I can publish the map to more people by creating a web-deliverable app. A paper map with 6 large-scale insets? Or a digital multiscale version? The latter. But I also wanted it to provide a focus on the Apollo missions to tie it to the 50 th anniversary of Apollo 11. Well part of what I wanted to create was a single map that allowed people (anyone with a broad interest) to explore the moon and its landscape. What’s its purpose for existing? Paper or digital? Flat or round? Single or multiscale? Plenty of people have made maps of the whole of the moon, or parts of it throughout history, so what’s to be achieved by a new map? You can go and explore, and when you return we’ll dissect it (launch here if you want to see it in a separate window)Įvery mission needs a plan so the first thing to establish is what the map is going to do. These tips should stand you in good-stead.īut first, let’s take a look at the finished app. You may want to have a go at making one yourself, or build a map of a different planetary object (or space station?). All maps are compromises and I’ll share what I had to decide as I embarked upon my mission. In this blog I’ll share some of the decisions that I made in creating my map of the moon, and also outline some of the technical considerations that drove certain decisions. Any excuse to make a map right? But you’ve still got to make the right map, and make it right. Given that I also turned 50 this year (and so did Esri) it seemed a fitting convergence of events. And I wanted to make a map of it to celebrate the 50 th anniversary of the Apollo 11 moon landings, which took place on 20 th July 1969. Our moon is the fifth largest planetary satellite in our solar system and is the only astronomical body that orbits Earth. Learn about the types of full moons here.See what I did? Mashing up the title of a song by The Waterboys with the classic Police hit is a metaphor for the map mashup of the moon I recently created.Interested in learning more about the Moon? Use this tool to see the current Moon phase and to plan ahead for other Moon views. Here’s what the Moon looks like right now from Earth: That means the Moon's cycle is 27 days long. It takes 27 days for the Moon to orbit Earth. The Moon displays these eight phases one after the other as it moves through its cycle each month. □ Waning Crescent: In the Northern Hemisphere, we see the waning crescent phase as a thin crescent of light on the left. It is the opposite half as illuminated in the first quarter moon. □ Third Quarter: We see the third quarter moon as a half moon, too. □ Waning Gibbous: The waning gibbous phase is between a full moon and a half moon. □ Full: We can see the Moon completely illuminated during full moons. □ Waxing Gibbous: The waxing gibbous phase is between a half moon and full moon. □ First Quarter: We see the first quarter phase as a half moon. □ Waxing Crescent: In the Northern Hemisphere, we see the waxing crescent phase as a thin crescent of light on the right. □ New: We cannot see the Moon when it is a new moon. During the new moon, the side facing Earth is dark. At that point, the far side of the Moon is facing the Sun. Eventually, the Moon reaches a point in its orbit when we don’t see any of the Moon illuminated. When we have a full view of the completely illuminated side of the Moon, that phase is known as a full moon.īut following the night of each full moon, as the Moon orbits around Earth, we start to see less of the Moon lit by the Sun. On Earth, our view of the illuminated part of the Moon changes each night, depending on where the Moon is in its orbit, or path, around Earth. The position of the Moon and the Sun during Each of the Moon’s phases and the Moon as it appears from Earth during each phase.
