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

Today on Mars: 0036/05/07 Friday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/06/08 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: 2 <<== The Astronomical month will increment when longitude reaches 60 degrees

Solar Longitude: 055.7  Sol Number: 118  Change in degrees is +.4
Previous SL:      055.3  Previous Sol:117

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#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:   248,340,211 km [22.1 km/s] Difference is +053825 <= 2153 km/hour at 8.0 on 06/08 (time:8:00)
Distance: Mars >> Sun per theskylive.com:   248,286,386 km [22.1 km/s] Difference is +052024 <= 2214 km/hour at 7.0 on 06/07 (time:7:00)
Distance: Mars >> Sun per theskylive.com:   248,234,362 km [22.1 km/s] Difference is +053398 <= 2272 km/hour at 7.3 on 06/06 (time:7:30)

Next up: Micro-Boomer: HIP 39410 Magnitude 10.19 above path Day 0 about 20 hours ahead
Next up: Mini-Boomer: HIP 39344 Magnitude 7.81 just above path Day 0 about 15 hours ahead
Star TYC 1388-1150-1 Magnitude 11.79 in path Day 1 just below path about 7 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.

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 344,170,912
Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:342:000,000] [20:360,000,000]

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 05 extends from Sol 113 through 140. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 04

Sol 118 is Friday  in the Proposed Business calendar for Mars.  <<== Skip day occurred May 5th on Earth ... next will occur in June 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 June (10th) 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.

Galaxy PGC 1649210 RA 8h 12m 23.2s above path Day 0 about 11 hours ahead
Galaxy PGC 1647279 RA 8h 12m 22.0s in path Day 0 about 11 hours ahead
We have a nice assortment of galaxies in the view today ....
Galaxy PGC 1653231 RA 8h 10m 6.3s well above path Day 1 about 11 hours behind
Star TYC 1389-122-1 Magnitude 11.75 well below path Day 1 about 10 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.

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 347,838,564
Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers.
Light travel time today is between 19 and 20 minutes. Communications delay would be 38+ minutes round trip. [19:342:000,000] [20:360,000,000]

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 121 is in Month 05 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 05 extends from Sol 113 through 140. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 04

Sol 121 is Monday  in the Proposed Business calendar for Mars.  <<== Skip day occurred June 11 on Earth ... next will occur in August 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 (4-5 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: 0036/05/10  Tuesday <<-- Days of the week are not in alignment with Earth. 

Today on Earth: 2021/06/13 sunday (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: 2 <<== The Astronomical month will increment when longitude reaches 60 degrees

Solar Longitude: 057.9  Sol Number: 122  Change in degrees is +.4
Previous SL:      057.5  Previous Sol:121

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#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:   248,575,714 km [22.0 km/s] Difference is +044411 <= 1850 km/hour at 7.5 on 06/13 (time:7:30)
Distance: Mars >> Sun per theskylive.com:   248,531,303 km [22.0 km/s] Difference is +047769 <= 1911 km/hour at 7.5 on 06/12 (time:7:30)
Distance: Mars >> Sun per theskylive.com:   248,483,534 km [22.0 km/s] Difference is +043210 <= 1973 km/hour at 6.5 on 06/11 (time:6:30)

Next up: Mini-Boomer HIP 40404 Magnitude 8.37 below path Day 0 about 12 hours ahead
We have a nicely proportioned galaxy in the view today ... NGC 2545 RA 8h 14m 14.4s Magnitude 13.20 above path and just ahead of Mars
Galaxy PGC 1649210 RA 8h 12m 23.2s above path Day 1 about 12 hours behind
Galaxy PGC 1647279 RA 8h 12m 22.0s in path Day 1 about 11 hours behind
