The ExoMars 2016 Trace Gas Orbiter (TGO) and an ESA-built EDM stationary lander called ‘Schiaparelli’ will be launched in March 2016. The TGO will deliver the stationary lander and then proceed to map the sources of methane and other gases on Mars, and in doing so, will help to select the landing site for the ExoMars 2018 rover (to be launched in 2018 on a Russian heavy lift Proton launch vehicle).

When aircraft manufacturers started to install just two seats instead of three in airliner cockpits in the 1980s, this was something of a mini-revolution. Since that time, planes have generally been flown by just the pilot and co-pilot.

The Meteosat program finds its origin in 1977 when the first prototype satellite was launched to explore the technologies needed to acquire meteorological data from Geostationary Orbit. Two more prototype satellites were launched in 1981 and 1988 before the first operational satellite, Meteosat-4, launched in 1989. As part of the Meteosat Operational Program, three satellites were launched followed by Meteosat-7 in 1997 as part of the Meteosat Transition Program that was implemented to bridge the gap between the first and second generation of Meteosat spacecraft by launching one improved first generation satellite.

The Orion mission, an ESA/NASA cooperative project, will be the next manned vehicle beyond Low Earth Orbit (LEO) and will enable manned missions to the Moon, Mars and asteroids. The new vehicle will be propelled by a service module based on the design and experience gained with the ATV, the ISS supply spacecraft with centralized procurement of the electronic components, in which Alter Technology participated for almost 10 years.

The space probe Rosetta was built by the European Space Agency (ESA ) with the objective of reach and study Comet 67P/Churyumov-Gerasimenko. Was launched on March 2004 from Kourou. To place it on the required orbit to rendezvous with Comet 67P/ Churyumov-Gerasimenko it received four gravity assist manoeuvres: 3 from Earth (4 March 2005, 13 November 2007 and 13 November 2009) and 1 from Mars (25 February 2007).

The HTV vehicle is an unmanned spacecraft that in an autonomous way is able to supply food, replacement parts, test equipment and other items to the crew of the ISS. The “brain” of this vehicle – it is Avionic Module – was developed by Mitsubishi Electric. Currently, several launches of this ship are planned in addition to the 6 (HTV-1, HTV-2, HTV-3, HTV-4, HTV-5 and HTV-6) made to date.

Crimping together with wire wrapping and spring clip systems are the preferred alternatives for the solderless connection of electrical conductors. In particular, crimped connectors offer several advantages such as: Gas-tightness and protection against oxidation and corrosive environments, High mechanical strength is inherent to the lack of alloys in the mechanical joint, Large versatility in terms of the wire diameters.
