Magnetic anomaly data are calculated with the lunar magnetic field model of ref. 25. A spherical surface of 1,737 km from the centre of the Moon was used as the lunar surface. The Winkel Tripel projection, centred on the lunar nearside–farside boundary at 90 °W, was used for the map. The landing sites of the lunar missions are indicated. The South Pole–Aitken basin and Apollo crater are shown as dashed white and yellow lines, respectively. Different symbols represent various lunar exploration missions.
