White streaks are sometimes observed in the wake of aircraft. In some cases, these can turn into cirrus clouds which, depending on their persistence in the atmosphere, can alter the planet's radiation balance and possibly contribute to global warming. While certain local humidity and temperature conditions are required for the formation of these trails, the […]
The James Webb Space Telescope is the largest and most powerful telescope ever launched into space. It follows in the footsteps of the Hubble Space Telescope by forming the next great space science observatory, designed to answer the most essential questions about the universe and make groundbreaking discoveries in all fields of astronomy. It was […]
Par Jean-Christophe Lambert, Cofounder & CEO, Ascendance L’objectif de la neutralité́ carbone des avions, fixé à l’horizon 2050, ne pourra être atteint sans une collaboration étroite entre compagnies aériennes, fournisseurs d’énergies, industriels, organismes publics de R&D et startups. Là où les compagnies aériennes, bridées par leur legacy, travaillent sur des projets à moyen et long […]

By Nicolas Jeuland, Emeritus Expert on the Environmental Impact of Aviation and Future Fuels, Safran, AAE correspondent (lecture in french) The aviation industry is committed to carbon neutrality by 2050. To achieve this, the aviation industry is working on 3 main levers: the constant improvement of the fleet's energy efficiency, in particular through the development […]
The job of test pilot is a "small job". There must be fewer than a hundred active test pilots in France. Some work for the state, within DGA EV, others for manufacturers: Airbus, Dassault, Daher. Of course, it is a question of trying prototypes that have never flown, but also derived, modified or new configurations. […]
By Alexis Rouillard, CNRS researcher, IRAP Why is the Sun's atmosphere two hundred times hotter than its surface? How are solar winds and thunderstorms created? To answer these major questions in astrophysics, the Parker Solar Probe and Solar Orbiter space probes set out in 2018 and 2020 to discover the environment close to the Sun: […]
