This will be an excellent opportunity for lunar researchers to compare upcoming lunar imagery with the 1966 enhanced data. The Moon is not a dead world as once believed. Moonquakes, transient lunar phenomena (possibly outgassing of subterranean gases such as hydrogen), plus some suspected, albeit limited, volcanic activity (such as suspected geological surface changes observed at the "Cobra Head" on the Moon's Aristarchus plateau) should keep graduate and doctoral candidates busy for a few years to come. A really fine recent scholarly book on the topic of the history of lunar geology--with background on NASA's Ranger and Lunar Orbiter programs--is "Inconstant Moon: Discovery and Controversy on the Way to the Moon" by Louis Varricchio.

I remember as a young woman seeing the picture of the earthrise and having tears in my eyes at the wonder and beauty. Thank you for this project, I am so glad that the team is working on saving this data for the younger generation. I can't wait to share the wonder with my grandsons.
