2000 - Close encounter with a space rock. A half km wide object known as 2000 QW7 -- only discovered August 26, 2000, with NASA/JPL's Near Earth Asteroid Tracking system (NEAT) passed Earth at a distance 12 times greater than Earth-Moon distance. In astronomical distances, a near miss! 2000 QW7 was fast-moving and unusually bright. Bill Hollenbach captures the images on CCD

1979 -Pioneer 11 Flyby Of Saturn, closest approach 20,900 kms (13,000 miles). It took the first close-up pictures of the planet. Instruments located two previously undiscovered small moons and an additional ring, Pioneer 11 charted Saturn's magnetosphere and magnetic field and found its planet-size moon, Titan, to be too cold for life. 

1859 - Solar physicist Richard Carrington observes the first solar flare ever recorded. An intense aurora followed the next day.

It is my conclusion that human evolution and the motions of matter in space are intrinsically linked. The observation and understanding of the complexity of biological history on Earth cannot be complete without the tandem observation and understanding of a dynamic greater cosmos. - SpaceGene
