Today on Earth: 2021/07/28 Wednesday (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: 077.6 Sol Number: 166 Change in degrees is +.5
Previous SL: 077.1 Previous Sol:165
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: 249,044,990 km [22.0 km/s] Difference is -023152 <= 0926 km/hour at 8.5 on 07/28 (time:8:30)
Distance: Mars >> Sun per theskylive.com: 249,068,142 km [22.0 km/s] Difference is -019901 <= 0865 km/hour at 7.5 on 07/27 (time:7:30)
Distance: Mars >> Sun per theskylive.com: 249,088,043 km [22.0 km/s] Difference is -020461 <= 0802 km/hour at 8.5 on 07/26 (time:8:30)
Next up: A micro-Boomer is in (just below) the path today: HIP 49518 Magnitude 7.34 about 10 hours ahead on Day 0
PGC 1420566 RA 10h 4m 32.9s Day 0 12 hours ahead Day 1 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.
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 380,319,998
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 20 and 22 minutes. Communications delay would be 40+ minutes round trip. [20:360,000,000] [21:390,000,000]
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 166 is Thursday 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.

Today on Mars: 0036/06/28 Saturday <<-- Days of the week are not in alignment with Earth.
One day note: <<== skipped Friday in last week of a quarter. The gap of weekdays is now back up to 2
Additional note: This was a four Sol work week in the proposed calendar on Mars. This design insures symmetry across the calendar.
I would like to (again) give credit to RobertDyck for the insight leading to this feature of the proposed Business calendar for Mars.

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 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.

Next up: Galaxy PGC 1384101 RA 10h 28m 37.5s above path about 15 hours ahead on Day 0

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 384,195,950
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 20 and 22 minutes. Communications delay would be 40+ minutes round trip. [20:360,000,000] [21:390,000,000]
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 179 is Thursday 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.

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 387,052,260
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 20 and 22 minutes. Communications delay would be 40+ minutes round trip. [20:360,000,000] [21:390,000,000]
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.

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 387,052,260
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 20 and 22 minutes. Communications delay would be 40+ minutes round trip. [20:360,000,000] [21:390,000,000]
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 188 is Saturday 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.

Today on Mars: 0036/07/22 Sunday <<-- Days of the week are not in alignment with Earth.
Today on Earth: 2021/08/20 Friday (Earth Date) Post Title: Today on Mars [Perihelion occurred August 3, 2020 Earth Calendar]
One Day Note: Mercury passed Mars in the View from Earth during the Sol just ended.
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: 087.7 Sol Number: 189 Change in degrees is +.5
Previous SL: 087.2 Previous Sol:188
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: 248,130,848 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)
Distance: Mars >> Sun per theskylive.com: 248,239,931 km [22.1 km/s] Difference is -050784 <= 2208 km/hour at 7.5 on 08/18 (time:7:30)
Next up: Star TYC 268-344-1 Magnitude 11.14 just above path Day - about 13 hours ahead
PGC 1324915 above PGC 1322083 below Day 0 aout 15 hours ahead - Day 1 5.5 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 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
