Спутник ФКИ. Gravity Recovery And Interior Laboratory-B (GRAIL). [Редактировать]

Зонд построены фирмой Lockheed-Martin по заказу JPL NASA. В основе конструкции лежит платформа LM-300. Полная масса каждого зонда 230 кг, сухая масса –201кг. Размер зонда - 1,09 м х 0,95 м х 0,76 м. Каждый зонд имеет две панели солнечных батарей площадью 1,88 квадратных метра каждая, способных генерировать не менее 1400 Вт в целом, и литий-ионный аккумулятор емкостью 30 Ач. Двигательная установка состоит из основного двигателя MR-106L на гидразине с тягой 22 Н и 8-ми малых гелиевых двигателей с тягой 0,9 Н для управления ориентацией.

Система управления базируется на компьютере RAD-750 с памятью 128 Мб (512 Мб для записанных программ).

В основе основного эксперимента по построению гравитационной карты Луны лежит измерение расстояния между аппаратами, которое будет меняться по мере того, как они проходят лунные гравитационные аномалии. Каждый из зондов имеет три приемо- передатчика S-диапазона для связи с Землей и синхронизации времени, два передатчика Х -диапазона для передачи научных данных, радиомаяк для передачи сигналов на Землю и измерения доплеровского сдвига, транспондер Ка-диапазона для измерения расстояния между двумя космическими аппаратами.

Как отметила научный руководитель миссии Мария Зубер (Maria Zuber), сегодняшние технологии позволяют определять расстояние между аппаратами с точностью до нескольких микрометров — «меньше диаметра красной кровяной клетки человека». На зондах установлены также миниатюрные камеры MoonKAM, способные выполнять до 30 кадров в секунду. На каждом спутнике будет находиться до пяти камер, предназначенных для широкой популяризации полученной информации и образовательных программ. Студенты младших курсов университетов под руководством наставников смогут работать с камерами на расстоянии с помощью оборудования, имеющегося в Калифорнийском университете, Сан-Диего.
