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

Today on Mars: 0036/15/03 Tuesday <<-- Days of the week offset 3 with Earth. 

Today on Earth: 2022/03/18 Friday (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: 192.2 Sol Number: 393  Change in degrees is +.6
Previous SL:      191.6 Previous Sol:392

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:   215,468,366 km [25.5 km/s] Difference is -167625 <= -6984 km/hour at 8.0 on 03/18 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   215,635,991 km [25.5 km/s] Difference is -168564 <= -7024 km/hour at 8.0 on 03/17 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   215,804,555 km [25.4 km/s] Difference is -162484 <= -7065 km/hour at 8.0 on 03/16 (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 just above path: TYC 6352-28-1 Mg 11.20 RA 20h 48m 31.0s Day 0 about 15 hours ahead
TYC 6339-557-1 Mg 11.70 RA 20h 45m 06.4s [6339-100-1/6339-1742-1/6339-338-1] Day 0 12 hours ahead - Day 1 about 12 hours behind

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

Note: The curve of the path of Mars as seen against the background of stars is now a line trending slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/18 282,329,945 (decrease)
Earth Distance 2022/03/17 283,289,138 (decrease)
Earth Distance 2022/03/16 284,170,814 (decrease)

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

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 393 is in Month 15 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month  15 extends from Sol 391 through 418. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 15
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 393 is Monday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. <<== The current year on Mars is 36
Per www.planetary.org this occurred February 7, 2021 (on Earth). The new Mars Year is 36.

The last Skip Day occurred in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
For those who may not be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter
337 Earth days were observed to elapse in the 2020 weekday cycle. There were 7 week day transitions and 2 Quarter ends.
The next cycle began on the first Sol of the period of coincidence. The  alignment of weekdays interval is in the range: (310 - 337)
Use Search Term Alignment to find the first day of a period of coincidence.

Next up - Galaxy pair bracket path: PGC 869726 RA 20h 57m 50.4s and PGC 868916 - Day 0 about 15 hours ahead
PGC 866986 RA 20h 53m 53.4s Day 0 about 9 hours ahead - Day1 - just in view at far right  - about 15 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.
Update 2022/01/22 What I'm asking for is a "Zoom Out" feature.  If anyone knows of such a service, please contact the NewMars portal.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/21 279,583,888 (decrease)
Earth Distance 2022/03/20 280,473,624 (decrease)
Earth Distance 2022/03/19 281,447,244 (decrease)

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

Sol 396 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 last Skip Day occurred in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
For those who may not be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter
337 Earth days were observed to elapse in the 2020 weekday cycle. There were 7 week day transitions and 2 Quarter ends.
The next cycle began on the first Sol of the period of coincidence. The  alignment of weekdays interval is in the range: (310 - 337)
Use Search Term Alignment to find the first day of a period of coincidence.

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:   214,806,692 km [25.6 km/s] Difference is -165364 <= -6805 km/hour at 8.3 on 03/22 (time 8:18)

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. <<== The current year on Mars is 36
Per www.planetary.org this occurred February 7, 2021 (on Earth). The new Mars Year is 36.

The last Skip Day occurred in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
For those who may not be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter
337 Earth days were observed to elapse in the 2020 weekday cycle. There were 7 week day transitions and 2 Quarter ends.
The next cycle began on the first Sol of the period of coincidence. The  alignment of weekdays interval is in the range: (310 - 337)
Use Search Term Alignment to find the first day of a period of coincidence.

Today on Earth: 2022/03/25 Friday (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: 196.3 Sol Number: 400  Change in degrees is +.6
Previous SL:      195.7 Previous Sol:399
---
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:   214,332,219 km [25.6 km/s] Difference is -153312 <= -6666 km/hour at 7.0 on 03/25 (time 7:00)
Distance: Mars >> Sun per theskylive.com:   214,485,531 km [25.6 km/s] Difference is -161009 <= -6708 km/hour at 8.0 on 03/24 (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: Crouching rabbit asterism - TYC 6530-690-1 Mg 11.58 RA 21h 09m 20.0s below path Day 0 about 11 hours ahead
Star below asterism of V pointing down to star: TYC 6350-893-1 Mg 12.04 RA 21h 06m 35.4s Day 0 - about 12 hours ahead - Day 1 about 11 hours behind

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

Note: The curve of the path of Mars as seen against the background of stars is now a line trending slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/25 275,961,770 (decrease)
Earth Distance 2022/03/24 276,880,923 (decrease)
Earth Distance 2022/03/23 277,778,899 (decrease)

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

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:   213,851,683 km [25.7 km/s] Difference is -157636 <= -6514 km/hour at 8.2 on 03/28 (time 8:12)
Distance: Mars >> Sun per theskylive.com:   214,009,319 km [25.7 km/s] Difference is -157501 <= -6563 km/hour at 8.0 on 03/27 (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
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: slim pickings: Eligible stars (or galaxies) must be at least 9 hours ahead of Mars in order to be likely to be visible 24 hours later.
TYC 6351-389-1 Mg 10.61 RA 21h 15m 37.4s Day 0 about 15 hours ahead - Day 1 about 9 hours behind

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

Note: The curve of the path of Mars as seen against the background of stars is now a line trending slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/28 273,223,340 (decrease)
Earth Distance 2022/03/27 274,132,217 (decrease)
Earth Distance 2022/03/26 275,062,080 (decrease)

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

Sol 403 is in Month 15 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month  15 extends from Sol 391 through 418. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 15
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 403 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 last Skip Day occurred in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.
For those who may not be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter
337 Earth days were observed to elapse in the 2020 weekday cycle. There were 7 week day transitions and 2 Quarter ends.
The next cycle began on the first Sol of the period of coincidence. The  alignment of weekdays interval is in the range: (310 - 337)
Use Search Term Alignment to find the first day of a period of coincidence.

Update 2022/01/22 What I'm asking for is a "Zoom Out" feature.  If anyone knows of such a service, please contact the NewMars portal.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending slightly upward and East as seen from Earth
In recent days, the curve has been slowly bending up through horizontal, and on 2022/01/31, it is inclining slightly upward

Earth Distance 2022/03/31 270,455,348  (decrease)

Earth Distance 2022/03/29 272,258,354 (decrease)

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

Sol 406 is Monday  in the Proposed Business calendar for Mars.  Sol 339 was a skip day on Earth.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. <<== The current year on Mars is 36
Per www.planetary.org this occurred February 7, 2021 (on Earth). The new Mars Year is 36.

The last Skip Day occurred in February 2022 (on: 28th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
The next Skip day is expected in April 2022 (on 9th) on Earth.

For those who may not be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter
337 Earth days were observed to elapse in the 2020 weekday cycle. There were 7 week day transitions and 2 Quarter ends.
The next cycle began on the first Sol of the period of coincidence. The  alignment of weekdays interval is in the range: (310 - 337)
Use Search Term Alignment to find the first day of a period of coincidence.

Today on Earth: 2022/04/01 Friday (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: 200.4 Sol Number: 407  Change in degrees is +.6
Previous SL:      199.8 Previous Sol:406
---
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:   213,240,059 km [25.7 km/s] Difference is -150697 <= -6305 km/hour at 8.0 on 04/01 (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.

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: 2022/04/04 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: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 202.2 Sol Number: 410  Change in degrees is +.6
Previous SL:      201.6 Previous Sol:409
---
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:   212,790,862 km [25.8 km/s] Difference is -150435 <= -6150 km/hour at 8.5 on 04/04 (time 8:30)
Distance: Mars >> Sun per theskylive.com:   212,941,297 km [25.8 km/s] Difference is -148733 <= -6197 km/hour at 8.0 on 04/03 (time 8:00)

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


Next up : Three stars and a Galaxy across path: Top: TYC 6362-129-1 Mg 10.88 RA 21h 39m 21.9s Day 0 about 11 hours ahead
Galaxy in path: PGC 909904 RA 21h 36m 46.7s Day 0 about 15 hours ahead - should be good for 24 hours - Day 1 right at 10 hour mark
Note mini-Boomer ahead of Mars and below: HIP 106631 Mg 8.67 Day 0 about 7 hours ahead - Day 1 ** just ** visible at extreme 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 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 2022/04/04 266,853,666  (decrease)
Earth Distance 2022/04/03 267,817,466  (decrease)
Earth Distance 2022/04/02 269,624,733  (decrease)

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

Month  15 extends from Sol 391 through 418. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 15
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 410 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.

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 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

Mars and Earth are coming closer after Conjunction.  The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 17 and 18 minutes. Communications delay would be 34+ minutes round trip. [17:270,000,000/18:300,000,000]

In his online interview with Dr. Zubrin at the 2020 Mars Conference, Elon Musk reminded the audience that communications with Mars will necessarily include an intermediary station to handle traffic when the Sun is between Mars and Earth.  Communications delays in that circumstance will increase due to the extra distance to be covered.  Mr. Musk indicated he expects such communication will be handled by laser.  Location would be optimum at poles of solar plane.

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

Sol 412 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.

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 415 is Wednesday  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.

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

Today on Mars: 0036/15/26 Thursday <<-- Days of the week offset 4 with Earth.

Today on Earth: 2022/04/11 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: 7 <<== The Astronomical month will increment when longitude reaches 210 degrees

Solar Longitude: 206.4 Sol Number: 416  Change in degrees is +.6
Previous SL:      205.8 Previous Sol:415
---
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:   211,801,019 km [25.9 km/s] Difference is -137573 <= -5732 km/hour at 8.0 on 04/11 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   211,938,592 km [25.9 km/s] Difference is -138983 <= -5791 km/hour at 8.0 on 04/10 (time 8:00)
Distance: Mars >> Sun per theskylive.com:   212,077,575 km [25.9 km/s] Difference is -140479 <= -5853 km/hour at 8.0 on 04/09 (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
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 5808-1336-1 Mg 12.09 RA 22h 00 58.4s directly in path Day 0 about 17 hours ahead
Next up: A micro-Boomer: HIP 108647 RA 22h 00m 38.2s below path Day 0 about 14 hours ahead
PGC 163479 RA 21h 57m 00.8s Day 0 about 10 hours ahead - Day 1 about 14 hours behind ... at the very edge of the view on the 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 2022/04/11 260,650,555  (decrease)
Earth Distance 2022/04/10 261,478,666  (decrease)
Earth Distance 2022/04/09 262,436,130  (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]
