From Psychology to Space: Alexandra Whitmire’s Journey and Impact in NASA’s Human Research Program

NeRD

From navigating the depths of the human mind to exploring the vastness of space, Dr. Alexandra (Sandra) Whitmire helps lead research on the effects of prolonged isolation and confinement as NASA prepares to voyage to the Moon and eventually Mars.  Whitmire is the lead scientist for the Human Factors and Behavioral Performance element (HFBP) within NASA’s Human Research Program, or HRP. HFBP selects, supports, and helps design studies for Johnson Space Center’s HERA (Human Exploration Research Analog), which conducts missions simulating isolation and confinement to further understand psychological effects on…

4 Min Read Space Station Research Advances NASA’s Plans to Explore the Moon, Mars The full moon is pictured as the International Space Station orbited 254 miles above the Pacific Ocean northeast of Guam. Credits: NASA Space, the saying goes, is hard. And the farther humans go, the harder it can get. Some of the challenges on missions to explore the Moon and Mars include preventing microbial contamination of these destinations, navigating there safely, protecting crew members and hardware from radiation, and maintaining and repairing equipment. Research on the International…

Counteracting Bone and Muscle Loss in Microgravity

NeRD

In microgravity, without the continuous load of Earth’s gravity, the tissues that make up bones reshape themselves. Bone cells readjust their behaviors—the cells that build new bone slow down, while the cells that break down old or damaged bone tissue keep operating at their normal pace so that breakdown outpaces growth, producing weaker and more brittle bones. For every month in space, astronauts’ weight-bearing bones become roughly 1% less dense if they don’t take precautions to counter this loss.  Muscles, usually activated by simply moving around on Earth, also weaken…
