Спутник ФКИ. Interface Region Imaging Spectrograph (IRIS). [Редактировать]

IRIS (Interface Region Imaging Spectrograph) — космический аппарат NASA для исследования Солнца. Миссия в рамках программы Small Explorer program (SMEX) по исследованию физических свойств солнечного лимба — видимого края диска Солнца, солнечной хромосферы. Построен аппарат для лаборатории Lockheed Martin Solar and Astrophysics Laboratory (LMSAL). На космическом аппарате установлен спектрометр, который создан лабораторией LMSAL, и телескоп Смитсоновской астрофизической обсерватории. Управлять аппаратом на орбите будут лаборатория LMSAL и Исследовательский центр Эймса NASA. Исследовательским инструментом аппарата является высокочастотный ультрафиолетный спектрометр, с частотой один кадр в секунду, с пространственным разрешением 0,3 угловой секунды, и со спектральным разрешением в долях ангстрема. NASA объявило 19 июня 2009 года, что проект IRIS был выбран для финансирования из шести кандидатур исследовательских миссий программы Small Explorer program (SMEX), наряду с проектом Gravity and Extreme Magnetism SMEX (GEMS). Космический корабль прибыл на военно-воздушную базу Ванденберг в штате Калифорния 16 апреля 2013 и был успешно запущен 27 июня 2013 года ракетой «Пегас XL».

12016-09-20. Космическое агентство США расширило контракт с Lockheed Martin на $19 млн.
НАСА расширила участие компании Lockheed Martin в проекте IRIS и теперь компания будет заниматься этим проектом до конца 2018 года (с возможностью продления работ до 2019). К настоящему времени обсерватория сделала более 24 миллионов снимков и спектральных измерений Солнца. По результатам наблюдений опубликовано более 115 статей.Тэги: Lockheed MartinКосмическое агентство СШАInterface Region Imaging Spectrograph (IRIS)
