A pair of stamps issued in 1960 to commemorate the success of Luna 3 in flying around the Moon and photographing its far side.
Left: Luna 3 photographing the far side of the Moon. The date on the stamp (7 October 1959) is the date on which the photographs were taken.
Right: An annotated map of the far side of the Moon, based on Luna 3’s pictures. Part of the nearside was included to assist orientation; this part lies to the left of the dotted line. As seen from the spacecraft the Moon was fully illuminated so little surface relief was visible, but the pictures did suffice to show that the far side was mostly highlands with relatively few dark mare areas.
