SpaceDev Dream Chaser Human Space Transport System Designed  - BBC  SpaceDev has nearly completed a small, NASA funded preliminary study that defines a safe, affordable launch system for transportation of six passengers between Earth and low earth orbits. The launch system propulsion modules would be scaled-up versions of SpaceDev's non-explosive hybrid rocket motors. SpaceDev's proprietary hybrid rocket motor technology successfully powered SpaceShipOne on its history making flights to space. The SpaceDev Dream Chaser space transportation system would be based on a combination of existing and proven technologies and designs. "By combining existing technologies and designs in a unique and innovative manner, we believe we can reduce cost, risk and time to market for commercially viable human space transport."  
After Decades Of Global Dimming, Sunlight On Earth's Surface Increases  - BBC  ETH scientists show that sunlight at the earth surface - after decades of decrease ("global dimming") - has recovered since the mid 1990s. This significantly affects Earth's climate. This trend reversal is reconcilable with changes in cloudiness and air pollution. Whereas the solar dimming could have partially counterbalanced the increasing greenhouse effect prior to the 1980s, this masking of the greenhouse effect and related impacts may have no longer been effective thereafter, enabling the greenhouse signals to become more evident during the 1990s.     

The New Colonial Space Movement  - BBC  India - possibly the most underrated spacefaring nation of all - best epitomizes this new international space race. Most of the recent publicity about India's space effort has centered on its plan to launch an unmanned probe to the moon by 2007. If successful, Chandrayan-1 would make India a member of a very select club - which includes the United States, Russia, and Japan - as the only nations able to send a spacecraft to another planet. The European Space Agency also has flown planetary missions, but only as a consortium of 16 nations. What hasn't been noted much is the long-term stability and steady growth of India's program.
