The recipe for a successful trip to Mars? Spam, Nutella and a sprinkling of couscous
A team of ‘gastronauts’ have spent the past four months living in a small dome on a barren Hawaii lava field, trying to find out what foods astronauts might eat on a mission to Mars. They emerged yesterday with their recipes and without the space suits they were required to wear each time they ventured onto the northern slope of Mauna Loa - an active volcano that last erupted in 1984.
The group of six had been working as part of a $1 million Nasa HI-SEAS (Hawaii Space Exploration Analog and Simulation) project on an isolated slope of a Hawaiian volcano. The aim of the project, funded by NASA’s Human Research Program, the University of Hawaii and Cornell University, was to learn about living and cooking for long-duration space missions.
In between other research projects, the team cooked up meals that were divided between freeze-dried food and meals they were able to cook themselves from the food available at the time. Team commander Angelo Vermeulen said the problem with ingredients that are not perishable is they're usually highly processed and lack fibre. He added that he was impressed with how freeze dried products taste very similar to fresh produce. But what is also important for future space missions is comfort food, he said. A favourite among the crew was nutella, the chocolate-hazelnut spread.
According to Nasa, longer space exploration in the future, namely missions to Mars in the 2030s, present the new challenge of providing food systems to support years-long journeys.
On a mission to Mars, astronauts may be able to grow their own food as well as bring along raw ingredients that they can make into tofu, bread, pasta, and flour.
However, there are several challenges to feeding a hungry crew in space. The food needs a five-year shelf life and enough variety to stay interesting.
The team has collaborated with Jean Hunter, associate professor of biological and environmental engineering, to research why astronauts lose their sense of taste in space. In low gravity more body fluids shift to the head, affecting the sense of smell, so they will also measure how fluid build-up in the head affects their sense of smell and how long that effect lasts.
Results for the latest HI-SEAS project will take several months to process all the data gathered. Findings will be presented at the International Astronautical Congress later this year in Beijing.
