12016-01-07. НАСА начало работу над своим следующим аппаратом.
Благодаря увеличению финансирования НАСА приступило к проработке своего следующего космического телескопа который должен быть запущен после JWST. Согласно заявлению директора астрофизического подразделения агентства новый аппарат получит наименование Wide Field Infrared Survey Telescope (WFIRST) и в 2016 году проект по его созданию пройдет стадию формулировки требований. В целом в НАСА отдельно отметили, что прогресс в данном направлении стал возможным только благодаря тому, что в бюджете на 2016 на развитие данного направления было выделено порядка 90 млн. долл. (запрашивалось 14 млн. долл.). Данное увеличение не является для проекта первым поскольку ранее конгресс выделял 50 млн. долл. в 2015 и 56 млн. долл. в 2014 годах. Относительно технических особенностей аппарата можно отметить то обстоятельство что он будет использовать одно из 2.4 метровых зеркал которые были переданы агентству NRO в 2012 году. Срок запуска нового аппарата определен 2024 годом.Тэги: Wide Field Infrared Survey TelescopeКосмическое агентство СШАJames Webb Space Telescope
22016-08-16. Стоимость новой обсерватории НАСА WFIRST может вырасти.
Прогнозируемая стоимость космической обсерватории НАСА Wide Field Infrared Survey Telescope (WFIRST) выросла на 25 процентов, согласно представленному агентством отчету. Первоначально в агентстве оценили разработку изделия в диапазоне от 2 до 2.3 млрд. долл., однако уже на первом этапе, когда проводится предварительная проработка проектного облика, стоимость космического аппарата выросла на 550 млн. долл. Как сообщается новое изделие должно будет быть запущено в точку Лагранжа L2 при помощи РН Дельта 4 тяжелая. Причиной увеличения потребного объема финансирования в НАСА назвали изменение технических требований к спутнику.
