The Science and Technology Directorate at NASA's Marshall Space Flight Center sponsors the Science@NASA web sites. The mission of Science@NASA is to help the public understand how exciting NASA research is and to help NASA scientists fulfill their outreach responsibilities.
Going to the Moon? Don't forget your duct tape. Thirty-six years ago when Apollo 17 astronauts found themselves a quarter million miles from home with a damaged moonbuggy, a roll of "good old fashioned American gray tape" saved the day.
Unlike Earth, the firmament of the moon is directly exposed to charged particles from the sun. What happens to moondust under the onslaught of solar wind? Researchers in a NASA-supported lab are finding some surprising answers.
NASA's Lunar Reconnaissance Orbiter will play some crafty tricks to find water on the moon, such as using starlight to see into deep, dark craters and checking the temperature with a scientific device known as "Diviner."
Amateur astronomers around the world have noticed, something is happening to Saturn. The planet's rings are rapidly narrowing and, if this continues, before long they'll be just a wafer-thin line almost invisible to backyard telescopes.
The surprises continue. Scientists studying the harvest of photos from MESSENGER's Jan. 14th flyby of Mercury have found several craters with strange dark halos and one crater with a spectacularly shiny bottom.
Imagine living on a planet where Northern Lights fill the heavens at all hours of the day. Around the clock, even in broad daylight, luminous curtains shimmer and ripple across the sky. News flash: Astronomers have discovered such a planet. Its name is Earth.
NASA's Messenger spacecraft has beamed back some surprising new data from the planet Mercury. Highlights include a weird crater nicknamed "the Spider," a planetary tail of hydrogen atoms, and measurements that show giant Caloris basin is even bigger than researchers thought.
Last week's historic flyby of Mercury by NASA's MESSENGER spacecraft gathered 500 megabytes of data and more than a thousand high-resolution photos covering nearly six million square miles of previously unseen terrain.
A cutting-edge laboratory has opened in Alabama. Its mission: to combat diseases ranging from asthma to malaria to stroke using data from NASA satellites. Space scientists and public health officials are working together to train the doctors of tomorrow in this far-out approach to medicine.
