Humans know a lot about space from years of research and scientific discovery, but there is still a lot that is unknown. Our human curiosity and ambition has combined over the years to advance our pursuit the discovery of new astronomical findings. One such ongoing effort is the Voyager Program. Two space probes, Voyager 1 and Voyager 2, were launched in the late 1970s to collect data about our solar system. Voyager 2 was launched from the Kennedy Space Center on August 20, 1977. Voyager 1 was also launched from the Kennedy Space Center 15 days after Voyager 2 on September 5, 1977. The reason for the seemingly backwards numbering is that they weren’t labeled based on launch date but rather by which probe would first make it to the location of its primary mission. Voyager 1 had a primary mission of exploring the inner Jovian planets Jupiter and Saturn, while Voyager 2 had a primary mission of exploring the outer Jovian planets Neptune and Uranus. The two probes have long since completed those original missions, but the Voyager Program has kept them in space to collect additional data, which they are still doing today.

The first question that needs answering is how the probes function. Remember that their mission is not only to collect data, but to also transmit it back to Earth. In order for a successful relay of the data, the probes have parabolic antennas which need to be oriented in the direction of Earth. Because these probes are traveling through space on their own,…
