2011 A good year for space

It's usually impossible to predict science headlines for the year ahead: Small labs could come out of nowhere with amazing discoveries, long-expected findings might fail to materialize, and "settled science" may be thrown into turmoil. But one field--maybe more than any other--gives us strong hints on what to expect. Thanks to heavy legislation, complicated engineering, and astronomical distances travelled, we can see into the future of space exploration with some confidence.
