This ...Mare Tranquilitas – meaning “peaceful sea”. This was the site of the first lunar landing when Apollo 11 touched down in July of 1969. The Mare were formed as impact generated basaltic magma flooded the surface, filling the impact craters. The impacts and outflowing of basalt happened between 4.0 and 4.4 billion years ago. (If forced, I’d guess 4.2 billion) The dark, ferromagnesian-rich silicates in the basalt make a distinct contrast with the light colored, ferromagnesian-poor silicates of the anorthosite that forms the lunar highlands. If you think of the moon as the face of a clock, draw a line from the center to the 1:00 position. The line crosses what I think is the sea of tranquility. If that isn’t it, draw a line from the center to the 11:00 position and that mare would be my second guess. I’ve tapped out my memory and refuse to cheat and Google it. Feel free to correct my mistakes.
