Russian-origin hardware jettisoned from the International Space Station exterior during a 2025 EVA, now tracking independently in low Earth orbit. Objects like DUPLEX are a recurring artifact of the ISS Russian segment — experiments are mounted externally on Zvezda, Nauka, or Poisk modules, operated for their test duration, then removed during spacewalks and released into free orbit to gradually re-enter. The ISS has spawned hundreds of such tracked objects. DUPLEX, likely named for its dual-function design, has now completed its mission. It is silently descending toward an atmospheric re-entry of its own, a very small piece of a very large space station finding its own path back to Earth.
