Arecibo Observatory will be demolished

      Arecibo’s days are done. After two support cables failed in recent months, the radio observatory’s 305-meter-wide dish is damaged beyond repair, the National Science Foundation announced on November 19. It will be decommissioned and dismantled.

     The telescope, famous for appearances in movies like GoldenEye and Contact, consists of a wide dish to collect radio waves from space and focus them into detectors housed in a dome suspended above the dish.

     In August, one of the cables that holds up the dome slipped out of a socket and punched a hole in the dish. Then a second cable unexpectedly broke on November 6. If a third cable were to break, it could send the platform holding up the dome swinging, or the whole structure could collapse. 

     The NSF determined that there was no safe way to repair the telescope.

    Os dias de Arecibo acabaram. Depois que dois cabos de suporte falharam nos últimos meses, a antena de 305 metros de largura do observatório de rádio está danificada além do reparo, anunciou a National Science Foundation em 19 de novembro. Ela será desativada e desmontada.

    Se meu comentário estiver equivocado, por favor me avise por mensagem para que eu o corrija e evite assim prejudicar os demais colegas.

  • A resposta pode ser encontrada no terceiro parágrafo: "In August, one of the cables that holds up the dome slipped out of a socket and punched a hole in the dish. Then a second cable unexpectedly broke on November 6. "

    Alternativa D: Dois cabos se romperam e comprometeram a estrutura do telescópio.
