 Скрытый текст:

The crew performed the steps necessary to reconfigure the CIR/ACME hardware components from the completed s-Flame part 2 experiment to BRE part 2 (Burning Rate Emulator), which is one of the ACME suite of five experiments. Although the crew was not able to locate and install igniter arm 2, the currently-installed igniter arm 1 was left in the system and will be assessed for acceptable alignment and function with the burner head during checkout. The BRE experiment runs are focused on spacecraft fire prevention. More specifically, BRE's objective is to improve our fundamental understanding of materials flammability and to assess the relevance of existing flammability test methods for low and partial-gravity environments.

Food Physiology:

 Скрытый текст:

The crew participated in a Food Physiology diet briefing with the ground team. The Integrated Impact of Diet on Human Immune Response, the Gut Microbiota, and Nutritional Status During Adaptation to Spaceflight (Food Physiology) experiment is designed to characterize the key effects of an enhanced spaceflight diet on immune function, the gut microbiome, and nutritional status indicators. These factors are interlinked, but diet is the only one that can be easily and meaningfully altered on Earth or during flight. This investigation aims to document the effect of dietary improvements on human physiology and the ability of those improvements to enhance adaptation to spaceflight.

Environmental Health System (EHS) Total Organic Carbon Analyzer (TOCA) Water Recovery System (WRS) Sample Analysis & Data Record:

 Скрытый текст:

The crew performed an analysis of the water processing assembly (WPA) using the TOCA.

MSRR/MSL (Materials Science Laboratory) SCA exchange:

 Скрытый текст:

The crew removed the processed calibration cartridge and inserted the first ESA batch-2b Sample Cartridge Assembly (SCA). Batch-2b serves two projects investigating how different phases organize in a structure when metallic alloys are solidified. The project Metastable Solidification of Composites (METCOMP) studies the phase formed by the reaction of the remaining liquid phase with an already formed solid, to form a second solid phase on cooling. For this purpose, Bronze (Copper-Tin Alloys) of different compositions will be processed. The other project, Solidification along a Eutectic path in Ternary Alloys (SETA), looks at how two phases that form together organize into lamellar, or fiber, structures when cooling Aluminum (Copper-Silver Alloys). Both projects will provide benchmark samples that will enable to test numerical models that aim to predict these structures.

Posted Aug 31, 2020 at 12:09 pm


Sunrise casts long shadows over a cloudy Philippine Sea as the International Space Station orbited off the coast of the Philippines.

The Expedition 63 crew kicked off the work week exploring space agriculture and spacecraft technologies. The trio also split the day on upcoming mission preparations and International Space Station maintenance.

Ongoing botany studies on the station have been teaching scientists, engineers and astronauts how to grow crops in space, so crews can feed themselves farther away from Earth. Future astronauts on long-term missions to the Moon, Mars and beyond will need to be self-sufficient with less support from mission controllers and resupply missions.

Commander Chris Cassidy set up the Advanced Plant Habitat during the afternoon for upcoming grow operations in the research facility. The controlled plant growth chamber automates the delivery of nutrients and light to support a variety edible plants for harvesting, analysis and tasting.

Cassidy is also gearing up for a U.S. resupply mission due to replenish the orbiting lab in early October. The NASA astronaut is sharpening his robotics skills on a computer to get ready to capture Northrop Grumman's Cygnus cargo craft with the Canadarm2 robotic arm.

A Russian technology experiment is using acoustics to locate micrometeoroid impacts on the space station. The two flight engineers, Anatoly Ivanishin and Ivan Vagner, partnered during the morning checking hardware and downloading data that may pinpoint the location of high-speed particle hits on the outside of the space lab.

The cosmonaut duo then spent the rest of Monday servicing life support gear and updating computer systems.

Busy Day of Science Rack Swaps and Life Support Work

Mark Garcia
Posted Sep 1, 2020 at 4:33 pm


A waxing gibbous moon is pictured above the Earth's horizon as the station orbited above the Atlantic Ocean off the coast of Brazil.

It was a busy Tuesday aboard the International Space Station as the Expedition 63 crew reorganized science racks and serviced life support hardware.

Since its inception, the main focus of the orbiting lab has been research that is only possible in microgravity. Scientists take advantage of these unique insights to improve health and industry for humans on Earth and in space. A variety of specialized racks throughout the station's laboratory modules host numerous science experiments revealing phenomena only seen in weightlessness.

Commander Chris Cassidy and Flight Engineer Ivan Vagner partnered up today, moving three dedicated science racks, also known as EXPRESS racks, and installing them inside the U.S. Destiny, Japan's Kibo and Europe's Columbus lab modules.

A total of 11 refrigerator-sized EXPRESS racks are installed on the station supporting a multitude of experiments. The internationally sponsored studies are tended to by astronauts, remotely controlled by scientists on Earth, as well as programmed to run automatically.

Veteran cosmonaut Anatoly Ivanishin concentrated on life support maintenance tasks in the Russian segment of the space station. He replaced dust filters in the ventilation system in his side of the orbital lab before servicing an oxygen generator and a carbon dioxide filter.

Российский сегмент МКС пока не готов к автономной работе - Роскосмос
02.09.2020 12:00:17

Москва. 2 сентября. ИНТЕРФАКС - Для перехода на полностью автономную работу российскому сегменту МКС понадобится еще несколько модулей, заявил исполнительный директор "Роскосмоса" по пилотируемым программам Сергей Крикалев.

"Да, наверное, смогут, но присоединение других модулей с определенным функционалом все-таки потребуется. Все будет зависеть от конкретных условий", - сказал Крикалев в интервью официальному изданию "Роскосмоса" "Русский Космос", отвечая на вопрос, сможет ли российский сегмент МКС использоваться автономно.

По его словам, в "Роскосмосе" могут рассмотреть вопрос об отделении российского сегмента от американского, "если по каким-либо причинам будет принято решение о прекращении работы станции, а у нас останутся модули, продолжение эксплуатации которых будет целесообразно".

"Сейчас становится понятным: вложив так много труда в создание российского сегмента МКС, получив опыт эксплуатации этой станции, просто взять и прекратить работу - мягко говоря, нецелесообразно. Поэтому мое личное мнение: в ближайшие 10 лет МКС продолжит свое существование в том или ином виде", - добавил Крикалев.

 Скрытый текст:

В середине мая глава "Роскосмоса" Дмитрий Рогозин сообщил, что Ракетно-космическая корпорация "Энергия" под руководством Игоря Озара, занявшего должность исполняющего обязанности гендиректора, займется разработкой концепции новой орбитальной станции.

Позднее Рогозин сообщил о планах создания собственной космической станции после 2030 года. По его словам, на станции будут осуществляться дозаправка спутников и сборка аппаратов для освоения дальнего космоса.

В станции планируется использовать часть новых российских модулей, разрабатываемых для МКС, в том числе узловой и энергетический.

В декабре 2019 Рогозин сообщил, что Россия может отказаться от запуска узлового и научно-энергетического модуля ради создания лунной станции. "Мы должны взвесить, есть ли смысл отправлять последующие модули на МКС, если жизнь МКС уже понятна, это 2028 год, а у этих модулей будет ресурс 15-20 лет. Стоит ли их отправлять на три-четыре года, чтобы потом топить в океане вместе со станцией? Я не уверен", - отметил глава "Роскосмоса".

Скончавшийся в мае от коронавируса генконструктор "Энергии" Евгений Микрин ранее называл целесообразным после завершения проекта МКС создание российской орбитальной станции, не исключив при этом международное участие в проекте.

"На эту станцию можно будет перенести все дорогостоящее оборудование с российского сегмента МКС. Она будет состоять из пяти модулей. Первые три - МЛМ, узловой и НЭМ с МКС - плюс ещё два новых. Она будет иметь массу 60 тонн", - заявлял Микрин.

В данный момент Россия планирует запустить к МКС три новых модуля - "Наука" узловой и научно-энергетический. Как сообщал в интервью "Интерфаксу" гендиректор компании "Главкосмос" Дмитрий Лоскутов, дооснащение российского сегмента МКС данными модулями позволит в течение трех лет сделать его независимым.

Expedition 63 Commander Chris Cassidy of NASA and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner spent a full day after the holiday weekend on investigations that will help demystify the effects of space on the human body, as well as some routine maintenance tasks to ensure the health of the International Space Station -- now in its 20th year supporting crews in space.

In the JAXA (Japan Aerospace Exploration Agency) Kibo laboratory module, Cassidy spent the first part of his Tuesday with Aquatic Habitat, a unique closed-water circulatory aquarium capable of accommodating small freshwater fish such as medaka or zebrafish, which serve as ideal subjects in the study of vertebrates. The station commander performed lens collection for the Confocal Space Microscopy setup and closeout, helping to maintain the microscope capable of providing fluorescence images of biological samples that inform scientists on the ground about the fundamental nature of cellular and tissue structure and functions. Cassidy later used the Biomolecule Sequencer for Genes in Space 6, which evaluates how exposure to radiation affects the long-term health of astronauts. The investigation, part of a series, will aid in finding the optimal DNA repair mechanisms that cells use in microgravity.

Meanwhile, on the Russian segment, Ivanishin furthered understanding in how the heart performs during long-duration spaceflight by setting up, and then wearing, an electrocardiogram for a 24-hour period. The crew member also wiped down instrumentation during routine maintenance and configured Earth-observation hardware to capture changes in the planet below.

Vagner, too, did some housekeeping for the outpost, performing transfers to Progress 75 cargo ship tanks in anticipation of its deorbit in Earth's atmosphere sometime in December. The cosmonaut also focused on the Pilot-T piloting spacecraft and robots study, which uses a mathematical assessment model to develop recommendations and improve the training for cosmonauts expected to perform complicated operator tasks such as docking or flying spacecraft.

ISS Daily Summary Report - 9/08/2020

Confocal Space Microscopy:

 Скрытый текст:

The crew removed optical lenses from the Confocal Space Microscope hardware. The Payload Control Box Hard Drive was also reconfigured for the Confocal Space Microscope. The Confocal Space Microscope (Confocal Microscope) is a JAXA facility that provides fluorescence images of biological samples aboard the International Space Station. Confocal microscopy uses spatial filtering techniques to eliminate out-of-focus light or glare in specimens whose thickness exceeds the immediate plane of focus. With the Confocal Microscope, data can be obtained on the fundamental nature of cellular and tissue structure and functions in real-time.

STP-H5-Innovative Coatings Experiment (ICE):

 Скрытый текст:

On GMT 251, the crew took photographic images of the STP-H5 ICE experiment through the JEM window as part of a quarterly imagery requirement. The harsh radiation and extreme temperatures of space can corrode the paint and coatings that protect spacecraft exteriors, potentially damaging a spacecraft's hull. Optical coatings are also important for robotic and human navigators, who would rely on specialized markings to capture or repair spacecraft. The Space Test Program-H5-Innovative Coatings Experiment (STP-H5 ICE) studies new coatings for use on spacecraft in low-Earth orbit, determining their stability after two years in space.

Genes in Space-6:

 Скрытый текст:

The crew performed the setup of the Biomolecule Sequencer with a new Flow Cell sample and initiated a sequencing run. Deoxyribonucleic acid (DNA) damage caused by increased exposure to radiation can affect the long-term health of astronauts. Genes in Space-6 determines the optimal DNA repair mechanisms that cells use in the spaceflight environment. The investigation evaluates the entire process in space for the first time by inducing DNA damage in cells and assessing mutation and repair at the molecular level using the miniPCR and the Biomolecule Sequencer tools aboard the space station.

Regenerative Environmental Control and Life Support System (ECLSS) Recycle Tank Drain/Fill:

 Скрытый текст:

Today, the crew set up the recycle tank to drain to a ЕДВ-У. Following the setup the ground performed the tank drain using the Urine Transfer System (UTS). Once the ground specialists completed the transfer, the crew verified the recycle tank was empty, terminated the drain, and repositioned the fill/drain valve to fill.
