The physiological, emotional and psychological stress associated with spaceflight can result in decreased immunity that reactivates the virus that causes shingles, a disease punctuated by painful skin lesions. NASA has developed a technology that can detect immune changes early enough to begin treatment before painful lesions appear in astronauts and … Continue reading
Each spring as Earth passes through the debris trail from Halley’s Comet (1P/Halley), the cosmic bits burn up in our atmosphere and result in the annual Eta Aquarid meteor shower. This year the peak will occur on the night of May 5 and into the morning of May 6, with … Continue reading
Last month, when the sun unleashed the most intense radiation storm since 2003, peppering satellites with charged particles and igniting strong auroras around both poles, a group of high school students in Bishop, Calif., knew just what to do. They launched a rubber chicken. The students inflated a helium balloon … Continue reading
The words “hazard field” certainly never were associated with the Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida. To the contrary, the goal was to keep the runway area free of any hazards that might endanger the shuttle and crew during landing. But that is about to change … Continue reading
Why does NASA sometimes schedule a rocket launch for the middle of the night, or aim for a liftoff time when weather is notoriously unlikely to cooperate? The simplicity of the question belies the complexity of the answer. The best time to start a mission is based on a blend … Continue reading
A set of recent papers, many of which draw on data from NASA’s Cassini spacecraft, reveal new details in the emerging picture of how Saturn’s moon Titan shifts with the seasons and even throughout the day. The papers, published in the journal Planetary and Space Science in a special issue … Continue reading
A ground-penetrating radar instrument that NASA helped develop for the European Space Agency’s Mars Express orbiter has completed a five-month campaign of observing subsurface layering in the north polar ice cap of Mars. The campaign is a highlight of the orbiter’s extended mission. The Mars Advanced Radar for Subsurface and … Continue reading
NASA’s Cassini spacecraft successfully completed its closest-ever pass over Saturn’s moon Dione on Monday, Dec. 12, slaloming its way through the Saturn system on its way to tomorrow’s close flyby of Titan. Cassini is expected to glide about 2,200 miles (3,600 kilometers) over the Titan surface on Dec. 13. In … Continue reading
NASA transferred title and ownership of space shuttle Enterprise to the Intrepid Sea, Air & Space Museum during a ceremony on Sunday, Dec. 11, at the museum in New York City. The transfer is the first step toward Intrepid receiving Enterprise in the spring of 2012. “NASA is proud to … Continue reading
In 16 years of data observations, the Solar Heliophysics Observatory (SOHO) — a joint European Space Agency and NASA mission –- made an unexpected claim for fame: the sighting of new comets at an alarming rate. SOHO has spotted over 2100 comets, most of which are from what’s known as … Continue reading
