The mission \u2013 launched in 2006 from the 17B launch base at the Cape Canaveral Air Force Station in Florida \u2013 consists of two twin probes \u2013 Solar A and Solar B \u2013 which observe the Sun from two very distant probes, obtaining stereoscopic images of our star and its phenomena, such as the coronal mass ejections and the solar wind. Both probes were launched to orbit around the Sun, practically at the same distance between Earth and the Sun, and were placed respectively in front and behind our star. During their journey, they tracked and are still tracking the flow of energy and matter from the Sun to our planet.<\/span><\/p>\r\n&nbsp;\r\n<p class=\"p1\"><strong><span class=\"s1\">Scientific goals<\/span><\/strong><\/p>\r\n<p class=\"p1\"><span class=\"s1\">The STEREO mission aims at investigating the origin, evolution and structure of coronal mass ejections, by taking stereoscopic pictures of the Sun. Thanks to the images released by STEREO, scientists are studying the structure of coronal mass ejections, violent eruptions of material from the Sun\u2019s corona that can lead to power outages and severe magnetic storms when they collide with Earth\u2019s magnetic sphere. <\/span><\/p>\r\n<p class=\"p1\"><span class=\"s1\">The big geomagnetic storms directed towards Earth can damage, and even destroy, satellites and are extremely dangerous for astronauts when they carry out extra-vehicular activities (EVA) and, therefore, are outside the shield of the Space Shuttle and the International Space Station.<\/span><\/p>\r\n<p class=\"p1\"><span class=\"s1\">Furthermore, STEREO provides images and data which are useful to study the evolution of the solar wind, which is important to understand more in depth the nature of the Sun, from the nucleus to the limits of the heliosphere, and the influence it has on the whole Solar System. <\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>Subject line: study of the Sun and its phenomena Responsibility of the mission: NASA Date of launch: October 26th, 2006 End of mission: ongoing &nbsp; Description STEREO (Solar Reports Observatory [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":2583,"parent":16481,"menu_order":536,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","footnotes":""},"categories":[],"tags":[],"class_list":["post-16517","page","type-page","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v25.9 (Yoast SEO v25.9) -
