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

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

Today on Earth: 2022/01/31 Monday (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: 166.3 Sol Number: 348  Change in degrees is +.5
Previous SL:      165.8 Previous Sol:347

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:   223,932,294 km [24.6 km/s] Difference is -194768 <= -8115 km/hour at 8.0 on 01/31 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   224,127,062 km [24.5 km/s] Difference is -198950 <= -8120 km/hour at 8.0 on 01/30 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   224,326,012 km [24.5 km/s] Difference is -191024 <= -8129 km/hour at 7.5 on 01/29 (time 7:30)

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 6844-609-1 Mg 10.74 RA 18h 22m 15.9s in path Day 0 about 9 hours ahead
TYC 6844-1889-1 Mg 10.85 RA 18h 19m 22.4s just above path Day 0 about 10 hours ahead - day 1 about 14 hours behind Mars
The view is dense with stars. I'm guessing this must be a part of the Milky Way.
I marvel at the skill of astronomers (or their automated instruments) to identify specific stars in a field as dense as this.

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 2022/01/31 324,442,759 (decrease)
Earth Distance 2022/01/30 325,330,755 (decrease)
Earth Distance 2022/01/29 326,236,696 (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 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 348 is in Month 13 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month  13 extends from Sol 335 through 362. See post 82 of Holidays topic for current details. <<== There are 27 days in Month 12
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 348 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 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.

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 TYC 6857-850-1 Mg 12.15 RA 18h 32m 10.9s in path Day 0 about 10 hours ahead
Galaxy below path PGC 206456 RA 18h 29m 4.7s Day 0 about 12 hours ahead - Day 1 about 12 hours behind
The view is dense with stars. I'm guessing this must be a part of the Milky Way. Constellation is Sagittarius
I marvel at the skill of astronomers (or their automated instruments) to identify specific stars in a field as dense as this.

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 2022/02/03 321,733,912 (decrease)
Earth Distance 2022/02/02 322,661,112 (decrease)
Earth Distance 2022/02/01 323,567,118 (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 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 351 is Tuesday  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)

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

The progression of Mars across the starscape is shown by theskylive.com.

For most days, the view is populated with stars and occasionally galaxies.

Occasionally an unusual object joins Mars briefly, such as Mercury and even the Sun, although the Sun was well below the Mars view.

However, in today's view, and for the next day or so, we have a globular cluster to enliven the scene.

here is a snippet from an astronomical site:

Mars meets up with M22
On Feb. 5, Mars comes close to the globular cluster M22. You can catch them together in binoculars. This shot shows a different close approach, which occurred in November 2014.

Light travel time today is between 19 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.

Sol 354 is Friday  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)

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

One thing that we are learning is that the orbits of earth and of mars travel is something that even orbital mechanics will needs slight course corrections to occur when we travel to mars in the future with a large ship whether its a Starship or orbit to orbit large transport.
Knowing the distance before the projected launch aids in making the mission with a lot more successful in the long run for the landing on mars.

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

Today on Mars: 0036/13/21 Saturday <<-- Days of the week offset 2 with Earth.

Today on Earth: 2022/02/07 Monday (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: 170.1 Sol Number: 355  Change in degrees is +.5
Previous SL:      169.6 Previous Sol:354

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:   222,574,965 km [24.7 km/s] Difference is -201163 <= -8046 km/hour at 8.0 on 02/07 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   222,776,128 km [24.7 km/s] Difference is -191038 <= -8061 km/hour at 7.0 on 02/06 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   222,967,166 km [24.7 km/s] Difference is -196137 <= -8071 km/hour at 7.3 on 02/05 (time 7:18)

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 TYC 6850-842-1 Mg 9.46 RA 18h 45m 55.6s just below path - Day 0 about 18 hours ahead
HIP 91689 Mg 6.19 below path Day 0 - about 14 hours ahead - Day 1 in far lower right corner of view - About 11 hours behind Mars
TYC 6858-1417-1 Mg 9.72 RA 18h 38m 59.3s Above path Day 0 about 15 hours ahead  - Day 1 about 9 hours behind (24 hours)

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 2022/02/07 318,157,333 (decrease)
Earth Distance 2022/02/06 319,091,375 (decrease)
Earth Distance 2022/02/05 319,967,974 (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.

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

Today on Mars: 0036/13/24 Tuesday <<-- Days of the week offset 2 with Earth.

Today on Earth: 2022/02/10 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 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: 171.8 Sol Number: 358  Change in degrees is +.6
Previous SL:      171.2 Previous Sol:357

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:   221,993,384 km [24.8 km/s] Difference is -196214 <= -8009 km/hour at 8.5 on 02/10 (time 8:30)
Distance: Mars >> Sun per theskylive.com:   222,189,598 km [24.7 km/s] Difference is -191696 <= -8021 km/hour at 8.0 on 02/09 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   222,381,294 km [24.7 km/s] Difference is -193671 <= -8036 km/hour at 8.1 on 02/08 (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: Galaxy in path PGC 209223 RA 18h 55m 38.8s about 16 hours ahead
Star below TYC 6860-1021-1 Mg 12.12 RA 18h 51m 18.1s Day 0 about 10 hours ahead - Day 1 off screen to right
Galaxy above PGC 208810 RA 18h 51m 15.3s Day 0 about 10 hours ahead - Day 1 off screen to right

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 2022/02/10 315,422,499 (decrease)
Earth Distance 2022/02/09 316,343,024 (decrease)
Earth Distance 2022/02/08 317,180,777 (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 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

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 358 is in Month 13 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month  13 extends from Sol 335 through 362. See post 82 of Holidays topic for current details. <<== There are 27 days in Month 12
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 358 is Tuesday  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.

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 2022/02/13 312,731,213 (decrease)
Earth Distance 2022/02/12 313,640,955 (decrease)
Earth Distance 2022/02/11 314,517,452 (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 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

Month  13 extends from Sol 335 through 362. See post 82 of Holidays topic for current details. <<== There are 27 days in Month 12
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 361 is Friday  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: 0036/13/28 Saturday <<-- Days of the week offset 2 with Earth.

One day note: Last day of Month 13 on Mars

Today on Earth: 2022/02/14 Monday (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: 174.0 Sol Number: 362  Change in degrees is +.6
Previous SL:      173.4 Previous Sol:361

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:   221,232,417 km [24.8 km/s] Difference is -198600 <= -7944 km/hour at 8.0 on 02/14 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   221,431,017 km [24.8 km/s] Difference is -191078 <= -7962 km/hour at 7.0 on 02/13 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   221,622,095 km [24.8 km/s] Difference is -291444 <= -7977 km/hour at 7.0 on 02/12 (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: Bright TYC 6874-889-1 Mg 8.78 RA 19h 07m 53.6s above path - Day 0 about 16 hours ahead
Star TYC 6873-1022-1 RA 19h 03m 22.6s just 6 hours ahead. This object will likely be off the screen at this time tomorrow. - Day 1 off the screen

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

Today on Mars: 0036/14/03 Tuesday <<-- Days of the week offset 2 with Earth.

Today on Earth: 2022/02/17 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 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: 175.6 Sol Number: 365  Change in degrees is +.5
Previous SL:      175.1 Previous Sol:364

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:   220,655,235 km [24.9 km/s] Difference is -205076 <= -7888 km/hour at 9.0 on 02/17 (time 9:00)
Distance: Mars >> Sun per theskylive.com:   220,860,311 km [24.9 km/s] Difference is -181839 <= -7906 km/hour at 7.0 on 02/16 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   221,042,150 km [24.9 km/s] Difference is -190267 <= -7928 km/hour at 8.0 on 02/15 (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 above path:TYC 6875-2709-1 Mg 11.81 RA 19h 17m 24.8s - Day 0 about 14 hours ahead
Galaxy PGC 211364 RA 19h 13m 30.4s Day 0 about 12 hours ahead - Day 1 - still visible at far right ... about 14 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 2022/02/17 308,976,149 (decrease)
Earth Distance 2022/02/16 309,984,224 (decrease)
Earth Distance 2022/02/15 310,878,001 (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

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 365 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 27 days in Month 12
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 365 is Tuesday  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.

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 below path PGC 808608 RA 19h 27m 07.7s Day 0 about 16 hours ahead
TYC 6875-583-1 Mg 11.98 RA 19h 23m 05.3s Day 0 about 10 hours ahead - Day 1 at right edge of view about 14 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 2022/02/20 306,284,509 (decrease)
Earth Distance 2022/02/19 307,218,179 (decrease)
Earth Distance 2022/02/18 308,167,568 (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 368 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 27 days in Month 12
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 368 is Friday  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: 0036/14/07 Saturday <<-- Days of the week offset 2 with Earth.

Today on Earth: 2022/02/21 Monday (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: 177.9 Sol Number: 369  Change in degrees is +.6
Previous SL:      177.3 Previous Sol:368

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:   219,910,907 km [25.0 km/s] Difference is -187194 <= -7800 km/hour at 8.0 on 02/21 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   220,098,101 km [25.0 km/s] Difference is -187878 <= -7828 km/hour at 8.0 on 02/20 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   220,285,979 km [25.0 km/s] Difference is -196078 <= -7872 km/hour at 8.0 on 02/19 (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
