Space Probes

Processed images from the Zond 3 mission

Here are processed images from the Zond 3 mission. These are the first clear images from the Moon's far side, obtained in 1965.
The original images (and extensive information) can be found here:,

Processing consisted on removal of vertical and horizontal image stripes and noise reduction. Parts with missing data were painted with a uniform gray and the black sky background painted black.

Partial mosaics were created using some frame sequences. Spacecraft movement requires some re-projection of the images in order to create a global mosaic. This was done in the "all frames mosaic", were all returned images were used to increase area coverage and improve signal-to-noise ratio of the final image.
