A landmark study published in Science Advances found that 0.67g is the minimum gravity threshold needed to preserve muscle function—and Mars's 0.38g falls well below it. The finding, based on mice exposed to varying gravity levels aboard the ISS using JAXA's MARS centrifuge, raises fundamental questions about whether long-duration human habitation on Mars is biologically viable without radical new countermeasures like artificial gravity, pharmaceutical interventions, or advanced bioengineering.
