50 years of space exploration

Detail of a graphical representation of 50 years of space travel.

Above is a detail of a large graphic illustrating 50 years of space exploration. If you follow the link the full image is about 3800 x 1700 pixels in size and quite detailed. The top of it has colored ribbons showing the mission (seen above) while along the bottom of it is a scale showing increasing distance from the sun.
