Site of the Day for Wednesday, March 11, 2009 Exploring the Planets Today's site, from the Smithsonian's National Air and Space Museum, offers an exhibit showcasing the solar system as viewed from earth and from space. Gentle Subscribers will discover a commendable presentation, which considers the distant past to the modern day scientific understanding of what is known of the planets. "Exploring The Planets highlights the history and achievements of planetary explorations, both Earth-based and by spacecraft. ... See just how big each planet and its major satellites are relative to each other in the scale model of the Solar System. See where the planets are in relation to the Sun and to each other and learn just how big the Sun is compared to all the planets in our Solar System." - from the website Beginning with an excellent Table of Contents clearly delineating its direction, this comprehensive exhibit sheds light on how man has regarded the planets over millennia, from his first tentative steps to make sense of the heavens, to the use of increasingly sophisticated devices to explore the solar system. From the remarkable images in the gallery, to the conclusions reached in the discipline of comparative planetology, the exhibit spotlights a broad array of features. Additional sections delve into comets and asteroids, along with a look at what's new in planetary exploration.
