Michael Najjar: Orbital Cascade 57-46
Orbital cascade57-46 visualizes the demographics of defunct objects in orbit around the Earth from 1957 to 2046. This includes everything from spent rocket stages, and old satellites to fragments resulting from disintegration, erosion, and collisions. Currently there are about 600,000 objects larger than 1cm (0.4in) in space, orbiting Earth at a velocity of approximately 28,000 kmph (17,400 mph) and posing a severe threat to satellites, space stations and manned spaceflights. Drawn from a data archive, each spherule in the video represents a real existing object orbiting in space.
