L'expérience Solid Fuel Ignition and Extinction (SoFIE) Growth and Extinction Limits (GEL) à bord de la Station spatiale internationale étudie la croissance et l'extinction des flammes dans le but d'améliorer la sécurité incendie dans l'espace. Cette image montre une séquence d'instantanés pris à environ 3 secondes d'intervalle. Des échantillons de gel de l'enquête reviennent sur Terre pour une analyse plus approfondie sur le vaisseau spatial SpaceX CRS-27 cargo Dragon. Crédit : NASA

It was launched in 1998 and has been continuously occupied by rotating crews of astronauts and cosmonauts from around the world since 2000. The ISS is a joint project of five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits the Earth at an altitude of approximately 400 kilometers (250 miles), and provides a unique platform for scientific research, technological development, and human space exploration." data-gt-translate-attributes="[{"attribute":"data-cmtooltip", "format":"html"}]"> Station spatiale internationale (ISS) pour la NASA.

Suite aux commandes des contrôleurs au sol de SpaceX à Hawthorne, en Californie, Dragon s'est désamarré à 11h05 du port avant du module Harmony de la station. Au moment du désamarrage, la station survolait l'océan Indien.

Dragon arrived at the space station on March 16 as SpaceX's 27th Commercial Resupply Services mission for 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. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals." data-gt-translate-attributes="[{"attribute":"data-cmtooltip", "format":"html"}]"> NASA, livrant plus de 6 000 livres d'enquêtes de recherche, de fournitures d'équipage et de matériel de station.
