Aside from a couple particularly nasty collisions, dead satellites comprise the bulk of our planet’s space junk problem — as they die, get fried by radiation and become zombies, or are decommissioned, there’s nowhere for them to go. ViviSat aims to change that by servicing satellites where they are, pushing them into new orbits and allowing them to live longer.
