The reduction of the National Aeronautics and Space Administration plates at the New Mexico University
A method of reducing GEOS satellite plates is described. The catalog positions of stars, whose images were measured, are updated to the time of the photographic observation. The plate constants are used to compute the positions of the seven (or fewer) flashing light images which were measured. There are corrected for refraction, parallax, and radial and decentering lens distortions. With sidereally tracking cameras, the exterior orientation is further corrected to the time of the particular flash, and the change of refraction with time is allowed for. First and second differences and standard deviations and covariances for the flashing light images are developed as a measure of accuracy.

Plans for a standard region for long focus astrographs
The construction of a catalog of precise star positions in the region of Praesepe is proposed. A list of the 408 stars to be included is given. The program stars were chosen on the basis of their position, magnitude and color, and the availability of accurate early epoch positions. The present status of the project is noted.

The overlap methods
The different methods of reducing measurements on photographic plates by the overlap methods are compared. An attempt is made to distinguish the methods accepted by most astronomers from those not generally agreed upon and from those that are still being studied. Questions examined are: organization of future works, improvement of AGK2 and AGK3, and solutions for the astrographic catalog, as well as considerations of some empirical methods.

Apollo 11 photography 70-mm, 16-mm, and 35-mm index
A catalog of photographs taken during the Apollo 11 mission is presented. Photographs were taken with the Hasselblad 70 millimeter camera. Magazine N consists of 141 frames of color film. The major number of frames are of the translunar phase of the mission, with photographs of the earth, capsule interiors, and operational photographs. The last 28 frames of the magazine contain photographs of the lunar surface.

Data user's note: Mariner 6 and 7 photographic data (NSSDC ID no. 69-014A-01 and 69-030A-01
The availability and assistance in the use of the complete set of Mariner 6 and 7 (1969 14A and 1969 20A) pictorial data are announced. The announcement describes the photographic mission of these Mariner spacecrafts, the television camera system, and the photographs that are available from the National Space Data Center. Two appendixes are included: one is a photographic catalog of all enhanced photographs, designated the maximum discriminability photographs; the other is a series of computer produced graphics that are useful in detailed analysis of the photographs.

Quarantine document system indexing procedure
The Quarantine Document System (QDS) is described including the indexing procedures and thesaurus of indexing terms. The QDS consists of these functional elements: acquisition, cataloging, indexing, storage, and retrieval. A complete listing of the collection, and the thesaurus are included.

An automated system for the alignment of large area modular solar simulators
A real-time optical alignment and diagnostic system is being assembled for installation at the Space Environment Simulation Laboratory. This system will be used to measure and analyze the performance of optical components, assemblies, and full modules. This information, in turn, is used to align assemblies and modules. The system capability includes such functions as the generation and updating of a catalog, which serves as permanent record, in addition to providing the capability to predict in-chamber performance of optics combinations before they are mounted in the chamber.

Advanced airbreathing engine lubricants study with a tetraester fluid and a synthetic paraffinic oil at 492 K (425 F)
Groups of 120-mm-bore angular-contact ball bearings made from AISI M-50 steel were fatigue tested with a tetraester and a synthetic paraffinic oil at a bearing temperature of 492 K (425 F) in an air environment. Bearing life exceeded AFBMA-predicted (catalog) life by factors in excess of 4 and 10 for the tetraester and synthetic paraffinic fluids, respectively. The final viscosities after 500 hours of operation were 14 and 6 times the initial values, respectively. During the same time period, when the test oil is replaced at a rate approximating the replenishment rate in actual commerical engine usage, no significant increase in lubricant viscosity with time was observed.

Electronic scene generator expansion system
The design, fabrication, and installation of additions and modifications to the electronic scene generator located at the NASA Manned Spacecraft Center, Houston, Texas, are described. The equipment delivered was incorporated into the electronic scene generator to enhance its capabilities by providing: (1) additional source computer interfaces; (2) additional edges thereby allowing more detailed scenes; (3) the ability to share edges to effect economies in complex scenes; (4) the ability to use edges without the constraints of a configuration catalog; and (5) the simplified implementation of new environments and environment modifications.

High Energy Astronomy Observatory star tracker search program
The development of a control system to accommodate the scientific payload of the High Energy Astronomy Observatory (HEAO) is discussed. One of the critical elements of the system is the star tracker subsystem, which defines an accurate three-axis attitude reference. A digital computer program has been developed to evaluate the ability of a particular star tracker configuration to meet the requirements for attitude reference at various vehicle orientations. Used in conjuction with an adequate star catalog, the computer program provides information on availability of stars for each tracker and on the ability of the system to maintain three-axis attitude reference throughout a representative sequence of vehicle orientations.

Documentation of Apollo 15 samples
A catalog is presented of the documentation of Apollo 15 samples using photographs and verbal descriptions returned from the lunar surface. Almost all of the Apollo 15 samples were correlated with lunar surface photographs, descriptions, and traverse locations. Where possible, the lunar orientations of rock samples were reconstructed in the lunar receiving laboratory, using a collimated light source to reproduce illumination and shadow characteristics of the same samples shown in lunar photographs. In several cases, samples were not recognized in lunar surface photographs, and their approximate locations are known only by association with numbered sample bags used during their collection. Tables, photographs, and maps included in this report are designed to aid in the understanding of the lunar setting of the Apollo 15 samples.

Documentation and environment of the Apollo 16 samples: A preliminary report
A catalog which is a working document that shows the locations from which samples were collected during the Apollo 16 mission, and that provides a descriptive geologic context for each sample is presented. It is a compilation of notes from work in progress, and supersedes an earlier report prepared by the Apollo Lunar Geology Investigation Team. The information was obtained from the Air-to-Ground transcript from the astronaut crew, from lunar surface television, from 60 mm Hasselblad camera photographs, and from available LRL mugshot photographs of the samples. The sample descriptions are based on these sources of data.

The intrinsic values and color excesses of (B-V) for 115 F-K supergiants
Color excesses in B-V are determined indirectly from a study of Stromgren's b-y color for a sample of F0 - K5 supergiants. The resulting E(B-V)'s are estimated to have an expected precision of + or - 0.05. With the calculated color excesses and the observed values of B-V given in various catalogs, the run of B-V with spectral type is obtained. This B-V/(spectral type) relationship is compared with those found previously by other investigators.

New astronomy space experiments with television scanning.
Application of data from the Celescope Catalog of Ultraviolet Observations to various problems of stellar and interstellar astrophysics. These include refinements in the incorporation of line blanketing in theoretical stellar-atmosphere models, variations in the law of interstellar extinction from one region of the sky to another, and selection and identification of various types of peculiar stars for further investigation. In addition, the data were analyzed to determine the photometric and astrometric accuracy of the Celescope equipment.
