The study helps to confirm the idea that the surface of Phobos contains tons of dust, soil, and rock blown off the Martian surface by large projectile impacts. Phobos' orbital path plows through occasional plumes of Martian debris, meaning the tiny moon has been gathering Martian castoffs for millions of years.
Son of Blackbird: Lockheed Martin's Skunk Works has recently revealed its plans for a hypersonic aircraft that will go twice the speed of the SR-71. The SR-72 twin-engine aircraft is expected to travel at Mach 6, with the ability to strike targets. At this speed, no enemy would have time to react or hide.
The European Space Agency says one of its research satellites re-entered the Earth's atmosphere early Monday on an orbit that passed over Siberia, the western Pacific Ocean, the eastern Indian Ocean and Antarctica. The 1,100-kilogram (2,425-pound) satellite disintegrated in the atmosphere but about 25 percent of it...
Narrow stripes of dirt and rock beneath massive Antarctic glaciers create friction zones that slow the flow of ice toward the sea, researchers at Princeton University and the British Antarctic Survey have found. Understanding how these high-friction regions form and subside could help researchers understand how the flow of these glaciers responds to a warming climate.
Every so often, you see a robot on the internet that is so macabre-looking it belongs in a horror film. There is a quality about these robots that’s not quite robot, but not quite human. Generally, in the technology community, nine out of ten of these robots come out of the Department of Defense sponsored Defense Advanced Research Projects Agency (a.k.a DARPA). (If you need proof, check out DARPA’s PETMAN)
The handheld mortar has long been a staple for the U.S. Marine Corps, and yesterday the weapon got a major boost as combat instructors at Marine Corps Base Quantico successfully conducted a live-fire demonstration of a new mortar sight, sponsored by the Office of Naval Research (ONR).
Dr. Evil would be proud. Lasers have always been the next frontier (some would say pipe dream) of weapons development. But recent developments have brought Sci-Fi closer to reality. And now this — the Pentagon has awarded a total of $26 million to defense contractors to develop a laser countermeasures system for manned and unmanned aircraft.
TE Connectivity announces the new VITA 66.1 Ruggedized Optical Backplane interconnect system that has been designed to meet the needs of high-bandwidth applications such as for high-definition video and images and more specifically for computing applications requiring optical infrastructure.
India on Tuesday launched its first spacecraft bound for Mars, a complex mission that it hopes will demonstrate and advance technologies for space travel. Hundreds of people watched the rocket carrying the Mars orbiter take off from the east-coast island of Sriharikota and streak across the sky. Many more across the country watched live TV broadcasts.
In aviation, it doesn’t get more chic than the SR-71 Blackbird, the Rolls Royce of the sky. From 1964 till its retirement in 1998, this supersonic, Mach 3+ reconnaissance aircraft played a crucial role in the Cold War (and afterward) for over three decades. But ever since the Blackbird went to the Boca Raton of the skies, aviation buffs have been pining for a successor. And now they have one. And it’s glorious.
The Behlman FC5003 is an ultra-rugged COTS power supply designed to convert common 120/208 VAC, 3-phase, 60 Hz ground power to 115/200 VAC, 3-phase 400 Hz power used by aircraft and other vehicles, and equipment that require 400 Hz.
Voltage-controlled crystal oscillators offer a wide choice of frequency, voltage, and output combinationsNovember 4, 2013 12:52 pm | Rfmw Ltd | Product Releases | Comments
RFMW, Ltd. announces design and sales support for Sunny Electronics SVP-53 series of FastClock voltage controlled crystal oscillators (VCXO’s). The SVP-53 series of FastClock VCXO’s is available in a CMOS output waveform and comes in a standard 5x3.2mm package.
Using an in-orbit robot to capturing a malfunctioning satellite that is tumbling out of control is currently just a theoretical idea. However, research inspired by nature to be published in the forthcoming issue of International Journal of Mechanisms and Robotic Systems, could take us a small step towards making such science fiction science fact.
Comtech Xicom Technology announces new military satellite communication (MIL-SATCOM) solid-state power amplifier block upconverters will be presented during MILCOM'13. At MILCOM’13, Xicom will be showcasing its new generation of 50-Watt X-Band and 40-Watt Ku-Band solid-state high power amplifiers (SSPAs).
AVX Corporation has expanded its Mini-TurboCap and RoHS Compliant Mini-TurboCap Series with a new 25V rating and an extended capacitance range (up to 39µF) for its 50V parts. Now available in 25V, 50V, and 100V, these state-of-the-art base metal electrode (BME) capacitor series exhibit extremely high volumetric efficiency....
The F-35 Lightning II program, which surpassed 10,000 flight hours in September, has another reason to celebrate today. On October 31, the F-35A, a 5th generation fighter, successfully launched an AIM-120 radar-seeking missile from the internal weapons bay.
U.S. government safety rules are changing to let airline passengers use most electronic devices from gate-to-gate. The change will let passengers read, work, play games, watch movies and listen to music — but not make cellphone calls. The Federal Aviation Administration says airlines can allow passengers to use the devices during takeoffs and landings...
Richardson RFPD today announces availability and full design support capabilities for a new 28V gallium nitride-on-silicon (GaN-on-Si) RF power amplifier from Nitronex. The NPA1006 is a wideband GaN power amplifier optimized for 20 to 1000 MHz operation.
The CPC1968 is a single-pole normally open (1-Form-A) solid-state power relay rated for up to 5A continuous load current with a 5°C/W heat sink. The output is constructed with MOSFET switches and photovoltaic die, while the input utilizes a highly efficient GaAIAs infrared LED to provide the optically coupled control.
A recently released video of Iran’s new “suicide remotely piloted vehicle” called the Ra’ad 85—aka Thunder 85—reveals it might be less impressive than originally announced. A few weeks ago, Brigadier General Ahmad Reza Pourdastan, Commander of the Iranian Army Ground Force, announced the Ra’ad 85 would be a game-changer for Iran’s military.
