Missions to the Outer Planets: Data Visualization
Inspired from my previous data vis of our missions to Mars, I wanted to continue this theme with a visualization of the missions to the outer planets. Originally, I planned to design it similar to the layout of the Mars missions. However, as many of these probes visited multiple planets, I wanted to capture their movement with a new design.
To do this, I began by showcasing the list of missions, and their destinations in a chart on the right of the poster. To add details, I created icons for each type of mission: flybys, orbiters, atmospheric probes, and even a moon lander for Saturn's moon Titan. I then linked these details to the corresponding years the probes reached their destination.
For each mission, I created a different line pattern. These patterns refer to the paths each probe took on its mission to the planets. The innermost circle is the first mission, while subsequent missions are the outer circles. For missions that were a flyby only, the line never fully circles the planet. While orbiter missions are denoted by a full circle around the planet.
Meanwhile, compared to the Earth in the top right corner, each planet is sized to scale, relative to the size of the Earth.
