Exposure to microgravity leads to profound physiological changes that challenge human health during spaceflight and have significant implications for long‐duration missions. Research has demonstrated ...

Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions ...

Simulated effects of microgravity, created by 60 days of constant bed rest, severely disrupts rhythmic gene expression in humans, according to a new study. Simulated effects of microgravity, created ...

Simulated effects of microgravity, created by 60 days of constant bed rest, severely disrupts rhythmic gene expression in humans, according to a new study from the University of Surrey. Astronauts ...

Q As a former NASA mission planner, I would signal a "no-go" for human colonization of the moon and Mars. The human body's ...

Expedition 74 crew members conduct muscle, vein, and respiratory studies aboard the International Space Station to examine microgravity’s effects on blood flow, exercise response, and cardiovascular ...

While most people assume their height remains constant, science shows that due to gravity, humans can become 1–2 centimeters shorter by the end of the day. But in space, the effect is far more ...

Human spaceflight is built on a simple paradox: the farther people travel from Earth, the more fragile their bodies and missions become. NASA has distilled that reality into five core hazards that ...

Humanity has been reaching for the stars for decades. Moon landings, Mars rovers, and long stays on the ISS. But there’s one question that seems to ha.

Dear Doctors: As a former NASA mission planner, I would signal a“ no-go” for human colonization of the moon and Mars. Dear Reader: You are referring to a column prompted by a reader's son, who became ...
