In 1999 a $125 million dollar probe headed for Mars was lost due to calculation error. The Jet propulsion laboratory used the metric system for its portion of the project while Lockheed Martin Astronautics used the English system. People were not amused.
Imagine you are working at the Jet Propulsion Laboratory and you receive instructions to accelerate a space craft to one thousand miles per hour. However, the system only accepts commands in kilometers per hour. In a two paragraphs or less communication to Houston, clarify and confirm the instructions. Be sure to include your concern as well as provide the conversion. Time is essential so you may only use two paragraphs (ten sentences).
