Morrow’s technology attacks one of the major drawbacks of being an astronaut: the food. As a senior scientist at Orbital Technologies, Morrow is working on better ways to grow plants in space so that one day, astronauts can trade in their processed, vacuum-packed meals for fresh greens. In 2002, a compact plant-growth system he helped develop was tested aboard the International Space Station, and other models have been taken on space shuttle flights. Larger models of such systems might not just enable longer space missions, Morrow says—they could help people grow food while living on the moon or Mars.
