Le télescope spatial romain Nancy Grace est un observatoire de la NASA conçu pour étudier l'énergie noire, les exoplanètes et l'astrophysique infrarouge. Doté d'un miroir primaire de 2,4 mètres (de taille similaire à celui du télescope spatial Hubble), le télescope romain aura un champ de vision plus de 100 fois plus grand que celui de Hubble, lui permettant de capturer une image plus complète de l'univers et de plonger plus profondément dans son mystères.

NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond.

The Roman Space Telescope is designed to study a wide range of cosmic phenomena, including the expansion of the universe, the formation and evolution of galaxies, and the search for exoplanets. It will be equipped with a wide-field camera that will allow it to survey a large portion of the sky and study objects in the infrared part of the electromagnetic spectrum.

Après une construction détaillée de deux ans et un processus préparatoire de « cuisson », l’assemblage du vaisseau spatial est en cours, avec de futures installations prévues pour les composants de puissance.

L'équipe du télescope spatial Nancy Grace Roman de la NASA a commencé à intégrer et à tester le câblage électrique du vaisseau spatial, ou faisceau, qui permet aux différentes parties de l'observatoire de communiquer entre elles. De plus, le harnais fournit de l'énergie et aide l'ordinateur central à surveiller le fonctionnement de l'observatoire via un ensemble de capteurs. Cela rapproche la mission de l’étude de milliards d’objets cosmiques et de la résolution de mystères comme l’énergie noire après son lancement d’ici mai 2027.

"Tout comme le système nerveux transporte des signaux dans tout le corps humain, le harnais de Roman connecte ses composants, fournissant à la fois puissance et commandes à chaque boîtier et instrument électronique", a déclaré Deneen Ferro, responsable du développement du projet de harnais de Roman au Goddard Space Flight Center de la NASA à Greenbelt. , Maryland. "Sans harnais, il n'y a pas de vaisseau spatial."

Pesant environ 1 000 livres, le faisceau est composé d’environ 32 000 fils et 900 connecteurs. Si les câbles étaient disposés bout à bout, ils s’étendraient sur 45 milles. Dirigés vers le haut, ils atteindraient huit fois plus haut que le sommet du mont Everest.
