Phase-change materials (PCMs) are capable of storing or releasing a substantial amount of thermal energy within a small volume through the latent heat of fusion during phase transitions of melting and solidification, i.e., from solid to liquid or vice versa, in a near...
Récemment, un ressort en titane imprimé en 3D s’est déployé à bord d’un petit vaisseau commercial, le Mercury One. Mais quelle est cette curiosité du Jet Propulsion Laboratory (JPL) de la NASA ? Quelle est son utilité ? Pourquoi un tel projet ? Pour l’agence spatiale...
Spaceborne power systems must operate reliably for decades with minimal maintenance. Thermoelectric generators (TEGs) are intrinsically suited to long-lived missions, but their output remains constrained by available thermal gradients and the limitations of bulk...
This paper presents a test setup for evaluating Internet of Things (IoT) nodes used in pre-launch satellite qualification, with a focus on a temperature aware power manager (PM). The PM dynamically routes energy between a battery and a supercapacitor, entering a...
Le 3 février dernier, alors que le satellite Mercury One survolait la Terre, un petit boîtier a libéré un ressort en titane d’un mouvement simple mais disruptif. Il s’agissait du JPL Additive Compliant Canister (JACC), une démonstration technologique du Jet Propulsion...
Low Earth Orbit (LEO) satellite communication systems have evolved into a critical component of global broadband networks, enabling wide-area connectivity, IoT services, and intelligent multilayer satellite–terrestrial integration. Despite rapid advancements in...
