ra9_b001.jpgThe Moon from Ranger-9: Alphonsus Crater (4)54 visiteCaption NASA:"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)".MareKromium

ra8_p020.jpgThe Moon from Ranger-8: Mare Tranquillitatis (9)54 visiteCaption NASA:"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" before impact, from a distance of 1,09 Km. The image is about 140 mt across. Image P1 was taken 0,689" before impact from 1,52 Km and is 60 mt across. Image P2 was taken 0,289" prior to impact from 640 mt. The frame is 30 mt across. North is up on all images. (Ranger 8, P020)".MareKromium

ra8_b001.jpgThe Moon from Ranger-8: Mare Tranquillitatis (4)55 visiteCaption NASA:"The first image taken by the Ranger 8 camera B on 20 February 1965 shows the 164 Km diameter Ptolemaeus Crater, top center, and below it Alphonsus Crater (diameter 108 Km). The Davy Crater Chain can be seen immediately to the right of the left-middle reticle mark as a dotted white line extending S-WW to N-EE. The picture was taken 23 minutes before impact from a range of 2545 Km.
The image is about 360 Km across and North is up. Ranger 8 was the second successful lunar impact mission in the series (Ranger 8, B001)".MareKromium

ra8_b045.jpgThe Moon from Ranger-8: Mare Tranquillitatis (5)55 visiteCaption NASA:"Ranger 8 image of the Mare Tranquillitatis (Sea of Tranquillity) area of the Moon taken from 511 Km about 4 minutes before surface impact. The 30 Km diameter Sabine crater is at upper left. Note the two linear features at the center of the frame and rugged region at the bottom.
The frame is about 95 Km across and North is up.
The Apollo 11 Landing Site is about 30 Km to the right of this area (Ranger 8, B045)".MareKromium

ra7_p200.jpgThe Moon from Ranger-7: Mare Cognitum (9)55 visiteCaption NASA:"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" before impact from an altitude of 1070 and 519 mt, 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 mt 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)".MareKromium

ra7_a100.jpgThe Moon from Ranger-7: Mare Cognitum (2)55 visiteThe Ranger series was the first U.S. attempt to obtain close-up images of the Lunar Surface.
The Ranger spacecraft were designed to fly straight down towards the Moon and send images back until the moment of impact.
Ranger 7 impacted in a "mare terrain", modified by crater rays. Ranger 8 also impacted in mare terrain, but this area contained a complex system of ridges.
Ranger 9 impacted in a large crater located in the Lunar Highlands.MareKromium

ra8_a001.jpgThe Moon from Ranger-8: Mare Tranquillitatis (1)56 visiteCaption NASA:"First full-frame image of the Moon taken by the Ranger 8 camera A from a distance of 2573 Km. The image was taken on 20 Feb. 1965 at 09:34 UT with the spacecraft at an altitude of 2510 Km. The central reticle is at 10,65° South Latitude, 22,4° West Longitude, in the Mare Cognitum area of the Moon. North is up, and the picture extends 1200 Km across, from about 5° North to 30° South Lat. and from 5° West to 45° West Longitude. The craters Campanus and Mercator are visible at the bottom center. Gassandi crater (101 Km diameter) is the bright circle near the edge of the frame at 8:00. The Apollo 12 Landing Site is near top center and Apollo 14 slightly to the right of that (Ranger 8, A001)".MareKromium
