Earth’s gravitational field affects everything in materials science research. It drives convection currents in solutions, causes denser particles to sediment out of suspensions, forces immiscible phases to separate by density, and deforms soft or liquid samples...
To meet the need for global coverage, space–air–ground integrated networks (SAGINs) are crucial, but the openness of wireless links makes communications vulnerable to eavesdropping. This paper investigates the physical layer security (PLS) of uplink transmissions in a...
Terriennes, Terriens, vous avez été très nombreuses et nombreux à suivre ce direct consacré au survol de la Lune par Artemis-2 après plus d’un demi-siècle sans mission habitée lunaire. Nous souhaitons un bon retour parmi nous à Reid Wiseman, Victor Glover, Christina...
An international research team boarded ESA’s 86th parabolic flight campaign in May 2025 with ultralight graphene aerogels, then hit them with light during zero gravity phases to observe their reaction under space-like conditions. Inside a vacuum chamber, a continuous...
NXGSAT, in partnership with ETL Systems, has successfully demonstrated an interoperable, fully productised 5G non-terrestrial network (NTN) solution, combining NXGSAT’s software-defined 5G NTN user equipment (UE) modem with ETL’s GENUS Digital platform, integrated...
Extreme thermal shock in space exploration poses a critical threat to orbital spacecraft, as conventional thermal protection structures cannot concurrently resist concentrated thermal effects under shock and ensure efficient heat dissipation during routine operation....
