Scientists from the National Aeronautics and Space Administration (NASA) have begun experimenting on different ways to produce food in space.

Food is of primary importance in space missions. The vast void of space offers no conducive environment to create and cultivate food, however.

Since there is no freezing or refrigeration aboard the International Space Station, food must be pre-packaged and have a shelf life of about 15 years. Food must also be quick to prepare.

Scientists have turned to technology to not only fill in the nutrition and sustenance gap but also to concoct flavorful food that bolsters the morale of astronauts.

NASA's first option is the 3D printer. This advanced technology has made waves in the past years, showing its efficacy and flexibility in building creating anything from guns, tables, sculptures, organs, and more.

NASA has turned dehydrated ingredients into long-lasting powders that are then mixed by a 3D printer in oils and waters. The machine will then be able to cook meals for astronauts.

Partnering with Texas-based Systems and Materials Research Consultancy, NASA is already seeing results.

The has 3D printed pizza layer by layer. And the space agency claims its printed pizza is delicious.

While the 3D printing of food needs to be explored further more before being tested in space, this technology could lighten the task of feeding astronauts.

NASA scientists are also exploring another approach.

Students from the University of Colorado Bolder were challenged by NASA to address the challenge of preparing food in space The students' answer is robotic gardening.

Their project is called "Plants Anywhere: Plants Growing in Free Habitat Spaces." In this process, plants are placed into hydroponic growth chambers called SmartPots.

Computers and sensors keep track of the conditions of the plant, responding when plants need water.

These large steps for growing and preparing food in space could prove very useful in the first manned mission to Mars planned for 2030.
