This is my build of the card-paper model of the Space Craft™ International Voyager spacecraft, representing both Voyager 1 (launched September 5, 1977) and Voyager 2 (launched August 20, 1977).

From the brochure included with the model: "The twin unmanned Voyagers were lanuched separately late in 1977 in time to take advantage of a rare alignment of the outer planets. By using the gravity and orbital speed of the outer planets to help accelerate the spacecraft, it was possible to save fuel and make a 'grand tour' of the outer solar system in a reasonable length of time."

Image: This view shows the main components of the spacecraft (from left): Radioisotope Thermoelectric Generators (RTGs), Magnetometer Boom, High-Gain Antenna, Sun Sensor, Spacecraft Bus, Propellent Tank, Science Boom, and Scan Platform.

Image: A close-up of the RTGs. Note the Plume Shield at the end of the boom.

Image: The inboard end of the Magnetometer Boom.

Image: A close-up of the base of the Magnetometer Boom showing a toothpick used to reinforce the base.

Image: The High-Gain and Low-Gain Antennas. Note the cut-out for the Sun Sensor.

Image: Between the High-Gain Antenna Reflector Dish and the Spacecraft Bus can be seen the Propellent Tank, and to its right the Canopus Star Tracker.

Image: A close-up of the gold "Record of Earth," containing pictures and sounds describing life on Earth, that each Voyager carried.

Image: A close-up of the Calibration Target Plate, used (among othe purposes) for image calibration.

Image: A close-up of the Science Boom showing the Scan Platform with its five optical, remote-sensing instruments. On the boom itself are instruments for measuring plasma, cosmic rays, and low energy charged particles.
