NASA's DASS next-gen search and rescue system will pinpoint those in distress faster

The satellite-aided search and rescue technology pioneered by NASA is credited with saving more than 27,000 lives worldwide since its inception nearly three decades ago. Now the agency has developed new technology that will more quickly identify the locations of people in distress and reduce the risk to rescuers.  Read More

Global Positioning System (GPS) devices have permeated society to the point where millions of us rely on them daily for directions, locations and traffic avoidance (if only they could tell me where I left my car keys). GPS satellites send signals to a receiver in your handheld or car-based GPS navigator, which calculates your position on the planet based on the location of the satellites and your distance from them. The distance is determined by how long it took the signals from various satellites to reach your receiver. But have you ever thought what tells the GPS satellites where they are in the first place?  Read More

NASA's Interstallar Boundary Explorer (IBEX) has sent back data to scientists who were abl...

Move over Google Maps, NASA's Interstellar Boundary Explorer (IBEX) spacecraft has given scientists the tools to construct the first comprehensive sky map of our solar system and where it resides in the Milky Way galaxy. NASA says the new view will change the way researchers study the interaction between our galaxy and sun.  Read More

NASA has a warning for everyone planning a trip to Mars in the near future – it might be a good idea to wrap yourself in an extra layer of tinfoil when you travel According to sensors on NASA's ACE (Advanced Composition Explorer) spacecraft, galactic cosmic rays have just hit a Space Age high, reaching levels 19 percent higher than observed in the past 50 years and sparking a rethink on the radiation shielding needed for astronauts.  Read More

Pretty as a picture … this mosaic of M31 merges 330 individual images taken by the ultravi...

In a galaxy far, far away … about 2.5 million light years, in fact, lie approximately 20,000 hot, young stars and dense clusters that comprise the Andromeda Galaxy. The galaxy, known as M31 in the constellation Andromeda, was recently captured by an ultraviolet optical telescope aboard NASA’s Swift satellite, and delivers the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet.  Read More

What resemble dainty butterfly wings are actually roiling cauldrons of gas heated to more ...

New images from the rejuvenated, more powerful Hubble Space Telescope have universally delighted astronomers. Last week, observations from four of its six operating science instruments were released by NASA. They include colorful, multi-wavelength pictures of far-flung galaxies, a densely-packed star cluster, an eerie ‘pillar of creation’, and a ‘butterfly’ nebula.  Read More

After the Phoenix lander has finished scraping away at Martian soil, the MAVEN spacecraft will examine the atmosphere of the red planet. The US$485 million Mars Atmosphere and Volatile EvolutioN program is the second stage of NASA’s Mars Scout program, following the successful Phoenix mission. The MAVEN craft will study the planet’s atmospheric gases, upper atmosphere, solar wind, ionosphere, planetary corona, solar EUV and SEPS, and investigate past climate change.  Read More

April 7, 2008 Using measurements taken by the Rossi X-ray Timing Explorer satellite, NASA scientists have identified the smallest known black hole in the universe. At 3.8 times the mass of our Sun and estimated at only 15 miles in diameter, the black hole known as XTE J1650 is also close to the smallest size thought to be theoretically possible for such an object.  Read More

The Cosmic Ray Energetics And Mass (CREAM) payload is launched near NSF's McMurdo Station,...

January 7, 2007 A record three long-duration, sub-orbital flights were launched and operated in Antarctica during this current Southern-Hemisphere summer, marking a new milestone for the almost 20-years of scientific ballooning in the region. The achievement was the result of a partnership between the National Science Foundation (NSF) and the National Aeronautics and Space Administration (NASA) with NSF providing infrastructure and logistics and NASA providing the satellite communications link.  Read More
