Stereo images with substantial overlap are acquired from adjacent orbits providing the means to derive Digital Terrain Models (DTMs) and orthoimages. ![]() The LROC system consists of a Wide Angle Camera (WAC) and two identical Narrow Angle Cameras (NACs) and provides global (75 m/pixel) multispectral coverage as well as high-resolution (0.5 m/pixel) monochrome close-up views of the Moon, respectively. During the nominal phase of the Lunar Reconnaissance Orbiter (LRO) mission the Lunar Reconnaissance Orbiter Camera (LROC) acquired images from a near-circular 50 ± 15 km polar orbit. Here, initial results are shown for traverse station 1 (northwest of Steno Crater) as well as the Apollo Lunar Surface Experiment Package (ALSEP) area. At the same time, the camera orientations, North azimuth angles and distances to nearby features of interest were also determined. As a result, we obtained the surface panoramic camera positions to within 50 cm. Angular directions of these features were measured in the panoramic images and fitted to the NAC orthoimage by applying least squares techniques. Key features captured in the Apollo panoramic sequences were identified in LROC NAC orthoimages. We analyzed observations made in Apollo surface photography as well as orthorectified orbital images (0.5 m/pixel) and Digital Terrain Models (DTMs) (1.5 m/pixel and 100 m/pixel) derived from LROC Narrow Angle Camera (NAC) and Wide Angle Camera (WAC) images. In particular, the positions from where the Apollo 17 astronauts recorded panoramic image series, at the so-called “traverse stations”, were precisely determined for traverse path reconstruction. © 2022 All rights reserved.Newly acquired high resolution Lunar Reconnaissance Orbiter Camera (LROC) images allow accurate determination of the coordinates of Apollo hardware, sampling stations, and photographic viewpoints.

There, the astronauts collected some hardware from the unmanned Surveyor spacecraft, which had landed two years earlier. In the second moon walk, Conrad and Bean set out from the descent stage and looped around Head crater, visiting Bench crater and Sharp crater, then headed east and north to the landing site of Surveyor 3. Though the cables are much too small to be seen directly, they show up because the material they are made from reflects light very well. These instruments are probably (left) the Suprathermal Ion Detector Experiment, or SIDE, which studied positively charged particles near the moon's surface, and (right) the Lunar Surface Magnetometer, or LSM, which looked for variations in the moon's magnetic field over time these two instruments had the longest cables running from the central station. ![]() One of the details visible in this image is a bright L-shape that marks the locations of cables running from ALSEP's central station to two of its instruments. ![]()
