As humanity embarks on interplanetary exploration and envisions future colonies beyond Earth, understanding the impact of extreme environments on life becomes paramount. Among these factors, the hypomagnetic field (HMF)-a condition where the protective geomagnetic field is absent-remains poorly understood, especially regarding its effects on (micro)organisms. To our knowledge, this is the first study to examine how short-term exposure to an HMF (24 h to 7 days) affects the growth of three different microorganisms, , , and , using a specialized hypomagnetic chamber and advanced spectrophotometric analysis. We demonstrate significant growth inhibition in (23%) and (68%), with remaining unaffected. This inhibitory effect appears reversible, diminishing as organisms return to normal geomagnetic conditions. These findings reveal that the HMF acts as a temporary environmental stressor, underscoring the need for deeper exploration of its biological effects. Our work sets the stage for further research into how the space environment may shape microbial ecosystems critical to future human endeavors in space.
随着人类开始进行星际探索并设想在地球之外建立未来殖民地，了解极端环境对生命的影响变得至关重要。在这些因素中，低磁场（HMF）——一种缺乏保护性地磁场的状况——仍然知之甚少，尤其是关于其对（微）生物的影响。据我们所知，这是第一项使用专门的低磁场室和先进的分光光度分析来研究短期暴露于低磁场（24小时至7天）如何影响三种不同微生物、和生长的研究。我们证明在（23%）和（68%）中出现了显著的生长抑制，而不受影响。这种抑制作用似乎是可逆的，随着生物体回到正常地磁场条件下而减弱。这些发现表明，低磁场充当了一个临时的环境压力源，强调了对其生物学效应进行更深入探索的必要性。我们的工作为进一步研究空间环境如何塑造对未来人类太空活动至关重要的微生物生态系统奠定了基础。
