Building an Astronaut's Diet

摘要

Food is key to our daily functions, fueling our activity and fortifying our bodies and minds. But most of us with access to various food sources don't need to worry about meal prepping quite as much as NASA. In space, where astronauts confront drastic environmental and physical changes, the need for safe, nutritious and energy-laden food is particularly vital to overall health. But for those traveling far from Earth's food supply, it's particularly challenging to produce, transport and prepare healthy food. Beyond providing energy and nourishment, space meals must be palatable and stay safe for consumption for months - or even years.
