The City of Arts and Sciences is organising a lecture about the Galileo European navigation system Posted: 10 Apr 2011 08:17 PM PDT The Galileo European navigation system is made up of a constellation of 30 satellites that will guarantee presence of a minimum of four satellites at any one time (the number necessary to determine position) anywhere around the Earth. In order to know some of the most relevant aspects of this European system the City of Arts and Sciences is organising today Tuesday 12 a lecture by Javier Ventura, European Space Agency (ESA) Communication Director. In the talk, which is part of the programme -Astronomy at the City of Arts and Sciences- and will be hosting the Science Museum Auditorium at 20.00 hours, this expert will talk about how Galileo, which has been developed by the European Union and ESA, has changed in recent years the navigation system market led so far by the United States or Russia, with GPS and GLONASS, respectively. After this talk, a free initiative with enrolment beforehand, the observation of the Moon by telescope will begin from the Umbracle, weather permitting. The activity will be coordinated by Jordi Cornelles (Valencian Astronomy Association) and will allow participants to observe the crescent of the 9-day old Moon and some of some of its curiosities as the Copernicus lunar crater, with 93 kilometre diameter, one of the brightest on the Moon. The City of Arts and Sciences seventh Astronomy series are focusing on the adventure of space exploration and has the collaboration of the British Council, French Institute in Valencia, Valencian Astronomy Association, Embassy of the United States and ESA. 50 years of first crewed spaceflight Today the Principe Felipe Science Museum wants also to commemorate the 50 anniversary of the first spaceflight by Russian cosmonaut Yuri Gagarin. Although in 1957 began the space race by launching Sputnik artificial satellite (USSR), it was not until 1961, specifically on April 12, when took place the first crewed spaceflight. After spending 108 minutes of flight aboard Vostok 1, Gagarin returned to Earth, becoming the first man to see the planet Earth from space. (PHOTO: ESA)
