On a Friday night in March 2008, fans at a college basketball game at Atlanta’s Georgia Dome noticed the stadium’s scoreboard begin to sway.
For all the challenges posed by the microgravity conditions of space, weight is actually one of the more significant problems NASA faces in the development of the next generation of U.S. space vehicles.
Since designing the first space suits in the 1950s, NASA has been interested in developing materials to keep astronauts comfortable and cool.
The space shuttle is unique among spacecraft in that it glides back to Earth and lands like an airplane, usually touching ground near where it launched at Kennedy Space Center, but sometimes, in poor weather, gliding into the back-up landing site at Dryden Flight Research Center and then catching a ride back to the Cape on the back of a modified Boeing 747.
Astronauts, pilots, air traffic controllers, truck drivers, shift workers, and mountain climbers have something in common: All are at risk for impaired cognitive abilities due to stress or sleep deprivation.
Water, an increasingly precious commodity on Earth, has always been priceless in space; but “priceless” is a figure of speech—water in space does have a price, and it is an expensive one.
Johnson Space Center, NASA’s center for the design of systems for human space flight, began developing high-resolution visual displays in the 1990s for telepresence, which uses virtual reality technology to immerse an operator into the environment of a robot in another location.
In spring 2008, Dr. Scott Dulchavsky diagnosed high-altitude pulmonary edema in a climber over 20,000 feet up the slope of Mount Everest. Dulchavsky made the diagnosis from his office in Detroit, half a world away. The story behind this long-distance medical achievement begins with a seemingly unrelated fact: There is no X-ray machine on the International Space Station (ISS).
You may have heard the phrase "as difficult as walking and chewing gum" as a joking way of referring to something that is not difficult at all. Just walking, however, is not all that simple—physiologically speaking.
The absence of gravity beyond the Earth’s atmosphere is actually an illusion; at the ISS’s orbital altitude of approximately 250 miles above the surface, the planet’s gravitational pull is only 12-percent weaker than on the ground.
Beginning in 1968, NASA began researching garments to help astronauts stay cool. The Agency designed the Apollo space suits to use battery-powered pumps to circulate cool water through channels in the inner layers of the garments.
