Zond 3 Mission to Earth's Moon

Goals: This Zond spacecraft was originally slated for a trip to Mars, but when it couldn't be prepared in time Soviet scientists instead made it a lunar mission to test basic systems and send back more photographs of the far side of the Moon.

Accomplishments: Zond 3 photographed the unseen 30 percent of the far side of the Moon. It also demonstrated successful course correction using both solar and stellar orientation, a first for a Soviet spacecraft.

Fast Facts
Zond 03 Facts It is believed this mission was supposed to be a companion to Zond 2 Mars mission, but its destination was changed when it couldn't be ready for the Mars launch window.

The spacecraft's pre-digital era camera system used onboard exposure, development, fixing, and drying prior to scanning for transmission to Earth.

The spacecraft took twenty-five visual and three ultraviolet images during its flyby.
