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

Today on Mars: 0036/07/23  Monday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/08/21 Saturday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html

Martian Year: 36  Martian Month in 12 month format: 3 <<== The Astronomical month will increment when longitude reaches 90 degrees

Solar Longitude: 088.1  Sol Number: 190  Change in degrees is +.4
Previous SL:      087.7  Previous Sol:189

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

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

Note#3: The computations below are dependent upon both the computations provided by the reference web site and by accuracy of recording of the time of observations.  The calculations use tenths of hours.  The Sun Distance needs to be captured at the moment the time increments to a given tenth.

Distance: Mars >> Sun per theskylive.com:   248,068,709 km [22.1 km/s] Difference is -062139 <= 2390 km/hour at 9.0 on 08/21 (time:9:00)
Distance: Mars >> Sun per theskylive.com:   248,130,848 km [22.1 km/s] Difference is -051199 <= 2327 km/hour at 7.0 on 08/20 (time:7:00)
Distance: Mars >> Sun per theskylive.com:   248,182,047 km [22.1 km/s] Difference is -057884 <= 2270 km/hour at 9.0 on 08/19 (time:9:00)

Next up: Star TYC 268-466-1 Magnitude 9.06 below path Day 0 about 11 hours ahead
Next up: Bracket pair: Galaxy PGC 33441 Magnitude 15.10 above about 14 hours ahead
Star TYC 268-344-1 Magnitude 11.14 just above path Day - about 13 hours ahead - Day 1 about 11 hours past Mars

As a general observation ... In recent days I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.  Earth Distance at last update here) was km 390,083,083
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 21 and 22 minutes. Communications delay would be 42+ minutes round trip. [21:390,000,000] [22:420,000,000]

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

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

Sol 190 is Monday  in the Proposed Business calendar for Mars.  <<== Skip day occurred July 21 the next skip day is expected August 27 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 August (27th on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may 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.

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.

In recent days, the curve has been slowly bending down through horizontal.  Earth Distance at last update here) was km 391,213,549
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 21 and 22 minutes. Communications delay would be 42+ minutes round trip. [21:390,000,000] [22:420,000,000]

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.

Galaxy PGC 1279832 RA 11h 20m 05.1s below path Day 0 about 10 hours ahead - about 12 hours behind on Day 1

As a general observation ... In recent days I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.  Earth Distance at last update here) was km 392,364,430
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 21 and 22 minutes. Communications delay would be 42+ minutes round trip. [21:390,000,000] [22:420,000,000]

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.

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.

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html

Martian Year: 36  Martian Month in 12 month format: 4 <<== The Astronomical month will increment when longitude reaches 120 degrees

Solar Longitude: 093.8  Sol Number: 202  Change in degrees is +.4
Previous SL:      093.4  Previous Sol:201

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

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

Note#3: The computations below are dependent upon both the computations provided by the reference web site and by accuracy of recording of the time of observations.  The calculations use tenths of hours.  The Sun Distance needs to be captured at the moment the time increments to a given tenth.

Distance: Mars >> Sun per theskylive.com:   247,201,423 km [22.1 km/s] Difference is -072502 <= 3152 km/hour at 6.5 on 09/03 (time:6:30)
Distance: Mars >> Sun per theskylive.com:   247,273,925 km [22.1 km/s] Difference is -075849 <= 3096 km/hour at 7.5 on 09/02 (time:7:30)
Distance: Mars >> Sun per theskylive.com:   247,349,774 km [22.1 km/s] Difference is -068335 <= 3037 km/hour at 7.0 on 09/01 (time:7:00)

Galaxy just below path PGC 1261351 RA 11h 31m 53.8s Day 0 about 12 hours ahead - Day 1 a out 11 hours behind

As a general observation ... In recent days I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.  Earth Distance at last update here) was km 392,364,430
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 21 and 22 minutes. Communications delay would be 42+ minutes round trip. [21:390,000,000] [22:420,000,000]

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.

'a martian calender...'

Last edited by Mars_B4_Moon (Today 08:21:19)

Most NewMars members may not realize that a key feature of the Business Calendar that makes it such a pleasure to work with was contributed by RobertDyck.

The days of the week always fall on the same name days.

The year automatically self-adjusts to the current nanosecond at the stroke of midnight on New Year's Day.

All months are 28 Sols except for four at the end of each quarter. Those are 27 days with Friday skipped.

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

Special Bulletin: Opposition in October on Earth

Mars and Earth will be on opposite sides of the Sun in October.

Electronic communications will be suspended.

Things to watch for include securing equipment on Mars to pause communications for about two Earth weeks.

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

Today on Mars: 0036/08/11  Wednesday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/09/07 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

Martian Year: 36  Martian Month in 12 month format: 4 <<== The Astronomical month will increment when longitude reaches 120 degrees

Solar Longitude: 095.6  Sol Number: 206  Change in degrees is +.5
Previous SL:      095.1  Previous Sol:205

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

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

Note#3: The computations below are dependent upon both the computations provided by the reference web site and by accuracy of recording of the time of observations.  The calculations use tenths of hours.  The Sun Distance needs to be captured at the moment the time increments to a given tenth.

Distance: Mars >> Sun per theskylive.com:   246,878,157 km [22.2 km/s] Difference is -079629 <= 3388 km/hour at 8.5 on 09/07 (time:8:30)
Distance: Mars >> Sun per theskylive.com:   246,957,786 km [22.2 km/s] Difference is -083243 <= 3330 km/hour at 9.0 on 09/06 (time:9:00)
Distance: Mars >> Sun per theskylive.com:   247,041,029 km [22.2 km/s] Difference is -078510 <= 3271 km/hour at 8.0 on 09/05 (time:8:00)

Next up : Galaxy PGC 1232290 RA 11h 44m 20.9 s just below path Day 0 about 16 hours ahead

As a general observation ... In recent days I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.  Earth Distance at last update here) was km 393,750,365
Mars and Earth are approaching opposition.  The two planets will soon be on opposite sides of the Sun. Earth Distance will reach a maximum.
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 21 and 22 minutes. Communications delay would be 42+ minutes round trip. [21:390,000,000] [22:420,000,000]

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.

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

Today on Mars: 0036/08/15  Sunday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/09/11 Saturday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html

Martian Year: 36  Martian Month in 12 month format: 4 <<== The Astronomical month will increment when longitude reaches 120 degrees

Solar Longitude: 097.4  Sol Number: 210  Change in degrees is +.4
Previous SL:      097.0  Previous Sol:209

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

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

Note#3: The computations below are dependent upon both the computations provided by the reference web site and by accuracy of recording of the time of observations.  The calculations use tenths of hours.  The Sun Distance needs to be captured at the moment the time increments to a given tenth.

Distance: Mars >> Sun per theskylive.com:   246,542,876 km [22.2 km/s] Difference is -088159 <= 3613 km/hour at 7.5 on 09/11 (time:7:30)
Distance: Mars >> Sun per theskylive.com:   246,631,035 km [22.2 km/s] Difference is -078628 <= 3558 km/hour at 7.1 on 09/10 (time:7:01)
Distance: Mars >> Sun per theskylive.com:   246,709,663 km [22.2 km/s] Difference is -087554 <= 3502 km/hour at 9.0 on 09/09 (time:9:00)

Next up: Star TYC 273-371-1 Magnitude 11.18 Just below path Day 0 about 11 hours ahead
A Boomer just below path and just below display range - Day 0 about 12 hours ahead HIP 57756 Magnitude 3.55 Day 1 about 12 hours past

As a general observation ... In recent days I've become increasingly interested in knowing what the larger view of the sky might be like.
The site: theskylive.com does a terrific job of matching the view from Earth towards Mars, against a background of actual astronomical plates.
I wish there were a way (or rather, I wish I ** knew ** about a way that may exist) to enlarge the view until the entire galaxy is in view.
Update 2021/07/30 I wrote to an astronomer to ask if there might be a web site with a view showing the galaxy in context of a given view.

Note: The curve of the path of Mars as seen against the background of stars is now a line trending noticeably down and East as seen from Earth
In recent days, the curve has been slowly bending down through horizontal.  Earth Distance at last update here) was km 394,100,123
Mars and Earth are approaching opposition.  The two planets will soon be on opposite sides of the Sun. Earth Distance will reach a maximum.
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 21 and 22 minutes. Communications delay would be 42+ minutes round trip. [21:390,000,000] [22:420,000,000]

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

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

Sol 210 is in Month 08 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 08 extends from Sol 196 through 223. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 08

Sol 210 is Sunday  in the Proposed Business calendar for Mars.  <<== Skip day occurred August 25th the next skip day is expected October 1 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 October (1st on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may 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.
