Surveyor crater is a small crater inOceanus Procellarum on theMoon. The name of the crater was formally adopted by theIAU in 1973.^[1]

On April 20, 1967, theSurveyor 3 spacecraft landed within the crater near the east rim. Surveyor 3 was the third lander of theAmerican uncrewedSurveyor program sent to explore the surface of the Moon.

TheApollo 12 astronautsPete Conrad andAlan Bean landed theLunar Module (LM)Intrepid north of Surveyor crater on November 19, 1969, and eventually walked over to Surveyor 3. During their descent, Surveyor crater was a major landmark, and is the largest crater at the landing site. To the west of Surveyor isHead crater. To the southwest areBench crater andSharp crater (now called Sharp-Apollo). To the south isHalo crater. A distinct crater on the northeast rim is calledBlock crater.

Block crater was described in theApollo 12 Preliminary Science Report:^[3]

At Block Crater, high on the north wall of Surveyor Crater, nearly all the ejected blocks are sharply angular, which suggests that the crater is very young. Many of the blocks clearly show lines of vesicles similar in appearance to vesicular lavas on Earth. The blocks are probably derived from the older, coarse blocky ejecta deposit underlying the rim that resulted from the Surveyor Crater event. The regolith at Block Crater may be a meter or less thick.

Manysamples were collected in and around Surveyor crater.^[4] Samples taken near the LM on the north rim of Surveyor crater include drive tube sample 12026,^[5] and contingency samples 12073 (regolithbreccia)^[6] and 12075 (olivinebasalt).^[7] Soil Sample 12042 was collected on the southwest rim near Halo crater.^[8] Samples 12043 (pigeonite basalt),^[9] 12044 (soil),^[10] 12051 (ilmenite basalt),^[11] and 12054 (glass-coated ilmenite basalt)^[12] were collected on the south rim. Samples 12056,^[13] 12062,^[14] 12063,^[15] 12064^[16] (all ilmenite basalts), and 12065 (pigeonite basalt)^[17] were all likely collected in the interior of the crater near the east rim and northeast of the Surveyor 3 lander. Samples 12045,^[18] 12046,^[19] and 12047^[20] (all ilmenite basalts) were collected at Block crater on the north rim of Surveyor crater.
