Surveyor 3 was the third lander of the Surveyor program that explored the Moon. Launched on April 17, 1967, 

Surveyor 3 landed April 20, 1967 at the Mare Cognitium portion of the Oceanus Procellarum. A total of 6,315 images were transmitted to Earth.

As it was landing, highly reflective rocks confused Surveyor 3's descent radar. The engines failed to cut off at 14 ft (4.3 m) as per the planned flight profile, causing the spacecraft to bounce twice.[1] The first bounce reached an altitude of 35 ft (10 m). The second bounce reached 11 ft (3 m). On the third impact—from an initial altitude of 11 feet (3 m) and velocity of zero which was under the original design target of 14 ft (4.3 m) slowly descending—the spacecraft settled in a soft landing per design intentions.

This mission was the first carrying a surface soil sampling scoop which can be seen on an extendable arm in the images. This was mounted on a motor driven arm and used to dig four trenches. The trenches were up to 7 in (180 mm) deep. Samples from the trenches were placed in front of the spacecraft's television cameras for image transmission back to Earth. When lunar nightfall came on May 3, 1967, the spacecraft was shut down to preserve battery power; upon the next lunar dawn (14 terrestrial days, or approximately 336 hours) the spacecraft could not be reactivated.
 

Surveyor Scoop

This site was subsequently selected for the Apollo 12 manned lunar mission. Several components of the Surveyor were collected and returned to Earth for study of the long term exposure effects of the harsh lunar environment on human artifacts.

It is widely claimed that a common bacterium, Streptococcus mitis, accidentally contaminated the spacecraft's camera prior to launch and survived dormant in this harsh environment for two and a half years, to be detected when Apollo 12 brought the camera back to Earth in 1969 [1]. This claim has been cited as providing credence to the idea of interplanetary panspermia, but more importantly, led NASA to adopt strict abiotic procedures for space probes to prevent contamination of Mars and other bodies suspected of having conditions suitable for life; most dramatically the Galileo spacecraft was deorbited to avoid impacting Europa. However, NASA officials now no longer support this claim (see Reports of Streptococcus mitis on the moon).

Mare Insularum, April 1967

As Surveyor 3 came in for a soft landing on the Moon, one of its thrusters didn't turn off at the proper time; as a result the spacecraft bounced several times before it came to rest at 3.01 S, 336.66 E. The last little bounce produced the imprint above the footpad in the center of this panorama. The first bounce was over the ridge and was not visible to Surveyor's camera. A scoop was used to scuff the soil -- the first use of a robotic arm on another world. The camera took more than 6,300 images. Unfortunately, the images were severely compromised by the presence of dust on the mirror. This panorama was scanned from a photographic print of a hand-assembled mosaic, then digitally reconstructed and cleaned of visual defects by Philip Stooke.

Successful lunar lander (USA)
Launched: April 17, 1967
Lunar landing: April 20, 1967
As Surveyor 3 came in for a soft landing on the Moon one of its thrusters didn't turn off at the proper time and the spacecraft bounced a couple of times before it came to rest in the Ocean of Storms. Onboard the spacecraft, a scoop was used to collect soil samples, and a camera took over 6,300 images.
