NASA Now Ready to Detect World-threatening Solar "Storm of the Century" The Earth's magentic field serves a shield against solar radiation. However in particularly intense solar storms it can be penetrated, which could destroy satellites in space and electronics on the "sunny side" of Earth at the time of the storm. (Source: NASA) The Solar Dynamics Observatory launches in Florida. (Source: NASA) The SDO will allow researchers to detect a "space Katrina" event and prepare the Earth for its impact.
46 Fabulous Photos of Endeavour’s Last Ever Spacewalk May 27th, 2011: the last spacewalk for NASA’s Endeavour astronauts. Here, a fish-eye lens attached to an electronic still camera was used to capture this image of NASA astronaut Michael Fincke (top center) during the mission’s fourth session of extravehicular activity (EVA) as construction and maintenance continued on the International Space Station.

New Diamond, the Size of a Planet, Found The new planet is more dense than anything observed before, and is made almost entirely of carbon. Because the molecules are so tightly packed together, researchers calculate that it must be crystalline in nature, making it effectively diamond. The study was led by Professor Matthew Bailes of Swinburne University of Technology in Australia and published in the journal Science.
NASA Sounds NASA's mission of discovery and exploration is being showcased in a custom-produced Internet music radio station that is crafted specifically to speak the language of tech-savvy young adults. Third Rock - America's Space Station offers listeners a New Rock/Indie/Alternative format. The station is being developed and operated at no cost to the government through a Space Act Agreement with Houston-based RFC Media. Third Rock also will help partner companies fill high-tech job openings in the engineering, science and IT fields. An 'Ion Funnel' Could Help Future Mars Missions Identify Signs of Alien Life The Mars Curiosity Rover NASA/JPL-Caltech Tapping a bit of frat-boy ingenuity, researchers at NASA’s Jet Propulsion Lab (JPL) have devised a new way for an old space exploration instrument to suck down large volumes of vaporized particles and analyze rocks for their compositions using an ion funnel, a process that could speed analysis, lighten instrument loads, and improve the odds of finding signs of life. Mass spectrometry is an old space standby--the Mars Science Laboratory, launching in November, will host spectrometry instruments as part of its science suite--used largely to identify the composition of soil and rock on the Martian surface.
NASA and DARPA Want a "100-Year Starship," As Long as They Don't Have to Build It Since its inception (okay, since the early 1960s) the United States has been the world leader in space travel and exploration, taking the lead in crafting mankind's vision and agenda for humanity's role in space. So it made sense when NASA and DARPA announced their joint "100-Year Starship" study last year to explore the possibility of a one-way manned mission to another planet. But this initiative isn't quite as exciting as it seems; sure, the United States government would like to see humans explore and settle deep space. It just wants someone else to do it.
2011 May 7 - Dawn of the Planets Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2011 May 7 New drug could cure nearly any viral infection Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago. However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers at MIT’s Lincoln Laboratory has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection. The microscope images above show that DRACO successfully treats viral infections.
NASA Snaps the First 360-degree Image of the Sun - Technology News by ExtremeTech A little more than four years ago, NASA launched a twin pair of spacecraft as part of their STEREO (Solar TErrestrial RElations Observatory) mission. The crafts traveled in opposite directions along the Earth’s orbit en route to positions on opposite sides of the sun. This past Sunday the two crafts reached their respective destinations and—for the first time—captured a 360-degree view of our local celestial heavy. The space agency is now being fed a steady stream of images of the sun from opposite sides that they are able to combine into 3D models. The STEREO probes are specifically tuned to four wavelengths of extreme ultraviolet radiation which can be used to trace key aspects of solar activity such as solar flares, tsunamis, and magnetic filaments.
Is the Universe a Holographic Reality? The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news.
NASA Engineers Propose Combining a Rail Gun and a Scramjet to Fire Spacecraft Into Orbit In April, President Obama urged NASA to come up with, among other things, a less expensive method than conventional rocketry for launching spacecraft. By September, the agency's engineers floated a plan that would save millions of dollars in propellant, improve astronaut safety, and allow for more frequent flights. All it will take is two miles of train track, an airplane that can fly at 10 times the speed of sound, and a jolt of electricity big enough to light a small town. The system calls for a two-mile- long rail gun that will launch a scramjet, which will then fly to 200,000 feet. The scramjet will then fire a payload into orbit and return to Earth.
