Spirulina owes its significantly growing reputation as a space food to the fact that it is super nutritious and very compact. As early as the 1970s, NASA discovered that spirulina is actually a safe and practical food choice that is completely suitable for being carried into space. The composition of spirulina makes it one of the most concentrated foods available to humanity. Moreover, it increases energy, it is very nutritious, it helps to detox the body by removing toxins and it is also incredibly easy to digest. Therefore, it is an excellent choice for those who will travel in space for weeks or even months!
While it's a routine process on Earth, we need to understand how it works in space before we can exploit it. The experiment lasts one month while the amount of oxygen from the algae is measured.
The microalgae will be analyzed after the return to Earth. They will be looking at genetic information to get a clearer picture of the effects of weightlessness and radiation on the plant cell. Arthrospira is known to be highly resistant to radiation, but researchers should check how well it can withstand conditions in space.
The Artemiss project is part of the Micro-Ecological Life Support System Alternative, or Melissa, which develops regenerative life support technologies. Melissa covers many research and teaching activities, such as the AstroPlant citizen science project, which collects data on how plants grow under different degrees of light.
