Evolution of space population from the earliest days in space to present
This video shows an animation of how the space population has evolved from the beginning of the space era to present. Initially, due to the sparsity of objects in space, we depict the evolution up to 2005 showing the discrete tracked objects and their count overtime. Then, beginning in 2005, we transition to a spatial density depiction, showing via a color scale how many objects occupy a given 100 by 100 by 100 kilometer voxel in space. From 2005 onward, we also show fragmentation events that have occurred over time, accompanied by a plot of how many space objects exist as a function of time.
