A meeting organized by the Air and Space Academy and the Center of Aerospace Research of Sapienza, University of Rome About the decarbonisation of aviation, the conference will focus on its four main pillars: continuous performance improvement, sustainable alternative fuels, carbon capture, and ”sobriety”. The crucial development of alternative fuels raises the question of the […]
By Vincent Dubourg, Deputy Director of Balloons at CNES, Orbital Systems and Applications Division For 60 years, CNES (Centre National d'Etudes Spatiales) has been designing, developing and operating balloons to carry out scientific measurements and technological tests in the upper atmosphere. More than 4,000 flights have been operated by CNES balloon operators in all latitudes. […]
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 […]
As part of the 2024 "Rendez-vous Espace" conference cycle organised by the Friends of the Cité de l'espace in partnership with the Cité de l'espace, the Académie de l'air et de l'espace and the 3AF. Lecture presented by Delphine Leroux, head of the Hydrology, Cryosphere and Water Cycle programs at CNES and Rosemary Morrow, oceanographer […]
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: […]
This lecture dedicated to “Decarbonising Air Transport: a question of energy” and organised by the Escuela Técnica Superior de Ingeniería Aeronáutica y del Espacio (ETSIAE) and the Air and Space Academy, AAE. With the support of TEDAE y de AIAE Aviation did not wait until 2023 to start decarbonising. The International Civil Aviation Organization (ICAO) has […]
By Michel Blanc, Professor Emeritus, IRAP, University of Toulouse, Chair of the COSPAR "Panel on Exploration", fellow of the AAE Lunar exploration is the first step towards future human missions to Mars. It also has its own objectives: scientific research, exploitation of local resources, services for astronauts, and perhaps even tourism. At a time of […]
