|
 | A control network for Triton has been computed using a bundle-type analytical triangulation program. The network contains 105 points that were measured on 57 Voyager 2 pictures. The adjustment contained 1010 observation equations and 382 normal equations and resulted in a standard measurement error of 13.36 microns. We determined coordinates of the control points, the camera orientation angles at the times when the pictures were taken, and Triton's mean radius. ... |

| RAND's Role in the Evolution of Balloon and Satellite Observation Systems and Related U.S. Space Technology |

|
| This report, prepared as part of RAND-sponsored research, was originally intended to commemorate the fortieth anniversary of Project RAND (now Project AIR FORCE), a long-term research effort that began in April 1946 with a study of the utility and feasibility of space satellites. RAND research on space technology continued, for the next two decades, to emphasize the primacy of photoreconnaissance and the communication to earth of remotely sensed data. Without ... |

| Coordinates of Features on the Galilean Satellites, |

|
| One product of the current exploration of the solar system is the publication of maps of those bodies with solid surfaces. These maps show the relative positions of topographic features, one-to-another, and are used as bases for correlating a variety of measurements and pictorial data and for regional geologic mapping. In order to produce a map of a planetary surface, it is necessary to first establish a coordinate system for ... |

|
| Pictures of the four Galilean satellites were taken as the two Voyager spacecraft approached Jupiter during March and July 1979, and nearly full coverage of all the satellites was obtained by each flyby as the satellites rotated in front of the cameras. High-resolution mosaics of the satellites were obtained during the periods of closest encounter. The faceplates of the vidicon cameras have reseaux of 202 points to permit removal of ... |

| The Mariner 9 Primary Control Net of Mars, |
APR 1973 |

| Authors:

|
| A planetwide control net of Mars is being derived photogrammetrically from the television pictures that were returned by Mariner 9. Such a control net is required by cartographers to relate the coordinate system to landmarks and topography. Although the pictures cover the entire Mars surface, there are gaps in the low-resulution coverage. The vidicon camera, which produced the photos used in the control net computations, is a poor instrument for ... |

| SPACE PHOTOGRAPHY AND THE EXPLORATION OF MARS, |
SEP 1969 |
|
| Authors:

|
| The photographic exploration of Mars, and that of all temporally varying planets, is a multi-variable process in which surface resolution, geographic coverage, and observation time are all of importance. Thus, the conception and design of photographic missions is concerned with the balancing of these and other factors against the total photographic data that can be returned from the spacecraft. This paper emphasizes photography as a communication process in which information ... |

| IS ZOND 5 DESIGNED FOR PLANETARY MISSIONS AS WELL AS LUNAR, |
OCT 1968 |
|
| Authors:
Merton E. Davies; Bruce C. Murray; RAND CORP SANTA MONICA CALIF
|
| It is generally considered that Zond 5 is an unmanned precursor of a manned, lunar mission. While we agree with that specific view, we feel there is strong evidence that Zond 5 also is a precursor of unmanned, planetary missions of much greater capability than otherwise believed possible. It is obvious also that a new, larger launch vehicle is now being used for lunar flights than heretofore. Presumably, this is ... |

| PLANETARY CONTAMINATION II: SOVIET AND U. S. PRACTICES AND POLICIES, |

|
| It was concluded that viable terrestrial micro-organisms which are transported to Mars inside solid components in sealed spaces have a low probability of being released to the surface or atmosphere, and if any are released they are not likely to infect the planet. |

| INSPECTION BY SMALL SATELLITES, |

|
| Prospects are presented on the use of inspection satellites for obtaining photographs of the earth. It is suggested that the satellites would disclose military buildups and violations of certain arms control agreements. |

|
| Release of information by the Soviets regarding spacecraft design and intended mission profiles of their Venus 2 and 3 flights makes it possible to discern a consistent pattern in their very large planetary exploration effort. (1) As has been the case with their lunar exploration efforts, the Soviets have placed very great emphasis on an early planetary impact with or without return of significant scientific information. (2) They have utilized ... |
