Jules Verne, the first Automated Transfer Vehicle (ATV), will be launched next year by a specific version of Ariane 5 called the Ariane 5 Evolution Storable upper stage Automated Transfer Vehicle, or A5 ES-ATV for short.
Although the ATV does not use the powerful ECA version of Ariane 5, which was launched successfully into geostationary orbit in February 2005, it does need an Ariane 5 equipped with the powerful Vulcain 2 main engine, and featuring the storable propellant upper stage (Etage à Propergols Stockables or EPS) and its re-ignitable engine, the Aestus.
Some adaptations to the launcher are also necessary to ensure compatibility with the heavy ATV spacecraft and its specific delivery orbit. For the recurring flights, the launcher will inject the 20 750 kg ATV into the International Space Station orbital plane in low Earth orbit at 300 km altitude inclined 51.6 degrees above the Equator. For the first ATV mission, Jules Verne with a mass of 19 600 kg, the orbit is also slightly lower at 260 km.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
