Four astronauts will venture outside the International Space Station for three spacewalks in January to complete battery upgrades and finalize repairs to an invaluable cosmic ray detector.

Expedition 61 Flight Engineers Jessica Meir and Christina Koch of NASA are scheduled to conduct spacewalks Wednesday, Jan. 15, and Monday, Jan. 20, to finish replacing nickel-hydrogen batteries with new lithium-ion batteries that store power generated by the station's solar arrays on the station's port truss.

Assuming the battery work goes as planned, NASA astronaut Andrew Morgan and space station Commander Luca Parmitano of ESA (European Space Agency) will exit the station Saturday, Jan. 25, to finish installing the Alpha Magnetic Spectrometer's (AMS) new cooling apparatus and lines begun in November and December, and verify they are ready for use.

Live coverage of all three spacewalks will begin at 5:30 a.m. EST on NASA Television and the agency's website.

These will be the second and third spacewalks for Meir, who will be extravehicular crew member 1 (EV1) for both spacewalks. Koch, who will be extravehicular crew member 2 (EV2), will perform the fifth and sixth spacewalks of her career.

Morgan, who will be EV1 for the AMS spacewalk, and Parmitano, who will be EV2, performed the three previous spacewalks to repair the spectrometer, which is searching for dark matter and antimatter in the universe using the station's unique location and capabilities for scientific research.

The spacewalks will be the 225th, 226th and 227th in support of space station assembly and maintenance.

The Expedition 61 crew gathers together for a meal. Clockwise from top left are, Christina Koch, Oleg Skripochka, Luca Parmitano, Alexander Skvortsov, Jessica Meir and Andrew Morgan.

The Expedition 61 crew is gearing up for the first three spacewalks of 2020 set for this month. Meanwhile, the International Space Station is bustling with an array of microgravity research activities today.

NASA astronauts Jessica Meir and Christina Koch will conduct the first two spacewalks scheduled for Jan. 15 and Jan. 20. The duo will finish replacing older nickel-hydrogen batteries with new lithium-ion batteries on the station's Port-6 truss structure. They spent Wednesday reviewing spacewalk procedures and inspecting spacesuit tethers.

The next spacewalk would be Jan. 25 following the successful battery replacements. NASA astronaut Andrew Morgan and Commander Luca Parmitano of ESA (European Space Agency) will finish the repair work they started in November on the station's cosmic particle detector, the Alpha Magnetic Spectrometer.

In the midst of the spacewalk preparations, the lab residents kept up the ongoing space science to improve life for humans on and off Earth.

Morgan began the day installing botany research gear inside Japan's Cell Biology Experiment Facility before transferring resupply racks to the Cygnus space freighter. Parmitano conducted a vision test then cleaned up Rodent Research hardware that housed mice that were returned to Earth aboard the SpaceX Dragon cargo craft.

Cosmonauts Alexander Skvortsov and Oleg Skripochka split their time on Russian science and maintenance tasks. The duo partnered together for a study exploring piloting methods under a variety of gravity conditions. Skvortsov then measured the station's radiation environment as Skripochka replaced fuel bottles for combustion research.

ISS Daily Summary Report – 1/08/2020

Rodent Research-19 (RR-19):

The crew completed the Life Science Glovebox Cleaning activity. Mighty Mice in Space: Preclinical Evaluation of a Broad Spectrum Myostatin Inhibitor to Prevent Muscle and Bone Loss Due to Disuse uses rodent models on the ISS to investigate the potential benefits of targeting the myostatin (MSTN) and activin signaling pathways to prevent skeletal muscle and bone loss during spaceflight and on the recovery of muscle and bone following return to Earth. This research could provide valuable preclinical data to support clinical trials for MSTN therapies for a wide range of conditions that affect muscle and bone health. Such research is particularly important for conditions that involve disuse muscle atrophy (muscle wasting due to immobility or lessened activity)—for example, patients recovering from hip fracture surgery, intensive care patients, and the elderly.

Combustion Integrated Rack (CIR):

As a continuation of the s-Flame experiment, the crew performed a manifold H2 and CH4 bottle exchanges. The CIR includes an optics bench, combustion chamber, fuel and oxidizer control, and five different cameras for performing combustion experiments in microgravity.

[свернуть]

Cell Biology Experiment Facility-L (CBEF-L):

The crew installed the Plant Experiment Unit into the CBEF-L facility. CBEF-L is a Japan Aerospace Exploration Agency (JAXA) new subrack facility, which is an upgraded facility of the original Cell Biology Experiment Facility (CBEF) currently aboard the International Space Station (ISS). CBEF-L provides new capabilities with additional new resources such as Full High Definition video interface, Ethernet, 24 VDC power supply, and a larger diameter centrifugal test environment. By using the original CBEF and CBEF-L as one facility for the same experiment, the payload user is provided with an upgraded experimental environment that can handle the processing of more experimental samples for a wider array of experiments.

Astronaut Jessica Meir waves during a spacewalk with fellow astronaut Christina Koch (out of frame) on Oct. 18, 2019.

Human research and space biology filled the lab schedule aboard the International Space Station today. The Expedition 61 crewmembers are also ramping up for a trio of spacewalks set to begin next week.

NASA Flight Engineer Jessica Meir and Commander Luca Parmitano of ESA (European Space Agency) started Thursday collecting their blood samples. The duo spun the samples in a centrifuge and stowed them in a science freezer for later analysis. The astronauts also joined cosmonaut Alexander Skvortsov for a series of eye checks throughout the day.

Skvortsov also partnered up with cosmonaut Oleg Skripochka for cardiac research. After some Russian lab maintenance work, the pair also filmed educational activities to promote spaceflight for audiences on Earth.

Parmitano later tested how living in microgravity influences an astronaut's perception of time. At the end of the workday, the ESA commander serviced a research incubator located in the Unity module.

Flight Engineer Andrew Morgan is setting up a mouse habitat in Japan's Kibo laboratory module. The research facility is part of the Cell Biology Experiment Facility and enables the observation of rodents, which have a physiology similar to humans, in different gravity conditions.

Meir and fellow NASA astronaut Christina Koch are getting ready for two of three spacewalks planned for this month. The spacewalkers will work outside the station on Jan. 15 and 20 to replace older batteries with newer, more powerful batteries on the orbiting lab's Port-6 truss structure. Morgan and Parmitano are targeting a third spacewalk on Jan. 25 to finish repairing the station's cosmic particle detector, the Alpha Magnetic Spectrometer.

NASA astronaut Christina Koch works on a U.S. spacesuit, with a patch of the Italian flag on the left shoulder, that Commander Luca Parmitano of ESA (European Space Agency) wore during a spacewalk on Dec. 2, 2019.

The Expedition 61 crew is continuing more research today into how the human body adapts to living in microgravity. U.S. spacesuits aboard the International Space Station are also being readied for the first of three spacewalks planned to start Jan. 15.

Eye checks were on the schedule Friday afternoon as astronauts Jessica Meir and Christina Koch took turns as Crew Medical Officer. The duo scanned the eyes of NASA Flight Engineer Andrew Morgan and Commander Luca Parmitano of ESA (European Space Agency) using an ultrasound device and optical coherence tomography gear.

Morgan started the morning setting up a specialized mouse habitat that can create artificial gravity conditions aboard the orbiting lab. Mice physiology resembles that of humans, providing scientists fundamental insights into cellular and genetic alterations that occur in weightlessness.

Meir is getting the spacesuits ready she and Koch will wear on Jan. 15 and 20 for a pair of power maintenance spacewalks. She scrubbed cooling loops and filled water tanks before checking out suit hardware and checking for leaks. The spacewalking duo will replace older batteries with newer, more powerful batteries on the orbiting lab's Port-6 truss structure.

In the Russian segment of the space station, cosmonauts Alexander Skvortsov and Oleg Skripochka focused on life support maintenance and orbital plumbing tasks. Skvortsov also researched how microgravity affects pain sensation while Skripochka photographed the condition of space-exposed hardware.

Выход космонавтов в космос с борта МКС отложили на неопределенный срок
03:04 11.01.2020 (обновлено: 03:16 11.01.2020)

МОСКВА, 11 янв - РИА Новости. Выход российских космонавтов в открытый космос, планировавшийся на 15 января, не состоится, сообщил РИА Новости представитель пресс-службы Центра подготовки космонавтов (ЦПК); по информации источника агентства в ракетно-космической отрасли, новых сроков пока нет.

В декабре другой источник агентства в отрасли рассказал, что выход Александра Скворцова и Олега Скрипочки с борта МКС планируется на 15 января, но сроки его проведения зависят от решения НАСА. Он пояснил, что космонавты должны заменить сменную панель системы терморегулирования модуля "Заря", который построен Россией на деньги США.
"Пятнадцатого января выхода в открытый космос не будет", - заявил представитель ЦПК.

"Российский выход отложен на неопределенный срок", - добавил источник в ракетно-космической отрасли. По словам собеседника агентства, это связано с тем, что в январе запланированы три выхода астронавтов с борта станции по американской программе.

Источник добавил, что проведение российского выхода с февраля по апрель маловероятно, так как в этот период на станции будет только один российский космонавт – Скрипочка. Ранее сообщалось, что 6 февраля на Землю на пилотируемом корабле "Союз МС-13" должен возвратиться Скворцов, а 9 апреля на МКС на "Союзе МС-16" предстоит прибыть Николаю Тихонову и Андрею Бабкину.

В конце декабря представитель НАСА сообщил РИА Новости, что на 15 января намечен выход в открытый космос американок Кристины Кук и Джессики Меир.

В настоящее время на борту МКС также совершают полет американец Эндрю Морган и итальянец Лука Пармитано.

ISS Daily Summary Report – 1/13/2020

Confined Combustion:

The crew continued the experiment, including an ignition of a SIBAL sample with no baffles installed, and two ignitions with the silver baffles installed (3 total ignitions completed today). The baffles are used to change the airflow path and alter the radiated heat environment around the flame. This project aims to study flame spread in confined spaces—specifically the interactions between spreading flames and surrounding walls. Flame spread in confined spaces (such as buildings and vehicles) may pose a more serious fire hazard than flame spread in open spaces because of acceleration caused by radiative heat feedback from the surrounding walls and a tunnel flow acceleration effect. However, several aspects of flame spread are difficult to study in normal gravity conditions. Gravity-driven buoyancy flow complicates the fire growth process and prohibits a fundamental understanding of the underlying physics. However, in microgravity, buoyancy is eliminated, allowing scientists to better study the physics of flame spread.

The crew completed a Food Acceptability Survey using the Data Collection Tool on an available SSC (Station Support Computer).

NASA astronauts Jessica Meir (left) and Christina Koch are pictured preparing to begin the historic first-ever all-female spacewalk on Oct. 18, 2019.

The first of three spacewalks planned for January begins Wednesday to continue upgrading International Space Station power systems and a cosmic ray detector. While the spacewalkers ready their suits and tools, the rest of the Expedition 61 crew is on science and maintenance duty today.

NASA Flight Engineer Jessica Meir is partnering for a second time with fellow NASA astronaut Christina Koch for a pair of spacewalks set for tomorrow and Jan. 20. The duo is finalizing preparations for the two six-and-a-half hour spacewalks to replace batteries that store and distribute solar power. They will set their U.S. spacesuits to internal power at 6:50 a.m. and translate out to the Port-6 truss structure. Once there they swap out old nickel-hydrogen batteries with new lithium-ion batteries. NASA TV begins its live coverage Wednesday at 5:30 a.m. EST.

A third spacewalk is planned for Jan. 25 with NASA Flight Engineer Andrew Morgan and Commander Luca Parmitano of ESA (European Space Agency). They will finish the thermal repair work on the Alpha Magnetic Spectrometer they began last year.

Meanwhile, Morgan and Parmitano were on science duty today. The astronauts took turns safely burning fabric and acrylic samples to help scientists understand how flames spread in space. Results may inform the design of fire safety products and procedures on Earth and in space. The two crewmates also drew their blood samples, spinning them in a centrifuge for later analysis.

Cosmonaut Alexander Skvortsov spent the day servicing Russian life support equipment. On the science schedule, cosmonaut Oleg Skripochka continued setting up and testing hardware that will observe the Earth's mesosphere at different wavelengths.

Вашингтон. 15 января. ИНТЕРФАКС - Американские астронавты Джессика Меир и Кристина Кук в среду выйдут в открытый космос с борта Международной космической станции (МКС) для продолжения операции по замене старых никель-водородных аккумуляторов на новые более мощные литий-ионные, сообщает Национальное управление США по аэронавтике и исследованию космического пространства (NASA).

Выход астронавтов в космический вакуум должен начаться в 07:10 во времени Восточного побережья США (15:10 мск). Ожидается, что он продлится около 6,5 часов.

Работы по замене аккумуляторов будут осуществляться на опорном сегменте фермы МКС, к которой крепится пара солнечных панелей. Обновление системы энергоснабжения станции началось еще в январе 2017 года.

Это уже второй выход в открытый космос женского дуэта американских астронавтов. Впервые в истории за борт МКС сразу две женщины выходили в октябре прошлого года. В ходе пребывания в открытом космосе, которое продолжалось около 6,5 часов, Меир и Кук успешно заменили вышедший из строя один из энергоблоков на ферме МКС, отвечающий за зарядку/разрядку внешних аккумуляторных батарей станции.

Меир и Кук предстоит выйти в открытый космос еще 20 января для завершения всех работ по замене аккумуляторов. После монтажа всех новых аккумуляторов, срок службы которых составляет 10 лет, они позволят значительно улучшить энергоснабжение МКС.

Нынешний выход в открытый космос членов экипажа МКС станет 225-м за всю истории станции.

В настоящее время экипаж станции состоит из россиян Александра Скворцова и Олега Скрипочки, американцев Эндрю Моргана, Кристины Кук и Джессики Меир, а также итальянца Луки Пармитано.
