What do Stonehenge, Mayan pyramids, and a spacecraft a million miles away have in common? They're linked by a human need to explore and understand the Sun, moon, planets, and stars. This year's Sun-Earth Day, "Ancient Observatories: Timeless Knowledge," is aimed at students and museums and focuses on the link between ancient and modern observatories. A joint venture between NASA and the Exploratorium of San Francisco, the event traditionally occurs on or near the spring equinox; this year it falls on March 20. Resources include printed and electronic material, television programming, and a webcast.
Media are encouraged to cover activities in their communities. Background broadcast and web materials will be made available on NASA TV and NASA's web site on March 18.
