The Body in Space
Spaceflight affects bones, muscles, vision, and more. Learn about the changes humans may undergo during spaceflight, as well as the steps NASA takes to keep astronauts healthy and safe.
Research in Space
NASA seeks to understand how the human body changes while astronauts live and work on the space station. Learn how scientists work to maintain the health and well-being of crew members during and after their missions.
Research on Earth
NASA conducts Earth-bound simulations of life in space. Learn how scientists use such missions to study the way humans adapt to challenges astronauts may encounter on journeys to the Moon and Mars.
Extended Stays in Space
Frank Rubio, Mark Vande Hei, Scott Kelly, and others have spent an extended amount of time in space. Learn about the record-holders for the longest continuous spaceflights by U.S. astronauts.

Astronauts require food that is nutritious, appetizing, long-lasting, easy to make, and more. We strive to continuously improve the quality of space food and to satisfy the dietary needs of crew members on increasingly longer and more distant spaceflight missions.
Space simulations on Earth as a research tool
Take a peek into the lives of crew on a simulated mission to Mars. Confined inside NASA's Human Exploration Research Analog (HERA), these crew help researchers study how teams overcome isolation and confinement to accomplish mission-critical tasks.
