The frequency regime lying in the shortwave infrared (SWIR) has very unique properties that make it ideal for several applications, such as being less affected by atmospheric scattering as well as being “eye-safe.” These include Light Detection and Ranging (LIDAR), a method for determining ranges and distances using lasers, space localization and mapping, adverse weather imaging for surveillance and automotive safety, environmental monitoring, and many others.

However, SWIR light is currently confined to niche areas, like scientific instrumentation and military use, mainly because SWIR photodetectors rely on expensive and difficult-to-manufacture materials. In the past few years, —solution-processed semiconducting nanocrystals—have emerged as an alternative for mainstream consumer electronics.

While toxic heavy-metals (like lead or mercury) have typically been used, quantum dots can also be made with environmentally friendly materials such as silver telluride (Ag2Te). In fact, silver telluride colloidal quantum dots show device performance comparable to their toxic counterparts. But they are still in their infancy, and several challenges must be addressed before they can be used in practical applications.

“No two ways about it,” Altepeter told Breaking Defense today. “The number of companies that we’re announcing is a surprise to me. I did not expect we would get this many.”

For the winning teams, the value of QBI is not just the money. Indeed, first-round grants like those being announced today have typically been under $1 million — small change not just for the Pentagon but for tech firms and venture capitalists already investing billions into quantum ventures. We suggested everybody apply for a million, [but] some people came in and said they were going to do it for less, Altepeter said.

The unique value of a QBI award is that it gives the winning companies access to a DARPA-led team of quantum experts, pulled from both US government labs, including the famous Los Alamos, and federally funded research institutions. Their job is to act as independent testers, fresh eyes, and devil’s advocates, rigorously scrutinizing each participant’s quantum strategy.

🚀 Q: What key capabilities must SpaceX perfect for Earth-to-Earth transportation? A: SpaceX must master in-space engine relight, Mechazilla catch system landings, and re-entry with V2 upgrades including improved flaps and heat shields for extreme conditions.

🛬 Q: How many Starship landing pads is the US Air Force planning to build? A: The USAF plans to construct two landing pads on Johnston Island, with potential for more in the future, emphasizing goals of high launch frequencies and seamless point-to-point transport.

What if we told you AI just created the strongest light material known to humanity? This groundbreaking discovery could revolutionize everything from aerospace to everyday tech.

Researchers from the U.S. Army Research Laboratory (ARL) and Lehigh University have developed a nanostructured copper alloy that could redefine high-temperature materials for aerospace, defense, and industrial applications.

Their findings, published in the journal Science, introduce a Cu-Ta-Li (copper-tantalum-lithium) alloy with exceptional thermal stability and , making it one of the most resilient copper-based materials ever created.

“This is cutting-edge science, developing a new material that uniquely combines copper’s excellent conductivity with strength and durability on the scale of nickel-based superalloys,” said Martin Harmer, the Alcoa Foundation Professor Emeritus of Materials Science and Engineering at Lehigh University and a co-author of the study. “It provides industry and the military with the foundation to create new materials for hypersonics and high-performance turbine engines.”

Last month, DARPA published a call for proposals on how to “grow” massive biological structures in space. It’s not as crazy as it sounds: The space race is heating up outside of the weird space biology sector. Some startups are building self-assembling space habitats, others are working on spaceports, and the ISS’s successor is in development. Let’s take a look.

At hypersonic speeds, complexities occur when the gases interact with the surface of the vehicle, such as boundary layers and shock waves. Researchers in the Department of Aerospace Engineering at The Grainger College of Engineering, University of Illinois Urbana-Champaign, were able to observe new disturbances in simulations conducted for the first time in 3D.

The study, “Loss of axial symmetry in hypersonic flows over conical shapes,” is published in Physical Review Fluids.

Fully 3D simulations require a great deal of processing power, making the work expensive to compute. Two things made it possible for Deborah Levin and her Ph.D. student Irmak Taylan Karpuzcu to conduct the research: Time on Frontera, the leadership-class computer system at the Texas Advanced Computing Center and software developed in previous years by several of Levin’s former graduate students.
