NASA изучит нетронутые образцы лунного грунта, собранные в рамках последних миссий «Аполлон»

Прошло уже почти полвека с момента последней высадки человека на поверхность Луны в рамках программы «Аполлон», однако большая часть образцов лунного грунта, собранных в ходе этой миссии, все это время находились в нетронутом состоянии. Сейчас аэрокосмическое агентство NASA готовится изучить ряд нетронутых образцов при помощи современных научных инструментов. Агентство считает, что для этого наконец-то пришло время – уровень технологий достиг таких высот, что позволяет получить ценные сведения о составе естественного спутника Земли, о которых узнать раньше было просто невозможно.

Среди образцов, которые готовится изучить NASA, присутствует грунт из Долины Тавр-Тавр-Литтров. Образец весит около 800 граммов и включает материал не только с верхних, но и с более глубоких слоев поверхности Луны, который собрали с помощью специальной трубки астронавты Харрисон Шмитт и Юджин Сернан в ходе миссии «Аполлон-17». Этот лунный грунт до сих пор не подвергался воздействию земной атмосферы и все это время хранился в герметически закрытых контейнерах в Центре космических полетов им. Джонсона в Хьюстоне (штат Техас).

Как сообщает New Atlas, в рамках программы The Apollo Next Generation Sample Analysis (ANGSA) аэрокосмическое агентство NASA отобрало девять исследовательских команд из различных организаций (в том числе из Центра космических полётов Годдарда NASA), которым будет предоставлено право изучить и провести анализ нетронутых образцов лунного грунта.

По мнению доктора Чарльза Ширара из Института метеоритики при Университете Нью-Мексико, руководителя одной из групп, которая наравне с другими пятью коллективами ученых займется изучением вышеназванного образца, NASA выбрало самое удачное время для этого исследования.

«Цель сохранения лунных образцов все это время заключалась в желании предоставить возможность новым поколениям ученых провести анализ нетронутого земной атмосферой лунного грунта. 50 лет назад у нас не было таких совершенных технологий анализа, которые мы имеем сейчас. Кроме того, современное представление о Луне несколько отличается от того, что думали люди о спутнике нашей планеты полвека назад. В 2020-х годах NASA с партнерами хочет вернуть людей на Луну. И то, как будет проходить это возвращение, а также то, чем конкретно будут заниматься люди на Луне, будет зависеть в том числе и от того, какие результаты покажет этот современный анализ лунного грунта», — объясняет специалист.

Что же современный анализ лунных образцов сможет рассказать нам такого, что не смог бы рассказать анализ тех же образцов, если бы он проводился в 70-х годах? Исследователи планируют использовать самое разное научное оборудование, которое позволит им установить в образцах точную концентрацию воды, газов и других летучих веществ. Полученные данные сравнят с результатами самых первых исследований лунного грунта, а также с данными, собранными окололунными орбитальными аппаратами в рамках более современных миссий к спутнику.

«За последние 50 лет появилось множество технологий, которые позволяют совершенно по-новому взглянуть на эти образцы. В основном, конечно же, речь идет о существенном повышении точности и масштабов исследований, а также развитии систем изотопного анализа. Например, различные инструменты и методы для электронной и ионной микроскопии, в частности, просвечивающая электронная микроскопия, метод фокусируемых ионных лучей и вторичная ионная масс-спектрометрия, позволяют проводить наблюдения и анализ на ангстремном уровне. Эти инструменты позволяют нам изучать и проводить исследование тонких оболочек летучих веществ, находящихся на поверхности минеральных частиц», — добавляет Ширар.

Специалист отмечает, что особенно полезными современные методы исследований и анализа могут быть для детального изучения лунных оползневых отложений. В частности, они могут позволить с большей точностью определить возраст оползней.

«Повышенная точность измерений позволяет нам более точно установить возраст важных геологических событий на лунной поверхности. В случае с образцами, которые были получены в ходе миссии «Аполлон-17», мы сможем точнее определить возраст оползневых отложений, а также больше разузнать о том, что явилось их причиной», — поясняет Ширар.

Другие группы, выбранные NASA в рамках ANGSA, также займутся изучением образцов, собранных в ходе миссии «Аполлон-17», а также образцов, собранных миссией «Аполлон-15».

«Первому поколению ученых и инженеров времен программы «Аполлон» уже за восемьдесят. Наша команда из Университета Нью-Мексико состоит из людей, относящихся к разным поколениям: начиная от ученых, которые изучали некоторые образцы лунного грунта еще в начале 70-х и заканчивая студентами и аспирантами. Эта работа станет отличной возможностью передать знания и опыт от первого поколения лунных исследователей будущим поколениям», — подытоживает Ширар.

    One more thing. It’s my opinion that there are many travel insurance web sites of reputable companies that allow you to enter your journey details and find you the quotations. You can also purchase the actual international travel cover policy on internet by using your own credit card. All you have to do should be to enter your current travel information and you can understand the plans side-by-side. Merely find the program that suits your finances and needs and after that use your credit card to buy the item. Travel insurance on the internet is a good way to do investigation for a reputable company with regard to international holiday insurance. Thanks for giving your ideas.
