Micro-11:
Спойлер
Today the crew performed the final two sessions for the Micro-11 investigation. They checked out, configured and calibrated the Micro-11 microscope, thawed samples removed fr om a General Laboratory Active Cryogenic ISS Experiment Refrigerator (GLACIER), fixed those samples and loaded them into the microscope for imaging. Afterwards, they ins erted the samples into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). There are thirteen runs for the Micro-11 investigation. Micro-11 examines whether spaceflight alters human sperm, by tracking the swimming patterns of human and bull sperm during spaceflight. This investigation also assesses other aspects of sperm functionality related to male fertility. As a result, Micro-11 provides fundamental data indicating whether successful human reproduction beyond Earth is possible, and whether countermeasures are needed to protect sperm function in space.

AngieX Cancer Therapy:
Спойлер
The crew performed microscope and operations sessions for the AngieX Cancer Therapy investigation today. The AngieX Cancer Therapy investigation examines whether endothelial cells cultured in microgravity represent a valid in vitromodel to test effects of vascular-targeted agents on normal blood vessels. AngieX has developed a treatment that targets both tumor cells and vasculature, but needs a better model on which to test it. This study may facilitate development of a cost-effective method that does not require animal testing and which may help develop safer and more effective vascular-targeted drugs.

Aerosol Samplers:
Спойлер
Today the crew deployed Active Aerosol Samplers (AASs) in Nodes 2 and 3. The battery-powered AASs actively pull in air and collect particles using the principal of thermophoresis. This is accomplished by flowing the sampled air through a large thermal gradient in a narrow channel. During this process, particles are driven to the cold side of the channel, wh ere an electron microscope (EM) grid is held in place by a tiny magnet. When returned to Earth, these grids are easily removed and placed directly in an EM for analysis.

Спойлер
Today a crewmember retrieved Biophysics 4 Plate 2 from the Fluids Integrated Rack (FIR) at the end of its science run. They inspected it and then placed it inside a Microgravity Experiment Research Locker / INcubator (MERLIN). Proteins are important biological molecules that can be crystallized to provide better views of their structure, which helps scientists understand how they work. Proteins crystallized in microgravity are often higher in quality than those grown on Earth. LMM Biophysics 4 examines the movement of single protein molecules in microgravity.

Remote Power Controller Module (RPCM) N21A4A-C Remote Power Controller (RPC) 7 Trip:
Спойлер
On June 30, the RPC feeding the Node 2 Port Aft Intermodule Ventilation (IMV) Valve tripped with indications of a true overcurrent. Today, this RPCM was loaded with the firmware version 07P1 update that enables additional data collection at 1 kHz frequency. RPC 7 was closed, and remained closed for 77 minutes before tripping open again. Review of the trip signature indicates the trip today is due to Overcurrent. Per agreement at the July17 Ops tagup, RPC 7 will remain open (closed command inhibited) and the crew will manually close the IMV valve if required in an emergency. Ground teams will investigate the latest signature and the path forward.

Micro-12:
Спойлер
On Sunday, the crew activated all eighteen Micro-12 Group Activation Packs (GAPs) by mixing microbial media and inoculum. Then crew terminated one GAP by adding a microbial fixative to preserve the organism for subsequent ground-based characterization. Today the crew terminated additional GAPs. Micro-12 examines the effects of spaceflight on the physiology of an exoelectrogenic microorganism, Shewanella oneidensis MR-1. Exoelectrogenic microbes can pass electrons through their cell membranes, and so can be used in microbial fuel cells to make electricity fr om waste organic material. This investigation is expected to provide insight into how microgravity affects biological electron transport systems, and microbial fuel cell use in future space missions.

Space Algae:
Спойлер
On Sunday, the crew photographed the Space Algae culture bags in the Veggie facility and then removed and placed them in a stowage bag for return. They then shut down the Veggie facility. The Space Algae investigation explores the genetic basis for productivity of algae cultivated in space and whether this requires genetic adaptations or not. Algae may perceive microgravity as an abiotic stress, which can trigger production of high value compounds. Investigators plan whole genome sequencing of the space-grown algal populations to identify genes related to growth in spaceflight and testing of algal composition for production of high value compounds.

Today the crew removed one Chemical Gardens 2 ampoule kit from a Cargo Transfer Bag, broke the seal between the two ampoules in each sample bag and mixed the contents of both. In the Chemical Gardens experiment, sel ected metal salts are added to an aqueous solution of sodium silicate (Na2SiO3), resulting in the formation of inorganic structures that resemble plant growth in a time span ranging fr om minutes to hours. On Earth, gravity-induced flow due to buoyancy differences between the reactants complicates our understanding of the physics behind these "chemical gardens". Conducting this experiment in the microgravity environment onboard the ISS removes the gravity effects, ensures diffusion-controlled growth, and allows researchers a better assessment of initiation and evolution of chemical gardens.

Astronaut Alexander Gerst practices cardiopulmonary resuscitation (CPR) as cosmonaut Sergey Prokopev looks on during an emergency training session aboard the International Space Station.

The Expedition 56 crew has nearly completed loading the SpaceX Dragon resupply ship with cargo for retrieval back on Earth this Friday. The orbital residents are also busy with an intense day of space research and Russian spacewalk preparations.

Dragon is due to be released Friday at 12:37 p.m. EDT from the International Space Station carrying several tons of experiment results and orbital lab hardware. The crew has been packing the crucial research samples this week inside specialized, portable freezers onboard the commercial space freighter.
Спойлер
SpaceX technicians will pick up Dragon with its precious cargo after it splashes down in the Pacific Ocean and return to shore in southern California. Scientists and engineers will then begin the process of analyzing the critical space science and refurbishing station hardware.

Astronauts Serena Auñón-Chancellor and Alexander Gerst spent Wednesday morning helping doctors understand how living in space impacts the human eye. They are exploring the hypothesis that upward fluid shifts in the body caused by microgravity increases pressure on the brain possibly pushing against the eyes. This may affect the shape of the eye and permanently affect vision.

Cosmonauts Oleg Artemyev and Sergey Prokopyev are getting ready for a spacewalk on Aug. 15. The duo reviewed the translation paths to their work sites on the outside of the station's Russian segment. During the near seven-hour excursion, the spacewalkers will hand-deploy four tiny satellites, install antennas and cables on the Zvezda service module and collect exposed science experiments.

NASA Johnson

Опубликовано: 1 авг. 2018 г.

Trillions of microorganisms live on and in the human body, many of them essential to its function and health. These organisms, collectively known as the microbiota, outnumber cells in the body by at least five times.

Microorganisms in the intestinal tract, the gut microbiota, play an especially important role in human health. An investigation on the International Space Station, Rodent Research-7 (RR-7), examines how the gut microbiota changes in response to spaceflight, and how that change in turn affects the immune system, metabolic system, and circadian or daily rhythms.

ЦитироватьВ NASA оценили расходы на вывод МКС с орбиты
10:25 02.08.2018 (обновлено: 11:19 02.08.2018)

МОСКВА, 2 авг — РИА Новости. Сведение Международной космической станции (МКС) с орбиты потребует 950 миллионов долларов и двух лет работ, говорится в отчете офиса генерального инспектора NASA, опубликованном на сайте агентства.
Спойлер
Сборка МКС началась в 1998 году. Первоначально планировалось, что станция прекратит работу в 2020 году, но ее эксплуатацию продлили до 2024 года. Сейчас обсуждается возможность продления работы еще на четыре года. Основными партнерами по МКС выступают Россия, США, Европа, Япония и Канада.

В отчете описывается, что перед сведением станции с орбиты экипаж должен будет покинуть ее, а сама операция будет проводиться в автоматическом режиме российским Центром управления полетами.

По оценкам NASA, около 16 процентов массы станции (на сегодняшний день она ориентировочно составляет 417 тонн) выдержит вход в атмосферу и достигнет поверхности Земли. Речь идет о падении от 24,3 до 78,6 тонн (от 53,5 тысячи до 173,25 тысячи фунтов в американской мере весов) мусора.

Как отмечают авторы отчета, задача при сведении станции с орбиты состоит в том, чтобы уложить все обломки в незаселенной южной части Тихого океана. "Предполагается, что воздействие на окружающую среду будет незначительным, поскольку любые токсичные жидкости или материалы, как ожидается, сгорят во время входа в атмосферу", — говорится в документе.

При этом, считают авторы, обломки будут иметь достаточную кинетическую энергию, чтобы нанести ущерб людям, постройкам или морским судам.

В отчете также указывается, что пока нет утвержденного и согласованного плана сведения МКС с орбиты. План, составленный NASA в январе 2017 года, сейчас находится на согласовании в "Роскосмосе". При этом само NASA продолжает работать над различными техническими деталями такой операции.

По данным оператора российского сегмента МКС — Ракетно-космической корпорации "Энергия" — на конец 2016 года общая стоимость создания и поддержания работоспособности станции оценивалась в 121,6 миллиарда долларов. Из них вклад США составил 81,8 миллиарда, России — 9,3 миллиарда, Европы — 12,9 миллиарда, Японии — 14,8 миллиарда и Канады — 2,8 миллиарда долларов.

Ранее РКК "Энергия" предлагала построить транспортный корабль повышенной грузоподъемности на базе "Прогресс МС", который можно было бы использовать для сведения МКС с орбиты. Однако, как сообщалось, проект заморозили.

На случай ЧП

Помимо планового сведения с орбиты по завершении эксплуатации, NASA рассматривает и сценарии затопления МКС в случае ЧП на орбите. Основными причинами, которые могут привести к такой ситуации и немедленной эвакуации экипажа, американские специалисты называют разгерметизацию из-за удара метеорита или космического мусора (вероятность 1 к 120), пожара (1 к 46 тысячам) или выделения во внутренний объем станции токсичного аммиака (1 на 5,6 миллиона).

В случае разгерметизации у руководства полетом будет только 180 суток на затопление станции. Именно на такой срок работы в разгерметизированном объеме рассчитана авионика в российском сегменте МКС, откуда ведется управление двигателями.

В документе утверждается, что у NASA нет на случай ЧП четкого плана действий, который предполагал бы безопасное затопление МКС в океане. Кроме того, на такой маневр потребуется больше топлива, чем запасено на станции, а значит, на безжизненную станцию придется отправлять несколько грузовых кораблей с топливом и все это время поддерживать ее орбиту.

Кроме того, из-за сокращения количества запусков российских грузовиков "Прогресс" после 2021 года может возникнуть проблема с доставкой топлива на МКС. "Без альтернативы у NASA есть риск получить недостаток ракетного топлива для гарантированного и контролируемого сведения станции в экстренной ситуации", — говорится в отчете.

Поэтому в июле NASA провело тестовую коррекцию орбиты МКС с помощью американского частного грузового корабля Cygnus, чтобы протестировать саму возможность использования какой-то другой космической техники, кроме "Прогрессов".

ЦитироватьКоммерческие структуры пока не способны содержать МКС, заявили в НАСА
11:22 02.08.2018

МОСКВА, 2 авг — РИА Новости. Коммерческие компании не имеют достаточных средств для эксплуатации Международной космической станции и текущие планы НАСА по этому вопросу малоосуществимы, говорится в аудиторском отчете офиса генерального инспектора НАСА, опубликованном на сайте агентства.
Спойлер
"Мы признаем, что планируемые агентством усилия находятся на ранней стадии, и мы подтверждаем наши выводы, что это будет трудно для НАСА способствовать коммерческим интересам в управлении станцией, учитывая высокие расходы на ее содержание в 1,2 миллиарда долларов США. Для этого потребуется достаточный "бизнес кейс", благодаря которому коммерческие компании смогут развивать самостоятельный и прибыльный бизнес, независимый от федерального бюджета. На данный момент мы нашли мало примеров того, что частные компании готовы взять на себя такие высокие расходы", — говорится в документе.

В отчете указано, что НАСА тратит ежегодно на поддержание работы МКС по 3-4 миллиарда долларов США, что составляет половину бюджета агентства на пилотируемые программы.

Ранее власти США поручили НАСА после 2025 года прекратить бюджетное финансирование МКС и передать финансирование МКС частным компаниям. Составленный НАСА график такого перехода вызвал, как отмечается в документе, "яростное противодействие конгресса".

"В частности, мы задаемся вопросами о том, существуют ли достаточное экономическое обоснование, при котором частные компании смогут развивать самоокупаемый и прибыльный бизнес независимо от значительного федерального финансирования в течение следующих шести лет", — говорится в отчете.

Генеральный инспектор НАСА отмечает, что проведенная аудиторская проверка планов НАСА ставит под сомнение планы агентства по увеличению коммерческой активности на околоземной орбите.

Fluid Shifts:
Спойлер
A 55S crewmember performed their Fluid Shifts Dilution Measurements activities today. They collected saliva, blood and urine at multiple points during the day and ins erted them into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). Fluid Shifts is a joint NASA-Russian experiment divided into Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut's eyes. Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is being evaluated as a possible intervention. Results fr om this study may help to develop preventative measures against lasting changes in vision and to prevention of eye damage.

Center for the Advancement of Science in Space (CASIS) Protein Crystal Growth (PCG) 11:
Спойлер
Today the crew removed the CASIS PCG 11 hardware from a Microgravity Experiment Research Locker / INcubator (MERLIN), deactivated each of the cells on a Handheld High Density Protein Crystal Growth (HDPCG) unit, and then inserted the hardware in to a MELFI. CASIS PCG 11 produces acetylcholinesterase crystals, a neurotransmitter enzyme. Crystals grown in microgravity are larger, of higher quality and can be used for a technique called macromolecular neutron crystallography to locate hydrogen atoms in the crystal's structure. These hydrogen atoms play critical roles in the enzyme's function and knowing their location clarifies the protein's structure and function. This research advances the development of better antidotes to fatal organophosphate nerve agents, which act by inhibiting acetylcholinesterase in the nervous system.

The SpaceX Dragon resupply ship, on its 15th Commercial Resupply Services mission (CRS-15), is pictured the day after it was captured and installed on the Harmony module. The orbital complex was flying over northern central China near the Mongolian border at the time this photograph was taken.

The International Space Station Partners and mission managers polled "go" for tomorrow's release of the SpaceX Dragon cargo craft for its deorbit and splashdown in the Pacific Ocean to wrap up the CRS-15 mission.
Спойлер
With favorable weather conditions forecast in the splashdown zone, Dragon's hatch will be closed early Friday around 3 a.m. Central time. Robotic ground controllers will then use the Canadarm2 robotic arm to detach Dragon from the Earth-facing port of the Harmony module around 5:30 a.m. Central time and will maneuver Dragon into the release position.

With Expedition 56 Flight Engineer Serena Auñón-Chancellor of NASA monitoring Dragon's systems, the ground controllers will release Dragon from Canadarm2 at 11:37 a.m. Central time. After its release, Dragon will conduct a series of "departure" burns to move to a safe distance away from the station.

Several hours later, at 4:23 p.m. Central time, SpaceX flight controllers at Hawthorne, California will command Dragon's engine to fire for 12 minutes and 53 seconds in the deorbit burn that will enable Dragon to slip out of orbit for its descent back to Earth.

Dragon's parachute-assisted splashdown is scheduled at 5:17 p.m. Central time, 3:17 p.m. Pacific time, about 410 miles southwest of Long Beach, California. It will take about two days for Dragon to be brought back to port for its cache of cargo and scientific experiments to be unloaded.

ВАШИНГТОН, 2 авг – РИА Новости. Грузовой корабль Dragon компании SpaceX в пятницу покинет Международную космическую станцию (МКС), сообщили в НАСА.

Ориентировочно в 13.30 мск в пятницу корабль будет отстыкован от американского модуля "Грамония" (Harmony), но останется прикрепленным к механическому манипулятору Canadarm2 еще несколько часов.

На сегодняшний день Dragon является единственным космическим кораблем, который способен доставлять грузы с МКС на Землю. Его приводнение в Тихом океане в районе побережья Калифорнии ожидают в субботу в 01.17 мск. Для Dragon это 15 грузовая миссия к МКС по контракту с НАСА. Корабль прибыл на орбиту 2 июля с 2,676 тонны груза: предметами первой необходимости, материалами для научных экспериментов.

SpaceX отрабатывает технологию многоразового использования космических аппаратов, на регулярной основе запуская в повторный полет первую ступень ракеты-носителя Falcon 9, а также повторно используя капсулу грузового корабля Dragon. Возвращающийся на Землю аппарат уже бывал на МКС в 2016 году.

The next generation of American spacecraft and rockets that will launch astronauts to the International Space Station are nearing the final stages of development and evaluation. NASA's Commercial Crew Program will return human spaceflight launches to U.S. soil, providing safe, reliable and cost-effective access to low-Earth orbit on systems that meet our safety and mission requirements. To meet NASA's requirements, the commercial providers must demonstrate that their systems are ready to begin regular flights to the space station. Two of those demonstrations are uncrewed flight tests, known as Orbital Flight Test for Boeing, and Demo-1 for SpaceX. After the uncrewed flight tests, both companies will execute a flight test with crew prior to being certified by NASA for crew rotation missions. The following schedule reflects the most recent publicly releasable dates for both providers.

Targeted Test Flight Dates:
Boeing Orbital Flight Test (uncrewed): late 2018 / early 2019
Boeing Crew Flight Test (crewed): mid-2019
SpaceX Demo-1 (uncrewed): November 2018
SpaceX Demo-2 (crewed): April 2019

U.S. Cargo Ship to Depart International Space Station with Critical Scientific Research

After delivering more than 5,900 pounds of science and supplies, a SpaceX Dragon cargo spacecraft will depart the International Space Station on Friday, Aug. 3 at 12:37 p.m. EDT and splash down in the Pacific Ocean about 6:17 p.m.

Ground controllers will use the space station's Canadarm2 robotic arm to detach Dragon from the Earth-facing side of the station's Harmony module and maneuver the vehicle into its release position. Expedition 54 Flight Engineer Serena Auñon-Chancellor of NASA will monitor its departure as the spacecraft is released through ground-controlled commands.

Dragon's thrusters will fire to move the spacecraft a safe distance from the station before SpaceX flight controllers in Hawthorne, California, command its deorbit burn. The SpaceX recovery team will retrieve Dragon and more than 3,800 pounds of cargo. This will include science samples from human and animal research, biology and biotechnology studies, physical science investigations and education activities.

The Space Algae investigation sequenced the entire genome of an algae population grown in space to identify genes related to growth. Algae may perceive microgravity as physical rather than biological stress, which can trigger production of oils that may help mitigate the harmful effects of microgravity and cosmic radiation during spaceflight, consume waste carbon dioxide, and provide basic human nutrition.

A cellular biology investigation (Micro-12) aims to understand how microgravity affects the growth, gene expression and the ability of a model bacterium to transfer electrons through its cell membrane along bacterial nanowires it produces. Such bacteria could be used in fuel cells to make electricity from waste organic material.

Endothelial Cells in Microgravity as a Model System for Evaluation of Cancer Therapy Toxicity (Angiex Cancer Therapy) examines whether endothelial cells cultured in microgravity represent a valid model to test effects of vascular-targeted agents on normal blood vessels. Endothelial cells are the tissue that form a single layer of cells lining blood vessels and the heart, and all other organs. Angiex was developed as a potential treatment that targets tumor cells, but a better model is needed for future testing. The study may facilitate a cost-effective method that avoids animal testing and can develop safer and more effective drugs to combat circulatory diseases.

Dragon will also be returning a Latching End Effector that was removed from the station's robotic arm to be refurbished on Earth and returned to the orbiting complex as a spare.

NASA and the Center for the Advancement of Science in Space (CASIS), the nonprofit organization that manages research aboard the U.S. national laboratory portion of the space station, will receive time-sensitive samples and begin working with researchers to process and distribute them within 48 hours of splashdown.

Dragon, the only space station resupply spacecraft currently able to return to Earth intact, launched June 29 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, and arrived at the station July 2, for the company's 15th NASA-contracted commercial resupply mission to the station.
