Unfortunately, there are between 30,000 and 100,000 untracked objects between 1 cm and 10 cm diameter (large enough to cause serious damage to spacefaring vehicles), and an unknown but enormous number of particles smaller than 1 cm (many of which could damage sensitive systems on impact). While the space environment is extremely large and the probability of an impact is still small, that probability is growing. .or some space missions active protection through shielding is already a requirement (e.g. the International Space Station). Getting this shielding to orbit is an added expense to an already low-profit-margin industry. Any weapon use in space, but particularly proliferating weapons use in space, could readily make space a no-go area of dangerous debris, in the process pre-empting commercial and civil development.
