2010 - Hubble Telescope team releases new pictures of Pluto and surprises everyone with changes of the planet's surface.

2004 - Rover Opportunity finds sphericals in Martian Soil.

1999 - NASA's Mars  Global Surveyor spacecraft successfully completed the aerobraking phase of the mission.... "During the aerobraking technique, the spacecraft uses frictional drag as it skims through Mars' thin upper atmosphere to alter the shape of its orbit around the planet.  First tested in the final days of the Magellan mission to Venus in 1994,the technique is an innovative way of changing the spacecraft's orbit while carrying less onboard fuel." (see here for press release)

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
