    Area of Science:

    • Space Biology
    • Gravitational Biology

    Background:

    • Gravity is a fundamental force shaping life on Earth.
    • Understanding gravity's role is crucial for space exploration and astrobiology.

    Purpose of the Study:

    • To comprehensively review the role of gravity in biological processes.
    • To assess the impact of microgravity on various life forms.

    Main Methods:

    • Review of experiments on diverse organisms (unicellular, plants, animals, fungi) in space flights.
    • Analysis of studies involving microgravity, ionizing radiation, clinostats, and centrifuges.

    Main Results:

    • Unicellular organisms showed no gravity-dependent processes in orbit.
    • Higher plants and fungi adapted, with altered movements but maintained basic structure and genetic stability.
    • Spontaneous and radiation-induced mutation rates remained largely unchanged.

    Conclusions:

    • Basic biological processes proceed uneventfully in microgravity.
    • Gravity's roles as an environmental creator, selective factor, and physiological stressor are significant on Earth.
    • Biological systems demonstrate adaptability, supporting the feasibility of long-term human space missions.
