12016-08-05. Vector Space Systems выиграла конкурс компании Iceye.
Специализирующаяся на малых космических аппаратов, компания Vector Space Systems, подтвердила запуск 21 космического аппарата радиолокационного дистанционного зондирования Земли. В качестве средства выведения в компании планируют использовать свою ракету-носитель Vector Micro Satellite Launch Vehicle, а сроком запуска определен 2018 год. Заказчиком пусков выступает Финляндская Iceye, которая решила начиная с 2017 года развернуть свою орбитальную группировку малых аппаратов ДЗЗ. Тэги: Vector Space SystemsVector
22016-08-16. Компания Vector Space Systems продолжает тестирование своих ракетных блоков.
Разработчик легких ракет провел успешное тестирование своего прототипа P-20, который должен был в ходе испытаний имитировать 12 метровую ракету Vector-1. На этот раз прототип имел размерность около 6 метров в длину. Компания также подтвердила что первый пуск изделия она осуществит в 2018 году. Стоимость пуска объявлена в 1.5 млн. долл.

32016-09-09. Vector Space Systems получила контракт от НАСА.
Оператор пусковых услуг анонсировала заключение с НАСА контракт на продолжение работ по разработке улучшенного прототипа верхней ступени своей ракеты Vector-R. Данный контракт является продолжением работы, которую ранее компания проводила для DARPA с целью оснащения подобным ракетным блоком экспериментального космоплана XS-1. Первые тесты нового блока пройдут в четвертом квартале 2017 года. Согласно новому контракту, в рамках работы Vector Sapce Systems проведет окончательную сборку, интеграцию и проверку полномасштабной версии блока. К проекту также планируется привлечь такие организации как University of Alaska Fairbanks и Alaska Aerospace Corporation (AAC), что позволит Vector SpaceSystems получить доступ к наземной космической инфраструктуре расположенной на острове Кодиак.Тэги: Vector Space SystemsVectorDARPAКосмическое агентство США
42016-10-16. Vector Space Systems решила обосноваться в Аризоне.
Разработчик ракет сверх-легкого класса решил локализовать свое производство в Аризоне. В связи с этим компания объявила что ее перспективные ракеты Vector-R/H будут производиться именно здесь. При этом, территориально производство будет находиться на территории которую местные власти специально выделили для подобных предприятий, запретив на ней строительство жилья и не профильную деятельность.Тэги: Vector Space SystemsVector
52016-10-19. Vector Space Systems анонсировала $60 млн соглашение с York Space Systems.
Компания Vector Space Systems объявила о скором завершении подготовки соглашения с аэрокосмической компанией York Space Systems, которая специализируется на аппаратах малого и среднего размера.
Целью соглашения будет являться запуск шести космических аппаратов в период между 2019 по 2022 года.
Также по условиям будущего контракта заказчик получит опцион на право пуска 14 РН.
Данный заказ будет являться первым в ходе которого будет использоваться РН Vector-H, которая должна будет выводить на орбиту до 100 кг. Также в ходе пусков компании планируют провести испытания полностью электрической верхней ступеней, которая должна будет позволить выводить те-же 100 кг на орбиту с высотой до 1000 км.

62016-12-21. Компания Vector Space Systems провела испытания двигателя первой ступени.
Компания Vector Space Systems анонсировала успешное проведение испытание ДУ первой ступени своей РН Vector R. Испытание проходило в Калифорнии. При этом, в ходе испытаний компания провела также и испытания распечатанного на 3Д принтере инжектора (разработка и проведение испытаний финансировалось НАСА). Также компания обнародовала данные о будущем экономическом эффекте от своего сотрудничества с государством которое выражается в увеличении ВВП региона на 290 млн. долл. (в течении следующих пяти лет) и обеспечение работой порядка 200 человек.Тэги: VectorVector Space SystemsКосмическое агентство США
72017-05-04. Компания Vector Space Systems провела тестирование инженерной модели.
Согласно сообщению оператора пусковых услуг 3 мая компания провела успешное низковысотное испытание инженерной модели своей РН Vector-R. Запуск состоялся в среду с полигона в пустыне Мохаве (штат Калифорния). В ходе испытаний одноступенчатая модель достигла высоты полета около 1.5 км, а целью запуска являлась проверка качества изготовленных при помощи 3Д принтеров инжекторов двигательных установок и других частей двигательной установки. В компании также отметили, что в ближайшее время они проведут еще порядка восьми испытательных пусков с целью набора статистики. Тэги: Vector Space SystemsVector
82017-05-19. Vector Space объявило о желании расширить свои пусковые возможности с минимальными вложениями в наземную инфраструктуру.
Компания Vector Space Systems, которая известна тем, что разрабатывает РН сверхлегкого класса, объявила о желании не только коренным образом снизить стоимость пуска малых КА и повысить оперативность предоставления услуг, но и о готовности рассмотреть возможности запуска своей РН с любой удобной стартовой позиции (включая и морские баржы). В компании также отметили, что характеристики ее РН были рассчитаны на основе предположения о запуске с Мыса Канаверал, что делает потенциально возможным повышение энергоэффективности за счет переноса места пуска ближе к экватору.Тэги: Vector Space SystemsVector
