Команда ITD. Предложения проектов, приборов и технологий для миссий исследования астероидов, Луны, планет Марса и Венеры. Мы занимаемся разработкой проекта связанного с добычей льда на Марсе. Не смотря на то что эта проблема глобальная, мы прилагаем усилия чтобы ее решить. Наши основные проблемы это отсутствие инвесторов, так называемая игра в "долгую", по причине того, что колонизация Марса произойдет не раньше чем через 40-50 лет, а так же эта тема достаточно новая, и человек не обладает большим количеством ресурсов и знаний в этой сфере.
