The space station is already is showing signs of age. Russia and the U.S. launched the first pieces in late 1998, and astronauts moved in two years later. Europe and Japan added their own segments, and Canada provided robotic arms. NASA and Elon Musk’s company on Wednesday outlined the plan to burn the space station up on reentry and plunge what’s left into the ocean, ideally at the beginning of 2031 when it hits the 32-year mark. Where should the space remains be dumped ?
