The top 10 neighbors split into two distinct neighborhoods: a tight cluster of space-program entities at the high end, and a pair of Apple-focused tech publications that appear with no obvious thematic connection to Mars exploration.
International Space Station leads at 0.80, followed closely by NASA Astronauts at 0.80 and Curiosity Rover at 0.78. SpaceX (0.77) and Scott Kelly (0.76) extend the cluster, with Buzz Aldrin (0.76) and ISS Research (0.75) rounding out the space-adjacent group. By subcategory, this first peak is a mix of Research Organizations, Government entities, and Professionals — all orbiting the same institutional space-program world.
Then the data shifts. Macworld (0.73) and MacRumors.com (0.73) — both Websites covering Apple products — appear as the eighth and ninth neighbors, with NASA JPL (0.73) closing the top 10. The two-peak shape flag captures this precisely: the audience that follows NASA Mars also maps, at meaningful similarity, onto the readership of Apple-focused tech publications. These are not thematically related to Mars; they share an audience composition. No entertainment, retail, or general-news entities appear in the top 10, which keeps the cluster unusually focused despite the cross-kind surprise.
The overall picture is an audience defined by institutional science and space on one axis, and tech-enthusiast media consumption on the other.
