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.

32017-05-29. GAO обнародовала данные о состоянии разработки КА Wide-Field Infrared Survey Telescope.
Согласно представленному отчету:
1. Целью миссии Wide-Field Infrared Survey Telescope (WFIRST) является широкозональная съемка и проведение исследования космоса в ближнем ИК диапазоне. Проект будет использовать телескоп, который ранее разрабатывался в интересах другого ведомства (не НАСА, более 10 лет назад). Также в рамках КА предполагается отработка технологий орбитального обслуживания спутника. Запуск КА планируется в середине 2020-х годов и он должен будет находиться на удалении около 1 млн. км. от Земли.
2. В феврале 2017 года космическое агентство США осуществило расчет предварительной стоимости проекта, который показал, что она будет составлять $3.2 – $3.8 млрд. (включая запуск). На сроки создания КА может оказать положительное влияние положительное решение об увеличении финансирования в 2018 году. Тэги: Wide Field Infrared Survey Telescope
42017-06-07. Northrop Grumman получила новый контракт.
Американский производитель аэрокосмической техники обнародовал данные о том, что он получил контракт от НАСА на предмет создания оптической системы коронографа, который будет установлен на космической обсерватории WFIRST. Ранее компания уже принимала участие в предварительной проработки концепции данной системы, которая проходила совместно с NASA Jet Propulsion Laboratory.
WFIRST – перспективная космическая обсерватория НАСА, проработка вопросов создания которой началась в 2010 году. Целью размещения коронографа на космическом аппарате назван поиск планет в других солнечных системах. Тэги: Wide Field Infrared Survey TelescopeКосмическое агентство СШАNorthrup Grumman
52017-06-24. Космическое агенство США начало независимую экспертизу миссии WFIRST.
НАСА объявило о том, что оно начало независимую проверку стоимости и сроков проведения миссии Wide Field Infrared Survey Telescope (WFIRST). В состав комиссии входят представители научного сообщества и технические специалисты. Предварительной датой запуска спутника названа середина 2020-х годов. К отличительным особенностям спутника возможно отнести то, что инфракрасный телескоп будет использовать 2.4 метровое зеркало, которое предоставило NRO. К основным проблемам процесса создания аппарата в агентстве отнесли существенное (около 11 процентов) снижение объемов государственного финансирования.
