12017-06-30. JAXA объявила о проведении очередного этапа тестирования.
Космическое агентство США объявило о проведении успешного тестирования ДУ LE-5B-3, которая должна быть установлена на вторую ступень РН Н3. По своим техническим характеристикам LE-5B-3 является дальнейшим развитием LE-5B-2, которая используется в составе второй ступени РН H-IIA/B. Основной целью модернизации является существенное уменьшение стоимости ракетного двигателя.Тэги: LE-5B-3Космическое агентство СШАСерия РН H3Серия РН H2
