DARPA recently awarded five contracts and selected one Government partner to develop technology to capture potable water from the air in quantities sufficient to meet critical DoD needs, even in extremely dry climates. GE Research, Physical Sciences Inc., Honeywell International Inc., Massachusetts Institute of Technology, University of Texas at Austin, and U.S. Naval Research Laboratory were chosen to develop next-generation, scalable sorbent materials and prototypes under DARPA’s Atmospheric Water Extraction (AWE) program.

The goal of the AWE program is to provide fresh water for a range of military, stabilization, and humanitarian needs through the development of small, lightweight, low-powered, distributable systems that extract moisture from the atmosphere. DARPA is open to various approaches, with an emphasis on advanced sorbents that can rapidly extract water from ambient air and release it quickly with minimal energy inputs. These sorbent materials offer potential solutions to the AWE challenge, provided they can be produced at the necessary scale and remain stable over thousands of extraction cycles. In addition to developing new sorbents, AWE researchers will need to engineer systems to optimize their suitability for highly mobile forces by substantially reducing the size, weight, and power requirements compared to existing technologies.

“Access to clean water is of critical importance to the warfighter, and current water distribution operations incur numerous financial, maintenance, and logistical challenges,” noted Dr. Seth Cohen, AWE program manager. “The selected AWE program performers are being asked to leverage advanced modeling, innovative engineering, and additive manufacturing methods to support the program, which in turn will help maintain combat readiness, reduce casualties and cost due to water transportation, and enhance humanitarian and disaster relief efforts.”

A DARPA network technology program recently concluded field tests demonstrating novel software that bridges multiple disparate radio networks to enable communication between incompatible tactical radio data links – even in the presence of hostile jamming. The technology is transitioning to Naval Air Systems Command (NAVAIR) and the Marine Corps, which plans to put the software on a software reprogrammable multi-channel radio platform for use on aircraft and ground vehicles.

Started in 2016, the Dynamic Network Adaptation for Mission Optimization program, or DyNAMO, has developed technologies that enable automated, real-time dynamic configuration of tactical networks to ensure that heterogeneous radio nodes – whether on ground, air, or sea – can interoperate in a contested battlespace.

As a capstone event to conclude the program, DARPA recently demonstrated DyNAMO capabilities in over-the-air field tests at the Air Force Research Lab’s experimentation and test facility near Rome, New York. Diverse military tactical data links, including LINK 16, Tactical Targeting Networking Technology (TTNT), Common Data Link (CDL), and Wi-Fi networks were deployed to the test site. DyNAMO successfully provided uninterrupted network connectivity between all the data links under varying conditions in a simulated contested environment.

New initiative aims to lower high barrier to entry for resource-constrained organizations, increasing access to participate in forward-looking research.

As the world continues to change and advance at a rapid pace, the need for continuous innovation has never been greater. DARPA’s open innovation model leverages the expertise and novel ideation found in large and small businesses, government organizations, and academic institutions. However, resource constraints across these organizations can limit their participation in cutting-edge research opportunities. Within the microelectronics arena in particular, skyrocketing costs for designing integrated circuits are stifling participation in the innovation process.

To help remove potential roadblocks to further increasing the speed of innovation, the agency today announced DARPA Toolbox – a new, agency-wide effort to provide open licensing opportunities with commercial technology vendors to the researchers behind DARPA programs. Through DARPA Toolbox, successful proposers will receive greater access to commercial vendors’ technologies and tools via pre-negotiated, low-cost, non-production access frameworks and simplified legal terms. For commercial vendors, DARPA Toolbox will provide an opportunity to leverage the agency’s forward-looking research and a chance to develop new revenue streams based on programmatic achievements developed with their technologies.

“DARPA performers are frequently encumbered by having to negotiate access to tools, IP, and services, and execute complex legal agreements that take the time away from what they do best – advancing science to benefit the nation,” said Serge Leef, the Microsystems Technology Office (MTO) program manager spearheading this effort. “Through DARPA Toolbox, we are working to effectively lower the high barrier to entry with the goal of encouraging more proposals from non-traditional and resource-constrained organizations that can bring innovative insights and ideas to bear on DARPA programs.”

Attempts at airborne retrieval of three unmanned air vehicles, nicknamed Gremlins, were just inches from success in DARPA’s latest flight test series that started on October 28. Each X-61A Gremlins Air Vehicle (GAV) flew for more than two hours, successfully validating all autonomous formation flying positions and safety features. Nine attempts were made at mechanical engagement of the GAVs to the docking bullet extended from a C-130 aircraft, but relative movement was more dynamic than expected and each GAV ultimately, safely parachuted to the ground.

“All of our systems looked good during the ground tests, but the flight test is where you truly find how things work,” said Scott Wierzbanowski, program manager for Gremlins in DARPA’s Tactical Technology Office. “We came within inches of connection on each attempt but, ultimately, it just wasn’t close enough to engage the recovery system.”

Hours of data were collected over three flights, including aerodynamic interactions between the docking bullet and GAV. Efforts are already underway to analyze that data, update models and designs, and conduct additional flights and retrieval attempts in a fourth deployment this spring.

DARPA Looks to Light up Integrated Photonics with Chip-Scale Laser DevelopmentAgency announces performer teams selected for LUMOS program.

First demonstrated sixty years ago, the laser has become an essential technology in today’s world. It has transformed diverse fields including communications, sensing, manufacturing, and medicine. More recently, innovations in integrated photonics have allowed the miniaturization of key optical components and the ability to arrange several elements on a single silicon chip. When combined with lasers, these photonic integrated circuits (PICs) have the potential to replace large and costly optical systems with chip-scale solutions. However, due to differences in the properties of the materials that compose them, lasers and PICs are difficult to combine onto the same platform, limiting the benefits of integration and preventing broad technology impact.

To address this challenge, DARPA developed the Lasers for Universal Microscale Optical Systems (LUMOS) program, which aims to bring high-performance lasers to advanced photonics platforms. As highlighted in the recent program kick-off meeting, LUMOS will address several commercial and defense applications by directing efforts across three distinct Technical Areas.

The first LUMOS Technical Area brings high-performance lasers and optical amplifiers into advanced domestic photonics manufacturing foundries. Two research teams were selected in this area: Tower Semiconductor and SUNY Polytechnic Institute. These performers will work to demonstrate flexible, efficient on-chip optical gain in their photonics processes to enable next-generation optical microsystems for communications, computing, and sensing. LUMOS technologies will be made available to future design teams through DARPA-sponsored multi-project wafer runs.

Eighty-six years since electron crystals were first proposed, physicists have now constructed them, trapping electrons in a repeating pattern. The achievement is reported in the journal Nature.

A crystal is made of a repeating pattern of particles but electrons are difficult to keep in place. So an electron crystal is like trying to organize a large number of electrons that won’t stay still — it’s the herding cats of particle physics.

However, this team had an ingenious solution. They built a Wigner crystal using layers of semi-conductors just one atom thick. They then used two different tungsten materials and created a hexagonal pattern known as a moiré superlattice by placing one material on top of the other.

Capturing energy from the Sun with solar panels is only half the story – that energy needs to be stored somewhere for later use. In the case of flow batteries, storage is relegated to vats of liquid. Now, an international team led by University of Wisconsin-Madison scientists has created a new version of these solar flow batteries that’s efficient and long-lasting.

To make the new device, the team combined several existing technologies. It’s a silicon/perovskite tandem solar cell, paired with a redox flow battery, which the team says will allow people to harvest and store renewable energy in one device. Not only is it efficient, but it should be inexpensive and simple enough to scale up for home use.

The energy-harvesting part of the equation combines the long-time industry-leading material – silicon – with a promising young upstart called perovskite. These tandem solar cells have proved better than either material alone, since the two materials capture different wavelengths of light.

A new “transforming” rover in development at NASA will be able to explore rough terrain unlike any rover before it.

DuAxle (short for dual-Axel) gets its name because it’s made of a combination of a pair of two-wheeled Axel rovers. The Axel rover is a simple, two-wheeled rover with a long tether that connects to a larger vehicle and stabilizes the rover as it descends into and explores craters that other rovers would not be able to handle. The Axel is equipped with a robotic arm that can collect samples, as well as stereoscopic cameras to gather imagery.
