Limited Offer
SCI / Space Craft International has been the only source in the world for affordable scale model kits of real space exploring machines, since 1987. Now we are offering a limited number of beautifully encased, fully assembled scale models. After the prepared Voyagers have been sold, the offer will be withdrawn, in preparation for the next model to be offered in the series. Complete Display in kit form: After each model display has completed its introductory period as part of The Private Museum series, kit forms of the display case and model are planned to become available for more experienced model makers to enjoy. The display Kit packages will, in the future, include the spacecraft scale model parts and instructions, plus all the parts, components, instructions and tips for assembling the acrylic case and mounting the completed scale model inside. Spacecraft and mission fact sheets will also be included with the kit.
Product Description Case: Acrylic case consisting of two black panels and four clear panels, 1/8 inch thick, measuring 12 inches in height, 12 inches in width, and 10 inches in depth. Actual case weight is 3 pounds, 13 ounces. Included maintenance kit comprises a small supply of acrylic polish, soft cotton polishing rag, and instructions. Fact Sheet: The extensive Voyager Spacecraft and Mission Fact Sheet measures 11 inches high, 17 inches wide. One side presents details of the spacecraft in color graphics, while the other side describes the mission, with illustrations. Each of the features listed below is explained on the descriptive graphic. Enclosed scale model: Following is a detailed description of features visible on the model, each of which are described on the included fact sheet: The dish-shaped high-gain antenna is made of high-density polystyrene foam with a spherical surface figure. The spacecraft bus and all remaining components are made of 100% recycled paper card stock which has been lithographed, foil-stamped, and cut by laser to reveal a high level of detail.
The subreflector of the high-gain cassegrain antenna, and the corresponding feed horn on the main reflector; the low-gain "omni" antenna atop the subreflector structure; the attitude-control sun sensor is mounted in its port in the main reflector. Along the rim of the main reflector dish, a metallic gold line represents the magnetometer test coil. The reflector attaches to the spacecraft bus by three pairs of struts. Attached to one pair of struts is a rectangular grey-scale calibration target plate for use by the optical instruments. The spacecraft Bus has a central spherical propellant tank which is represented by two intersecting circles. The Canopus (star) tracker is mounted atop the bus below the Hight Gain Antenna main reflector. Individual thermal-control louvers are illustrated on the outer surfaces of the bays of the spacecraft bus, by means of stamped silver metallic foil. Gold metallic foil illustrates the gold record which on the spacecraft carries messages and information from Earth. Struts extending below the bus represent those struts which attached to the Voyager's propulsion module, jettisonned soon after launch in 1977. The science boom, extending from one side of the spacecraft bus, is a box truss supporting the cosmic ray science instrument, the plasma science instrument, the low-energy charged particle science instrument, and the scan platform containing the optical instruments: two cameras, an infra red interferometer-spectrometer / radiometer, a photopolarimeter, and an ultra violet spectrometer. These optical instruments are represented by intersecting planes to give the impression of 3D components. On the opposite side of the spacecraft from the science boom are two additional booms. In line with the bus is the RTG boom, holding two Radioisotope Thermoelectric Generators, the spacecraft's power supply. These cylindrical components are represented by intersecting planes to provide the impression of 3D components. A plume shield, represented in silver metallic foil on a disc, extends from the end of the RTGs. (During launch, this protected the stowed RTGs from a hot plume from the propulsion module.) The magnetometer boom is the remaining appendage on the same side of the bus as the RTG boom. This long boom is represented faithfully as a delicate trusswork boom of triangular cross section. Made of fiberglass on the spacecraft, laser-cut paper produces a good reproduction on the model. Only half the boom's scale length is included on the model, in order that it may fit into a roughly cubical display case. Both of the high-field magnetometers and both of the low-field magnetometers are indicated on the model. Two 10-meter long wire antennas (a dipole) are shared by the planetary radio astronomy science instrument and the and plasma wave science instrument (PRA/PWS) on the spacecraft. These extend from the model but are truncated at less than scale length where they intersect the case walls. Placard on case reads: "SCALE APPROXIMATELY 1/30. 13-METER LONG MAGNETOMETER BOOM SHOWN AT HALF SCALE LENGTH. 10-METER LONG PRA/PWS ANTENNAS TRUNCATED."
