Today on Mars: 0036/10/02 Monday <<-- Days of the week are ** IN ** alignment with Earth. The next skip day is in November on Earth.

Today on Earth: 2021/10/25 Monday (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: 4 <<== The Astronomical month will increment when longitude reaches 120 degrees

Solar Longitude: 117.4 Sol Number: 253 Change in degrees is +.5
Previous SL: 116.9 Previous Sol:252

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: 241,453,704 km [22.7 km/s] Difference is -132580 <= 5892 km/hour at 7.5 on 10/25 (time:7:30)
Distance: Mars >> Sun per theskylive.com: 241,586,284 km [22.7 km/s] Difference is -134566 <= 5851 km/hour at 9.0 on 10/24 (time:9:00)
Distance: Mars >> Sun per theskylive.com: 241,720,850 km [22.7 km/s] Difference is -156579 <= 5799 km/hour at 10.0 on 10/23 (time:10:00)

Next up: Star TYC 5546-835-1 Magnitude 8.14 well below path Day 1 about 5 hours ahead. RA 13h 38m 40.3s
Next up: Nothing! There are many stars in the field ahead, but note are identified.
Bright Galaxy below path: PGC 48179 Magnitude 12.80 Day 0 about 24 hours ahead. Expecting to see at Mars tomorrow. Day 1 at Mars as expected

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 2021/10/25 388,995,857 (decrease)
Earth Distance 2021/10/24 389,290,262 (decrease)
Earth Distance 2021/10/23 389,564,788 (decrease)

Mars and Earth are moving apart after Conjunction. The two planets were on opposite sides of the Sun. Earth Distance maximum October 2021.

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 21 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 253 is in Month 10 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month extends from Sol 252 through 279. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 09

Sol 253 is Monday in the Proposed Business calendar for Mars.

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 November 8th 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 2021/10/29 387,659,293 (decrease)

Earth Distance 2021/10/27 388,341,085 (decrease)

Mars and Earth are moving apart after Conjunction. The two planets were on opposite sides of the Sun. Earth Distance maximum October 2021.

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 21 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.

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 November 8th 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.
The next cycle will begin on the first Sol after the end of the period of coincidence.

In the past day (or so) TheSkyLive.com has lost synchronization between the object and the background.
Mars is reported at coordinates that are below and to the left of the background view. Reported 2021/11/02
Object information is still reported, but without formatting of numbers, and the km/s value is missing.
A software update may have occurred. The problem was reported to TheSkyLive via their feedback link.

5 galaxies in a lion shaped pattern: PGC 105488 RA 13h 57m 29.9s below path Day 0 about 10 hours ahead - in view on Day 1
Star TYC 5557-1010-1 M10.7 above TYC 557-447.1 M10.17 below path Day 0 about 14 hours ahead - Day 1 in view

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 2021/11/02 386,165,941 (decrease)
Earth Distance 2021/11/01 386,550,345 (decrease)
Earth Distance 2021/10/31 386,906,295 (decrease)

Mars and Earth are moving apart after Conjunction. The two planets were on opposite sides of the Sun. Earth Distance maximum October 2021.

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 21 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 November (estimate: 8th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may not 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.
The next cycle began on the first Sol of the period of coincidence. The alignment of weekdays interval is in the range: (310 - 337)

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 2021/11/06 384,543,954 (decrease)

Earth Distance 2021/11/04 385,362,530 (decrease)

Mars and Earth are moving apart after Conjunction. The two planets were on opposite sides of the Sun. Earth Distance maximum October 2021.

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 21 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 November (estimate: 8th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may not 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.
The next cycle began on the first Sol of the period of coincidence. The alignment of weekdays interval is in the range: (310 - 337)

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 2021/11/10 382,810,178 (decrease)
Earth Distance 2021/11/09 383,219,383 (decrease)
Earth Distance 2021/11/08 383,649,358 (decrease)

Mars and Earth are moving apart after Conjunction. The two planets were on opposite sides of the Sun. Earth Distance maximum October 2021.

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 21 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 December (estimate: 15th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may not 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.
The next cycle began on the first Sol of the period of coincidence. The alignment of weekdays interval is in the range: (310 - 337)

In recent days, the curve has been slowly bending down through horizontal.

Earth Distance 2021/11/14 380,912.715 (decrease)

Mars and Earth are coming closer after Conjunction. The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

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 21 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 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 December (estimate: 15th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may not 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.
The next cycle began on the first Sol of the period of coincidence. The alignment of weekdays interval is in the range: (310 - 337)

Previous SL: 126.8 Previous Sol:272

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.

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.

Observation: The sky view is ** filled ** with objects and very few have been recorded and given identification by humans or their robot assistants

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 2021/11/18 378,916,799 (decrease)
Earth Distance 2021/11/17 379,415,797 (decrease)
Earth Distance 2021/11/16 379,903,415 (decrease)

Mars and Earth are coming closer after Conjunction. The two planets were on opposite sides of the Sun at Earth Distance maximum October 2021.

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 21 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 276 is in Month 10 of a Proposed 24 month calendar. See Post 19 of Holidays topic for a summary.
Month 10 extends from Sol 252 through 279. See post 82 of Holidays topic for current details. <<== There are 28 days in Month 09

Sol 276 is Wednesday in the Proposed Business calendar for Mars.

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 December (estimate: 15th) on Earth. A Skip Day occurs when the longer Mars Sol accumulates 24 Earth hours.
For those who may not 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.
The next cycle began on the first Sol of the period of coincidence. The alignment of weekdays interval is in the range: (310 - 337)
Use Search Term Alignment to find the first day of a period of coincidence.
