What will it take to sustain humans on Mars? The answer is self-sufficiency far away from Earth’s protective harbor.
Utah State University scientists Bruce Bugbee and Lance Seefeldt were part of the team that successfully conducted a five-year, $15 million NASA-funded multi-institution project exploring this question. NASA recognized their team’s efforts April 24, with an agency Group Achievement Award. The recognition is one of 14 NASA Honor Awards bestowed annually.
Botanist Bugbee and biochemist Seefeldt were among the principal investigators, appointed in 2017, for the Center for Utilization of Biological Engineering in Space (CUBES) Space Technology Research Institute (STRI). The center, whose partnering institutions include the University of California, Berkeley; University of Florida, Stanford University and University of California, Davis along with Utah State, is aimed at supporting biomanufacturing for deep space exploration.
CUBES is focused on cutting-edge biotechnology to optimize food and plant-made therapeutics in space, as well as to enable production of biomaterials and energy.
“It will take more than a year to get supplies from Earth to Mars, and that supply line is too slow and costly,” says Seefeldt, professor and head of USU’s Department of Chemistry and Biochemistry. “Mars explorers will have to generate their own food, pharmaceuticals and infrastructure.”
Bugbee, who has conducted space-related plant experiments over three decades, says Mars greenhouses will need to be constructed underground to withstand the planet’s harsh environment. CUBES researchers are developing ways to supply growth chambers with sunlight and nutrients.
“We’re determining the kinds of plants, including rice, lettuce, potatoes and possibly soybeans, that can be successfully grown and will provide a nutritionally sustaining diet for the Mars residents,” says Bugbee, professor in USU’s Department of Plants, Soils and Climate and director of the Crop Physiology Laboratory.

Since 1888, Utah State University established itself as a premier research institution known through the world for its intellectual and technological leadership. USU’s main campus is in Logan, plus 30 campuses throughout Utah. And as long as WiFi is available, you can be an Aggie anywhere through USU Online.
USU competes in 16 NCAA Division I sports. Our student section, the HURD, is one of the loudest and rowdiest in the nation. The diehards become True Aggies by kissing on the block “A” on Homecoming. Adrenaline junkies sled down Old Main hill between classes or rock climb outside. And everyone eats Aggie Ice Cream - even with a foot of snow on the ground.
