Description

The Ranger project of the 1960s was a US effort to launch probes directly toward the Moon. The spacecraft were designed to relay pictures and other data as they approached the Moon and finally crash-landed into its surface. A variety of difficulties plagued the first several attempted missions in this series, but the later Rangers were finally a complete success.

Ranger 4 was designed to transmit pictures of the lunar surface to Earth stations during a period of ten minutes prior to impacting on the Moon.

Heritage Consideration

An onboard computer failure caused failure of the deployment of the solar panels and navigation systems; as a result the spacecraft crashed on the far side of the Moon without returning any scientific data.

Description

Ranger 4 was a spacecraft of the Ranger program designed to transmit pictures of the lunar surface to Earth stations during a period of 10 minutes of flight prior to crashing upon the Moon, to rough-land a seismometer capsule on the Moon, to collect gamma-ray data in flight, to study radar reflectivity of the lunar surface, and to continue testing of the Ranger program for development of lunar and interplanetary spacecraft. An onboard computer failure caused failure of the deployment of the solar panels and navigation systems; as a result the spacecraft crashed on the far side of the Moon without returning any scientific data.

Ranger 8: Lunar Impact
The mission of Ranger 8 was to take high-resolution photographs of the Moon before impacting the lunar surface. Ranger 8 impacted the Moon about 15 miles (24 kilometers) from its target in the Sea of Tranquility, the area where Apollo 11 landed July 20, 1969, bringing the first humans to
Ranger 7: Lunar Impact
The mission of Ranger 7 was to take high-resolution photographs of the Moon before impacting the lunar surface. The images taken by Ranger 7 helped scientists conclude the Apollo astronauts could safely land in the smooth mare regions (the "seas") of the Moon.
Ranger 6: Lunar Impact
Ranger 6 was principally designed to transmit high-resolution photographs of the Moon before impacting the lunar surface. The spacecraft carried six television videocon cameras, however, due to a failure of the camera system, no images were returned.
