Deep Space Diet: Handling Hunger on Mars

A team of researchers from the University of Hawaii at Mānoa
and Cornell University are testing new forms of food and food preparation
strategies for deep-space travel.

The university investigators have picked six volunteers to
make up the crew of a simulated Mars mission.

The mission is dubbed HI-SEAS. That stands for Hawaii Space
Exploration Analog and Simulation. It is part of a study for NASA to determine
the best way to keep astronauts well nourished during multiple-year missions to
Mars or the moon.

Along with two days of cooking lessons at Cornell’s test
kitchens, the volunteers have taken part in team-building exercises, sensory
testing and academic preparation – all in preparation for a trip in early 2013
to live in isolation for four months on a barren lava field in Hawaii.

Once they head to Hawaii, the team of volunteers will be
required to live and work like astronauts, including suiting up in space gear
whenever they venture out of a specially built simulated Martian base.

Menu fatigue

According to Cornell’s Jean Hunter, associate professor of
biological and environmental engineering, one of the biggest food challenges
astronauts face is labeled “menu fatigue”. That is, over time, they not only tire
of eating foods they normally enjoy, but also tend to eat less.

Reducing food intake can put individuals at risk for
nutritional deficiency, loss of bone and muscle mass and reduced physical

The HI-SEAS mission will test whether crew nutrition, food
intake and food satisfaction can be improved if crews cook for themselves and
will assess the additional resource cost of a crew-cooked food system.
