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

Today on Mars: 0036/01/14 Saturday <<-- Days of the week are not in alignment with Earth. Skip Day will be reset per jussieu.fr web site

Today on Earth: 2021/02/22 Monday (Earth Date) 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 1 month format: 12 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 007.1  Sol Number: 14  Change in degrees is +.5 <<== Skip day reset to match jussieu.fr web site
Previous SL:      006.6  Previous Sol: 13

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 will occur near 70 degrees Ls (per www.planetary.org)

Note: 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 of Mars from the Sun is given by theskylive.com as:   235,703,214 km Difference is +179217 <= 7315 km/hour at 7.9 on 02/22 (time:7:54)
Distance of Mars from the Sun is given by theskylive.com as:   235,523,997 km Difference is +165992 <= 7345 km/hour at 7.4 on 02/21 (time:7:42)
Distance of Mars from the Sun is given by theskylive.com as:   235,358,005 km Difference is +187308 <= 7374 km/hour at 8.8 on 02/20 (time:8:48)

Next Up: A bright star from HIP series: HIP 15996 Magnitude 8.66 just above path Day 0 just ahead of Mars - good for one day
Star TYC 1241-83-1 Magnitude 11.49 above path Day 1 About 18 hours past - last day for 83
Galaxy PGC 1612067 RA 3h 23m 19.5s below path Day 2 Just visible at the West edge of the view - definitely last day for 1612067

Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
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 11 and 12 minutes. Communications delay would be 20+ minutes round trip. [11:198,000,000] [12:216,000,000]

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 014 is Saturday  in the Proposed calendar for Mars.  <<== Skip day occurred February 4, 2021 on Earth and again on February 11, 2021

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 March 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.

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

Today on Mars: 0036/01/19 Thursday <<-- Days of the week are not in alignment with Earth.

Today on Earth: 2021/02/27 Saturday (Earth Date) 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 1 month format: 12 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 009.5  Sol Number: 19  Change in degrees is +.5
Previous SL:      009.0  Previous Sol: 18

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 will occur near 70 degrees Ls (per www.planetary.org)

Note: 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 of Mars from the Sun is given by theskylive.com as:   236,570,404 km Difference is +178925 <= 7157 km/hour at 8.0 on 02/27 (time:8:00)
Distance of Mars from the Sun is given by theskylive.com as:   236,391,479 km Difference is +168958 <= 7190 km/hour at 7.0 on 02/26 (time:7:00)
Distance of Mars from the Sun is given by theskylive.com as:   236,222,521 km Difference is +173317 <= 7222 km/hour at 7.5 on 02/25 (time:7:30)

Next up: A boomer: HIP 17026 Magnitude 6.48 just below path Day 0 about 12 hours ahead
TYC 1246-1050-1 Magnitude 10.77 below path Day Day 1 near edge of view - last day for 1050

Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
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 11 and 12 minutes. Communications delay would be 20+ minutes round trip. [11:198,000,000] [12:216,000,000]

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

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

Month 01 extends from Sol 001 through 028. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 01
Direct path to source: http://newmars.com/forums/viewtopic.php … 57#p154257
Sol 019 is Thursday  in the Proposed calendar for Mars.  <<== Skip day occurred February 4, 2021 on Earth and again on February 11, 2021

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 March 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.

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.

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

Today on Mars: 0036/01/24 Tuesday <<-- Days of the week are not in alignment with Earth.

Today on Earth: 2021/03/04 Thursday (Earth Date) 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 1 month format: 12 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 011.9  Sol Number: 24  Change in degrees is +.5
Previous SL:      011.4  Previous Sol: 23

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 will occur near 70 degrees Ls (per www.planetary.org)

Note: 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:   237,423,302 km [23.1 km/s] Difference is +179548 <= 6986 km/hour at 8.9 on 03/04 (time:8:54)
Distance: Mars >> Sun per theskylive.com:   237,243,754 km [23.2 km/s] Difference is +155858 <= 7021 km/hour at 7.2 on 03/03 (time:7:12)
Distance of Mars from the Sun is given by theskylive.com as:   236,906,560 km Difference is +158092 <= 7089 km/hour at 7.3 on 03/01 (time:7:18)

Next up: Star TYC 1260-271-1 Magnitude 12.08 Above path Day 0 ahead about 15 hours - may be good for two days
Star TYC 1260-305-1 Magnitude 11.02 just above path Day 1 Right at Mars - likely good for another day!
Star TYC 1260-812-1 Magnitude 11.76 in path Day 2 - still visible but at the edge of the screen - definitely the last day for 812
Galaxy PGC 1649756 RA 3h 46m 57.1s in path Day 1 About 5 hours behind - last day for 756

Note: The curve of the path of Mars as seen against the background of stars is now a line trending upward and East as seen from Earth
However, in recent days, the curve has been slowly bending down toward horizontal.
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 12 and 13 minutes. Communications delay would be 24+ minutes round trip. [12:216,000,000] [13:234,000,000]

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 024 is in Month 01 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 01 extends from Sol 001 through 028. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 01

Sol 024 is Tuesday  in the Proposed calendar for Mars.  <<== Skip day occurred February 4, 2021 on Earth and again on February 11, 2021

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. <<== The current year on Mars is 36
