May 26, 2008 NASA has announced the successful touchdown of the Phoenix spacecraft on arctic plains in the north of the Red Planet. The completion of the 10 month journey was confirmed with the detection of a radio signal from Phoenix (a signal which takes more than 15 minutes to reach Earth) indicating that it had reached the Martian surface. The spacecraft reached speeds of approximately 12,000 mph before entering the top of the planet's atmosphere and beginning its decent towards a soft touchdown on its three-legs made possible by parachute deployment and finally, the use of controlled thrusters. Launched on August 4, 2007, Phoenix is the sixth lander to touch down on Mars with only five of the 11 previous international attempts having succeeded including the first successful landing of the Viking program in 1976.

Electric solar sail moves closer to reality

April 16, 2008 It's a striking image made popular in sci-fi classics like the recent Star Wars films - a spacecraft hurtles through the galaxy propelled by gigantic reflective sails that use of solar radiation in place of on-board fuel . Space organizations around the world including NASA are pursuing this technology, but a rapidly evolving project from the Finnish Meteorological Institute has taken a radically different approach by using long metallic tethers and a solar-powered electron gun to create an "electric sail" that looks very different from the depictions of pressure sails with which we have become familiar.

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.

February 20, 2008 A new report has outlined the possibility of US support for the planned UK-led MoonLITE mission, a project that aims to use a solar-powered spacecraft to fire four suitcase-sized “penetrators” at the surface of the moon at speeds of 300m/s. The penetrators would be deployed to the far side of the Moon, and one of the poles, where they would sink to depths of up to two metres beneath the moon’s surface, and analyse “Moonquakes”, study heat flows, and determine the chemical and physical structure of the Moon’s interior.

New research sheds light on Solar Wind

December 11, 2007 New images and data from the Hinode space mission have provided a better understanding of the sun’s magnetic field and the origin of solar winds that blast through the solar system. Eruptions of magnetic energy from solar winds threaten satellites, telecommunications and electric power grids on Earth and a better understanding of the solar winds, which are propelled from the sun at speeds of almost one million miles per hour, could aid in the early prediction of damaging radiation waves before they reach satellites.

Blended-Wing Boeing completes first test flight

Boeing's Blended-Wing Body (BWB) X-48B prototype completed its first test flight last week...

July 30, 2007 The traditional airplane shape is well tried and tested, but manufacturers like Boeing are moving beyond the "tube with wings and a tail" design in the push to improve fuel economy and the environmental impact for the next generation of jets. Inspired by "flying wing" designs from earlier decades like 1988's B-2 Stealth bomber, the company has been collaborating with NASA to test the viability of a Blended Wing Body (BWB) aircraft, using a flat, wide body that tapers out to thin wing-tips and aims to strike an effective middle ground between the tube and flying wing designs. A BWB design allows the entire body of the plane to generate lift and reduces drag in comparison to a tube-shaped fuselage - both of which are key factors in reducing fuel usage. The BWB design also provides a much greater cargo and passenger capacity - making it particularly attractive to the military. After months of development, ground testing and wind-tunnel testing, Boeing flew its first BWB prototype last week with the 8.5 per cent scale, 500-pound X-48B aircraft reaching 7500 feet before a successful landing under remote control.

December 21, 2006 NASA's twin Solar Terrestrial Relations Observatories (with appropriate acronym of STEREO) sent back their first images of the sun this week and with them a view into the sun's mounting activity. STEREO utilizes two nearly identical spacecraft on different trajectories to study the most energetic events on the surface and in the lower atmosphere of the Sun, and their travel through interplanetary space. Data from the spacecraft will allow scientists to construct the first ever three-dimensional views of the Sun, providing a new perspective on Coronal Mass Ejections (CMEs). CMEs are violent explosions on the surface of the Sun that can propel up to 10 billion tons of the Sun's atmosphere, at a million miles an hour, out through the corona and into space. Read More

NASA unveils plan to return humans to the moon

December 6, 2006 NASA on Monday unveiled the initial elements of the Global Exploration Strategy and a proposed U.S. lunar architecture, two critical tools for achieving the nation's vision of returning humans to the moon. The Global Exploration Strategy focuses on two overarching issues: Why we are returning to the moon and what we plan to do when we get there. The strategy includes a comprehensive set of the reasons for embarking upon human and robotic exploration of the moon. NASA's proposed lunar architecture focuses on a third issue: How humans might accomplish the mission of exploring the moon. Read More

NASA data shows rapid and dramatic changes in Arctic Sea ice

NASA data shows rapid and dramatic changes in Arctic Sea ice

September 18, 2006 If there’s any good news from the NASA release earlier this week detailing the rapid and dramatic melting of the artic icecap, it’s well disguised – perhaps that the property you bought with ocean views might soon become beachfront is all we can think of to reflect the upside. Okay, that’s a bit of an exaggeration, but the news is very concerning nonetheless. Data from NASA's QuikScat satellite shows that Arctic perennial sea ice, which normally survives the summer melt season and remains year-round, shrunk abruptly by 14 percent between 2004 and 2005. According to researchers, the loss of perennial ice in the East Arctic Ocean neared 50 percent during that time as some of the ice moved from the East Arctic to the West. The overall decrease in winter Arctic perennial sea ice totals 280,000 square miles - an area the size of Texas. "Recent changes in Arctic sea ice are rapid and dramatic," said Son Nghiem of NASA's Jet Propulsion Laboratory. "If the seasonal ice in the East Arctic Ocean were to be removed by summer melt, a vast ice-free area would open up. Such an ice-free area would have profound impacts on the environment, as well as on marine transportation and commerce." Read More

NASA's Cassini discovers potential liquid water on Enceladus

NASA's Cassini discovers potential liquid water on Enceladus

March 11, 2006 NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus. The rare occurrence of liquid water so near the surface raises many new questions about the mysterious moon. "We realize that this is a radical conclusion -- that we may have evidence for liquid water within a body so small and so cold," said Dr. Carolyn Porco, Cassini imaging team leader at Space Science Institute, Boulder, Colo. "However, if we are right, we have significantly broadened the diversity of solar system environments where we might possibly have conditions suitable for living organisms." High-resolution Cassini images show icy jets and towering plumes ejecting large quantities of particles at high speed. Scientists examined several models to explain the process. They ruled out the idea that the particles are produced by or blown off the moon's surface by vapor created when warm water ice converts to a gas. Instead, scientists have found evidence for a much more exciting possibility -- the jets might be erupting from near-surface pockets of liquid water above 0 degrees Celsius (32 degrees Fahrenheit), like cold versions of the Old Faithful geyser in Yellowstone.

March 26, 2005 A flight research project that put a 21st century twist on a century-old technology -- a high-tech derivative of the Wright brothers' wing-warping method of controlling an aircraft's turning ability -- can be summed up in two words: "It works!" That was the conclusion of project manager Larry Myers as flight tests in the Active Aeroelastic Wing (AAW) project at NASA's Dryden Flight Research Center at Edwards Air Force Base, Calif., neared their end.
