Today on Earth: 2021/12/11 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
Martian Year: 36 Martian Month in 12 month format: 5 <<== The Astronomical month will increment when longitude reaches 150 degrees
Solar Longitude: 139.9 Sol Number: 299 Change in degrees is +.5
Previous SL: 139.4 Previous Sol:298
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.
Distance: Mars >> Sun per theskylive.com: 233,724,643 km [23.5 km/s] Difference is -190009 <= 7600 km/hour at 8.0 on 12/11 (time:8:00)
Distance: Mars >> Sun per theskylive.com: 233,914,652 km [23.5 km/s] Difference is -174174 <= 7573 km/hour at 7.0 on 12/10 (time:7:00)
Distance: Mars >> Sun per theskylive.com: 234,088,826 km [23.5 km/s] Difference is -181127 <= 7547 km/hour at 8.0 on 12/09 (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
Next up: a pair in line below path: TYC 6194-1088-1 Mg 11.22 TYC 6194-895-1 Mg 12.30 Day 0 about 18 hours ahead
TYC 6193-1486-1 Magnitude 10.77 just below path and about 10 hours ahead on Day 0 - Day 1 out of view
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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.
Earth Distance 2021/12/11 365,178,285 (decrease)
Earth Distance 2021/12/10 365,849,701 (decrease)
Earth Distance 2021/12/09 366,512,069 (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 20 and 21 minutes. Communications delay would be 40+ minutes round trip. [20:360,000,000][21:390,000,000]
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

Month 11 extends from Sol 280 through 307. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 09

Sol 299 is Friday in the Proposed Business calendar for Mars.
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 December (estimate: 15th) 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.

Martian Year: 36 Martian Month in 12 month format: 5 <<== The Astronomical month will increment when longitude reaches 150 degrees
Solar Longitude: 141.9 Sol Number: 302 Change in degrees is +.5
Previous SL: 141.4 Previous Sol:302 <<== Skip Day
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.
Distance: Mars >> Sun per theskylive.com: 232,985,261 km [23.6 km/s] Difference is -184743 <= 7698 km/hour at 8.5 on 12/15 (time 8:30)
Distance: Mars >> Sun per theskylive.com: 233,170,004 km [23.6 km/s] Difference is -183482 <= 7677 km/hour at 8.5 on 12/14 (time 8:30)
Distance: Mars >> Sun per theskylive.com: 233,353,486 km [23.6 km/s] Difference is -195816 <= 7649 km/hour at 8.6 on 12/13 (time 8:36)
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
Next up: Galaxy below path ESO 583-9 Magnitude 15.40 RA 15h 58m 20.2s about 15 hours ahead on Day 0
TYC 6195-776-1 Mg 10.05 and TYC 6195-725-1 Mg 9.33 Day 0 about 12 hours ahead - Day 1 Still in view but just barely. More than 9 hours past
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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.
Earth Distance 2021/12/15 362,394,351 (decrease)
Earth Distance 2021/12/14 363,114,048 (decrease)
Earth Distance 2021/12/13 363,806,924 (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 20 and 21 minutes. Communications delay would be 40+ minutes round trip. [20:360,000,000][21:390,000,000]
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

Sol 302 is Monday in the Proposed Business calendar for Mars.
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 January 2022 (estimate: 21st) 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.

Martian Year: 36 Martian Month in 12 month format: 5 <<== The Astronomical month will increment when longitude reaches 150 degrees
Solar Longitude: 143.9 Sol Number: 306 Change in degrees is +.5
Previous SL: 143.4 Previous Sol:305
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.
Distance: Mars >> Sun per theskylive.com: 232,244,862 km [23.7 km/s] Difference is -186858 <= 7786 km/hour at 8.0 on 12/19 (time 8:00)
Distance: Mars >> Sun per theskylive.com: 232,432,720 km [23.7 km/s] Difference is -194103 <= 7764 km/hour at 8.0 on 12/18 (time 8:00)
Distance: Mars >> Sun per theskylive.com: 232,625,823 km [23.6 km/s] Difference is -178076 <= 7742 km/hour at 7.0 on 12/17 (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
Next up: TYC 6213-1385-1 Magnitude 11.48 just below path Day 0 about 15 hours ahead
TYC 6212-189-1 Magnitude 10.84 below path and about 9 hours ahead on Day 0 - Day 1 about 12 hours past Mars
Note new Boomer above and past Mars: HIP 78990 Magnitude 4.24 RA 16h 07m 7.2s
Note Boomer on the scene today! HIP 78933 Magnitude 3.95 above and ahead of Mars - Still visible on Day 1 at top of view
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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.
Earth Distance 2021/12/19 359,590,355 (decrease) << Dropped below 360,000,000
Earth Distance 2021/12/18 360,275,073 (decrease) << Close to 360,000,000 Time for Travel Update
Earth Distance 2021/12/17 361,033,498 (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 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:330,000,000/20:360,000,000]
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

Month 11 extends from Sol 280 through 307. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 09

Sol 306 is Friday in the Proposed Business calendar for Mars.
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 January 2022 (estimate: 21st) 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.

Today on Earth: 2021/12/23 Thursday (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
Martian Year: 36 Martian Month in 12 month format: 5 <<== The Astronomical month will increment when longitude reaches 150 degrees
Solar Longitude: 145.9 Sol Number: 310 Change in degrees is +.5
Previous SL: 145.4 Previous Sol:309
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.
Distance: Mars >> Sun per theskylive.com: 231,492,560 km [23.8 km/s] Difference is -188738 <= 7864 km/hour at 8.0 on 12/23 (time 8:00)
Distance: Mars >> Sun per theskylive.com: 231,681,298 km [23.7 km/s] Difference is -188323 <= 7847 km/hour at 8.0 on 12/22 (time 8:00)
Distance: Mars >> Sun per theskylive.com: 231,869,621 km [23.7 km/s] Difference is -187873 <= 7828 km/hour at 8.0 on 12/21 (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
Next up: Galaxy in path: PGC 826640 RA 16h 21m 21.8s Day 0 about 12 hours ahead
HIP 79910 Magnitude 8.95 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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.
Earth Distance 2021/12/23 356,670,443 (decrease)
Earth Distance 2021/12/22 357,406,902 (decrease)
Earth Distance 2021/12/21 358,125,974 (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 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:330,000,000/20:360,000,000]
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.

Sol 310 is Tuesday in the Proposed Business calendar for Mars.
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 January 2022 (estimate: 21st) 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.

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.
Distance: Mars >> Sun per theskylive.com: 230,733,060 km [23.8 km/s] Difference is -190580 <= 7940 km/hour at 8.0 on 12/27 (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

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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.

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 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:330,000,000/20:360,000,000]
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.

Per www.planetary.org this occurred February 7, 2021 (on Earth). The new Mars Year is 36.
The next Skip Day will occur in January 2022 (estimate: 21st) 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.

Observation: The sky view is ** filled ** with objects and very few have been recorded and given identification by humans or their robot assistants

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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.

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 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:330,000,000/20:360,000,000]
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.

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 January 2022 (estimate: 21st) 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.

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.
Distance: Mars >> Sun per theskylive.com: 229,192,724 km [24.0 km/s] Difference is -185106 <= 8048 km/hour at 8.5 on 01/04 (time 8:30)
Distance: Mars >> Sun per theskylive.com: 229,377,830 km [24.0 km/s] Difference is -204846 <= 8033 km/hour at 9.5 on 01/03 (time 9:30)
Distance: Mars >> Sun per theskylive.com: 229,582,676 km [24.0 km/s] Difference is -192663 <= 8028 km/hour at 8.0 on 01/02 (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
Next up: a flattened triangle: TYC 6810-239-1 Mg 11.49 RA 15h 57m 22.6s trailed by 6810-275-1 and 6810-72-1 below path about 9 hours ahead
Note that the path angle is gradually rising from descending towards horizontal
A pair in path: TYC 6810-94-1 Mg 11.39 TYC 6810-107-1 Mg 11.77 Day 0 about 18 hours ahead
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.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.
Earth Distance 2022/01/04 347,375,889 (decrease)
Earth Distance 2022/01/03 348,161,725 (decrease)
Earth Distance 2022/01/02 348,999,933 (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 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:330,000,000/20:360,000,000]
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
This web site offers an online model of the solar system: www.solarsystemscope.com It requires Chrome 57, Firefox 52 or Safari 10.1
Sol 322 is in Month 12 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 12 extends from Sol 308 through 334. See post 82 of Holidays topic for current details. <<== There are 27 days in Month 12

Sol 322 is Sunday in the Proposed Business calendar for Mars.
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 January 2022 (estimate: 21st) 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.
