Funded by the Air Force Research Labs (AFRL), Ursa Major first introduced the 4,000lb thrust closed-cycle engine in May 2023, with the ultimate goal of having a fully operational engine that can operate in the atmosphere or outer space by the end of 2024. According to a company statement, this successful May test firing puts the development of Draper ahead of schedule, “outpacing industry standards.” “We’re excited with how quickly the development program...

The robotic drone is performing classified duties during the program’s fifth flight. The current mission — known as Orbital Test Vehicle (OTV-5) — was rocketed into Earth orbit on Sept. 7, 2017, atop a SpaceX Falcon 9 booster from Launch Complex 39A at NASA’s Kennedy Space Center (KSC) in Florida. [The X-37B X-37B missions are carried out under the auspices of the Air Force Rapid Capabilities Office, and mission control for OTV flights is handled by the 3rd Space ... gathering information on objects high above Earth and carrying out other intelligence-gathering duties. And that may be a signal as...

Almost 2,000 Sony PlayStation game consoles have been networked by the U.S. Air Force Research Laboratory (AFRL) to create an affordable supercomputer that is being used to develop techniques to process and analyze huge quantities of imagery from wide-area surveillance systems. The Condor Cluster created by AFRL’s Information Division at Rome AFB, N.Y., comprises 1,760 PlayStation 3 consoles and 168 high-performance graphics processors connected by a high-bandwidth network. The cluster has a peak performance of 500 teraflops (trillion floating-point operations per second). Built for about $2 million, the Condor is the 34th most powerful supercomputer in the world, but it...

When US Air Force researchers last year created the mother-of-all-processors using Sony PlayStation-3 game consoles, it seemed like a stroke of cost-saving genius.To deliver a 53-TerraFLOP processing cluster, the Air Force Research Laboratory in Rome, N.Y., hoovered up 1,700 PlayStation-3 game consoles, then harnessed the power of their combined processors to evaluate new breakthroughs in technology for synthetic aperture radar, high definition video and something called "neuromorphic computing". At the time, the researchers noted that two PlayStation-3 consoles provide 150 GigaFLOPs of processing power for $600, but a single 3.2GHz cell processor delivers 200 GFLOPs for $8,000. Why spend the...
