Спутник ФКИ. Gaia. [Редактировать]

GAIA (Global Astrometric Interferometer for Astrophysics) – космический телескоп, предназначенный для высокоточных измерений координат и движения звезд нашей Галактики с последующим созданием нового фундаментального звездного каталога и трехмерной карты нашей звездной системы. Предполагается, что помимо этого он сможет открыть около 10 тыс. экзопланет, а также астероиды и кометы в Солнечной системе. Телескоп будет выведен в точку Лагранжа L2, планируемый срок работы аппарата – пять лет.

12014-01-10. Представители Европейского космического агентства сообщили, что 8 января космический телескоп GAIA достиг точки либрации L2. В ближайшие три месяца будет продолжаться проверка установленного на борту космического аппарата оборудования, после чего он начнет свою работу по созданию самой точной и объемной карты звезд нашей галактики.Тэги: Gaia
22014-01-17. 15 января в 19:30 по московскому времени космический телескоп Gaia (гайа) на короткое время включил двигатели для того, чтобы завершить выход на запланированную научную орбиту вокруг точки L2 на расстоянии 1,5 млн километров от Земли. Интересно, что при этом на самом деле точка L2 – это ничто, просто точка в космосе. "Точки Лагранжа – особенные. Там, действительно, ничего нет. Это - точки в системе из двух массивных тел, например, Земли и Солнца, в которых третье тело, масса которого ничтожно мала по сравнению с этими телами, может оставаться относительно неподвижным. Эти точки дают нам уникальные возможности для проведения наблюдений за Солнцем или нашей галактикой", - говорит Маркус Ланграф (Markus Landgraf), аналитик миссии в операционном центре ESA в Дармштадте, Германия. Если смотреть из этой точки Лагранжа (всего в системе Солнце-Земля их пять), Солнце, Земля и Луна всегда будут близко расположены в небе, поэтому Gaia может использовать свой солнечный экран для того, чтобы уберечь свои приборы от воздействия света и жара, которые идут от этих трех тел одновременно. L2 дает умеренное радиационное излучение, которое поможет продлить срок действия жизни датчиков спутника в космосе. Однако, орбиты вокруг L2 изначально нестабильны. "Мы должны будем каждый месяц проводить маневры для того, чтобы Gaia оставалась на орбите L2, иначе она может «сойти» с нужной точки", - говорит технический руководитель проекта Дейвид Миллиган (David Milligan). Чтобы Gaia могла удержаться на этой орбите в течение пяти лет (срок миссии согласно планам), команда динамики полета миссии (эксперты, которые определяют траектории, подготавливают маневры на орбите и определяют позиции спутника) должна будет работать очень тщательно.
