Highly vesiculated basalts have been found on the Moon as well as Earth (slide #21). In 1971 the Apollo 15 mission to Hadley Rille (26°06'N, 3°39'E) returned sample 15556, which has a mass of 1538 grams. This basalt was returned from station 9A, about 60 meters from the rim of Hadley Rille (slide #12). Basaltic lavas from this chemical group at the Apollo 15 landing site formed about 3.3 billion years ago. Scale (in centimeters) is given on the bar at the top of the image.
