Segundo a For\u00e7a Espacial dos Estados Unidos, a espa\u00e7onave reentrou na atmosfera por volta das 5h30 da manh\u00e3 (no hor\u00e1rio de Bras\u00edlia). No entanto, h\u00e1 uma margem de erro de 11 horas para mais ou para menos na previs\u00e3o.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Apesar da queda, a estimativa \u00e9 de que boa parte do equipamento se desintegre antes de alcan\u00e7ar o solo terrestre. <strong>Pequenos fragmentos podem at\u00e9 resistir, por\u00e9m as chances de atingir algu\u00e9m s\u00e3o baixas<\/strong> \u2013 cerca de 1 em 2,1 mil, segundo a Nasa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Durante a trajet\u00f3ria de retorno, a estrutura do telesc\u00f3pio deve passar pela \u00c1frica, Austr\u00e1lia, \u00c1sia e Am\u00e9ricas Central e do Sul.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Miss\u00e3o fracassada de resgate do telesc\u00f3pio<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Antes de confirmar o fim da miss\u00e3o do Swift e sua reentrada na Terra, <strong>uma parceria da Nasa com uma empresa privada tentou resgatar o instrumento para melhorar sua \u00f3rbita e fazer com que ele continuasse funcionando<\/strong>. Por\u00e9m, o plano n\u00e3o deu certo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Em 3 de julho, a espa\u00e7onave LINK, da empresa norte-americana Katalyst Space Technologies, foi lan\u00e7ada para se encontrar com o Swift no espa\u00e7o. O objetivo era acoplar ao instrumento por meio de tr\u00eas bra\u00e7os rob\u00f3ticos e impulsion\u00e1-lo para uma \u00f3rbita mais alta.<br><br>No entanto, o ve\u00edculo de resgate teve problemas em seus sistemas de propuls\u00e3o e de orienta\u00e7\u00e3o, o que impediu o cumprimento da tarefa. O m\u00e1ximo que a LINK conseguiu foi se aproximar do telesc\u00f3pio e registr\u00e1-lo no espa\u00e7o. Dessa forma, o Swift, lan\u00e7ado pela Nasa em 2004, teve que encerrar <a href=\"https:\/\/www.metropoles.com\/ciencia\/principais-achados-do-james-webb\" target=\"_blank\" rel=\"noopener\">suas atividades<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O funcionamento do telesc\u00f3pio ficou comprometido porque sua \u00f3rbita o exp\u00f4s ao arrasto atmosf\u00e9rico, que o puxou de volta \u00e0 Terra. Como n\u00e3o possui propulsores, o Swift \u00e9 incapaz de reverter a atra\u00e7\u00e3o.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">O legado do telesc\u00f3pio<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No per\u00edodo em que investigou o espa\u00e7o, o telesc\u00f3pio coletou diversos dados cient\u00edficos \u2013 <strong>a Nasa estima que cerca de 7 mil artigos cient\u00edficos tenham utilizado informa\u00e7\u00f5es obtidas por ele.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O objetivo principal do instrumento era estudar as explos\u00f5es de raios gama (GRBs), consideradas as mais poderosas do cosmos. Por\u00e9m, o Swift foi al\u00e9m e observou explos\u00f5es de supernovas, asteroides, cometas e buracos negros, al\u00e9m de realizar um levantamento de todo o c\u00e9u em raios X.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Foto: Reprodu\u00e7\u00e3o\/Espa\u00e7o Katalyst | Fonte: Metr\u00f3poles<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tempo de leitura: 2 minutos O Observat\u00f3rio Neil Gehrels Swift, um telesc\u00f3pio espacial da Nasa,<\/p>\n","protected":false},"author":3,"featured_media":5701,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[39],"class_list":["post-5700","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-ultimas-noticias","tag-destaque"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
