America Hits the Moon!

America Hits the Moon! On Sept. 13, 1959 the Soviet Union crash landed the Luna 2 probe onto the Moon - the first thing from Earth to contact another planet. The US followed with a crash onto the lunar surface on April 26, 1962, 42 years ago today. Our Ranger 4 probe was supposed to crash land on the nearside of the Moon, taking images all the way to the surface. But an equipment failure 10 hours into the mission resulted in the spacecraft hitting the lunar farside at 229.3 degrees E, 15.5 degrees S at 9600 km/hr. The yellow arrow on the image above (from the Lunar & Planetary Institute online Lunar Orbiter Atlas of the Moon) shows where Ranger 4 is thought to have hit near the crater Ioffe. This Lunar Orbiter V image is the best view extant of this area, but the horizontal black line/defect shows that there is still a great need for high quality imaging of the farside! Also, did you notice that the red arc marking the southern end of the Hertzsprung impact basin is in the wrong place? The basin's rim is about 0.5" (on my monitor) to the south of the red arc.
