Answer »Answer: (c)
The Soviet space probe Luna 3 of 1959 (of the E3 series) was the third space probe to be sent to the neighbourhood of the Moon, and this mission was an early feat in the spaceborne exploration of outer space.
Though it returned rather poor pictures by later standards, the historic, never-before-seen views of the far side of the Moon caused excitement and interest when they were published around the world, and a tentative Atlas of the Far Side of the Moon was created after image processing improved the pictures.
These views showed mountainous terrain, very different from the near side, and only two dark, low-lying regions which were named Mare Moscoviense (Sea of Moscow) and Mare Desiderii (Sea of Desire). Mare Desiderii was later found to be composed of a smaller mare, Mare Ingenii (Sea of Ingenuity), and several other dark craters.
