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.
