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

With a camera built into its front, Parrot's Jumping Sumo minidrone can quite a useful too...

With all the interest surrounding aerial drones of late, it might seem like a step backwards for Parrot to come out with a quirky two-wheeled vehicle that rolls around on the floor. But after spending some time with its new, spring-loaded minidrone, we can report the Jumping Sumo is quite a fun little toy.  Read More

From tip to tail the Impala stretches 16.7 ft (5.1 m), making it as long or longer than mo...

The long-tailed classic that is Chevrolet’s Impala has gone through many iterations since it was introduced in the late 1950s – some good, some excessively bland. The redesigned 2015 Impala LTZ is in the former camp and after 10 days of driving I was pleasantly surprised at how well Chevy has executed the overall package.  Read More

Firing lasers up the backsides of rockets could accelerate them faster without requiring e...

Russian scientists have proposed a novel way to accelerate a spaceship while in flight – firing a ground-based laser up its backside. The new technique uses a plasma flow caused by laser ablation to increase the exhaust efficiency of a traditional rocket propulsion system, and could theoretically accelerate an aircraft beyond Mach 10.  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

The new X5 M and X6 M are powered by a 4.4-liter, twin-turbocharged V8 engine

Set to debut at next month's LA auto show, BMW's new X5 M and X6 M both powered by a 4.4-liter, twin-turbocharged V8 engine that produces 423 kW (575 hp) between 6,000 and 6,500 rpm. The engine also produces 750 Nm (553 ft lb) of torque from just 2,200 rpm, which is 70 Nm more than BMW’s previous generation of SUVs produced.  Read More

The ScanEagle 2 boasts a reciprocating internal combustion engine propulsion system specia...

Since its first flight in June 2002 and introduction to the US Navy in 2005, the ScanEagle UAV developed by Boeing subsidiary Insitu has received a steady stream of improvements, including a short-wave infrared (SWIR) camera and Synthetic Aperture Radar (SAR), and clocked up over 800,000 combat flight hours over land and sea. Now Insitu has announced the next generation of the platform in the form of the ScanEagle 2.  Read More

A 3D printed titanium implant has replaced the heel bone of a 71-year-old cancer  (Photo: ...

Slowly but surely, 3D printing is working its way through the human anatomy, replacing infected jaws, cancerous vertebrae and deformed hips in a procession of world-first medical treatments. The latest body part to be ticked off the list is the heel, putting a 71-year-old cancer patient who was facing an amputation below the knee back on his feet.  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
