    MR. MOONLIGHT - BEATLES
    The Beatles- Mr Moonlight - YouTube

    In 1981 I used maps to identify the moon's prominent features. The dark maria are lava plains. Lava flowed from the moon's interior when impacts were hard enough. Five maria combine to form a foot with three toes: Tranquillity, Serenity, Crises, Fertility and Nectar.

    There are not many lava plains on the far side of the moon. The crust is thicker on the far side, so it did not break and flood the lowlands with lava.

    The moon is geologically dead. If a meteor hits, the crater is more or less permanent. There are some interesting craters. Aristarchus is the brightest. Plato is the darkest. Copernicus, Aristarchus, Kepler and Grimaldi form a Y-shape. Tycho in the south is the youngest crater. Young craters have rays extending from them. These rays are stuff that was thrown out. Craters have central peaks, caused by the ground bouncing back. The Apennine mountains rise 20,000 feet.

    Earthshine is Earth lighting up the lunar night. It is sunlight bouncing off the earth, hitting the moon and coming back to our eyes. Earthshine is seen during the moon's crescent phases when the moon is nearly in line with the sun and the earth. The horns of the moon always point away from the sun.

    The moon appears to wax and wane in its monthly orbit. Phases of the moon are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. The new moon is "no moon" because the side reflecting the sun is turned away from us.

    First quarter is lit on the right. Last quarter is lit on the left. Quarter phases are a quarter of the cycle, 90 degrees, from the sun in either direction.

    A blue moon is a second full moon in a calendar month. Blue moons are not that rare. They occur once every 2.7 years.

    Until recently it was thought that the earth and moon formed at the same time. It now appears that the moon came into existence when an asteroid crashed into the earth and ripped part of it away. This accounts for the moon not having a metal core. Old theories are earth-based. New theories are space-based.

    The earth slowed the moon's spin until it keeps one side to us. The moon has two weeks of daylight and two weeks of night. There is no such thing as a "dark side" because the side we never see gets two weeks of light each month.

    The moon is 240,000 miles from Earth. At our doorstep! If we drove around the world 10 times, we could be on the moon.

    The moon causes the tides in our oceans. It tugs at our atmosphere as well, but we are so deep in the atmosphere that we are unaware of it.

    In March, 1960, I saw a total lunar eclipse. The moon took on a dark, copper hue. It remained visible because sunlight was refracted, or bent, onto it by the earth's atmosphere.

    The earth casts a shadow into space. A lunar eclipse occurs when the moon passes through this shadow. Usually the moon passes above or below the shadow. A lunar eclipse can only occur during a full moon because the sun, earth and moon have to line up.

    Earth's shadow has two parts. The umbra is the dark inner cone. The penumbra is the lighter part around it.
    "Umbra" is Latin for shadow. During totality, the moon is completely inside the umbra.

    In February, 1979, I saw a partial solar eclipse in Nashville. It was subtle. Had I not known it was going on, I would not have suspected anything out of the ordinary.

    During a solar eclipse, the moon passes between the earth and sun. Solar eclipses are more fleeting than lunar eclipses because of the relative sizes of the shadows cast by the earth and moon.

    The sky is blue because air reflects light. The sky on the moon is black because there is no air. The only color is the blue earth in the sky. From the moon the earth is stationary but goes through phases.

    The temperature of the moon's surface varies 500 degrees, from 225 to -275.

    Minerals in the moon rocks vary somewhat from those on Earth. There were no fossils in the moon rocks. Life began in the sea, and the moon has never had water.

    American astronauts went to the moon six times between 1969 and 1972. 12 men walked on its surface. Neil Armstrong was the first. He made a mistake when he delivered his prepared statement. He said, "One small step for man, one giant leap for mankind." He meant to say, "One small step for "a" man."

    Apollo 11 landed in the Sea of Tranquillity.

    Weirdos claim that the moon landings were fake. They point to the picture of the American flag supposedly blowing in the wind as proof. Of course, there is no wind on the moon. Actually a horizontal bar was attached to the top of the flag to keep it from going limp. I am not sure if these people are crazy, stupid or making a joke. I debated Bart Sibrel in the parking lot of a karaoke bar in Nashville. Bart was convinced that we never went to the moon. It came out in the national news that he approached Buzz Aldrin (second man on the moon) in California and tried to force him to swear on a Bible that the moon landings were real. Buzz punched him in the jaw! Bart tried to sue, but the Los Angeles County District Attorney refused to file charges.

    I had never before heard that tune by The Beatles, Jim, and you have compiled a lot of interesting details about the moon in one post, so I thank you for it.

    The full moon will be rising while I am sleeping prior to graveyard shift and it will be high enough by midnight that I won't experience that 'Harvest Moon' scale of size when the moon is close to the horizon but it will light my way around the yard while I am doing midnight stables and feeding the horses.

    Jim Colyer,

    Very nice summary, I enjoyed reading it.

    ........and the moon has never had water.
    One correction: Although we do not know of much water on the moon, there is some. According to evidence, there is probably some water ice at the poles of the moon in craters where sunlight can never reach, probably carried there by comets or asteroids after the moons formation. The crust and interior of the moon is probably made up from material of the early Earth, as you pointed out. Even in an early collision with a primordial Earth that probably created the moon, much of the moon would therefore be comprised of material from the Earth's early surface which may also have included much water. Any possible water soon would have disappeared from the moon's surface, and maybe much from the crust as it volcanically out-gassed. Still I would expect if this lunar material came from the early Earth's surface, it would not seem unlikely to someday find deep ice or aquifers within the moon's crust, even though any water conceivably too deep within the moon's crust would probably be beyond economic value.

    Underground water reservoirs, water tables, or lakes conceivably might still exist within drilling distances from the surface. It is not impossible that even microbial life from the early Earth could exist within or near such possible underground aquifers. The extreme temperature variations on the moon's surface would probably be very moderate like the Earth within its crust. Even pockets or caverns could include CO2 or SO2 from out-gassing, which might help sustain possible microbial life within or adjacent to water.

    Mr. Moonlight was on The Beatles 65 album. Good to know someone is looking at the moon besides me.

    Autumn burning without a permit required begins October 1st in the Yukon. Yesterday was too dry and windy for me to start this project even though it was my day off. Late afternoon saw the winds shift to the north and a light ground cover of snow ensued and quite cold overnight temperatures judging by the more than 1 inch thick ice on the 5 gallon pails of water that I had set up near to the burning pit.

    This morning dawned crisp and calm and I lit the fire around 8:30 a.m. after having a couple of cups of coffee and climbing into my insulated jeans, snow boots, layered tops and work parka.

    The moon, just past full, is hanging at about 30 degrees on the western horizon while the sun is just climbing over the ridge to the east. A perfect day for burning.

    Love that burning without a permit that you can do legally out in the country. Kind of a firebug myself For colonies on the moon someday, they will probably find ways to recycle waste and trash rather than burying it or burning it and waste manufactured oxygen and fuel.

    Yup, here's a list. The highest mountain appears to be about 4.7 Km in height, while the tallest on Earth is about 8.8 Km high.

    I'm sorry, but a reference to a popular song followed a regurgitated list of facts doth not a discussion make.

    why is this thread here?

    The same could be asked about many threads on this forum. This thread was started just prior to the autumn 'harvest moon' which is usually one of the most visually spectacular showings of the moon annually.

    Here's more evidence for water on the moon. A little trapped within silica glass beadlets within surface sand and rocks, thought to be from earlier meteor bombardment or somehow from protons in the solar wind, good news for future potential manufacturing of water from surface materials on the moon.

    The investigators found that a large percentage of this glass contained traces of wetness — between 200 and 300 parts per million of water and the molecule hydroxyl, which is much like water, save that each of its molecules possesses just one hydrogen atom, not two.

    Interesting link you posted, forrest noble. The cost of transporting water to the moon is precisely the kind of trivia that strikes interest with me as a lot of my work involves nummerical detail and analysis. As example, I still wonder how we can transport bottled water 1300 miles and sell it as cheaply as we do. I'm sure we sell it below cost and that the cost is spread across the whole corporation. It seems insane when we have some of the best municipal water in the country (subjective input from friends who used to work in water resources) and we also have a bottled water supplier of excellent spring water. Though this data seems contradictory, it must be related to human psychology.

    For the present, the cost of bottled water on the moon will definitely keep the population density low.

    The following from your link.




    SPACE.com reader George Garcia sent in his photo of the September 2012 harvest moon taken on Sept. 29, 2012, in Montebello, CA.

    Glass beads within moon rocks suggest that water seen on the lunar surface originates from the solar wind, researchers say.
    These findings suggest that other airless bodies in the solar system may also possess water on their surfaces, investigators added.
    Arguments raged for years as to whether the moon harbored frozen water or not. Recent findings confirmed that water does wet the moon, although its surface remains drier than any desert on Earth.


    "With the cost of $25,000 for taking one pint of water to the moon, it is essential that we develop processes of producing water from the materials on the moon," said the study's lead author, Yang Liu, at the University of Tennessee at Knoxville. "This is paramount to human settlement of the moon in the near future."
    Text in blue, my emphasis.
