Pendant des mois, Voyager ne renvoyait aucune donn\u00e9e exploitable vers la Terre, qu\u2019il s\u2019agisse de donn\u00e9es scientifiques ou techniques. La situation a r\u00e9ellement inqui\u00e9t\u00e9 les scientifiques, qui ont travaill\u00e9 d\u2019arrache-pied pour r\u00e9tablir les communications avec la mission.<\/p>\n<p>Le sauvetage de Voyager 1 \u00e9tait d\u2019autant plus complexe qu\u2019il faut du temps pour envoyer des commandes \u00e0 la sonde. Elle est si loin de la Terre, \u00e0 24 milliards de km, qu\u2019il faut environ une journ\u00e9e pour lui envoyer un message, et autant pour recevoir sa r\u00e9ponse. Malgr\u00e9 tout, en mai 2024, les scientifiques sont parvenus \u00e0 retrouver un fonctionnement normal pour 2 des instruments scientifiques de Voyager 1.

Toutefois, les scientifiques de la Nasa ont encore un peu de travail pour que ce bug soit vraiment de l\u2019histoire ancienne. \u00ab Voyager 1 a repris ses activit\u00e9s scientifiques, mais d\u2019autres travaux mineurs sont n\u00e9cessaires pour rem\u00e9dier aux cons\u00e9quences de ce probl\u00e8me \u00bb, compl\u00e8te la Nasa. Au programme, notamment : \u00ab resynchroniser le logiciel de chronom\u00e9trage des 3 ordinateurs de bord de la sonde afin qu\u2019ils puissent ex\u00e9cuter les commandes au bon moment \u00bb.<\/p>\n<p>Le bug a perturb\u00e9 la mission, mais il ne la compromet plus. Voyager 1 peut continuer son voyage dans l\u2019espace interstellaire.
