“The purpose of NASA’s Earth Observatory is to provide a freely-accessible publication on the Internet where the public can obtain new satellite imagery and scientific information about our home planet. The focus is on Earth’s climate and environmental change.” That’s s brief description of the web site which if found on the site itself I don’t think I need to say anything else after all that’s NASA.
