The Planetary Society Blog: April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science. Before I go into mission-by-mission detail, here's Olaf Frohn's marvelous map of where all of our explorers are on ....
ESA’s Automated Transfer Vehicle Johannes Kepler is more than just a cargo carrier for the International Space Station, it is also an on-orbit refueling station and orbit booster.

Although they aren’t particularly fond of the comparison, scientists from the GOCE satellite team had to admit that new data showing Earth’s gravity field – or geoid — makes our planet look like a rotating potato. After just two years in orbit, ESA’s sleek and sexy GOCE satellite (Gravity Field and Steady-State Ocean Circulation Explorer) [...]

The research project , which was recently launched , aims to improve generator efficiency by 0.5 percentage points to 99.5 percent . Large power plants would achieve significant fuel savings and thus greatly reduce their carbon dioxide emissions as a result of such an increase .

Here we use these considerations to provide a maximum estimate of wind power availability over land . We use several different methods . First , we outline the processes associated with wind power generation

This image may give you a hint as to : why It’s shaped like a cartoon dog bone It circles the Sun out past Mars , tumbling end-over-end , and its origins have always been something of a mystery . However , new observations and analysis reveal quite a bit about how this asteroid got its unusual shape . I won’t spoil it , but instead simply point you to Emily Lakdawalla’s excellent summary of Kleopatra on The Planetary Society blog . It’s a tale
