A gnomon is atop the large rock in the foreground. The gnomon is a stadia rod mounted on a tripod, and serves as an indicator of the gravitational vector and provides accurate vertical reference and calibrated length for determining size and position of objects in near-field photographs. The color scale of blue, orange and green is used to accurately determine color for photography. The rod of it is 18 inches long. The scoop Dr. Schmitt is using is 11 3/4 inches long and is attached to a tool extension which adds a potential 30 inches of length to the scoop. The pan portion, obscured in this view, has a flat bottom, flanged on both sides with a partial cover on the top. It is used to retrieve sand, dust and lunar samples too small for the tongs, another geological tool used by the astronauts. The pan and the adjusting mechanism are made of stainless steel and the handle is made of aluminum. Within the foreground of this scene, three lunar samples were taken--numbers 75060, 75075 and 75080. Astronaut Eugene A.

Bean collected several rocks and samples of finer lunar matter during their Apollo 12 lunar landing mission extravehicular activity (EVA). This particular sample was picked up during the second space walk (EVA) on Nov. 20, 1969. It is a typically fine-grained crystalline rock with a concentration of holes on the left part of the exposed side. These holes are called vesicles and have been identified as gas bubbles formed during the crystallization of the rock. Several glass-lined pits can be seen on the surface of the rock.

S72-56362 (27 Dec. 1972) --- Scientist-astronaut Harrison H. "Jack" Schmitt (facing camera), Apollo 17 lunar module pilot, was one of the first to look at the sample of "orange" soil which was brought back from the Taurus-Littrow landing site by the Apollo 17 crewmen. Schmitt discovered the material at Shorty Crater during the second Apollo 17 extravehicular activity (EVA). The "orange" sample, which was opened Wednesday, Dec. 27, 1972, is in the bag on a weighing platform in the sealed nitrogen cabinet in the upstairs processing line in the Lunar Receiving Laboratory at the Manned Spacecraft Center. Just before, the sample was removed from one of the bolt-top cans visible to the left in the cabinet. The first reaction of Schmitt was "It doesn't look the same." Most of the geologists and staff viewing the sample agreed that it was more tan and brown than orange. Closer comparison with color charts showed that the sample had a definite orange cast, according the MSC geology branch Chief William Phinney. After closer investigation and sieving, it was discovered that the orange color was caused by very fine spheres and fragments of orange glass in the midst of darker colored, larger grain material. Earlier in the day the "orange" soil was taken from the Apollo Lunar Sample Return Container No. 2 and placed in the bolt-top can (as was all the material in the ALSRC "rock box").

Backdropped by a sunrise, the newly installed Materials International Space Station Experiment (MISSE) is visible on this image. MISSE would expose 750 material samples for about 18 months and collect information on how different materials weather the space environment. The objective of MISSE is to develop early, low-cost, non-intrusive opportunities to conduct critical space exposure tests of space materials and components plarned for use on future spacecraft. The experiment was the first externally mounted experiment conducted on the International Space Station (ISS) and was installed on the outside of the ISS Quest Airlock during extravehicular activity (EVA) of the STS-105 mission. MISSE was launched on August 10, 2001 aboard the Space Shuttle Orbiter Discovery.

S73-15171 (4 Jan. 1973) --- These orange glass spheres and fragments are the finest particles ever brought back from the moon. Ranging in size from 20 to 45 microns (about 1/1000 of an inch) the particles are magnified 160 times in this photomicrograph made in the Lunar Receiving Laboratory at the Manned Spacecraft Center. The orange soil was brought back from the Taurus-Littrow landing site by the Apollo 17 crewmen. Scientist-astronaut Harrison H. "Jack" Schmitt discovered the orange soil at Shorty Crater during the second Apollo 17 extravehicular activity (EVA). This lunar material is being studied and analyzed by scientists in the LRL. The orange particles in this photomicrograph, which are intermixed with black and black-speckled grains, are about the same size as the particles that compose silt on Earth. Chemical analysis of the orange soil material has shown the sample to be similar to some of the samples brought back from the Apollo 11 (Sea of Tranquility) site several hundred miles to the southwest. Like those samples, it is rich in titanium (8%) and iron oxide (22%). But unlike the Apollo 11 samples, the orange soil is unexplainably rich in zinc ? an anomaly that has scientists in a quandary. This Apollo 17 sample is not high in volatile elements, nor do the minerals contain substantial amounts of water. These would have provided strong evidence of volcanic activity. On the other hand, the lack of agglutinates (rocks made up of a variety of minerals cemented together) indicates that the orange glass is probably not the product of meteorite impact -- strengthening the argument that the glass was produced by volcanic activity.

AS17-146-22294 (13 Dec. 1972) --- Scientist-astronaut Harrison H. Schmitt is photographed working beside a huge boulder at Station 6 (base of North Massif) during the third Apollo 17 extravehicular activity (EVA) at the Taurus-Littrow landing site.

The scoop, a geological hand tool, leans against the rock. This view was exposed by astronaut John W. Young, commander. The two moon-exploring crew men sampled this rock, which got its name because of a permanently shadowed area it protected.

S120-E-007081 (28 Oct. 2007) --- Astronaut Scott Parazynski, STS-120 mission specialist, participates in the second of five scheduled sessions of extravehicular activity (EVA) as construction continues on the International Space Station. During the 6-hour, 33-minute spacewalk Parazynski and astronaut Daniel Tani (out of frame), Expedition 16 flight engineer, worked in tandem to disconnect cables from the P6 truss, allowing it to be removed from the Z1 truss. Tani also visually inspected the station's starboard Solar Alpha Rotary Joint (SARJ) and gathered samples of "shavings" he found under the joint's multi-layer insulation covers. Also the spacewalkers outfitted the Harmony module, mated the power and data grapple fixture and reconfigured connectors on the starboard 1 (S1) truss that will allow the radiator on S1 to be deployed from the ground later.
