rocket launch Cape Canaveral Launch Complex 12

{"selectable":false,"width":"1000px","zoomMin":100000000000}

Frameless

Altitude: 3.6 miles. Area: 1.8 miles on a side. Smallest Visible Crater: 30 feet in diameter; 1 feet deep. Features: Angular rock mass in crater at upper left. Preliminary study indicates the mass to be several separate chunks.

Altitude: 11 miles. Area: 5.5 miles on a side. Smallest Visible Crater: About 45 feet in diameter. Features: Crater near upper left of area outlined in white.

Altitude: 34 miles. Area: 16 miles on a side. Smallest Visible Crater: About 150 feet in diameter. Features: Greater resolution of craters in outlying ray of Tycho.

Altitude: 85 miles. Area: 41 miles on a side. Smallest Visible Crater: About 500 feet in diameter. Features: Cluster of secondary craters in part of a ray of the Crater Tycho becomes distinct.

Altitude: 235 miles. Area: 113 miles on a side. Smallest Visible Crater: About 1000 feet in diameter. Feature: Note increase in detail of Bonpland H and its twin crater (to left of Bonpland H).

Diagram illustrates why moon's third quarter is only acceptable time for launching Ranger.

Guericke Crater as seen by Ranger 7

Head-on view of Ranger's six television cameras. The picturesreceived from Ranger are more than twice as good as those received on ordinary home television sets.

Last picture by Ranger VII, taken about 1600 feet above the moon, reveals features as small as 15 inches across. Receiver noise pattern at right results from spacecraft crash on the moon while transmitting.

Low sun LROC NAC (M132963565R) of the Ranger 7 impact site. At low sun angle, the area appears densely cratered [NASA/GSFC/Arizona State University].

Mid-course Maneuver

Photograph of moon (above) outlines aiming point area in Sea of Clouds were Ranger VII landed at 6:25:49 a.m. EDT, July 31. Map (below photograph) shows targeted and actual impact points, which are about 8 miles apart.

Photo taken by Ranger VIl at 3000-foot altitude shows area 100 feet in each side. Note rounded shoulders of secondary craters (see text).

Telecasts by Ranger VII as it plunged toward moon's surface. The area covered by the next photograph is outlined in white. Blacklines, drawn on camera lens,are used for scale references and as an indication of whether picture is distorted.
