Abstract
The main features of the space weathering of asteroids, in particular those pertaining to the S–complex, have been analyzed and understood. However, several relevant problems remain open. In particular there are contrasting evidences for a fast reddening (timescale of the order of 106yr) and for a much slower process, by, at least, two orders of magnitude. After reviewing the status of the art and the various suggested solutions, the paper focuses on the possible de–weathering effects due to collisions: a problem which will deserve a quantitative analysis in the next future.
