Sam Elphick on 10 Aug 11NASA has an excellent interactive timeline tracing the history of astronomy and space exploration from the Greek philosophers through the current day. Planet Quest is actually three timelines combined into one. The three timelines cover technology, discovery, and culture as it relates to astronomy and space exploration. Each element on the timeline is narrated. Users can select individual elements on the timeline or choose autoplay to hear the narration of each item in sequence.
