37-Ranger7.jpgMare Nubium: the impact of Ranger 783 visiteCaption NASA originale:"The final two images taken by Ranger 7 before its impact on the Moon's Surface. These image were taken by the number 1 and 3 P-channel cameras at 0.39 and 0.19 seconds before impact from an altitude of 1070 and 519 meters, respectively. The pictures are cut off because the spacecraft impacted the surface before completing the transmission. The top image was taken by the P3 camera and the bottom image by P1. The P3 image is about 25 m across. North is at 12:30 for both images. The impact occurred on 31 July 1964 at 13:25:48.82 UT (Ranger 7, CP1002)".

44-Ranger9.jpgPtolemaeus, Alphonsus and Albategnius Crater81 visiteCaption NASA originale:"Ranger 9 B-camera image from 2500 km showing Ptolemaeus, Alphonsus, and Albategnius craters. Ptolemaeus is the large (164 Km diameter) flat-floored crater at the top. Alphonsus, diameter 108 Km, is at lower left and the 114 Km Albategnius crater is at lower right. The terminator runs through the lower corner. Ranger 9 impacted in Alphonsus Crater 18,5 minutes after this image was taken. North is at 12:30 (Ranger 9, B001)".

33-Ranger7.jpgGuericke Crater80 visiteCaption NASA originale:"Ranger 7 B-camera image of Guericke Crater (11.5° S, 14.1° W, diameter 63 Km) taken from a distance of 1335 Km. The dark flat floor of Mare Nubium dominates most of the image, which was taken 8,5 minutes before Ranger 7 impacted the Moon on 31 July 1964. The frame is about 230 Km across and north is at 12:30. The impact site is off the frame to the left (Ranger 7, B100)".

29-Farside-Luna3.jpgThe Far-Side of the Moon from "Luna 3" (the best picture)78 visiteCaption NASA originale:"This view shows the far side at right and the near side making up about one-third of the image at left. The circular dark patch below and left of center is mare Smythii, on the boundary between the near and far sides. Just above this is Mare Marginus. The dark circle at upper right is Mare Moscoviense and at lower right is the crater Tsiolkovskiy with its light central peak. The image is centered at 10° N, 110° E; North is at 11:30 (Luna 3-phc7)".

39-Ranger8.jpgRitter and Sabine Crater, from Ranger 877 visiteCaption NASA originale:"Ranger 8 image of the Moon from 302 km. The image was taken on 20 February 1965 and 9:55 UT, two and a half minutes before the spacecraft impacted on the Lunar Surface. The two large craters at upper center are Ritter (above left) and Sabine, each about 30 Km in diameter. The Apollo 11 landing site is just off the right edge of the image at about 4:00. The image is about 130 Km across and north is up (Ranger 8, A030)".

42-Ranger8.jpgImpact of Ranger 8: the last images77 visiteCaption NASA originale:"Final pictures taken by the Ranger 8 P-camera about 1/2 second before impact. Impact occurred on 20 February 1965 at 9:57:36.256 UT. The images are ordered (clockwise from upper left) P3, P4, P2, P1. Impact occurred before transmission of the image P4 was complete, hence the static over most of the image. The areas shown are in Mare Tranquillitatus (Sea of Tranquillity) about 60 km north of the Apollo 11 landing site. Image P3 was taken 0,489 seconds before impact, from a distance of 1,09 Km. The image is about 140 meters across. Image P1 was taken 0,689 seconds before impact from 1,52 Km and is 60 meters across. Image P2 was taken 0,289 seconds prior to impact from 640 meters. The frame is 30 meters across. North is up on all images (Ranger 8, P020)".

43-Ranger9.jpgMare Nubium panorama from Ranger 975 visiteCaption NASA originale:"The first Ranger 9 image of the Moon, taken with the A camera from a distance of 2378 Km. The image is centered on the Mare Nubium region of the Moon, which extends to the bottom of the image. At upper left is southeastern Oceanus Procellarum. The 2 craters with the central peaks at right are Alphonsus, diameter 108 Km and below it Arzachel, diameter 96 Km. The crater near the center at about 8:00 is 60 Km Bullialdus. The frame is approximately 1050 Km across and north is at 12:30. The final impact point of Ranger 9 is in the Alphonsus Crater, midway between the central peak and rim at about 1:30 (Ranger 9, A001)".

19-Oceanus Procellarum.jpgNorthern Oceanus Procellarum74 visiteCaption NASA originale:"Lunar Orbiter 5 view of a chain of elongated craters and low mounds in northern Oceanus Procellarum on the Moon. The chain continues to the south (down) of this image as a mare ridge. The chain may have been formed by upwelling of material along a line of weakness resulting in extension to form mounds and collapse to from the elongated craters. The crater at the upper left is about 7 Km in diameter (Lunar Orbiter 5, frame M-183)".

25-Farside-Luna3.jpgThe Far-Side of the Moon from "Luna 3"74 visiteCaption NASA originale:"This is the second image returned by Luna 3, taken by the wide-angle lens, it showed the far side of the Moon was very different from the near side, most noticeably in its lack of lunar maria (the dark areas). The right three-quarters of the disk are the far side. The dark spot at upper right is Mare Moscoviense, the dark area at lower left is Mare Smythii. The small dark circle at lower right with the white dot in the center is the crater Tsiolkovskiy and its central peak. The Moon is 3475 Km in diameter and north is up in this image (Luna 3-2)".
