The proposals are designed to support NASA's deep space missions, such as that which Orion...

NASA is preparing to launch its Orion spacecraft in December and its Space Launch System (SLS) is scheduled to fly by 2018. However, impressive as this is, more is needed if buyer's regret isn't to set in. To avoid this, the space agency is asking for proposals to develop new technologies to send astronauts to the asteroids and Mars using "sustainable, evolvable, multi-use space capabilities."  Read More

The spacecraft’s components have all been assembled, including the launch abort escape tow...

NASA and Lockheed Martin announced on Thursday that they have completed final assembly and testing of the Orion spacecraft, which is designed to carry NASA astronauts on deep space missions. This clears the way for the first test flight in December as NASA prepares to re-enter the manned spaceflight business.  Read More

The W88 ALT 370 warhead was dropped from a crane to simulate a loading accident

Dropping a nuclear warhead may not seem like a particularly bright idea, but earlier this year Sandia National Laboratories did just that. As part of the US government’s Life Extension Program (LEP) for its nuclear arsenal, the inert W88 ALT 370 warhead was dropped from a crane in New Mexico onto a slab of concrete to test the updated design’s safety.  Read More

Electron microscope scan of a THz circuit detailing its high-electron-mobility transistors

Getting into the Guinness Book of World Records isn't just about who can eat the most hotdogs or fly a paper airplane the highest. Sometimes it involves technological breakthroughs with huge potential. Guinness has handed DARPA’s Terahertz Electronics program the award for the fastest solid-state amplifier integrated circuit. Developed by Northrop Grumman, the Terahertz Monolithic Integrated Circuit (TMIC) is a ten-stage common-source amplifier that cranks speeds of one terahertz (1012 Hz), or one trillion cycles per second.  Read More

The accident occurred less than 20 seconds after lift off of the Antares rocket (Image: NA...

At a press conference arranged only a few hours after the event, NASA released details of the explosion of the Antares rocket carrying the unmanned Cygnus supply ship to the International Space Station (ISS). The space agency said that the launch pad at Wallops Island, Virginia, where the 240,000-kg (530,000-lb) rocket went up in flames seconds after lift off has been cordoned off by firefighters until daylight because of the on-going hazards from fires, and scattered solid and hypergolic fuel from the Antares.  Read More

The chemical computer works by differences in surface tension

If you’re going out for pizza in Budapest, which would you choose to get you there; a smartphone with GPS or a drop of gel on a little maze? A team of scientists from Switzerland, Hungary, Japan and Scotland under the leadership of Empa, the Swiss Federal Laboratories for Materials Science and Technology, thinks that the gel might be your better bet because that little bit of plastic and goo is a chemical computer capable of navigating a maze faster than a satnav.  Read More

The microwalkers consist of a pair of particles, one of which has magnetic properties and ...

Ever wonder how a germ knows where to attack the body or how a white blood cell knows where to counter attack? How bacteria find food? Or how cells organize themselves to close a wound? How can something so simple do things so complex? A team of MIT researchers is seeking the answers as they develop "microwalkers" – microscopic machines that can move unguided across the surface of a cell as they seek out particular areas.  Read More

Waste water from fracking is over five times saltier than seawater (Photo: Christopher Hal...

Fracking is a highly controversial and divisive issue. Proponents argue that it could be the biggest energy boom since the Arabian oil fields were opened almost 80 years ago, but this comes at a serious cost to the environment. Among the detrimental effects of the process is that the waste water it produces is over five times saltier than seawater, which is, to put it mildly, not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well.  Read More

The Yardarm Sensor fits into the grip of a firearm to monitor use in real time

Anytime a police officer draws their weapon, it's likely to be a tense, confusing situation where split second decisions can be the difference between life and death. In an attempt to reduce some of the confusion, Yardarm has developed a wireless sensor that allows firearms to be tracked and monitored in real time thanks to a small electronics package that fits into the weapon's grip.  Read More

The odor is based on chemicals outgassing from comet 67P/Churyumov–Gerasimenko (Image: ESA...

Comets may be deep-frozen fossils that could provide clues as to the earliest days of the Solar System, but what does one smell like? Not very nice, says ESA, whose Rosetta space probe has discovered that comet 67P/Churyumov–Gerasimenko (67P/C-G) has the aroma of rotten eggs and horse dung.  Read More
