Army helps to meet nutritional needs of Mars astronauts
CFD is working on a breakfast bar as a meal replacement to be used at a space station and possibly during a Mars mission. NASA developed the bar, and Natick is working on refining it.
"NASA is interested in a 10-percent weight reduction, and they achieved that through the bar, but they didn't have the capability to refine it," Froio said. "Natick is investigating two ways to reduce weight and volume. One is a conventional compression method, which uses high pressure.
"The other is a novel technology called sonic agglomeration that basically uses sonic waves to compress the bar and make the ingredients stick together. So, we are looking at those two technologies."
