Multi-domain operations, the Army's future operating concept, requires autonomous agents with learning components to operate alongside the warfighter. New Army research reduces the unpredictability of current training reinforcement learning policies so that they are more practically applicable to physical systems, especially ground robots. These learning components will permit autonomous a

The European Commission has selected a consortium of European satellite manufacturers, operators and service providers, telco operators and launch service providers to study the design, development and launch of a European-owned space-based communication system. The study will assess the feasibility of a new initiative aiming to strengthen European digital sovereignty and provide secure co

Some of the best entertainment at the airport is all the action outside the window. Loaded luggage carriers zip past on their way to planes. Fuel trucks come and go. Catering trucks restock galleys. During winter, de-icing crews and snowplows add to the bustle. This organized chaos is overseen by the ground-control managers as part of an airport-wide effort to ensure the safety of all grou

For its 10th and final launch of the year, Arianespace used a Soyuz rocket to orbit the CSO-2 defense and security observation satellite for the French CNES space agency (Centre National d'Etudes Spatiales) and DGA defense procurement agency (Direction generale de l'armement), on behalf of the French armed forces. With this launch, Arianespace has once again demonstrated its ability to ens

In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started to thaw the permafrost beneath it, exposing billions of tons of organic matter to microbial breakdown. The decomposing organic matter began producing CO2 and CH4, two of the most important greenhouse gases. Thoug

Since CO2 has been recognized as the most important anthropogenic greenhouse gas owing to its significant impact on global warming and climate change, there have been a substantial number of studies that have focused on investigating the status of CO2 in the atmosphere in the past and present, and how it will change in the future. The United Nations Climate Change Conference (24th Conferen

A fast, green and one-step method for producing porous carbon spheres, which are a vital component for carbon capture technology and for new ways of storing renewable energy, has been developed by Swansea University researchers. The method produces spheres that have good capacity for carbon capture, and it works effectively at a large scale. Carbon spheres range in size from nanomete

Analytical optical methods are vital to our modern society as they permit the fast and secure identification of substances within solids, liquids or gases. These methods rely on light interacting with each of these substances differently at different parts of the optical spectrum. For instance, the ultraviolet range of the spectrum can directly access electronic transitions inside a substance wh

A diamond lasts forever, but that doesn't mean all diamonds have a common history. Some diamonds were formed billions of years ago in space as the carbon-rich atmospheres of dying stars expanded and cooled. In our own planet's lifetime, high-temperatures and pressures in the mantle produced the diamonds that are familiar to us as gems. 5,000 years ago, a large meteorite that struck a carbon-rich

WASHINGTON — SpaceX has been awarded a $150.4 million contract to launch as many as 28 satellites for the Pentagon’s space agency, the Defense Department announced Dec. 31. 

The contract is to launch a mix of small and medium spacecraft of different sizes that the Space Development Agency is acquiring from multiple vendors.
