ISS Science for Everyone

Science Objectives for Everyone The BASE-A investigation will study the effect of microgravity on bacteria and how bacteria adapts to the microgravity environment on ISS. The data provided by this investigation will give scientists valuable insight into how basic organisms adapt to new environments. This information could prove valuable when planning future long duration expeditions to the Moon and Mars.

    Experiment Description

    Research Overview

    • The BASE-A investigation will provide confirmation and analysis of previous observations on short duration mission in microgravity.

    • The BASE-A investigation will allow the comparison of response of multiple bacteria under similar culturing conditions in space.

    In the BASE-A (Bacterial Adaptation to Space Environments-A) experiment, the science team will study how bacteria cope and adapt to the different space flight environmental parameters (e.g. weightlessness, cosmic radiation, space electromagnetism, space vibrations). Based on these results, scientists will try to assess how such adaptations might influence their potential to contaminate and biodeteriorate the space habitat, their potential to endanger crew health, or their function in waste recycling or food production systems. In the BASE project, scientists will also study the physiology, gene expression, gene rearrangement and gene transfer of cultures of several model bacteria grown under microgravity and other space flight conditions.
