Martian Year: 37 Martian Astronomical Month in 12 month format: 11 <<== The Astronomical month will increment when longitude reaches 330 degrees

===
Solar Longitude: 305.2 Sol Number: 571 Change in degrees is +.5 Julian date is: J0037571
Solar Longitude: 304.7 Sol Number: 570 Change in degrees is +.6 Julian date is: J0037570
Gap
Solar Longitude: 303.5 Sol Number: 568 Change in degrees is +.6 Julian date is: J0037568
Solar Longitude: 302.9 Sol Number: 567 Change in degrees is +.6 Julian date is: J0037567
<<#

Note that Solar Longitude measurement varies as a function of location in orbit. Ls 0 is the moment when the Sun appears to transit from one hemisphere to the other. Update from Mars.NASA.gov (The Sun crosses the equator of Mars (Vernal Equinox)). The transition itself is a function of the tilt of an object with respect to the Solar plane. Per squarewidget.com, Hipparchus created the celestial coordinate system we use today.

Note#2: https://theskylive.com/mars-tracker This web site shows the astronomical position of Mars as seen from Earth
Todo: At next Aphelion/Perihelion record the Mars data J00##### (and set Search term)
Perihelion occurred at Ls 251 on Sol 485 – Earth Date 2024/05/08 Next: (estimated) 2026/03/06
Perihelion occurred at Ls 251 on Sol 485 - Earth Date 2022/06/21 Next: (actual) 2024/05/08
Aphelion occurred at--- Ls 071 on Sol 152. Aphelion Earth Dates: Earlier: 2017/10/07, 2015/11/20
Aphelion occurred near Ls 070 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.

Note on data below: The figure quoted after distance is a rate of progress along the orbital path [exact meaning to be determined]
Minus prefix means Mars is approaching the Sun. Plus prefix means Mars is moving away from the Sun.
The figure computed to the right of "Difference" is the rate of change of the distance to Sun. Increasing to Aphelion/Decreasing to Perihelion.

Distance: Mars >> Sun per theskylive.com: 214,335,284 km [25.6 km/s] Difference is +156730 <= +6269 km/hour at 08.0 on 08/04 (time 8:00) (24.0 hours)
Distance: Mars >> Sun per theskylive.com: 214,178,554 km [25.6 km/s] Difference is +158917 <= +6357 km/hour at 08.2 on 08/03 (time 8:00) (24.25 hours)
Gap note above reading was taken at UTC 12:15
Distance: Mars >> Sun per theskylive.com: 213,863,573 km [25.7 km/s] Difference is +154801 <= +6192 km/hour at 08.0 on 08/01 (time 8:00) (24.0 hours)
==*==*==*

Observation: The sky view is ** filled ** with objects and some have been recorded and given identification by humans or their robot assistants
And! ** All ** the location assignments are from the perspective of Earth. The entire catalog needs to be adjusted when inter-stellar travel begins
The work that lies ahead for the astronomical community is daunting - there is work ahead for centuries
2022/01/19 - All current (existing) stellar catalogs are computed with reference to the Earth. Another civilization would use it's planet as reference.
Perhaps a Milky Way frame of reference will become necessary at some point. The Earth is as good a Zero point as any, for humans.

=== Mars is in Regular Movement as seen from Earth. Mars is progressing from lower right to upper left in the view from Earth. Slant 20 degrees.
Next up: Star in path: TYC 1278-379-1 RA 04h 34m 45.0s – Day 0 -
TYC 1277-562-1 RA 04h 31m 41.7s – Day 0 – Day 1 below 10 hours marker

Zoom Out Capability As a general observation ... 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 (Zoom out)
Update 2022/12/08 TheSkyLive.com provides a large view of selected objects: Select [Major Bodies] Then select [Information] in the body of interest
Update 2022/12/08 Scroll down to (body) Position and Finder Charts. Field of view is 50x30 degrees.

Note: The curve of the path of Mars as seen against the background of stars is now a line heading left at a downward angle.
As of 2023/01/11, the curve of the path has returned to regular movement to the left border

Light travel time today is between 13 and 14 minutes. Communications delay would be 26+ minutes round trip.

===
Earth Distance: 2024/08/04 236,250,000 (decreasing)
Earth Distance: 2024/08/03 237,024,000 (decreasing)
Gap
Earth Distance: 2024/08/01 238,370,000 (decreasing)
#>

Light travel in one second is (about) 300,000 kilometers. The distance covered in one minute is about 18,000,000 kilometers. Estimated light times:
1:18, 2:36, 3:54, 4:72, 5:90, 6:108, 7:126, 8:144,9:162,10:180,11:198,12:216,13:234,14:252,15:270,16:288,17:306,18:324,19:342,20:360,21:378,22:396

Maximum Earth-Mars distance is estimated to be 401 million kilometers (both at apogee and opposite vs Sun)
Mars and Earth were in Opposition (Earth center) in December of 2022. The date coincided with a (very rare) occultation of Mars by the Moon.
Mars and Earth were in Conjunction (Sun center) in November of 2023.
Mars and Earth appear to have been as close as they will get in this cycle. 81,454,323 kilometers on J0036644 Time: 4.53 minutes - 9 minutes round trip

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.

Regular movement of Mars as seen from Earth resumed as of 2023/01/13. RA is once again increasing.
According to www.hercampus.com, Retrograde movement began October 30, 2022.
The online solar system display at the link below shows clearly how the Mars movement will occur in months ahead.

This web site offers an online model of the solar system: www.solarsystemscope.com It requires Chrome 57, Firefox 52 or Safari 10.1. Viewed 2022/10/13: Opposition will occur some time in December of 2022. Per earthsky.org, the date is December 8, 2022.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees. <<== The current year on Mars is 37
Per www.planetary.org Year 36 started 2021/02/07 on Earth. Mars Year 37 began 2022/12/27 on Earth.

Days of the Week Alignment:
Days of the week fall behind Earth due to the longer Sol, but they also change 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)
To find the first day of a period of coincidence: Set up: SearchTerm(colon) and (colon)Alignment and J0036* or J0037*
The most recent End-Of-Quarter change occurred: … The search specified above gave 11 pages of results.

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.
