On Monday, Apr. 23, 1962, the Ranger 4 launched into space. Its mission was a part of NASA's unmanned Ranger program, which was created to get the first close-up images of the Moon's surface.
The Ranger spacecraft was developed to capture images of the Moon's surface and transmit them to Earth and then explode upon lunar impact.

Ranger 1 launched in Aug. of 1961 and Ranger 2 launched in Nov. of the same year. They both failed during the launch. Ranger 3 launched on Jan. 26, 1962, and missed the Moon.
Ranger 4's mission is not considered "successful," but it did capture some footage of the Moon's surface, and it was the United State's first spacecraft to reach another celestial body.
The mission failed because a computer onboard malfunctioned and didn't deploy the solar panels and navigation systems. The spacecraft ended up crashing on the far side of the Moon and did not return any scientific data to Earth.
Ranger 7 was the first successful mission, launching on Jul. 28, 1964. It transmitted images of the Moon's surface to Earth.

There were two more Ranger missions after the 7, and they were both successful. Ranger 9 was the program's final mission which launched in Mar. 1965.
