SpaceX is preparing to conduct a national security mission for the United States Space Force. The aerospace company is tasked to deploy the military’s fourth new-generation series Global Positioning System satellite, known as GPS-III Space Vehicle 04. On October 2nd, SpaceX attempted to launch the satellite to orbit but at around two seconds before the 9:43 p.m. EDT liftoff time, launch controllers aborted the launch at Cape Canaveral Air Force Station’s Launch Complex 40.

During the Live broadcast of the launch attempt the Principal Integration Engineer at SpaceX John Insprucker said the next launch opportunity for this mission is on Saturday, October 3rd at 9:39 p.m. EDT. but the rocket did not attempt a second launch because SpaceX found issues on one of the Falcon 9 rocket’s nine Merlin 1D engines. According to SpaceX founder and Chief Executive Officer Elon Musk, the Falcon 9 rocket carrying the GPS-III satellite experienced an “unexpected pressure rise in the turbomachinery gas generator,” he wrote. “… We’re doing a broad review of launch site, propulsion, structures, avionics, range & regulatory constraints this weekend. I will also be at the Cape next week to review hardware in person,” he said early October.

SpaceX’s Vice President of build and flight reliability, Hans Koenigsmann, said during a news conference on October 28th that SpaceX engineers worked alongside the U.S. Space Force and NASA to perform a deep investigation into the issue. They came to the conclusion that the Falcon 9 engine issue was due to a residue of a “masking lacquer” designed to protect sensitive parts during anti-corrosion anodizing treatment. Koenigsmann told reporters the SpaceX vendor that performed the lacquer coating treatment failed to remove all of the lacquer afterward, causing a blockage of small vent holes for Merlin engine valves. “It’s not necessarily bad,” he said, “In most cases, it rattles the engine, and it may cause a little bit of damage to the engine. In extreme cases, it may cause more damage to the engine.” SpaceX officials announced they would fix the issue by replacing the engine. Now, SpaceX targets to deploy GPS-III Space Vehicle 04 satellite atop the Falcon 9 no earlier than Thursday, November 5th at 6:24 p.m. EDT [date is subject to change]. This mission is important for the United States because the GPS-III satellite is designed to upgrade the satellite constellation that actively provides navigation services to over 4 billion users.

As the Defense Advanced Research Projects Agency (DARPA) explores designs for a ship that could operate without humans aboard, the agency is keeping the Navy involved in the effort to ensure it progresses forward should the program’s work succeed.

While the Navy is creating unmanned surface vehicles based off designs meant for ships that could bring humans aboard, the No Manning Required Ship (NOMARS) program is the first to pursue a design that takes humans out of the calculation.

Gregory Avicola, the NOMARS program manager, told USNI News in a recent interview that DARPA has had conversations with Navy offices like PMS-406, the service’s program executive office for unmanned and small combatants, and the Surface Development Squadron, which has been tasked with developing the concept of operations for unmanned surface vehicles, since the agency started the NOMARS initiative.

Tuomas Sandholm, a computer scientist at Carnegie Mellon University, is not a poker player—or much of a poker fan, in fact—but he is fascinated by the game for much the same reason as the great game theorist John von Neumann before him. Von Neumann, who died in 1957, viewed poker as the perfect model for human decision making, for finding the balance between skill and chance that accompanies our every choice. He saw poker as the ultimate strategic challenge, combining as it does not just the mathematical elements of a game like chess but the uniquely human, psychological angles that are more difficult to model precisely—a view shared years later by Sandholm in his research with artificial intelligence.

“Poker is the main benchmark and challenge program for games of imperfect information,” Sandholm told me on a warm spring afternoon in 2018, when we met in his offices in Pittsburgh. The game, it turns out, has become the gold standard for developing artificial intelligence.

Tall and thin, with wire-frame glasses and neat brow hair framing a friendly face, Sandholm is behind the creation of three computer programs designed to test their mettle against human poker players: Claudico, Libratus, and most recently, Pluribus. (When we met, Libratus was still a toddler and Pluribus didn’t yet exist.) The goal isn’t to solve poker, as such, but to create algorithms whose decision making prowess in poker’s world of imperfect information and stochastic situations—situations that are randomly determined and unable to be predicted—can then be applied to other stochastic realms, like the military, business, government, cybersecurity, even health care.

The U.S. Army’s next-generation infantry fighting vehicle could feature German DNA. German defense contractor Rheinmetall is teaming up with American defense contractor Raytheon to offer the company’s KF41 Lynx infantry fighting vehicle to the U.S. Army. The Army is looking to replace its thousands of M2 Bradley fighting vehicles with a newer design that is not only better in every way, but also has the ability to be remotely controlled on the battlefield.

Like its key allies, the UK is increasingly reliant on space-based assets for daily life in ordinary civil society and for the perfornance of its military forces. So, the Royal Air Force’s operating domain now extends from the ground to far beyond the atmosphere.

In a lockdown summer of downbeat aviation news, it is perhaps fitting that a highlight was a model aeroplane in a windtunnel. In turbulent times for aerospace, that aircraft is even named after a storm. But in showing some detail of the external shape of the Tempest future fighter, BAE Systems has also emphasised the UK’s determination to ride out the technological, financial and geopolitical hurricanes which are set to shape the national defence challenges of the next few decades.

Those late August images from BAE’s Warton, Lancashire test facility reveal an external profile designed for stealth at Mach 2, to carry a wide range of payloads and to cope with the internal heat from enough onboard electric power to anticipate exotic technologies like laser directed-energy weapons.

Oct. 22 (UPI) — Chief of Space Operations Gen. Jay Raymond established Space Operations Command during an activation ceremony at Peterson Air Force Base in Colorado this week.

According to the Space Force, Lt. Gen. Stephen Whiting will serve as commander of the new unit, which is mostly formed from former Air Force units 14th Air Force and Air Force Space Command.

At the ceremony Wednesday, Raymond and Whiting both talked about the decades of work that made the new organization possible, and the role of that history in preparing warfighters for space.

The U.S. army will have pocket sized drones.

Nano drones have become a major military tool over the past few years, and the most recent announcement of FLIR Systems being awarded an additional $20.6 million contract for their Black Hornet 3 Personal Reconnaissance Systems (PRS) by the U.S. Army is one big example of that.

While the contract is huge, the FLIR Systems Black Hornet 3 is only the size of a cellphone. This extremely light and nearly silent drone can fly up to 25 minutes, and provide many military advantages in combat.

With this second contract, FLIR Systems will be providing the service with additional miniature reconnaissance drones as part of the ongoing soldier-borne sensor program, National Defense reports.

General Atomics Electromagnetic Systems (GA-EMS) and Boeing have entered into a partnership to develop a scalable 100 kW to 250 kW-class High Energy Laser (HEL) weapon system for air and missile defenses.

Laser weapons have been high on the wish lists of major military powers ever since the first laser was invented by Theodore Maiman at the Hughes Research Lab, Malibu, California in 1960. With enough concentrated power to burn through steel, enough range to cover literally astronomical distances, an operating cost of a dollar a shot, and an unlimited number of shots so long as there’s power available, the laser looked like the so-called ultimate weapon – if it could be made practical.

Of the problems that have hampered laser weapon development over the past six decades, one of the biggest is how to properly cool a laser generator. This is important because weapon-grade lasers have an efficiency between 50 and 70 percent, with the leftover percentages being lost as heat that could shut down or damage the device.
