12016-04-13. Компания Airbus заключила соглашение с CNES.
Французское космическое агентство и компания Airbus заключили контракт на производство оптического прибора для космического аппарата MicroCarb, который должен будет измерять содержание в атмосфере и источники CO2. Microcab будет являться первым европейским аппаратом который будет исключительно измерять и искать источники диоксида углерода. Основу прибора составит спектрометр который будет работать в видимом и инфракрасном диапазонах спектра.Тэги: Airbus GroupMicroCarbКосмическое агентство Франции
22017-03-10. Мари-Сеголен Руаяль открыла новое производство в Тулузе.
Мари-Сеголен Руаяль в ходе своего визита в Тулузский космический центр официально открыла здание Pierre Auger, которое является первым помещением CNES разработанное по требованиям HQE. В дальнейшем здание общей площадью в 5700 квадратных метров будет задействовано для проведения испытаний ракетно-космической техники на предмет поведения в условиях космоса. Также в процессе открытия министр объявила о том, что страна запустит КА MicroCarb в 2020 году. Аппарат будет позволять измерять концентрацию углекислого газа.Тэги: MicroCarbКосмическое агентство Франции
32017-04-19. CNES и космическое агентство Великобритании подписали соглашение.
Космические агентства Франции и Великобритании подписали соглашение о совместном участие в проекте по запуску космического аппарата MicroCarb. Целью проведения работ по созданию и запуску космического аппарата будет являться изучение вопросов связанных с круговоротом углекислого газа в природе. Запуск КА запланирован на 2020 год. Помимо предприятий промышленности в проекте также будут принимать участие университеты Эдинбурга и Лестера. Тэги: MicroCarbКосмическое агентство ФранцииКосмическое агентство Великобритании
