This resource is aimed at professionals and informed users with a strong interest in astronomy and astronautics, and the second can be enjoyed by kids of all ages. While the content in some of the multiple categories in SpaceRef's Space Directory is currently a little thin, the site is clearly designed from the ground-up to host a wide array of space resources. In addition to the directory, the site also features breaking news, analysis, full-text briefs from NASA and the European Space Agency (ESA), a calendar of events and launches, and special sections on current missions.
