ISS Daily Summary Report - 12/08/2020

NanoRacks Module-9:

 Скрытый текст:

The crew performed activation of eleven mixture tubes for the Module-09 experiment containing numerous experiment projects. NanoRacks Module-09 is a combination of 35 experiments provided by school students from 5 different countries. The experiments are housed within a NanoRacks Module container and is a combination of biological static experiments and some experiments that require crew interaction to mix materials to activate. The experiments within the module are returned to the ground for analysis.

Vascular Echo:

 Скрытый текст:

The crew performed a 13 hour blood pressure monitoring session for the Vascular Echo study. Cardiac and Vessel Structure and Function with Long-Duration Space Flight and Recovery (Vascular Echo) examines changes in blood vessels, and the heart, while the crew members are in space, and then follow their recovery on return to Earth. The results could provide insight into potential countermeasures to help maintain crewmember health, and quality of life for everyone.

Rotifer-B2:

 Скрытый текст:

The crew installed eight Rotifer B2 Experiment Containers in Kubik 5 and eight Rotifer B2 Experiment Containers in Kubik 6. The crew then removed each Experiment Container and gently shook each in order to displace bubbles from samples and then reinstalled them back into the Kubik facilities. Historical photos were taken of a crewmember shaking the containers.

Space Organogenesis:

 Скрытый текст:

The crew prepared samples of the Space Organogenesis experiment and initiated rotation sessions as well as periodic observation checks. The Development of Advanced 3D Organ Culture System Utilizing the Microgravity Environment (Space Organogenesis) investigation demonstrates growth of organ buds from human stem cells in three-dimensional (3D) cultures in microgravity. Researchers plan to use these cultures to observe growth of the organ buds and analyze changes in gene expression. Cell culture on Earth needs supportive materials or forces to achieve 3D growth, but in microgravity cell cultures likely can expand into three dimensions without those devices.

MVP (Multi-use Variable-g Platform) Cell-06:

 Скрытый текст:

The crew took historical documentation photos and installed eight Cell-06 Experiment Modules into the Multi-use Variable-g Platform. The Cartilage-Bone-Synovium Micro-Physiological System Investigation Using the Multi-purpose Variable-G Platform (MVP Cell-06) develops a biological model to study the effects of spaceflight on musculoskeletal disease. Traumatic joint injury may lead to arthritis after loss of cartilage and bone, a disease called post-traumatic osteoarthritis. This investigation could lead to drugs to prevent the progression of this disease.

PAUL (Powered Ascent Utility Lockers):

 Скрытый текст:

The crew uninstalled PAUL units s/n 001 and 002 from the Dragon and installed them into the Columbus Express Rack. Crew took front photos of front of installed units. The PAUL is reconfigurable hardware that provides power to payloads during ascent to the space station. That makes it possible to control temperature and other conditions for investigations during their trip to the space station, expanding the possibilities for research aboard the orbiting laboratory.

Cardinal Heart:

 Скрытый текст:

The crew installed the CO₂ controller into SABL-1 (Space Automated Bioproduct Lab) and relocated Cardinal Heart Tissue Habitats (4) from SABL-2 to SABL-1. Media bags were also placed into cold stowage. Effect of Microgravity on Drug Responses Using Engineered Heart Tissues (Cardinal Heart) studies the effects of change in gravitational force on cardiovascular cells at the cellular and tissue level using engineered heart tissues (EHTs). Microgravity significantly affects heart tissues that perform work and exert an opposite force to gravity and is known to cause molecular and structural abnormalities in cells and tissues that can lead to disease. The investigation could provide new understanding of similar heart issues on Earth and help identify new treatments.

Rodent Research-10 (RR-10):

 Скрытый текст:

The crew installed four Rodent Habitats into Express Racks and powered up each unit in preparation for Rodent transfers. Tissue degeneration and failure of tissue to regenerate normally in microgravity are becoming increasing concerns for sustaining life in space. The CDKN1a/p21 pathway is known to be a key molecular mechanism involved in inhibiting tissue regenerative processes, and scientific evidence suggest it is required for the arrest of regenerative bone formation observed in microgravity.

STaARS BioScience-4 (Space Technology and Advanced Research Systems):

 Скрытый текст:

The crew installed four STaARS Experiment Controllers and two Experiment Containers into STaARS-1 Experiment Facility.

Posted Dec 9, 2020 at 1:06 pm


NASA astronauts (from left) Michael Hopkins and Victor Glover are pictured before opening the hatch to the newly docked SpaceX Cargo Dragon vehicle.

The Expedition 64 crew kicked off an array of new space biology experiments delivered this week aboard the SpaceX Cargo Dragon. The International Space Station residents will be gaining unique insights about the human heart, muscles and stem cells that only microgravity can provide.

NASA astronaut Kate Rubins started looking at cardiovascular cells inside the Life Science Glovebox today for the Cardinal Heart study. She serviced samples to help scientists understand the aging and weakening of heart muscles to provide new treatments for humans on Earth and astronauts in space.

Mice are being set up inside specialized habitats today so researchers can continue studying how weightlessness affects the musculoskeletal system. NASA Flight Engineers Shannon Walker, Victor Glover and Michael Hopkins removed several dozen rodents from the Cargo Dragon vehicle and placed them inside the U.S. Destiny laboratory module. Observations may enable advanced drug delivery systems to treat muscle diseases on Earth and prevent muscle atrophy in space.

JAXA astronaut Soichi Noguchi continued his stem cell research today to enable organ growth and understand genetic changes in space. The three-time space visitor viewed cell samples today with a microscope in the Kibo laboratory module to benefit organ transplant and regenerative technology.

Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov spent Wednesday working on Russian life support systems and science experiments. The duo worked on water transfers and air vent cleaning before setting up hardware to observe Earth's atmosphere at different wavelengths.

ISS Daily Summary Report - 12/10/2020

Cardinal Heart:

 Скрытый текст:

The crew deployed and used the Life Science Glovebox to change the media in the remaining Cardinal Heart Tissue Habitats. Effect of Microgravity on Drug Responses Using Engineered Heart Tissues (Cardinal Heart) studies the effects of change in gravitational force on cardiovascular cells at the cellular and tissue level using engineered heart tissues (EHTs). Microgravity significantly affects heart tissues that perform work and exert an opposite force to gravity and is known to cause molecular and structural abnormalities in cells and tissues that can lead to disease. The investigation could provide new understanding of similar heart issues on Earth and help identify new treatments.

Fiber Optic Production (FOP):

 Скрытый текст:

The crew performed sample changeouts in the Fiber Optic Production facility. The Fiber Optic Production investigation creates optical fibers with high commercial value aboard the ISS using a blend of zirconium, barium, lanthanum, sodium, and aluminum called ZBLAN. It operates in the Microgravity Science Glovebox (MSG). Extensive theoretical studies along with a limited number of experimental studies suggest that ZBLAN optical fibers produced in microgravity should exhibit far superior qualities to those produced on Earth. The resulting optical fiber from Fiber Optic Production is expected to help verify these studies and guide further engineering efforts to manufacture high value optical fiber in large volume aboard the ISS.

AstroRad Vest:

 Скрытый текст:

The crew donned the AstroRad vest and provided preliminary feedback to the investigation team in preparation for a longer vest donning session. The AstroRad vest is a personal protective equipment (PPE) device which functions as a radiation shield for astronauts. The AstroRad shields astronauts from space-borne ionizing radiation in an efficient way, provides operational simplification, and allows for the use of recycled material on-board the vehicle. The concept behind the AstroRad evolved from a commercially available device, the 360 Gamma shield, made by StemRad Ltd., which is an effective wearable shield for first responders to radiation incidents on the Earth.

BRE (Burning Rate Emulator):

The crew performed O₂/N₂ gas bottle changes and C₂H₄ fuel bottle changes in preparation for upcoming BRE runs. The Burning Rate Emulator (BRE) investigation is conducted in the Combustion Integrated Rack (CIR) on the International Space Station (ISS), as part of the Advanced Combustion via Microgravity Experiments (ACME) project. In this fire safety study, the flammability of solid and liquid materials is simulated by burning gaseous fuels under key conditions corresponding to the solid and liquid materials. This technique has been demonstrated for a wide variety of materials in normal-gravity and could provide an efficient way to screen and select fire-resistant materials for use in spacecraft, if the technique is similarly effective in microgravity.

APM (Airborne Particulate Monitor):

 Скрытый текст:

The crew transferred APM data to the ground and moved the hardware from Node 2 to the LAB. Air quality in crewed spacecraft is important for keeping astronauts healthy and comfortable. Although requirements exist for maximum allowable concentrations of particulate matter, currently no measurement capability verifies whether these requirements are met. The Airborne Particulate Monitor (APM) demonstrates an instrument for measuring and quantifying the concentration of both small and large particles in spacecraft air. The data can be used to create a map of air quality in terms of particles and shed light on the sources of such particles.

NanoRacks Module-9:

 Скрытый текст:

The crew performed the 2nd operations of sample tube mixtures. NanoRacks Module-09 is a combination of 35 experiments provided by school students from 5 different countries.

Система получения кислорода "Электрон-ВМ" вновь отключилась на МКС
12.12.2020 14:53:50
       Москва. 12 декабря. ИНТЕРФАКС - Система получения кислорода "Электрон-ВМ" на Международной космической станции (МКС) в очередной раз вышла из строя из-за проблем с давлением, сообщил экипаж станции во время переговоров с Землей.
      "Электрон" отключился не из-за проблем с питанием, а из-за проблем с давлением кислорода", - сказал космонавт Сергей Рыжиков в ходе переговоров с ЦУПом, трансляцию которого ведет NASA.
       По его словам, сбой произошел около 11:50.
       За последние два месяца система получения кислорода на МКС выходила из строя, как минимум, пять раз. Сообщалось о сбоях в работе "Электрона" 14, 17, 19 и 21 октября, а также 10 декабря. В "Роскосмосе" заявили, что ситуация не угрожала жизни и здоровью экипажа.
       Система "Электрон" располагается на российском сегменте МКС в модуле "Звезда". Во время ремонта системы работает дублирующая система в американском сегменте станции.

 Скрытый текст:

       С августа 2020 года экипаж МКС занимается поиском и устранением утечки воздуха в российском модуле "Звезда". Высказывается мнение, что разгерметизация может быть связана с возрастом станции. Такой точки зрения придерживается, в частности, космонавт Иван Вагнер, вернувшийся со станции в октябре.
       Со своей стороны исполнительный директор "Роскосмоса" Сергей Крикалев отверг утверждения об увеличении числа поломок на станции и заявил, что модули МКС способны проработать существенно дольше своего гарантийного срока.
       Замглавы ракетно-космической корпорации "Энергия" Владимир Соловьев ранее сообщил, что в корпорации прогнозируют "лавинообразный выход из строя многочисленных элементов на борту МКС" после 2025 года.
       Ранее глава "Роскосмоса" Дмитрий Рогозин заявил, что Россия готовится к созданию новой орбитальной станции.

МОСКВА, 12 декабря. /ТАСС/. Система подачи кислорода "Электрон-ВМ" на Международной космической станции отказала после выключения пылесоса. Об этом доложил космонавт Сергей Рыжиков во время переговоров с Центром управления полетами (ЦУП), трансляция которых ведется на сайте NASA.

"Отказ прошел в 08:58 (11:59 мск)", - отметил Рыжиков, уточнив, что это произошло после отключения пылесоса.

Специалист ЦУП назвал отключение аварийным и пояснил, что систему нужно отключить грамотно.

Ранее космонавты проводили тестовые включения пылесоса. Бортовой компьютер выдал несколько ошибок. Затем они выключили пылесос, чтобы "выполнить уборку руками".

 Скрытый текст:

Система подачи кислорода выходила из строя в октябре. В конце месяца экипаж станции под руководством главной оперативной группы управления разобрал систему и изучал ее на предмет неисправностей. На время ремонтных работ задача по подаче воздуха была переброшена на дублирующую систему, находящуюся на американском сегменте.

В четверг в пресс-службе Роскосмоса сообщили ТАСС, что работа системы "Электрон-ВМ" восстановлена.

О системе
"Электрон-ВМ" предназначена для подачи кислорода экипажу МКС. Его разработчиком является НИИхиммаш. Система способна вырабатывать от 25 до 160 литров кислорода в час и дополнительно от 50 до 320 литров водорода в час. Принцип действия основан на электролизе воды с щелочным электролитом в проточном электролизере, после чего происходит разделение газожидкостной смеси. На станции имеются запасы кислорода, также в американском модуле "Транквилити" есть своя система генерации кислорода.

Грузовые корабли "Прогресс" будут летать к МКС медленнее предшественников
МОСКВА, 14 дек - РИА Новости. Российские грузовые корабли "Прогресс" в 2021 году будут летать к Международной космической станции двое суток, а не несколько часов, как их предшественники, следует из программы полета станции, составленной РКК "Энергия" (предприятие "Роскосмоса") и имеющейся в распоряжении РИА Новости.
С 2012 года "Прогрессы" стали летать к МКС по быстрой шестичасовой схеме вместо двухсуточной. С 2018 года они перешли на сверхбыструю трехчасовую схему. Обе схемы - шестичасовая и трехчасовая - после отработки на "Прогрессах" были внедрены на пилотируемых кораблях "Союз" - соответственно в 2013 и 2020 годах.
Согласно программе полета МКС в следующем году, корабли "Прогресс МС-16", МС-17 и МС-18, запуски которых намечаются соответственно на 15 февраля, 30 июня и 28 октября, будут летать к МКС по двухсуточным схемам.
Два источника РИА Новости в ракетно-космической отрасли подтвердили данную информацию, добавив, что запросов на использование быстрой и сверхбыстрой схем для "Прогрессов" в 2021 году не поступало. Представитель пресс-службы "Роскосмоса" сообщил агентству, что "график полетов на следующий год еще не утвержден".
Быстрая схема позволяет немного сэкономить топливо, но для этого необходимо подстраивать орбиту станции. Эту схему отрабатывали на грузовых "Прогрессах", чтобы потом применять на пилотируемых "Союзах". Однако подстраивать орбиту станции и под пилотируемые корабли, и под грузовые достаточно затруднительно.
Корабли "Прогресс" используются для доставки на станцию грузов для экипажа, топлива, кислорода, воздуха и питьевой воды. С их помощью также проводятся коррекции высоты орбиты МКС и ее увод от столкновения с космическим мусором. С 1978 года осуществлены 167 запусков кораблей "Прогресс" различных модификаций, три из которых не добрались до МКС из-за аварий ракет-носителей в 2011, 2015 и 2016 годах.

Assessment of Nutritional Value and Growth Parameters of Space-grown Plants (Plant Habitat-02) cultivates radishes as a model plant that is nutritious and edible, has a short cultivation time, and is genetically similar to Arabidopsis, a plant frequently studied in microgravity. Developing the capability for food production in space requires understanding cultivation conditions such as intensity and spectral composition of light and the effects of the culture medium or soil. This research could help optimize plant growth in the unique environment of space, as well as evaluation of nutrition and taste of the plants

Space Organogenesis:

 Скрытый текст:

The crew performed sample inserts and sample fixations for the Space Organogenesis experiment and then performed the closeout procedures. The Development of Advanced 3D Organ Culture System Utilizing the Microgravity Environment (Space Organogenesis) investigation demonstrates growth of organ buds from human stem cells in three-dimensional (3D) cultures in microgravity. Researchers plan to use these cultures to observe growth of the organ buds and analyze changes in gene expression. Cell culture on Earth needs supportive materials or forces to achieve 3D growth, but in microgravity cell cultures likely can expand into three dimensions without those devices.

Expedition 64 Flight Engineer Kate Rubins works inside the Life Sciences Glovebox conducting research for the Cardinal Heart study.

Cardiac research and orbital plumbing were the Monday highlights for the Expedition 64 crew aboard the International Space Station.

Flight Engineer Kate Rubins peered through a microscope at heart tissue samples today for the Cardinal Heart study. The microgravity study may provide new insights and advanced therapies for heart conditions on Earth and in space.

For the Vascular Echo experiment today, Flight Engineer Victor Glover strapped on a Doppler probe to his right leg to scan his femoral artery during a light exercise session. The cardiovascular study, running since March 2015 on the orbiting lab, is looking at how living in space stiffens the arteries.

A brand new, advanced toilet, delivered Oct. 5 on the 14th Cygnus resupply mission, is being installed on the space station today. NASA astronauts Michael Hopkins and Shannon Walker put on their plumber caps today to assemble and install the Universal Waste Management System in the Tranquility module. The station's second space bathroom was designed to be better integrated with water systems, as well as smaller, lighter, easier to use and more comfortable.

In the Russian segment of the station, Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov focused on cargo transfers and inventory updates. The duo is packing the Progress 76 resupply ship with trash and discarded gear for its departure from the Pirs docking compartment in February.

Early Saturday morning, an unexplained power glitch resulted in a loss of power to some International Space Station systems that are operated by one of eight power channels for the complex (4B channel). The crew was never in any danger, and the affected systems were repowered in a short period of time by one of the other station's power channels (4A).

As of Monday morning, all impacted station systems are operating normally while flight controllers in Mission Control review data to try to assess the cause of the problem and a forward plan of remedial action.

ISS Daily Summary Report - 12/14/2020

AstroRad Vest:

 Скрытый текст:

The crew completed a range-of-motion and test with and without the vest installed, and then completed a general survey. The AstroRad vest is a personal protective equipment (PPE) device which functions as a radiation shield for astronauts. The AstroRad shields astronauts from space-borne ionizing radiation in an efficient way, provides operational simplification, and allows for the use of recycled material on-board the vehicle. The concept behind the AstroRad evolved from a commercially available device, the 360 Gamma shield, which is an effective wearable shield for first responders to radiation incidents on the Earth.

Cardinal Heart:

 Скрытый текст:

The original plan for today was to perform microscopy observations of the cells growing in the habitats. However, it took extra time for the crew to achieve a configuration which allowed good focus with the microscope. Due to this, the microscopy observations were deferred. Effect of Microgravity on Drug Responses Using Engineered Heart Tissues (Cardinal Heart) studies the effects of change in gravitational force on cardiovascular cells at the cellular and tissue level using engineered heart tissues (EHTs). Microgravity significantly affects heart tissues that perform work and exert an opposite force to gravity and is known to cause molecular and structural abnormalities in cells and tissues that can lead to disease. The investigation could provide new understanding of similar heart issues on Earth and help identify new treatments.

ISS Experience:

 Скрытый текст:

The crew set up the ISS Experience hardware in preparation for an off-load of the data from the previous session. The International Space Station Experience (The ISS Experience) is a cinematic virtual reality (VR) series documenting life and research aboard the space station. Filmed over multiple months, the immersive VR series documents different crew activities - from science conducted aboard the station to preparation for a spacewalk. The ISS Experience uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.

Micro-14A:

 Скрытый текст:

The crew performed the operations needed to collect samples from the 12-well plate, and then inserted the samples into MELFI (Minus Eighty Degree Laboratory Freezer for ISS) for preservation. The Characterizing the Effects of Spaceflight on the Candida albicans Adaptation Response (Micro-14) investigation aboard the International Space Station (ISS) extends previous flight and ground-based studies on an opportunistic yeast, Candida albicans, to define mechanisms that lead to cellular adaptation responses to the spaceflight environment. As an opportunistic pathogen, C. albicans is capable of causing severe, life-threatening illness in immunocompromised hosts. This investigation seeks to evaluate the responses of the microorganism to microgravity conditions and, in particular, to assess changes at the physiological, cellular, and molecular level and to characterize virulence factors.

Phospho-Aging:

 Скрытый текст:

The crew collected blood and urine samples in support of the Phospho-aging experiment, and inserted them into MELFI (Minus Eighty Degree Laboratory Freezer for ISS) for preservation. JAXA's Phospho-aging Mechanism of Accelerated Aging Under Microgravity (Phospho-aging) examines the molecular mechanism behind aging-like symptoms, such as bone loss and muscle atrophy, that occur more rapidly in microgravity. Using analysis of human premature-aging syndromes (progeria) in mouse models, scientists identified calciprotein particles (CPPs) as a pro-aging factor in mammals. CPPs behave like a pathogen, inducing chronic inflammation and systemic tissue damage that could be the mechanism behind accelerated aging in space.

Universal Waste Management System (UWMS):

 Скрытый текст:

The crew gathered the hardware and began assembling the toilet. Due to issues encountered with removing and installing seals on the toilet assembly, the crew was directed to stand down on activities while teams meet to discuss the issue and a forward plan. UWMS demonstrates the technology and long-term use of a compact toilet and the Urine Transfer System (UTS), which provides automated control of flow into the Urine Processor Assembly (UPA) or storage containers, which allow simultaneous use of both toilets. Automated offload of backup storage saves crew member time. The UWMS's smaller footprint and improved technology support possible expansion of space station crew and future long-term, deep-space exploration.

Vascular Aging:

 Скрытый текст:

The crew participated in a science session which included the use of the Bio-Monitor device to record several days of physiological data, and the collection of blood samples to assess glucose tolerance. Emerging data point towards linkages among cardiovascular health risk, carotid artery aging, bone metabolism and blood biomarkers, insulin resistance, and radiation. Data indicate that aging-like changes are accelerated in many International Space Station (ISS) crew members, particularly with respect to their arteries. As part of the Space Environment Causes Acceleration of Vascular Aging: Roles of Hypogravity, Nutrition, and Radiation (Vascular Aging) investigation, ultrasounds of the arteries, blood samples, oral glucose tolerance, and wearable sensors from ISS crew members are analyzed.

Vascular Echo:

 Скрытый текст:

The crew set up the appropriate hardware, marked the right leg femoral artery, and performed Doppler scans around an exercise session. Cardiac and Vessel Structure and Function with Long-Duration Space Flight and Recovery (Vascular Echo) examines changes in blood vessels, and the heart, while the crew members are in space, and then follow their recovery on return to Earth. The results could provide insight into potential countermeasures to help maintain crewmember health, and quality of life for everyone.

Critical Bus Loss:

 Скрытый текст:

On Saturday 4B Channel experienced a critical bus loss. Ground controllers cross-tied Channel 4B to 4A and repowered DDCU S14B and DDCU S04B. Critical system loads were recovered including CMG 4, KU Band A/G 2 and AMS control computer. Teams are meeting to discuss the cause and a forward plan.

Internal Thermal Control System (ITCS) Water Sampling:

 Скрытый текст:

The crew performed this routine activity to take fluid samples from the Lab, Node 2 (N2), Node 3 (N3) and Japanese Experiment Module (JEM). The samples will be returned to the ground for analysis.

Extravehicular Activity (EVA) AirLock (AL) Unstow:

 Скрытый текст:

The crew unstowed items from the Airlock to clear space for this week's planned Extravehicular Mobility Unit (EMU)s 3004 and 3015 loop scrub and Secondary Control Unit (SCU) R&R.

Waste and Hygiene Compartment (WHC) Pre-Treat Tank Remove & Replace (R&R): The crew R&Rd the WHC pre-treat tank. During closeout the EK hose was inspected for particulates. This activity is nominal, scheduled maintenance.

Expedition 64 Flight Engineer Victor Glover reviews research procedures for an experiment that could accelerate the development of advanced therapies that target cancer cells.

The Expedition 64 crew continues exploring how microgravity affects the heart to improve health for humans on and off the Earth. Northrop Grumman has booked its next Cygnus resupply mission to the International Space Station for early next year.

NASA Flight Engineers Kate Rubins and Michael Hopkins partnered up today for the Cardinal Heart study to learn how to treat aging and weakening heart cells. Hopkins peered at heart tissue samples through a microscope while Rubins serviced those samples in the Kibo laboratory module's Life Sciences Glovebox.

Blood sample collections were on the morning schedule for Flight Engineer Victor Glover as he took glucose measurements for the Vascular Aging study. He then moved on to a space manufacturing study that seeks to vastly improve the production and quality of optic fibers.

On the maintenance front, JAXA astronaut Soichi Noguchi serviced U.S. spacesuits throughout Tuesday scrubbing cooling loops in the U.S. Quest airlock. NASA Flight Engineer Shannon Walker continued installing and outfitting the station's new bathroom, the Universal Waste Management System, in the Tranquility module.

Commander Sergey Ryzhikov worked during the morning replacing components inside the Zvezda service module's treadmill then moved on to cargo transfers inside the Progress 76 resupply ship. Flight Engineer Sergey Kud-Sverchkov swapped fuel bottles inside the Combustion Integrated Rack research facility before configuring life support and communications hardware

Northrop Grumman has announced Feb. 20 for the launch of its Cygnus space freighter to the space station with several tons of cargo to resupply the crew. Cygnus will take a two-day trip to the orbiting lab before it is captured with the Canadarm2 robotic arm and installed to the Unity module where it will stay for two months.
