s] Difference is -190761 <= -7754 km/hour at 8.6 on 02/23 (time 8:36)
Distance: Mars >> Sun per theskylive.com:   219,724,242 km [25.0 km/s] Difference is -186665 <= -7778 km/hour at 8.0 on 02/22 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   219,910,907 km [25.0 km/s] Difference is -187194 <= -7800 km/hour at 8.0 on 02/21 (time 8:00)

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.

Next up: Just above path: TYC 6311-42-1 Mg 10.20 RA 19h 36m 25.7s Day 0 about 14 hours ahead
PGC 813938 RA 19h 33m 43.2s Day 0 about 15 hours ahead - Day 1 in path - right at the 8 hour marker [8+15>>23(actual 24.6)]

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/02/23 303,483,371 (decrease)
Earth Distance 2022/02/22 304,438,680 (decrease)
Earth Distance 2022/02/21 305,360,881 (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.
Light travel time today is between 18 and 19 minutes. Communications delay would be 36+ minutes round trip. [18:300,000,000/19:330,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

Sol 371 is in Month 14 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month  14 extends from Sol 363 through 390. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 14
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 371 is Monday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

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 next Skip Day will occur in February 2022 (estimate: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

TYC 6311-328-1 Mg 11.49 RA 19h 42m 05.9s - Day 0 about 12 hours ahead - Day 1 about 13 hours behind Mars.

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/02/26 300,738,550 (decrease)
Earth Distance 2022/02/25 301,742,225 (decrease)
Earth Distance 2022/02/24 302,625,682 (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.
Light travel time today is between 18 and 19 minutes. Communications delay would be 36+ minutes round trip. [18:300,000,000/19:330,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 374 is Thursday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

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 next Skip Day will occur in February 2022 (estimate: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

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

Today on Mars: 0036/14/13 Friday <<-- Days of the week offset 2 with Earth.

Today on Earth: 2022/02/27 Sunday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for oppositon/perigee/aphelion

Martian Year: 36  Martian Month in 12 month format: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 181.3 Sol Number: 375  Change in degrees is +.6
Previous SL:      180.7 Previous Sol:374

Note that Solar Longitude measurement varies as a function of location in orbit. 

Note#2: https://theskylive.com/mars-tracker  This web site shows the astronomical position of Mars.
Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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 [to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. That distance should be increasing to Aphelion.

Distance: Mars >> Sun per theskylive.com:   218,807,380 km [25.1 km/s] Difference is -175342 <= -7657 km/hour at 7.0 on 02/27 (time 7:01)
Distance: Mars >> Sun per theskylive.com:   218,982,722 km [25.1 km/s] Difference is -192710 <= -7678 km/hour at 8.1 on 02/26 (time 8:06)
Distance: Mars >> Sun per theskylive.com:   219,175,432 km [25.1 km/s] Difference is -177099 <= -7699 km/hour at 7.0 on 02/25 (time 7:00)

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.

Next up: A stack of three galaxies: PGC 823312/822568/822155 RA 19h 49m 03.7s Day 0 about 15 hours ahead

Per www.planetary.org this occurred February 7, 2021 (on Earth). The new Mars Year is 36.

The next Skip Day occurred in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

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

Today on Mars: 0036/14/15 Sunday <<-- Days of the week offset 3 with Earth. 

Today on Earth: 2022/03/02 Wednesday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for oppositon/perigee/aphelion

Martian Year: 36  Martian Month in 12 month format: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 183.0 Sol Number: 377  Change in degrees is +.6
Previous SL:      182.4 Previous Sol:376

Note that Solar Longitude measurement varies as a function of location in orbit. 

Note#2: https://theskylive.com/mars-tracker  This web site shows the astronomical position of Mars.
Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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 [to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. That distance should be increasing to Aphelion.

Distance: Mars >> Sun per theskylive.com:   218,245,650 km [25.2 km/s] Difference is -189081 <= -7563 km/hour at 9.0 on 03/02 (time 9:00)
Distance: Mars >> Sun per theskylive.com:   218,434,721 km [25.2 km/s] Difference is -181476 <= -7593 km/hour at 8.0 on 03/01 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   218,616,207 km [25.1 km/s] Difference is -191173 <= -7616 km/hour at 8.1 on 02/28 (time 8:06)

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.

Next up: TYC 6325-1020-1 Mg 11.29 RA 19h 58m 42.6s Day 0 below path about 12 hours ahead
TYC 6325-1231-1 RA 19h 56m 03.8s Mg 11.44 Day 0 just above path about 18 hours ahead - Day 1 about 5 hours past Mars

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/02 297,032,579 (decrease)
Earth Distance 2022/03/01 297,920,598 (decrease)
Earth Distance 2022/02/28 298,832,800 (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.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

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

For Clark re #1359 - Your kind words were a complete surprise!  My encounters with your 20 years ago posts reveal you were willing to invest in the members of the time.  This project is nothing more grand than a Tortoise vs Hare competition.  It is a bet that simplicity combined with persistence will yield a consensus.
I will admit that the simplicity comes from the (then fevered) brow of RobertDyck, who has gone on to lead the Large Ship enterprise. With modest talent, I am content to do book keeping for those with talent.  However, I'll admit that the productivity of GW Johnson often has me gasping to keep up. (th)

Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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 [to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. That distance should be increasing to Aphelion.

Distance: Mars >> Sun per theskylive.com:   217,713,130 km [25.2 km/s] Difference is -186742 <= -7470 km/hour at 8.0 on 03/05 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   217,899,872 km [25.2 km/s] Difference is -172555 <= -7502 km/hour at 7.0 on 03/04 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   218,072,427 km [25.2 km/s] Difference is -173223 <= -7531 km/hour at 8.0 on 03/03 (time 8:00)

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.

Next up ... a well formed galaxy seen from above: ESO 595-14 Mg 13.50 RA 20h 07m 37.8 s Day 0 about 12 hours ahead
HIP 98896 Mg 7.03 RA 20h 04m 58.0s below path Day 0 about 15 hours ahead - Day 1 - About 9 hours behind

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/05 294,268,888 (decrease)
Earth Distance 2022/03/04 295,218,613 (decrease)
Earth Distance 2022/03/03 296,167,214 (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.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

Month  14 extends from Sol 363 through 390. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 14
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 380 is Wednesday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

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 in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

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.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

Sol 383 is Saturday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

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 in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

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

Today on Mars: 0036/14/22 Sunday <<-- Days of the week offset 3 with Earth. 

Today on Earth: 2022/03/09 Wednesday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for oppositon/perigee/aphelion

Martian Year: 36  Martian Month in 12 month format: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 187.0 Sol Number: 384  Change in degrees is +.6
Previous SL:      186.4 Previous Sol:383

Note that Solar Longitude measurement varies as a function of location in orbit. 

Note#2: https://theskylive.com/mars-tracker  This web site shows the astronomical position of Mars.
Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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 [to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. That distance should be increasing to Aphelion.

Distance: Mars >> Sun per theskylive.com:   217,004,166 km [25.3 km/s] Difference is -175985 <= -7333 km/hour at 8.0 on 03/09 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   217,180,151 km [25.3 km/s] Difference is -176093 <= -7368 km/hour at 8.0 on 03/08 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   217,356,244 km [25.3 km/s] Difference is -185770 <= -7401 km/hour at 8.1 on 03/07 (time 8:06)

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.

Next up: TYC 6336-1635-1 Mg 12.20 RA 20h 19m 57.8s just above path Day 0 - about 10 hours ahead
TYC 6340-567-1 Mg 11.17 RA 20h 17m 20.1s well below path Day 0 about 12 hours ahead - Day 1 about 12 hours past Mars

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/09 290,604,666 (decrease)
Earth Distance 2022/03/08 291,530,664 (decrease)
Earth Distance 2022/03/07 292,462,444 (decrease)

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

Today on Mars: 0036/14/25 Wednesday <<-- Days of the week offset 3 with Earth. 

Today on Earth: 2022/03/12 Saturday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for oppositon/perigee/aphelion

Martian Year: 36  Martian Month in 12 month format: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 188.7 Sol Number: 387  Change in degrees is +.6
Previous SL:      188.1 Previous Sol:386

Note that Solar Longitude measurement varies as a function of location in orbit. 

Note#2: https://theskylive.com/mars-tracker  This web site shows the astronomical position of Mars.
Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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 [to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. That distance should be increasing to Aphelion.

Distance: Mars >> Sun per theskylive.com:   216,661,999 km [25.4 km/s] Difference is -173350 <= -7223 km/hour at 7.0 on 03/12 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   216,661,999 km [25.4 km/s] Difference is -167021 <= -7262 km/hour at 7.0 on 03/11 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   216,829,020 km [25.3 km/s] Difference is -175146 <= -7298 km/hour at 8.0 on 03/10 (time 8:00)

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.

Next up: Star in path and three galaxies: TYC 6337-1395-1 Mg 11.92 RA 20h 29m 22.3s PGC 847276 Day 1 about 9 hours ahead
PGC 842494 RA 20h 26m 35.9s TYC 6337-83-1 Mg 11.46 below path Day 0 about 12 hours ahead - Day 1 about 12 hours behind

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/12 287,882,882 (decrease)
Earth Distance 2022/03/11 288,804,777 (decrease)
Earth Distance 2022/03/10 289,610,555 (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.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

Sol 387 is in Month 14 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month  14 extends from Sol 363 through 390. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 14
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 387 is Wednesday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

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 in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

Distance: Mars >> Sun per theskylive.com:   215,967,039 km [25.4 km/s] Difference is -177568 <= -7103 km/hour at 9.0 on 03/15 (time 9:00)
Distance: Mars >> Sun per theskylive.com:   216,144,607 km [25.4 km/s] Difference is -171596 <= -7150 km/hour at 8.0 on 03/14 (time 8:00)
Note that Daylight Savings Time took effect in the US ... the time used for the computations for 03/13 reflects standard time.
Distance: Mars >> Sun per theskylive.com:   216,316,203 km [25.4 km/s] Difference is -172446 <= -7185 km/hour at 7.0 on 03/13 (time 7:00)

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.

Next up: A bracket pair: TYC 6338-1245-1 Mg 10.51 above TYC 6338-1233-1 below RA 20h 39m 45.8s about 15 hours ahead on Day 0
TYC 8338-1511-1 Mg 10.83 RA 20h 35m 49.5s - Day 0 about 12 hours ahead - Day 1 just barely still in view at far right - about 12 hours behind

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 slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/15 285,055,000 (decrease)
Earth Distance 2022/03/14 286,000,000 (decrease)
Earth Distance 2022/03/13 286,937,355 (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.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

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.

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.
Progress of Mars (as seen from Earth) is transitioning back to Eastward as the retrograde movement continues.
The online solar system display at the link below shows clearly how the Mars retrograde movement will occur in months ahead.
Retrograde movement started 2020/09/08 Sol 520 - Update 2022/01/04 Retrograde movement is still in progress on sol 322

Month  14 extends from Sol 363 through 390. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 14
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 390 is Saturday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

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 in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
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)
Use Search Term Alignment to find the first day of a period of coincidence.

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html also see: in-the-sky.org for oppositon/perigee/aphelion

Martian Year: 36  Martian Month in 12 month format: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 191.0 Sol Number: 391  Change in degrees is +.6
Previous SL:      190.4 Previous Sol:390

Note that Solar Longitude measurement varies as a function of location in orbit. 

Note#2: https://theskylive.com/mars-tracker  This web site shows the astronomical position of Mars.
Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion occurred on Sol 152 at 71 degrees Ls.
Aphelion occurred near 70 degrees Ls on Sol 153 (per www.planetary.org)

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.
