The MESSENGER robotic explorer has completed its first fly-by of Mercury, and is now returning the data it gathered. At right is one of the first images it sent back, including about half the surface of the planet that has never had high-resolution images made of it before. The many instruments on MESSENGER collected a lot of data on this brief fly-by, and it will take some days before it all gets back to Earth and “digested”. Scientists will be studying it for years to come...More of these, please, NASA – and less of the incredibly expensive and not-very-productive manned missions. Please.
