Living in space is an incredible adventure, but it presents unique challenges for the human body.
On Earth, gravity acts as a constant stressor that keeps our bones strong.
In space, without this weight, our skeletal system begins to weaken.
Astronauts can lose bone density at a rate of 1% to 2% per month, which is much faster than typical aging on Earth.
To counter these effects, astronauts perform two hours of daily exercise using specialized machines like the Advanced Resistive Exercise Device (ARED).
By observing how bones degrade in space, scientists are gaining vital insights that could lead to new treatments for millions of people on Earth suffering from osteoporosis.
