Ariane 6 rocket launches two new Galileo system satellites from Guiana."},"content":{"rendered":"<strong>Science Writing-<\/strong> An Ariane 6 rocket from the European Space Agency (ESA) has taken off from the spaceport in French Guiana with two new satellites on board that will join the Galileo constellation and provide greater robustness to the European navigation program, which serves more than half of the world's population.\n\nAt 5:01 (GMT), as scheduled, the rocket took off with the two satellites ('Sat 33' and 'Sat 34'), which thus began a journey that will take them, if all phases are successfully completed during the next few hours, to an orbit located about 23,000 kilometers from the Earth's surface.\n\n\n<h2 class=\"wp-block-heading\" id=\"h-la-constelacion-galileo\">The Galileo Constellation<\/h2>\n\n\nThe more than thirty satellites that make up the Galileo constellation allow the precise positioning of billions of users through their mobile phones, vehicles or other devices, although they are also key to air or maritime traffic, for thousands of critical infrastructures or for emergency and rescue services.\n\nToday's launch was the fourteenth launch of operational Galileo satellites (a test one was launched in 2005), a program that began in 2011, and today's launch took place for the first time aboard an Ariane 6 rocket, the new European launcher designed to ensure Europe's autonomous access to space and capable of competing with those developed by major space companies, as it can carry very heavy payloads, of up to 12 tons.\n\n\n<h2 class=\"wp-block-heading\" id=\"h-el-lanzamiento\">The Launch<\/h2>\n\n\nJust four minutes after takeoff, the launch surpassed two of the most critical phases, when the capsule where the two satellites are attached separated from the booster and two minutes after the fairing, and just a few seconds later one of the engines that will propel the spacecraft to their orbit was turned on, although they must still separate and follow their trajectory alone.\n\nAlmost five hours passed until the two satellites separated and reached the orbit in which they will operate for the next few years, in which they have been activated and where the first tests have been carried out to evaluate their performance and verify that none of their components has been damaged due to the harsh conditions of the launch.\n\nFollowing the successful separation of the satellites, the remains of the Ariane 6 rocket, which carried them to their position in space, have been moved to a stable 'graveyard' orbit, located at a great distance from the satellites that are operational and serving Earth.\n\nIn the coming days, more tests and calibrations of 'Sat 33' and 'Sat 34' will begin, which will last for several months, before the two join the constellation already formed in space by more than thirty satellites of the Galileo program.\n\n\n<h2 class=\"wp-block-heading\" id=\"h-uno-de-los-programas-mas-emblematicos-de-la-ue\">One of the most emblematic EU programs<\/h2>\n\n\nThe system, considered the most accurate in the world, is one of the EU's most emblematic programs and is funded by the European Commission, and since its creation at the beginning of the century, the European Space Agency has led its design, development, and qualification, in addition to contracting the launches that have taken place to date.\n\nThe Galileo program has a very direct impact on numerous daily activities of millions of citizens around the world, as it facilitates navigation in urban environments, is integrated into driving assistance systems, and has proven its usefulness in sectors such as agriculture, emergencies, or logistical operations, as well as in air and maritime navigation.\n\nAbout five hours after takeoff, and when the first tests that have reported the good health of the two satellites were completed, those responsible for the control center of the European spaceport in Kourou declared the success of the launch, which has been received with applause in the room and then began an event organized by the European Commission in Brussels, which has begun with a prolonged applause for those responsible for the mission.\n\n\n<h2 class=\"wp-block-heading\" id=\"h-espanoles-en-el-proyecto\">Spaniards in the project<\/h2>\n\n\nThe program has involved numerous Spanish companies in the aerospace sector, including GMV, which leads the development of the control segment that keeps the constellation operational 24 hours a day and has valued that today's launch represents a step forward for European technological autonomy and also comes at a \"key\" moment, as some of the first satellites are nearing the end of their useful life and the new ones will allow maintaining the same services offered by the Galileo program.\n\nToday's launch was also one of the last three launches of first-generation 'Galileo' satellites, after which the project will move on to second-generation spacecraft that will offer new capabilities, greater precision, and greater robustness against interference and cyber threats.\n\nSeveral representatives from ESA and the Ariane group who were present have spoken today during the launch broadcast - which lasted almost six hours - and have valued the milestone that it represents for the EU and the European Space Agency, as the new heavy-lift launcher guarantees Europe's strategic autonomy and access to space, as well as the importance and significance of the Galileo program in the current geopolitical context.","protected":false},"excerpt":{"rendered":"<p>Science Writing- An Ariane 6 rocket from the European Space Agency (ESA) has taken off from the spaceport in French Guiana
