Спутник ФКИ. Mars Express. [Редактировать]

Автоматическая межпланетная станция Европейского космического агентства, предназначенная для изучения Марса. Космический аппарат состоял из орбитальной станции — искусственного спутника Марса и спускаемого аппарата с автоматической марсианской станцией «Бигль-2». 

Измерения при помощи созданных российскими учёными совместно с западноевропейскими коллегами приборов позволили получить ряд важных научных результатов, многие из которых только готовятся к научным публикациям. В том числе восстановление структуры атмосферы с высокой точностью от поверхности до высот 100—150 км и её температурного профиля до 50—55 км. Впервые одновременно измерено содержание и построены карты распределения водяного пара и озона в атмосфере. Обнаружено ночное свечение моноксида азота, известного на Венере, но не наблюдавшегося ранее на Марсе. Открыты мельчайшие аэрозольные частицы, заполняющие атмосферу планеты до высот 70—100 км. Впервые обнаружен водяной лёд в южной полярной шапке в конце марсианского лета. Карты, построенные по данным прибора OMEGA с разрешением 1—3 км, показывают, что участки водяного льда находятся на краях более обширных областей замёрзшей углекислоты. Толщина её слоя не превышает нескольких метров, а под ним — захороненный слой водяного льда, возможно по мощности эквивалентный северной полярной шапке, полностью состоящей из водяного льда с небольшой (менее 1 %) примесью пыли. Прибором OMEGA проведено также минералогическое картирование значительной части планеты, и, при существенном разнообразии минерального состава, карбонаты (соли угольной кислоты) обнаружены не были. Они широко распространены на Земле и именно в их залежах, а не в живом веществе, каменном угле и нефти, сосредоточено основное количество углерода на нашей планете. Таким образом, данные «Mars Express» не подтверждают наличия запасов СО2 на Марсе, достаточных для существенных изменений массы его атмосферы, и соответственно, преобразования климата планеты. «Марс-экспресс» обнаружил в атмосфере Марса метан, что может свидетельствовать о наличии жизни на планете (метан не может долго находится в марсианской атмосфере, следовательно его запасы пополняются либо в результате жизнедеятельности микроорганизмов, либо вследствие геологической активности). Было определено и его содержание — 10±5 частей на миллиард. Конечно, это немного, но так как метан непрерывно разрушается в атмосфере за счёт фотодиссоциации, то для поддержания такого его количества в атмосфере на Марсе должен быть источник производительностью порядка 300 тонн метана в год. Таким источником могла бы быть тектоническая деятельность, Марс, считается тектонически неактивным в настоящее время, однако поступление метана в атмосферу может быть связано с «точечной» тектоникой: остаточным вулканизмом, либо геотермальной активностью. Благодаря снимкам косморобота учёные смогли сконструировать и представить трёхмерные модели марсианских ландшафтов. Станция обнаружила плотные облака из сухого льда, которые отбрасывают тень на поверхность планеты и даже влияют на её климат.

32014-12-17. Российские ученые из Института космических исследований ИКИ РАН и МФТИ совместно с французскими и американскими коллегами составили «карту» распределения водяного пара в атмосфере Марса и проследили за сезонными колебаниями его концентрации с помощью данных, собранных за десять лет российско-французским спектрометром SPICAM на борту зонда «Марс-Экспресс». Это самый длительный период наблюдений и самый большой объем данных об атмосферной воде на Марсе. Первоначально прибор SPICAM (Spectroscopy for Investigation of Characteristics of the Atmosphere of Mars) создавался для российского марсианского зонда «Марс-96». Новая существенно переработанная версия инструмента была создана при участии ИКИ в рамках соглашения между Роскосмосом и французским космическим агентством CNES по проекту марсианского зонда «Марс-Экспресс». Этот аппарат 2 июня 2003 года был запущен с космодрома Байконур с помощью российской ракеты-носителя «Союз» с разгонным блоком «Фрегат». В конце декабря 2003 года «Марс-Экспресс» вышел на околомарсианскую орбиту и с тех пор успешно работает, собирая данные о планете и ее окрестностях.Тэги: Mars ExpressИКИ РАНМФТИ
