Experimental, Archived (permission renewal required to continue data sharing)
Data provided by Space-Track. Basic orbital mechanics courtesy of AMSAT-UK (note: original math links no longer active). Math converted into something usable in Flash with much help from various math experts. Special thanks to Sandy 3D team for making a pixel class for showing 3D positions.
Simple questions, "How many satellites are orbiting Earth?" and, "How far up are they?" sparked a fun adventure and a major interest boost in space activities.
Near-live simulation showcasing where 11,000+ unclassified pieces of stuff (satellites, space junk) are located around Earth.
