На новый марсоход NASA «Марс-2020» установили колеса

Инженеры аэрокосмического агентства NASA завершили монтаж подвески и установку шести колес на новом марсоходе «Марс-2020», который планируется высадить в марсианском кратере Джезеро диаметром 45 километров в феврале 2021 года, сообщает Лаборатория реактивного движения (JPL) в Пасадине, где ведутся все работы по сборке аппарата.

Особенность подвески марсохода «Марс-2020»

Как сообщает источник, каждое колесо диаметром 52,5 сантиметра изготовлено из алюминия и оснащено 48 грунтозацепами для увеличения проходимости машины по не самому удобному для передвижения грунту Марса. Штанги и рычаги подвесной системы для большей прочности выполнены из титана. Каждое колесо снабжено мотором. В дополнении к этому передняя и задняя пары снабжены рулевой системой для того, чтобы «Марс-2020» мог совершать оборот на 360 градусов, не сдвигаясь с места.

«Вот теперь это настоящий марсоход. Он с подвесной системой не только выглядит как настоящий марсоход, но и готов для интеграции с важнейшими составляющими, если смотреть в зеркало заднего вида», — прокомментировал один из руководителей программы создания «Марс-2020» в Дэвид Грюел из Лаборатории реактивного движения.

Дополнительно сообщается, что сама подвеска качельного типа аналогична той, что используется на марсоходе «Кьюриосити», который в настоящий момент трудится на поверхности Красной планеты. Благодаря этому новый марсоход рассчитан на движение по поверхности с наклоном до 45 градусов и развивать ошеломительную скорость в 152 метра в час. Однако отмечается, что специалисты NASA будут подбирать маршрут таким образом, чтобы показатель наклона поверхности не превышал 30 градусов.

В ближайшие недели специалисты NASA собираются заняться установкой механической руки-манипулятора, мачты с камерой и системы забора образцов грунта.

Без учета руки-манипулятора длина марсохода составляет около 3 метров, ширина – 2,7 метра, а высота – 2,2 метра. Масса полностью снаряженного аппарата составит 1050 кг, но в условиях марсианской гравитации его вес будет казаться меньше.

Для запуска новой автономной марсианской научной лаборатории в июле 2020 года с мыса Канаверал планируется использовать ракету-носитель «Атлас-5». Одна из главных задач марсохода будет заключаться в поиске следов жизни на Марсе, а также исследовании геологических особенностей строения Красной планеты и состава марсианской атмосферы.

Напомним, что вместе с новым марсоходм на Красную планету отправится компактный вертолет. Ученые из NASA хотят проверить, можно ли летать в условиях разряженной марсианской атмосферы. Почитать подробнее об этой затее можно в одном из наших предыдущих материалов.
