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.

The ESA (European Space Agency) named this satellite as Aeolus, coming from Greek mythology, Eolo (in Greek), is known as the father of the race eolia, the lord and god of the winds. What is intended with this satellite is to gather accurate information about the winds, not achieved so far. Becoming the first satellite to do it directly from space and collecting the necessary information to understand how the winds, atmospheric pressure, temperature and humidity are related, in a layer of 30,000 meters from the surface of the Earth.
