NASA researchers developed a Quiet Space Fan to reduce the noise inside crewed spacecraft, sharing the results with industry for potential use on future commercial space stations. Controlling noise inside spacecraft helps humans talk to each other, hear alarms clearer, get restful sleep, and minimizes the risk of hearing loss. It is best to control the noise at the source, and in spacecraft the noise often comes from cabin ventilation and equipment cooling fans. Since the earliest days of human spaceflight, there has been noise from the Environmental Control and Life Support System ventilation. NASA is working to design highly efficient and quiet fans by building …

NASA, ESA, R. Kirshner (Harvard-Smithsonian Center for Astrophysics and Gordon and Betty Moore Foundation), and M. Mutchler and R. Avila (STScI) This image, released on Feb. 24, 2017, shows Supernova 1987a (center) surrounded by dramatic red clouds of gas and dust within the Large Magellanic Cloud. This supernova, first discovered on Feb. 23, 1987, blazed with the power of 100 million Suns. Since that first sighting, SN 1987A has continued to fascinate astronomers with its spectacular light show. Located in the nearby Large Magellanic Cloud, it was the nearest supernova explosion observed in hundreds of years and the best opportunity yet for astronomers to study the pha…

Flight Engineer Joe Acaba holds a children’s book that he is reading from as part of the Story Time From Space program. Astronauts read aloud from a STEM-related children’s book while being videotaped and demonstrate simple science concepts and experiments aboard the International Space Station. Stories open up new worlds and spark curiosity in readers of all ages – and NASA is using the power of storytelling to encourage the Artemis Generation to explore STEM (science, technology, engineering, and mathematics). Through the below list of reading resources – books, comics, and graphic novels written and illustrated by NASA experts, and video read-alongs by astronauts – s…

Microgravity had no immediate effect on a person’s ability to perceive the height of an object, indicating that astronauts can safely perform tasks that rely on accurate and precise height judgments soon after arrival in space. We use the height and width of objects around us to complete tasks such as reaching for objects and deciding whether we can fit through an opening. VECTION, an investigation from the Canadian Space Agency, examined the effect of microgravity on an astronaut’s visual perception and how that ability may adapt during flight or upon return to Earth. Researchers conclude there is no need for countermeasures but suggest that space travelers be m…

On Oct. 18, 1989, space shuttle Atlantis took off on its fifth flight, STS-34, from NASA’s Kennedy Space Center (KSC) in Florida. Its five-person crew of Commander Donald E. Williams, Pilot Michael J. McCulley, and Mission Specialists Shannon W. Lucid, Franklin R. Chang-Díaz, and Ellen S. Baker flew a five-day mission that deployed the Galileo spacecraft, managed by NASA’s Jet Propulsion Laboratory in Southern California, to study Jupiter. The astronauts deployed Galileo and its upper stage on their first day in space, sending the spacecraft on its six-year journey to the giant outer planet.
