The gringa has reached that age where she critically examines the tiny lines around her eyes and notices the effects of gravity slowly creating those puppet lines around my mouth as my cheeks droop a bit lower every year. And then there’s that little turkey wattle dewlap flap hanging under my chin and drawing attention to my scrawny chicken neck. Despite my flaws, the gringa is not interested in a facelift. Our Moon, however, gets one every so often whether it likes it or not.
Yep, about every 80 thousand years or so the Moon is transformed into something unrecognizable from its former self. Does this amazing facelift happen overnight? No. It experiences its own form of nips and tucks gradually. Every year numerous comets, asteroids and meteors crash into our Moon and create almost 200 new craters.
If you visit NASA’s photo gallery you can find an array of Moon images dating back to 2009 when the Lunar Reconnaissance Orbiter spacecraft began its mission. It has been mapping the Moon’s surface for years. Comparisons of the collection of images that span five years’ worth of work tells the gringa that mapping the Moon will be a never-ending job seeing as how everything is always changing.
An historical super-moon is scheduled to arrive around November 16. Chances are newspapers and cyberworld will be filled with images of our Moon as it appears in 2016. This is the perfect opportunity for a Moon project to see if amateur stargazers can detect any changes. Below are a pair of 2009 images of our Moon you can use for comparison:
