Wait a second, it says they had to destroy mass climate orbiter because the development and underlying software used different metric system ?<p>It&#x27;s bit hard to digest. ( Although just checked wikipedia, it also says so ) How can a high performance organisation like NASA could make such a simple yet fatal mistake ?<p>Wikipedia page of Mars Climate Orbiter says that NASA was informed about this discrepancy by two people, but the &quot;concerns&quot; were dismissed.<p>What am I getting wrong here ? These are not the &quot;concerns&quot; you simply dismiss in a space mission. Could there be another story to this ?
