Title:
Geologic Map of the Aritarchus Region of the Moon by H. J. Moore.
Description:
This is the U.S. Geological Survey's stunning full color geologic map of the Moon's fascinating and mysterious Aristarchus region. Deep in the dark expanse of the Ocean of Storms ('Oceanus Procellarum'), sits Aristarchus Plateau, pocked by Aristarchus Crater, the brightest large formation on the moon, visible to the naked eye on the northwest (or upper left) of the Moon's near side.
This mysterious region is the site of more ‘transient lunar phenomena' than any other on the Moon. Transient lunar phenomena are temporary obscurations, explosions, or color changes on the surface. And then there was the event of 1971. Apollo 15 was passing 110 kilometers above the plateau, when Aristarchus emited a burst of radioactive Radon-222 alpha particles. Selenologists say this was either a coincidental diffusion of gas to the surface, or a discrete explosion. An explosion leaves those with a taste in science fiction (which so often becomes science fact) to wonder: was something under the surface of the Moon attempting to communicate? Or destroy?
Fittingly, this map's rich, veiny colors suggest a fleshy, alien landscape. The map includes two sectional views (from the side) of the area, detailed ‘metadata' explaining the mapmaking methodologies and symbols employed, and an index map showing the area's location on the Moon.
Aristarchus was named after the Greek astronomer Aristarchus of Samos (310-c.230 BC), creator of the first known helio-centric model of the solar system, placing the Sun, not the earth, at the center of the solar system. The crater was so named by the Italian map maker Giovanni Riccioli in his 1651,
The New Algamest,
, in which he named craters after famous astronomers and philosophers. The name became an international standard when it was adopted by the IAU (International Astronomical Union) in 1935.
It is believed that most of the moon's craters were formed approximately 3.9 billion years ago, during a period of intense bombardment in the Inner Solar System. The cratering rate fluctuates as collisions in the asteroid belt send fragment clusters into the Inner Solar System. This map might show hypervelocity impact craters caused by the same cluster of asteroids that, 65 million years ago, caused the extinction of the dinosaurs.
As humans wouldn't land on the moon until 1969, how were we able to map its geology? The map's extraordinarily detailed metadata explains that the cartographers used photos dating back to 1960 (remember the series of Ranger missions in the mid-60's?), and observations from optical and radio telescopes, with relief created by measuring shadows, combined with an assumed sun angle and an assumed base elevation. The geology was arrived at from observing differences in, and layering of, topographical forms, and in varying albedo (amount of reflected sunlight), both of which indicate different underlying materials formed under different processes. Goals of this work included the identification of suitable moon landing locations, and sources of oxygen for possible in establishing a more permanent lunar base.
This map represents a breath-taking leap forward not only in selenography (the study of the moon), begun in the late 1400s, but also in the record of humankind's fearless exploration of the world(s) around and beyond us.
This map would be a great companion piece to the other maps in the
Geologic Atlas of the Moon,
. It would also wonderfully complement early explorers' maps, or any of the plates from Burritt's famous 1856
Atlas to Illustrate the Geography of the Heavens
, one of writer H.P. Lovecraft's most prized possessions.

Condition:
Very Good.
Shipping:
Shipping rates are not negotiable. Items are shipped within three business days of receiving payment. We are happy to consolidate shipping where possible. The following shipping options are available:
1. FedEx Overnight (45 USD). USA Only. Signature Required.
2. FedEx Ground or Home Delivery (15 USD). USA Only. 1 - 10 days. If your address is a P.O. Box and cannot ship FedEx we will ship USPS Priority and, while we ship promptly, recent postal personnel cutbacks mean that delivery may take time. Signature Required.
3. FedEx International or DHL International EXPRESS (45 USD).
4. We can use your FedEx Account.
Customs:
International buyers are responsible for paying duty and taxes on delivery. DHL or FedEx will contact the buyer by telephone to arrange tax payment if it is levied. Duty varies by country and we cannot predict the amount you will be charged. Some countries are duty free, others are not. Typically, a customs duty and/or VAT tax will be assessed on all parcels to continental Europe. Sometimes duty or tax is due in China, but is seems very random. Hong Kong, Singapore, Korea, and Taiwan have never assessed duty on a map we shipped. Maps shipped to the UK should be duty free as educational materials, but from time to time duty of 5% is assessed incorrectly by the UK customs agents.
Insurance:
All shipments are insured privately against loss and damage. All of our shipments require a signature for insurance purposes.
If you have any questions please feel free to email us through eBay.
