Lick (crater)
Lick is a lunar impact crater that has been flooded with basaltic lava. This crater was named in memory of James Lick, a Californian philanthropist. The north rim is attached to the smaller, bowl-shaped crater Greaves. Lick lies on the southwest edge of Mare Crisium. Its rim is broken at the north and south ends, and the southwest rim is attached to the crater remnant Lick A. There is a small, flooded crater within the southern part of Lick's inner floor, and several tiny craters mark the interior surface. A small, unnamed crater at the east rim has a bright ray system A ray system comprises radial streaks of fine ''ejecta'' thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter .... Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lick. ...

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the scientific instrument module (SIM) bay of the service module. This suite of instruments col ...
