Ghostly ring found circling dead star

An international team of scientists has found a strange ring around a dead star by using images taken by NASA's Spitzer space telescope. This star, called SGR 1900+14, belongs to a class of objects known as magnetars. According to NASA, a magnetar is 'a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.' So far, about a dozen magnetars have been found. An amazing thing about these stellar objects is their magnetic field. One of the researchers said that 'magnetars possess magnetic fields a million billion times stronger than the magnetic field of the Earth.' But read more...

Using satellite imagery to explore ancient Mexico

An interdisciplinary team of researchers at the Rochester Institute of Technology (RIT) is using satellite imagery to peer into the ancient Mexican past. Bill Middleton, an archeologist, is teaming up with computer scientists to build the most detailed landscape map of the southern state of Oaxaca in order to learn more about the Zapotec civilization. According to Middleton, who probably spoke only about Mexico, the Zapotec people 'had the first writing system, the first state society, the first cities.' The project is funded by National Geographic and NASA which is providing three years of images taken by Earth Observing 1 and Landsat satellites. But read more...

Self-healing computers for NASA spacecraft

As you can guess, hardwired computer systems are much faster than general-purpose ones because they are designed to do a single task. But when they fail, they need to be totally reconfigured. This can be just a costly problem in a lab on Earth, but it can be vital in space. This is why a University of Arizona (UA) team is working with NASA to design self-healing computer systems for spacecraft. The UA engineers are working on hybrid hardware/software systems using Field Programmable Gate Arrays (FPGAs) to develop these reconfigurable processing systems. As said the lead researcher, 'Our objective is to go beyond predicting a fault to using a self-healing system to fix the predicted fault before it occurs.' But read more...

NASA fights wildfires from the sky

Last week, I wrote that NASA was checking coastal waters from space. It seems that NASA wants to appear as a very environmental-friendly organization. It is helping the U.S. National Oceanic and Atmospheric Administration (NOAA) with airplanes monitoring great lakes algae. It also is collaborating with the U.S. Forest Service on wildfire imaging missions. NASA is using an unmanned aircraft named 'Ikhana' -- a Native American word from the Choctaw Nation meaning intelligent, conscious or aware -- for imaging wildfires in California, Idaho, Montana and Wyoming. Images collected from the different sensors onboard are transmitted via satellite to a ground station where they are analyzed and transmitted as a Google Earth overlay to fire experts.

NASA wants to find another Earth

NASA held a press conference on April 12 to discuss its plans for using its new spacecraft, called Kepler, to search for planets that may have extraterrestrial life. CNET News.com's Zamir Haider reports.

NASA paints Google Earth with near real-time information

NASA is now providing some interesting KML files that add near real-time overlays to Google Earth.  The information they are using comes from MODIS (Moderate-resolution Imaging Spectroradiometer) -- some data from this source (updated daily) can be viewed on Google Earth by clicking here.

Will RFID tags work on Mars?

According to Computerworld, NASA will start to test this summer if RFID technology can survive in outer space. A variety of RFID tags will be on the space shuttle Endeavour in July during a trip to the International Space Station. Then they'll be installed inside containers attached to the exterior of the ISS and stay there for a year before a return to Earth for analysis. If these initial tests are successful, NASA will check at the end of 2009 if RFID tags will work on the Moon. But the real goal is to ease the daily lives of the astronauts who will travel to Mars.

Smoke detectors for space

Engineers at NASA are developing new smoke detectors for spacecrafts to prevent fires in space. As smoke particles in microgravity are bigger than on Earth, they had to modify the smoke detectors installed in your kitchen. NASA designed two space stations experiments to test these smoke detectors. But read more...

Discovery's safety checked by laser

NASA really wants to know if it will be safe for its shuttle to come back to Earth. So it will check the exterior of Discovery from the ground to improve safety when it's launched from the Kennedy Space Center in Florida. A laser system will be on board of Discovery to check in real time to see if the shuttle is damaged or not.
