Today on Earth: 2022/04/12 Tuesday (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: 207.0 Sol Number: 417 Change in degrees is +.6
Previous SL: 206.4 Previous Sol:416
---
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: 211,664,954 km [25.9 km/s] Difference is -136065 <= -5669 km/hour at 8.0 on 04/12 (time 8:00)
Distance: Mars >> Sun per theskylive.com: 211,801,019 km [25.9 km/s] Difference is -137573 <= -5732 km/hour at 8.0 on 04/11 (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.

As a general observation ... I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
In recent days, the curve has been slowly bending up , and on 2022/04/11, it is inclining upward at about 10 degrees
Earth Distance 2022/04/12 259,742,069 (decrease)
Earth Distance 2022/04/11 260,650,555 (decrease)
Earth Distance 2022/04/10 261,478,666 (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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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

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 April 2022 (on:6th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in May 2022 (on 13th) 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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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

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 April 2022 (on:6th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in May 2022 (on 13th) 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.

Observation: The sky view is ** filled ** with objects and very few have been recorded and given identification by humans or their robot assistants
And! ** All ** the location assignments are from the perspective of Earth. The entire catalog needs to be adjusted when inter-stellar travel begins
The work that lies ahead for the astronomical community is daunting - there is work ahead for centuries
2022/01/19 - All current (existing) stellar catalogs are computed with reference to the Earth. Another civilization would use it's planet as reference.
Perhaps a Milky Way frame of reference will become necessary at some point. The Earth is as good a Zero point as any, for humans.

As a general observation ... I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.

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
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: Galaxy above path: PGC 964800 RA 22h 23m 41.5s Day 0 about 15 hours ahead
TYC 5807-423-1 Mg 9.69 RA 22h 20m 17.1s Day 0 - about 9 hours ahead Day 1 still visible in the extreme lower right corner of the 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.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
In recent days, the curve has been slowly bending up , and on 2022/04/11, it is inclining upward at about 10 degrees
Earth Distance 2022/04/19 253,604,444 (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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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

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: Two galaxies across path: Top: PGC 974801 RA 22h 32m 07.4s Day 0 about 15 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.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
In recent days, the curve has been slowly bending up , and on 2022/04/11, it is inclining upward at about 10 degrees
Earth Distance 2022/04/22 250,999,999 (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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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

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 April 2022 (on:6th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in May 2022 (on 13th) 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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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 430 is Thursday in the Proposed Business calendar for Mars. Sol 411 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 April 2022 (on:6th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in May 2022 (on 13th) 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.

On Day Note: Per SpaceNut suggestion in Post #1414, this would be Julian day 0036430 on Mars.
We might drop the 2 lead zeros if we do not thing we will need them to shorten the display digit count.
Nice thou I was way off. Its one way to do schedules that make sense when we need to know where we are in a process. It also gives the means to do a count down once you set the first parameter for when the process starts.
We will use lots of different calendars to be able to keep work and other activities making sense as we adjust to mars time.

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 a rate of progress along path [exact meaning to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. Increasing to Aphelion/Decreasing to Perihelion.
Distance: Mars >> Sun per theskylive.com: 209,923,959 km [26.1 km/s] Difference is -113711 <= -4738 km/hour at 8.0 on 04/26 (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: An unlabeled asterism across the path: RA 22h 43m 10.5s about 10 hours ahead on Day 1
Next up: There are plenty of stars but none are marked. Dry hole! First time this has happened since this daily procedure started.
PGC 932380 RA 22h 40m 38.3s - Day 0 about 9 hours ahead - Day 1 still visible just above the bottom of the view - about 16 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 upward and East as seen from Earth
In recent days, the curve has been slowly bending up , and on 2022/04/11, it is inclining upward at about 10 degrees

Sol 433 is Sunday in the Proposed Business calendar for Mars. Sol 411 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 April 2022 (on:6th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in May 2022 (on 13th) 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.

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 a rate of progress along the orbital path [exact meaning to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. Increasing to Aphelion/Decreasing to Perihelion.
Distance: Mars >> Sun per theskylive.com: 209,593,191 km [26.2 km/s] Difference is -108459 <= -4519 km/hour at 8.0 on 04/29 (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.

As a general observation ... I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
In recent days, the curve has been slowly bending up , and on 2022/04/11, it is inclining upward at about 10 degrees
Earth Distance 2022/04/29 244,936,666 (decrease)
Earth Distance 2022/04/28 245,730,000 (decrease)
Earth Distance 2022/04/27 246,678,888 (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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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

Martian Year: 36 Martian Month in 12 month format: 8 <<== The Astronomical month will increment when longitude reaches 240 degrees
Solar Longitude: 219.3 Sol Number: 437 Change in degrees is +.6 Julian date is: 0036437
Solar Longitude: 218.7 Sol Number: 436 Change in degrees is +.7 Julian date is: 0036436
---
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 a rate of progress along the orbital path [exact meaning to be determined]
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. Increasing to Aphelion/Decreasing to Perihelion.
Distance: Mars >> Sun per theskylive.com: 209,269,319 km [26.2 km/s] Difference is -112130 <= -4296 km/hour at 10.1 on 05/02 (time 10:06)
Distance: Mars >> Sun per theskylive.com: 209,381,449 km [26.2 km/s] Difference is -104996 <= -4374 km/hour at 8.0 on 05/01 (time 8:00)
Distance: Mars >> Sun per theskylive.com: 209,486,445 km [26.2 km/s] Difference is -106746 <= -4448 km/hour at 8.0 on 04/30 (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 pair of galaxies in the path and about 15 hours ahead on Day 0: PGC 1010414 and PGC 1010348 RA 23h 01m 08.8s
Next up: Galaxy below path: PGC 1007429 RA 23h 01m 10.8s Day 0 about 10 hours ahead -
star in minor asterism at RA 22h 57m 48.8s about 10 hours ahead on Day 0 just below path - Day 1 still visible in lower right 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.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature. If anyone knows of such a service, please contact the NewMars portal.
Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
In recent days, the curve has been slowly bending up , and on 2022/04/11, it is inclining upward at about 10 degrees
Earth Distance 2022/05/02 242,295,666 (decrease)
Earth Distance 2022/05/01 243,182,154 (decrease)
Earth Distance 2022/04/30 244,095,333 (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 16 and 17 minutes. Communications delay would be 32+ minutes round trip. [16:240,000,000/17:270,000,000]
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 437 is in Month 16 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary. <<== Skip Day Sol 411
Month 16 extends from Sol 919 through 446. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 15

Sol 437 is Thursday in the Proposed Business calendar for Mars. Sol 411 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 April 2022 (on:6th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in May 2022 (on 13th) 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 itself is showing location of: RA 23h 04m 54.1s In the next 24 hours of Earth time, Mars will advance through 23h 7m 13.3s to: ?
Thinking out loud here: if an orbit is 668 Earth Days, then each Earth day Mars should advance 360/668 degrees, or .5389. The actual rate varies (ellipse)
However, Earth is moving simultaneously, so where Mars appears against the celestial background will vary over the Mars year.
