Today on Earth: 2021/07/03 Saturday (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: 066.7 Sol Number: 142 Change in degrees is +.5
Previous SL: 066.2 Previous Sol:141
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: 249,156,047 km [22.0 km/s] Difference is +015213 <= 0621 km/hour at 8.5 on 07/03 (time:8:30)
Distance: Mars >> Sun per theskylive.com: 249,140,834 km [22.0 km/s] Difference is +016756 <= 0684 km/hour at 8.0 on 07/02 (time:8:00)
Distance: Mars >> Sun per theskylive.com: 249,106,939 km [22.0 km/s] Difference is +019757 <= 0806 km/hour at 8.5 on 06/30 (time:8:30)
Next up: Star pair: TYC 1404-1580-1 Magnitude 10.99 Day 0 about 15 hours ahead
Next up: Star pair: TYC 1404-1597-1 Magnitude 12.72 below path Day 0 about 15 hours ahead
Galaxy PGC 1553419 RA 9h 3m 7.6s above path about 11 hours ahead Day 1 about 14 hours behind
Star 1397-1189-1 Magnitude 10.20 above path about 11 hours ahead Day 1 about 14 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 365,204,067
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 142 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.

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 (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.

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 365,204,067
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.

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.

Today on Mars: 0036/06/16 Monday <<-- Days of the week are not in alignment with Earth.
Today on Earth: 2021/07/17 Saturday (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: 072.8 Sol Number: 156 Change in degrees is +.5
Previous SL: 072.3 Previous Sol:155
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: 249,208,746 km [22.0 km/s] Difference is -006224 <= 0244 km/hour at 8.0 on 07/17 (time:8:00)
Distance: Mars >> Sun per theskylive.com: 249,214,700 km [22.0 km/s] Difference is -004019 <= 0183 km/hour at 6.5 on 07/16 (time:6:30)
Distance: Mars >> Sun per theskylive.com: 249,217,719 km [22.0 km/s] Difference is -003006 <= 0123 km/hour at 8.5 on 07/15 (time:8:30)
Next up: Slim pickings - the plates show many objects but few are identified: Star TYC 1410-688-1 Magnitude 11.14 Day 0 about 15 hours ahead
Star TYC 1410-726-1 Magnitude 11.22 in path Day 0 about 20 hours ahead Day 1 about 5 hours past Mars
We have a pair of micro-boomers in the mix HIP 47233 Magnitude 8.59 above the path still visible Day 1 about 15 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 372,762,783
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 156 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.

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.

2021/07/21 The French web site used for reference for this daily report is showing 159 as today's Sol.
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

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: 249,088,043 km [22.0 km/s] Difference is -020461 <= 0802 km/hour at 8.5 on 07/26 (time:8:30)
Distance: Mars >> Sun per theskylive.com: 249,108,504 km [22.0 km/s] Difference is -015954 <= 0742 km/hour at 7.0 on 07/25 (time:7:00)
Distance: Mars >> Sun per theskylive.com: 249,124,458 km [22.0 km/s] Difference is -018007 <= 0680 km/hour at 9.5 on 07/24 (time:9:30)
Next up: HIP 49140 Magnitude 10.01 above path Day 0 about 6 hours ahead.
HIP 49002 Magnitude 10.50 is directly in the path and about 15 hours ahead. On Day 1 49002 is exactly 11 hours behind.
There are two Mini-Boomers in the view today.
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 372,762,783
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 164 is Tuesday 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.
