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

Today on Mars: 0036/02/10 Tuesday <<-- Days of the week are not in alignment with Earth.  <<== Last day for Month 1 of 24

Today on Earth: 2021/03/18 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

Martian Year: 36  Martian Month in 1 month format: 12 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 018.6  Sol Number: 38  Change in degrees is +.5
Previous SL:      018.1  Previous Sol: 37

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:   239,664,351 km [22.9 km/s] Difference is +145214 <= 6454 km/hour at 8.0 on 03/18 (time:8:00)
Distance: Mars >> Sun per theskylive.com:   239,519,137 km [22.9 km/s] Difference is +161700 <= 6493 km/hour at 9.5 on 03/17 (time:9:30)
Distance: Mars >> Sun per theskylive.com:   239,357,437 km [22.9 km/s] Difference is +156830 <= 6546 km/hour at 8.6 on 03/16 (time:8:36)

Next up: Star TYC 1816-812-1 Magnitude 9.84 just below path Day 0 about 15 hours ahead - might be good for two days
Note Boomer below path: HIP 20513 Magnitude 6.85 below path about 8 hours past - will be out of view tomorrow
Star TYC 1816-958-1 Magnitude 10.54 - Day 1 above and about 18 hours behind ... last day for 958
Star TYC 1816-1776-1 Magnitude 11.42 Just above path Day 2 at the edge of the view - last day for 1776

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 038 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
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.

Sol 042 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: 0036/02/15 Sunday <<-- Days of the week are not in alignment with Earth.  <<== Last day for Month 1 of 24

Today on Earth: 2021/03/23 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 1 month format: 12 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 020.9  Sol Number: 43  Change in degrees is +.4
Previous SL:      020.5  Previous Sol: 42

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:   240,427,123 km [22.8 km/s] Difference is +146758 <= 6245 km/hour at 8.5 on 03/23 (time:8:30)
Distance: Mars >> Sun per theskylive.com:   240,280,365 km [22.9 km/s] Difference is +157824 <= 6287 km/hour at 9.0 on 03/22 (time:9:00)
Distance: Mars >> Sun per theskylive.com:   240,122,541 km [22.9 km/s] Difference is +152578 <= 6331 km/hour at 7.7 on 03/21 (time:7:54)

Next up - TYC 1830-72-1 Magnitude 11.51 below path Day 0 - about 20 hours ahead
Next up - one high and one low - TYC 1830-1055-1 Magnitude 11.28 Day 0 about 16 hours ahead
TYC 1829-327-1 Magnitude 9.82 Day 1 Still visible at edge of view on right - Definitely the last day for 327
Note Boomer in passing: HIP 21459 Magnitude 6.00 Below path Day 1 Surprise! Still visible ... about 11 hours behind and in lower right of view

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.  Earth Distance at last update (here) was km 248,830,744
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 13 and 14 minutes. Communications delay would be 26+ minutes round trip. [13:234,000,000] [14:252,000,000]

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.

Distance: Mars >> Sun per theskylive.com:   241,012,024 km [22.8 km/s] Difference is +147546 <= 6072 km/hour at 7.8 on 03/27 (time:7:48)
Distance: Mars >> Sun per theskylive.com:   240,864,478 km [22.8 km/s] Difference is +140694 <= 6117 km/hour at 7.5 on 03/26 (time:7:30)

Next up: Galaxy PGC 1698308 above path Day 0 way ahead of Mars about 22 hours ... might be good for two days
Next up: Galaxy UGC 3165 RA 4h 47m 27.8s nice top view with good definition Day 0 above and even with mars ... likely good for just one day
Star TYC 1831-1062-1 Magnitude 9.66 above path Day 1 about 14 hours behind .... last day for 1062
Galaxy PGC 1696189 RA 4h 45m 41.8s above path Day 1 near edge of view ... last day for 189

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.  Earth Distance at last update (here) was km 255,818,745
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 14 and 15 minutes. Communications delay would be 28+ minutes round trip. [14:252,000,000] [15:270,000,000]

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

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.

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

Today on Mars: 0036/02/23 Monday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/04/01 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

Martian Year: 36  Martian Month in 1 month format: 1 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 025.1  Sol Number: 51  Change in degrees is +.4
Previous SL:      024.7  Previous Sol: 50

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:   241,731,586 km [22.7 km/s] Difference is +143216 <= 5846 km/hour at 9.0 on 04/01 (time:9:00)
Distance: Mars >> Sun per theskylive.com:   241,588,370 km [22.7 km/s] Difference is +144359 <= 5892 km/hour at 8.5 on 03/31 (time:8:30)
Distance: Mars >> Sun per theskylive.com:   241,444,011 km [22.7 km/s] Difference is +140693 <= 5936 km/hour at 8.0 on 03/30 (time:8:00)

Next up: Star TYC 1845-298-1 Magnitude 11.35 in path Day 0 about 24 hours ahead - should be good for two days
Next up: Star TYC 1845-846-1 Magnitude 8.56 in path Day 0 about 20 hours ahead
Galaxy PGC 1702773 RA 5h 00m 01.2s in path Day 1 About 5 hours behind - last day for 773

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.  Earth Distance at last update (here) was km 261,382,522
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 14 and 15 minutes. Communications delay would be 28+ minutes round trip. [14:252,000,000] [15:270,000,000]

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

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

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

since the data from the seismic unit is working I decided to check the weather web site for insight and was surprised to see the pressure sensors were working once more.
The location of the lander is in the Northern Hemisphere and its coming up on spring as I read the charts supplied.

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 down toward horizontal.  Earth Distance at last update (here) was km 269,472,267
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 14 and 15 minutes. Communications delay would be 28+ minutes round trip. [14:252,000,000] [15:270,000,000]

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

Mars is executing the "Retrograde" movement as seen from Earth. Earth is passing "under" Mars.

Today on Mars: 0036/03/04 Wednesday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/04/10 Saturday (Earth Date) Post Title: Today on Mars   [Perihelion occurred August 3, 2020 Earth Calendar]

One day note: This is the 1000th post in the series offered to show a business calendar for Mars. 

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

Martian Year: 36  Martian Month in 1 month format: 1 <<== The Astronomical month will increment when longitude reaches 30 degrees

Solar Longitude: 029.3  Sol Number: 60  Change in degrees is +.5
Previous SL:      028.8  Previous Sol: 59

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:   242,943,459 km [22.6 km/s] Difference is +139317 <= 5421 km/hour at 9.0 on 04/10 (time:9:00)
Distance: Mars >> Sun per theskylive.com:   242,804,142 km [22.6 km/s] Difference is +124687 <= 5469 km/hour at 7.3 on 04/09 (time:7:18)
Distance: Mars >> Sun per theskylive.com:   242,679,455 km [22.6 km/s] Difference is +129663 <= 5517 km/hour at 8.5 on 04/08 (time:8:30)

Next up: Galaxy PGC 1712963 RA 5h 26m 23.9s below path Day 0 about 16 hours ahead
TYC 1851-1080-1 Magnitude 11.68 Well below path Day 1 out of view

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 down toward horizontal.  Earth Distance at last update (here) was km 276,303,977
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 15 and 16 minutes. Communications delay would be 30+ minutes round trip. [15:270,000,000] [16:288,000,000]

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 060 is in Month 03 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 03 extends from Sol 057 through 85. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 01

Sol 060 is Wednesday  in the Proposed calendar for Mars.  <<== Skip day occurred March 30th on Earth ... next will occur in May 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 May 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.
