Today on Earth: 2020/12/25 Friday (Earth Date) Title: Today on Mars [Perihelion occurred August 3, 2020 Earth Calendar]

Today on Mars: 0035/23/13 Friday <<-- Days of the week are in alignment with those on Earth. Earth December 29, 2020 next alignment estimate.

One day note: Today is Day 4 of the Astronomical New Year on Earth

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

Martian Year: 35 Martian Month in 12 month format: 12 <<== The Astronomical month will increment when longitude reaches 360 degrees

Solar Longitude: 336.8 Sol Number: 626 Change in degrees is +.5
Previous SL: 336.3 Previous Sol: 625

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 the computations provided by the reference web site. The reference web site is NOT reporting observations. It is instead computing positions of the various objects by extrapolating from past observations. Another factor is accuracy of recording of the time of observations. The calculations use tenths of hours. The web site display updates several times per second.

Distance of Mars from the Sun is given by theskylive.com as: 224,358,220 km Difference is +204720 <= 8124 km/hour at 10.3 on 12/24
Distance of Mars from the Sun is given by theskylive.com as: 224,153,500 km Difference is +191255 <= 8104 km/hour at 9.1 on 12/23
Distance of Mars from the Sun is given by theskylive.com as: 223,962,245 km Difference is +184721 <= 8102 km/hour at 9.5 on 12/22

Next up: Star TYC 617-589-1 Magnitude 10.88 Day 0 above and just ahead of Mars
Spiral galaxy IC 114 Magnitude 15.20 Day 1 Above and about 20 hours behind Mars
Star TYC 614-178-1 Magnitude 10.61 Day 2 Above path and about 36 hours behind - last day for 6f14

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 time is between 6 and 7 minutes. Communications delay would be 10+ minutes round trip. [6:120,000,000] [7:140,000,000]

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.

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.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. Per www.planetary.org this will occur February 7, 2021 (Year 36)
The next Skip Day will occur in December 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

Today on Mars: 0035/23/28 Saturday <<-- Days of the week are out of alignment with those on Earth. Earth February 5, 2021 next alignment estimate.

Today on Earth: 2021/01/10 Sunday (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: 35 Martian Month in 12 month format: 12 <<== The Astronomical month will increment when longitude reaches 360 degrees

Solar Longitude: 345.3 Sol Number: 641 Change in degrees is +.5
Previous SL: 344.8 Previous Sol: 640

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: 227,662,146 km Difference is +146724 <= 8118 km/hour at 8.5 on 01/10 (time:8:30)
Distance of Mars from the Sun is given by theskylive.com as: 227,475,422 km Difference is +214425 <= 8122 km/hour at 9.5 on 01/09 (time:9:30)

Star HIP 8827 Magnitude 7.02 Day 2 past Mars and about to disappear from 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

Light travel time is between 6 and 7 minutes. Communications delay would be 12+ minutes round trip. [6:120,000,000] [7:150,000,000]

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.

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: 228,623,431 km Difference is +185901 <= 8082 km/hour at 7.2 on 01/15 (time:7:12)
Distance of Mars from the Sun is given by theskylive.com as: 228,437,530 km Difference is +181233 <= 8090 km/hour at 8.2 on 01/14 (time:8:12)
Distance of Mars from the Sun is given by theskylive.com as: 228,256,297 km Difference is +190273 <= 8096 km/hour at 9.8 on 01/13 (time:9:48)

Next up: Galaxy PGC 1445761 RA 2h 8m 35.8s below path Day 0 About 24 hours ahead
Next up: Star TYC 6365-264-1 Magnitude 11.40 Just above path Day 0 about 12 hours ahead
Galaxy PGC 1437247 below path Day 1 About 14 hours behind - last day for 1437247

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 time is between 8 and 9 minutes. Communications delay would be 16+ minutes round trip. [8:144,000,000] [9:162,000,000]

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 646 is in Month 24 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 24 extends from Sol 642 through 668. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 22

Sol 646 is Thursday in the Proposed calendar for Mars. <<== Skip day occurred November 22nd, 2020 on Earth

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. Per www.planetary.org this will occur February 7, 2021 (Year 36)
The next Skip Day will occur in February 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.
