Oak Ridge Scientists Eliminate Industrial Molds Using Advanced Origami Printing
Researchers at the U.S. Department of Energy’s Manufacturing Demonstration Facility at Oak Ridge National Laboratory have introduced an innovation in additive manufacturing by integrating origami-inspired 3D printing techniques with hybrid composites - materials made...
Tout savoir sur l’impression 3D de bois
Lorsque l’on parle de fabrication additive et de matériaux, on pense souvent aux plastiques ou aux métaux. Toutefois, l’offre actuellement proposée s’est largement étoffée au fil des années et nous pouvons désormais produire des pièces avec une grande variété de...
Airbus Helicopters touts U145 concept as armed ‘drone mothership’ platform
Uncrewed rotorcraft pitched at utility and ‘drone mothership’ applications. Airbus Helicopters displayed its recently-revealed U145 uncrewed rotorcraft concept at the ILA Berlin air show, highlighting two of its potential future operational applications. With its...
UAV Multi-Aircraft Collaborative Inspection Track Planning in Complex Dynamic Environments
To address the problems of state estimation bias, dynamic threat response lag, and insufficient safety margin in formation coordination caused by the mismatch between the three-dimensional continuous motion model and the discrete sampling characteristics of sensors in...
Why Orbital Data Centers Are Harder Than Silicon Valley Thinks
“Space computing, the final frontier, has arrived,” Nvidia CEO Jensen Huang declared at the Nvidia GTC conference in March. Indeed, the idea of data centers in orbit has gone from science fiction to a serious spending category. Elon...
Décollage réussi d’une fusée H3, fleuron du programme spatial japonais, avec six petits satellites à bord
Une fusée H3, fleuron du programme spatial japonais, a été lancée avec succès, vendredi 12 juin, avec six petits satellites à son bord, selon des images diffusées en direct par l’Agence d’exploration aérospatiale japonaise (JAXA). « La combustion du deuxième étage, le...
Space-Based GNSS Radio Frequency Interference Detection Evaluation Through Multi-Satellite Data Integration
Space-based GNSS reflectometry (GNSS-R) can detect terrestrial radio frequency interference (RFI) through elevated noise power in delay-Doppler map forbidden zones. This study evaluates how constellation size affects detection performance using Level 1 delay-Doppler...
TTP Satellite Modem Module Targets Smooth Network Transition to 5G NTN
TTP plc, an independent technology and product development services company, is developing a 5G non-terrestrial networks (NTNs) modem module. Designed to form the core of future satellite solutions, including Ku- and Ka-Band terminals, the new modem architecture...
Wind-assisted propulsion: Managing safety while regulation takes shape
As wind-assisted propulsion scales across the global fleet, operations are advancing faster than regulation. With IMO guidance still under development, safety today rests on strong operational practice, class approval, and the ISM Code. Wind-assisted propulsion...
Un atome acoustique sur puce imite le comportement des électrons
Des chercheurs de Virginia Tech ont mis au point un dispositif à l’échelle d’une puce capable de piéger et de contrôler des ondes sonores à des niveaux d’énergie discrets, reproduisant le comportement d’un atome. Publiée dans Physical Review Letters, l’étude ouvre des...
