What is the news?

These days NASA is conducting a special scientific study on the International Space Station (ISS). The aim of this research is to understand how fermented food items and essential nutrients behave in space. Normal packaged food is not sufficient when in space for long periods of time. Therefore, scientists are looking at whether microorganisms can make the necessary nutrients in space, so that it can help in future lunar and Mars missions.

What is Bionutrients Project?

NASA’s Bionutrients Project focuses on producing essential nutrients in space with the help of microorganisms. The process is similar to making yogurt or kefir on Earth, where microorganisms transform the food. On the ISS, the crew allows yeast and starter cultures to grow in special packs mixed with water. Later these samples are frozen and sent to Earth, so that their effectiveness and safety can be tested.

Why is fermentation necessary in space?

The challenge is to keep food safe for long periods of time in long space missions. Currently, most of the food is freeze-dried or packaged, which lasts for a limited time. If humans are to live on Mars or the Moon for a long time, there will be a need for fresh and nutritious food. Scientists want to know how the fermentation process works in microgravity and space radiation and whether it can produce safe food.

How will we get help in future missions?

Samples of these experiments are brought to Earth by vehicles like Space-X and are tested in NASA’s lab. Scientists look at how fast the microorganisms grow and how many nutrients they make. This information will be useful in preparation for Artemis mission and Mars journey. This could help provide fresh, safe and nutritious food to future astronauts during long journeys.
