A View From Mars

   I was looking at this picture from the other evening I got to thinking about the Rovers on Mars would see if they looked toward the Earth?

   So as you wonder about that question, here is a look at Mars, by NASA, from last century (I love saying that instead of many years ago!), using data from the first Mars Orbiters. Take a simulated fly over the Martian surface above Mariner Valley and the large Martian volcanoes. Appropriately titled “Mars, the Movie”.


   What would Earth look like from the surface of Mars?
Here is a picture of Earth taken by the Rover Curiosity.

   
   
   
   
   Here is what it looks like using Starry Night Pro 8+ software to model the view from the latitude and longitude of the Perseverance Rover landing site in Jezero Crater, (18.4446°N 77.4509°E).
(The viewing location is correct however for depicting the Martian surface my software uses a view at the landing site for the Sojourner Rover.)

Waxing Crescent Moon – Mars Conjunction

   Friday evening March 19th look for the 6.7-day old waxing crescent Moon to be about 3o from the ‘Red Planet’ Mars, and about 5-6o from the reddish star Aldebaran in Taurus the Bull. All three should just barely fit within the field of view of 7×50 binoculars.

A 3-for-1 Moon Event!

               Apogee – Descending Node – Conjunction with the Pleiades
   
Apogee Moon
   Our Moon reaches apogee, (furthest from Earth), for this orbit, on Thursday March 18th. For this apogee the 6.6-day old waxing crescent Moon will be at a distance of 31.77 Earth diameters, 251,841 miles (405,300 km) from the Earth.

Descending Node
   The 6.6-day old waxing crescent Moon crosses the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.

Conjunction with the Pleiades
   The apogee Moon, at nearly first quarter phase, will be above the western horizon and will be within a few degrees from the open star cluster the Pleiades. This should make for a good view with binoculars.


   Does our Moon actually go around the Earth as this graphic shows? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

Mars, the Pleiades and the Hyades

   The planet Mars has been steadily orbiting eastward and is currently moving past the open star cluster the Pleiades. On Wednesday evening March 3rd Mars will be at its closest to the Pleiades coming within about 3-4o from the open star cluster as it passes by.

Moon Meets the Twins


   Tuesday evening February 23rd the 12-day old waxing gibbous Moon will be about 2o from Pollux, one of the two ‘Twin’ stars of the constellation Gemini the Twins. The other brother is Castor, which is about 6o away from the Moon.

February Moon at Ascending Node

   Saturday February 20th the 9-day old waxing gibbous Moon will be crossing the plane of the ecliptic moving north. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit, and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   On the day of the node crossing the 9-day old waxing gibbous Moon will be over the southwestern horizon later during the evening after sunset local time. Watch for the Moon to be about 8o from the reddish star Aldebaran in the open star cluster the Hyades in Taurus the Bull.

   Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

February Moon at Apogee

   Our Moon reaches apogee, (furthest from Earth), for this orbit, on Thursday February 18th. For this apogee the 7.25-day old waxing crescent Moon will be at a distance of 31.70 Earth diameters, 251,282 miles (404,400 km) from the Earth.

   On the date of the apogee Moon the nearly first quarter Moon will be high above the southern horizon and will be within a few degrees from the planet Mars.

The Moon, Mars, and NASA’s Perseverance

   Thursday evening February 18th the 7-day old almost first quarter but still waxing crescent Moon will be about 3o from the ‘Red Planet’ Mars. Despite the -11.75 apparent magnitude of the Moon Mars, with an apparent magnitude of 0.75, will still be visible.

   
   NASA Perseverance is scheduled to land on Mars on 18 February 2021, at around 20 UT or 2 pm CST.

Moon – Uranus Conjunction

   Wednesday evening February 17th the 6-day old waxing crescent Moon will be about 3-4o from the outer and ringed Planet Uranus. While the Moon with an apparent magnitude of -11.5 will certainly be visible, Uranus with an apparent magnitude of 5.81 will not!

Crescent Moon – Neptune Conjunction

   Saturday February 13th the 2-day old thin waxing crescent Moon will be about 2-3o from the outer planet Neptune and about 6-7o to the west from Dwarf Planet Ceres. The Moon will pass by Ceres over the next 24 hours and by about this time tomorrow the Moon will be to the east from Ceres.
   I should point out that Ceres with an apparent magnitude between 8th and 9th and Neptune with an apparent magnitude between 7th and 8th neither will be visible to the unaided eye.
   However when you are looking toward the Moon you will be looking in the direction of these two distant members of our solar system. This graphic shows the position of the Earth, our Moon, Ceres, and Neptune on February 13th. From this perspective objects to the left of the Sun will be seen in the evening skies as the Earth rotates.
