Mercury - Mariner 10

Jumbled terrain antipodal to the Caloris Basin, Mercury

Mariner 10 image of the jumbled, chaotic terrain antipodal to the Caloris Basin on Mercury. This region is on the exact opposite side of the planet from the major impact which formed the Caloris Basin. It is believed the seismic waves generated by the impact were focussed to this point as they travelled through the planet, and that this is responsible for the chaotic appearance of this region. The large, flat-floored crater on the left is about 35 km in diameter, and north is up. (Mariner 10, Atlas of Mercury, Fig. 11-20)
