Query: Exploring a planet, revisited   How should we place $n$ great circles on a sphere to minimize the furthest
distance between a point on the sphere and its nearest great circle? Fejes
T\'oth conjectured that the optimum is attained by placing $n$ circles evenly
spaced all passing through the north and south poles. This conjecture was
recently proved by Jiang and Polyanskii. We present a short simplification of
Ortega-Moreno's alternate proof of this conjecture.
