Recent studies have found that astronauts can lose up to 9% of their hip bone density after just six months in space, mirroring the accelerated aging process predicted for life on the red planet. This provides a glimpse into what does Mars do to your body, where lower gravity and higher radiation will dramatically affect human health over time.

Since the 1960s, space agencies have been exploring the use of microalgae to sustain human life beyond Earth, with the Soviet Union testing *Chlorella* in early spaceflights. But which algae is eaten by astronauts, and why are these microscopic organisms so critical for long-duration missions? Primarily, two species stand out for their nutritional and life-sustaining properties: Spirulina and Chlorella.

Currently, Earth is the only planet known to harbor life, with over 5,500 exoplanets discovered so far, none of which perfectly match our terrestrial requirements. This makes the question 'Can humans live on other plants?' a matter of extreme scientific and technological complexity, moving it from the realm of pure science fiction toward long-term strategic planning for humanity.
