&gt; The argument that people in favor of decommissioning the ISS should make is we need a bigger, better, further away one that we could use to go cheaply to the moon, asteroid belt, mars, and the Jovian and Saturnian moons.<p>That is the answer to my question. Should we sink the ship because it is old and we have no use for it or should we sink it because we need another one and can&#x27;t bear the cost of maintaining two?<p>If someone is willing to use it, then they must pay for it&#x27;s maintenance. For NASA it&#x27;s mission was accomplished, and it&#x27;s time to move on.
