COLOURFUL  MOON

OBJECT

The Moon Surface color has leaded to lots of discussion and controversy. Anyone observing the Moon naked eye or analyzing any of the images taken on the Moon during the Apollo mission would affirm that the Moon surface is grayish, monotone and lack of saturation.

However, if we take an image of the Moon and use colour enhancing techniques, then we will realize that our satellite has rich colour areas.

 

One of the best areas to appreciate the different colour on the Moon surface is the limit between Mare Tranquilitatis and Mare Serenatis. The first ‘Mare’ is dark and bluish while the second has a soft reddist brown. We have good samples of the Mare Tranquilitatis material because a lot of rocks were retrieved there and returned them to Earth during the Apollo missions.

The analysis of those Tranquilitatis soil samples found a relevant portion of titanium (TiO2) which is the cause of the blue tone.

On the other hand, Mare Serenitatis is a good example of iron-rich basalts what cause the reddish tone.
