The cooperative space project Hayabasa set out to collect the very first samples from the surface of a near-earth asteroid, Itokawa. Scientists believe that the work will offer insight into the early history of our Solar System and the formation of the planets more than 4.5 billion years ago.

A European Space Agency-led team of astronomers has determined the rapid space weathering seen on asteroid surfaces is most likely caused by the solar wind. The study led by ESA scientist Pierre Vernazza reveals that solar wind ages and reddens asteroid surfaces much more quickly than previously thought -- in less than a million years.
