The remarkable "X" on the floor of Palmieri
What is very curious about the crossing of both rilles on the floor of Palmieri is the rectangle-shaped depression at the very centre of the "X". Which one of the two rilles was first? Or did they appear simultaneously? Are there much more of these rectangle-shaped depressions on the moon? (created by rille crossings). Another such crossing is the one on the floor of the unnamed crater southwest of De Gasparis.
Nomenclature
Luigi Palmieri (April 22, 1807 - September 9, 1896) was an Italian physicist and meteorologist. Using a seismometer for the detection and measurement of ground tremors, Palmieri was able to detect very slight movements and to predict the eruption of volcanos. Using a modified Peltier electrometer, he researched atmospheric electricity. He developed a modified Morse telegraph. He improved the anemomete and pluviometer.
