Daniel has been near Mars for 25 years and instrumental in the development, construction, and now operation of the Mars Orbital Smelting Array (MOSA, specifically MOSA One). As Managing Director he has an office on the 900-meter long artificial satellite of Mars that captures the incoming ores from the asteroid belt, smelts them to their elemental metals, and fires the ingots off a rail launcher to be recovered near Earth. Daniel falls in love with Marion and they ultimately marry.
