  Lockheed Martin Reveals New Human Lunar Lander Concept

  DENVER, Oct. 3, 2018 /PRNewswire/ -- Today, at the International Astronautical Congress (IAC) in Bremen, Germany, Lockheed Martin (NYSE: LMT) experts revealed the company's crewed lunar lander concept and showed how the reusable lander aligns with NASA's lunar Gateway and future Mars missions. Concept video: https://vimeo.com/293133933 Lockheed Martin Crewed-Lunar-Lander The crewed lunar lander is a single stage, fully reusable system that incorporates flight-proven technologies and systems from NASA's Orion spacecraft. In its initial configuration, the lander would accommodate a crew of four and 2,000 lbs. of cargo payload on the surface for up to two weeks before returning to the Gateway without refueling on the surface. "NASA asked industry for innovative and new approaches to advance America's goal of returning humans to the Moon, and establishing a sustainable, enduring presence there," said Lisa Callahan, vice president and general manager of Commercial Civil Space at Lockheed Martin Space. "This is a concept that takes full advantage of both the Gateway and existing technologies to create a versatile, powerful lander that can be built quickly and affordably. This lander could be used to establish a surface base, deliver scientific or commercial cargo, and conduct extraordinary exploration of the Moon." The unique orbit of the lunar Gateway provides global lunar access for a lander. Having the ability to visit multiple sites with a reusable lander supports many international, commercial, and scientific communities, in addition to NASA's sustainable exploration of the Moon. After a surface mission, it would return to the Gateway, where it can be refueled, serviced, and then kept in orbit until the next surface sortie mission. "The Gateway is key to full, frequent and fast reusability of this lander," said Tim Cichan, space exploration architect at Lockheed Martin Space, who presented the lander concept at IAC. "Because this lander doesn't have to endure the punishment of re-entering Earth's atmosphere, it can be re-flown many times over without needing significant and costly refurbishment. That's a major advantage of the Gateway and of a modular, flexible, reusable approach to deep space exploration." The investments made in technology developed for Orion can be re-used to reduce the cost, complexity and development timeline. Some of the human-rated, flight-proven systems used in the design include avionics, life support, communications and navigation systems, and a light-weight version of its crew module pressure vessel. Reusable landers are enabled by the lunar Gateway and are important for sustainable exploration. Additionally, landed human lunar missions and a lunar orbiting outpost are valuable to prepare for sending humans to Mars. While the Moon doesn't have an atmosphere, there are still many lessons that apply to a future crewed Mars lander, such as: operations experience in a challenging and dynamic environment, operating and refueling out of orbit, long-duration cryogenic propulsion, and terminal descent navigation, guidance and control.

  Qu’est-ce que la Base industrielle et technologique de défense (BITD) ?

  DEFENSE Qu'est-ce que la Base industrielle et technologique de défense (BITD) ? Selon L'Opinion, l'ancien candidat LREM à la mairie de Paris et porte-parole du gouvernement Benjamin Griveaux se serait vu confié en tant que député une mission sur la « Base industrielle et technologique de défense » (BITD). Durant deux mois, il serait chargé avec le député Les Républicains Jean-Louis Thieriot de se pencher sur la place des industries de défense dans le plan de relance post-Covid-19. L'occasion pour l'Usine Nouvelle d'expliquer dans un article ce qu'est la BITD. L'Observatoire économique de la Défense, rattaché au ministère des Armées, établit chaque année cette Base industrielle et technologique de la défense. Elle regroupe l'ensemble des entreprises contribuant directement ou indirectement à la production ou au maintien en condition opérationnelle des armements : elles sont soit fournisseurs directs du ministère des Armées, soit sous-traitants des grands maîtres d'oeuvre industriels de la Défense. En 2018, il s'agissait d'une dizaine de grands groupes de taille mondiale (groupe Airbus, Dassault Aviation, Naval Group, MBDA, Nexter, Safran, Thales...) et 4 000 PME, soit environ 200 000 emplois, qui étaient comptabilisés.
