Чем мы пишем в космосе? На 1 фото - специально разработанная для НАСА ручка. Она может работать практически в любых условиях. Чернила заправлены в стержни под давлением, т.е. они одноразовые. Но самым удобным для нас остается карандаш с дополнительными грифелями, как на 2 фото.

ISS Daily Summary Report – 4/20/2018

Mobile Servicing System (MSS) Operations / Material on ISS Experiment – Flight Facility (MISSE-FF):

Спойлер

Last night the final MISSE Sample Container (MSC) was successfully installed on the MISSE FF. All five MISSE Sample Carriers (MSC) were activated and opened. The Mobile Transporter (MT) was then translated from Work Site (WS)2 to WS6. MISSE Transfer Tray return to JEM A/L is planned next Thursday. MISSE-FF will be a permanent external platform on the ISS that is modular and robotically serviceable. Remotely controllable sample carriers will provide sample protection and on-demand picture data previously unavailable on prior experiments. Sample plates containing a variety of surface materials will be exposed to the space environment outside the ISS for varying durations to inform satellite designers on how different materials degrade over time.

Using Brachypodium distachyon to Investigate Monocot Plant Adaptation to Spaceflight (APEX-06):

Спойлер

The crew harvested the additional plants for the follow-on APEX-06 investigation run today. They took photographs of the science containers and then preserved samples and placed them into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The APEX-06 experiment investigates the growth of the common grass species Brachypodium distachyon in the microgravity environment of space. The grasses grow from seedlings aboard the ISS, and are returned as frozen samples to Earth-based labs for detailed analysis and comparison with Earth-based control groups. APEX-06 aims to compare the growth and gene-expression patterns of Brachypodium distachyon with those of the dicotyledonous model plant Arabidopsis thaliana, which has been extensively studied in space and whose behavior in microgravity is better understood.

Human Research Program (Biochemical Profile, Repository, Cell Free Epigenome and Medical Proteomics):

Спойлер

54S crewmembers collected blood and urine samples for their Flight Day 30 sessions of the Biochem Profile, Repository, Cell Free Epigenome and Medical Proteomics investigations today.

[/li]
• The Biochemical Profile investigation tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results; which scientists can use to study the effects of spaceflight on the body.
• Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. The repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.
• The JAXA Cell Free Epigenome investigation tests blood samples collected from astronauts and cellular genes are analyzed.  Blood carries molecular signals released from the cells inside the body. The analysis results provide insights to scientists on how human bodies function during space flight.
• The Medical Proteomics investigation evaluates changes of proteins in blood serum, bone and skeletal muscles after space flight, and also supports identification of osteopenia-related proteins. By combining research results for space mice, astronauts and ground patients, proteins related to osteopenia can be identified using the latest proteome analysis technique.  It is anticipated that the use of the marker proteins related to osteopenia will be of benefit in the future for assessing the health of astronauts as well as osteoporosis patients on ground.

Divert Unwanted Space Trash (DUST):

Спойлер

Today the crew took samples and photographs of various vents in the US Laboratory and Nodes 1, 2 and 3. They ins erted the samples in to cold stowage and downlinked the photographs. The DUST investigation collects and analyzes particulates in airborne debris from the ISS cabin. Unique aspects of the spacecraft environment, such as lack of gravity and no fresh air, influence the size, quantity, and components of airborne particulate matter, which in turn affects air quality aboard the station. The data also provides baseline information for future spacecraft particle detector design, and the debris can be used for realistic testing of possible particulate monitors for future long-duration missions.

There has been an increased ionic breakthrough on both WPA Multi-Filtration (MF) beds identified by a steep increase in the conductivity of the bed's effluent. The beds were previously sampled to determine the species that is saturating the bed. Those samples, however, were inconclusive and it is believed the bicarbonate converted to carbon dioxide (CO2) and permeated through the sample bags. Today the crew collected new samples of the effluent from MF Beds 1 and 2 using ITCS sample bags that will not allow for CO2 permeation. These samples will be returned for analysis. The crew also replaced the WPA Separator Filter located on the Mostly Liquid Separator (MLS) and replaced a Waste Water Filter.

Москва. 24 апреля. INTERFAX.RU - На российском сегменте Международной космической станции (МКС) возникли проблемы с качеством горячей воды, космонавты вынуждены потреблять воду на американском сегменте, сообщил "Интерфаксу" информированный источник.

"В горячей воде на российском сегменте МКС обнаружена примесь желтого цвета неизвестного происхождения. Поэтому при необходимости российские космонавты получили рекомендацию использовать воду для питья из запасов американского сегмента, для технических нужд - получаемую путем регенерации", - сказал источник.

Предварительно, причиной неполадки стало загрязнение воды в баках космического "Грузовика" "Прогресс МС-07", либо неисправность водонагревателя на российском сегменте.

Американские астронавты используют на МКС систему регенерации воды из мочевины. Аналогичную систему в экспериментальном режиме на российском модуле "Рассвет" монтируют в настоящее время российские космонавты. Ранее подобная система использовалась на российской орбитальной станции "Мир".

Штатной системой укомплектован многофункциональный лабораторный модуль "Наука", который планируется запустить к МКС в 2019 году. В дальнейшем модификация такой системы может применяться при пилотируемой миссии к Луне для создания Лунной станции в рамках проекта Deep Space Gateway.

"Корабль сможет взять на борт лишь ограниченные запасы питьевой воды, потребность в ней, однако, будет велика. Такая система позволит удовлетворить ее в значительной степени", - сказал источник.

По словам собеседника агентства, российские космонавты на МКС до сих пор не занимались восстановлением питьевой воды из мочи. Такие отходы покидают российский сегмент на космических "грузовиках" "Прогресс", которые частично сгорают в плотных слоях атмосферы, не сгоревшие части затапливаются на "кладбище космических кораблей" в Тихом океане.

МОСКВА, 24 апр — РИА Новости. На российском сегменте (РС) Международной космической станции (МКС) заменят блок подогрева воды, который космонавты называют самоваром, сообщил РИА Новости во вторник руководитель полета РС МКС Владимир Соловьев.

Ранее в отечественных СМИ появились сообщения, что российские космонавты вынуждены пользоваться водой с американского сегмента станции из-за появления в воде на российском сегменте желтой примеси.

"Причина появления в воде примеси желтого цвета бытовая: в блоке подогрева воды, который выработал свой ресурс, появилась обычная накипь. В этом нет ничего страшного, с таким явлением мы регулярно сталкиваемся и на Земле. И проблема эта решается очень легко: мы просто оперативно поменяем на резервный этот блок, который космонавты обычно называют самоваром", — сказал Соловьев

При этом, по его словам, в программе полетов прописано, что во время штатной замены оборудования как на российском, так и американском сегменте пользоваться ресурсами своих соседей "абсолютно нормально". "У единого экипажа МКС – единая среда обитания", — добавил руководитель полета.

Astronauts Switch Roles Today from Scientists to Plumbers

Mark Garcia
Posted Apr 24, 2018 at 2:00 pm


NASA astronaut Drew Feustel conducts science operations using the Multi-Use Variable-G Platform that enables research into smaller and microscopic organisms.

The six Expedition 55 crew members are not only space scientists but also space plumbers who periodically work on the International Space Station's toilet. Aside from today's science and bathroom work, the crew also installed computer networking gear and inspected spacewalk equipment.

Спойлер

Drew Feustel, who began his career as an auto mechanic, studied to become a geophysicist and finally trained as a NASA astronaut, became a space plumber this morning. U.S. Navy Captain Scott Tingle of NASA brought Feustel up to speed on maintenance operations inside the bathroom, also known as the Waste and Hygiene Compartment, before updating its software and firmware.

NASA astronaut Ricky Arnold, who is on his second space mission, first as a space shuttle mission specialist and now as a station flight engineer, replaced a failed device inside the Human Research Facility-2 (HRF-2) today. The spare Rack Interface Controller controls various systems inside the HRF-2 which evaluates the physiological, behavioral, and chemical changes that take place in humans living in space.

Next, Feustel moved on to the Protein Crystal Growth-9 experiment with assistance from Japanese astronaut Norishige Kanai. The duo photographed and videotaped crystal samples grown for the middle and high school student-based research.

Feustel wrapped up his day installing firewalls, power supplies and cables providing additional computer security aboard the orbital lab. Kanai inspected spacewalk tethers and tools for damage before wearing an arm monitor that will analyze how microgravity has altered his circadian rhythms.

Human Research Facility-2 (HRF-2) B-Rack Interface Controller Install:

Спойлер

Today the crew installed the new BRIC into the HRF-2 rack to resolve Rack Interface Controller (RIC) issues that started back on March 25th. Following the installation, the ground attempted activation but was not able to establish communication with the High Rate Link Card (HRLC) within the BRIC. A power cycle of the rack and a restart of the bootloader were performed in an attempt to establish communication with the HRLC card, but were unsuccessful. The crew reconnected the HRF1 and HRF2 Portable Computers (PC)s back into the previous configuration to aid in further troubleshooting. Two subsequent reboots of the RIC bootloader recovered the HRLC, and HRF has been recovered to a normal state and software loads are in process. The next planned operations for the HRF2 rack are on May 14th.

Center for the Advancement of Science in Space (CASIS) Protein Crystal Growth (PCG)-9:

Спойлер

The crew removed PCG-9 sample bags containing Copper Sulfate from a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) and checked them for crystal growth. Since one of the bags contained no crystal growth the crew reprocessed that bag and returned all of the sample bags to the MELFI for additional growth time. These were the same sample bags that previously had shown no observed crystal growth. If crystals are observed today in the sample bags, they will be photographed and water extracted prior to the samples being returned to the MELFI. The Wisconsin Crystal Growing Contest-Wisconsin Space Crystal Mission (CASIS PCG 9) investigation provides student researchers the opportunity to explore crystal growth in the microgravity environment of the ISS. Crystals grown without the influence of gravity have shown to contain fewer imperfections and grow to larger sizes. Middle and high school students compete to grow the most perfect ground-based crystal, as judged by experts in the crystallography field. The students who present the crystals with the fewest imperfections have the opportunity to fly their experiments to the space station.

Today, a crewmember began a Circadian Rhythms experiment session by configuring the armband monitor and donning the watch and Thermolab double sensors, which will be worn for the next 36 hours. The objective of the experiment is to get a better understanding of any alterations in circadian rhythms in humans during long-term space flights. Such knowledge will not only provide important insights into the adaptations of the human autonomic nervous system in space over time, but also has significant practical implications by helping to improve physical exercise, rest- and work shifts as well as fostering adequate workplace illumination in the sense of occupational healthcare in future space missions.

Posted Apr 25, 2018 at 1:39 pm


Astronauts Scott Tingle (left) and Ricky Arnold wrap up spacesuit work following a successful spacewalk on March 29, 2018. The duo scrubbed cooling loops, performed the iodination of ion filters and tested the water conductivity inside a pair of U.S. spacesuits.

The Expedition 55 crew is experimenting with space gardening today while packing research samples and cargo for return to Earth. The space residents are also breaking down gear brought in from last month's spacewalk and getting ready for the next spacewalk.

Спойлер

Botany research aboard the International Space Station helps scientists and astronauts learn how to grow food off Earth to sustain future missions. Today's space gardening work performed by Flight Engineer Drew Feustelwill test the automated nourishment of lettuce and mizuna greens grown in the Veggie facility. The plants will be harvested and samples sent back to Earth for analysis.

Botanical samples are just one example of the multiple types of research and cargo that is sent to Earth packed inside the SpaceX Dragon cargo craft. Radiation monitors that recorded exposure levels in the station's crew quarters were collected by Japanese astronaut Norishige Kanai today for stowage inside Dragon. Engineers on the ground will examine the radiation data and determine the exposure risk to the crew and develop countermeasures.

NASA astronauts Scott Tingle and Ricky Arnold disassembled an external television camera group (ETVCG) brought in from last month's spacewalk. Tingle then replaced a failed light bulb in a light to be used on another ETVCG which will be installed on the next spacewalk scheduled for mid-May. Parts from the old ETVCG will be shipped back to Earth in Dragon for refurbishment.

Dragon is due for two more work days of packing before its return to Earth next week. Ground controllers will remotely detach Dragon from the Harmony module before releasing it from the grips of Canadarm2 into space at 10:22 a.m. EDT Wednesday, May 2. Tingle will monitor the robotics activities as NASA TV broadcasts the departure activities live starting at 10 a.m. Splashdown in the Pacific Ocean is planned for 4:02 p.m. and will not be seen on NASA TV.

After delivering more than 5,800 pounds of science investigations and cargo for NASA, a SpaceX Dragon cargo spacecraft is set to depart the International Space Station on Wednesday, May 2. NASA Television and the agency's website will provide live coverage of Dragon's departure beginning at 10 a.m. EDT.

Flight controllers on Earth will use the Canadarm2 robotic arm to detach the Dragon capsule, which arrived April 4, from the Earth-facing side of the station's Harmony module. After maneuvering Dragon into place, they will give the command to release the spacecraft as Expedition 55 Flight Engineer Scott Tingle of NASA monitors its departure at 10:22 a.m.

Dragon's thrusters will be fired to move the spacecraft a safe distance from the station before SpaceX flight controllers in Hawthorne, California, command its deorbit burn. The capsule will splash down about 4:02 p.m. in the Pacific Ocean, wh ere recovery forces will retrieve the capsule and more than 4,000 pounds of cargo, including science samples from human and animal research, biology and biotechnology studies, physical science investigations and education activities. The deorbit burn and splashdown will not be broadcast on NASA TV.

NASA and the Center for the Advancement of Science in Space (CASIS), the nonprofit organization that manages research conducted aboard the station's U.S. National Laboratory, will receive time-sensitive samples and begin working with researchers to process and distribute them within 48 hours of splashdown. In the event of adverse weather conditions in the splashdown zone in the Pacific, the departure and splashdown will occur on the backup date of May 5.

Dragon is the only space station resupply spacecraft able to return to Earth intact. SpaceX launched its 14th NASA-contracted commercial resupply mission to the station April 2 on a previously flown Falcon 9 rocket from Space Launch Complex 40 from Cape Canaveral Air Force Station in Florida.

#Саратов и #Энгельс - эти города очень важны для космонавтики. Юрий Гагарин учился в Саратовском техникуме, именно здесь поступил в аэроклуб и навсегда связал свою жизнь с авиацией. А недалеко от Энгельса находится место, где Юрий Алексеевич приземлился после легендарного полета.

ISS Daily Summary Report – 4/25/2018

Integrated Communications Unit (ICU) R4 Transition:

Спойлер

Yesterday, a software patch was loaded for the Ku-Band Command and Data Processer (KCDP) to correct the anomaly experienced where large packets of data were disrupting Ku Band forward data flow. After the load was complete, ground teams transitioned from KU Comm Unit (KCU)1 to KCU2, which contains the new R4 software, without issue. Two sporadic events were noticed, however, shortly after the transition: Intermittent Ku Forward Link Dropouts and KU Return power fluctuations impacted all Ku return end items. Engineering is monitoring the data as we continue to operate on KCU2. Ultimately, ICU R4 is expected to double the return link rate and storage record and playback rates from 256 Mbps to 517 Mbps.

Veggie Passive Orbital Nutrient Delivery System (PONDS):

Спойлер

The crew installed the Veggie PONDS experiment hardware and then initiated the experiment. Organisms grow differently in space, from single-celled bacteria to plants and humans. Future long-duration space missions will require crew members to grow their own food. Understanding how plants respond to microgravity and demonstrating the reliable vegetable production on orbit are important steps toward that goal. Veggie PONDS uses a newly developed passive nutrient delivery system and the Veggie plant growth facility aboard the ISS to cultivate lettuce and mizuna greens which are to be harvested on-orbit, and consumed, with samples returned to Earth for analysis.

Miniature Exercise Device (MED-2):

Спойлер

The crew set up cameras in Node 3 and the Cupola to capture video from multiple views of the Advanced Resistive Exercise Device (ARED). They applied body markers, performed exercises and then transferred the video for downlink. The ISS's exercise equipment is large and bulky, while the MED-2 aims to demonstrate small robotic actuators can provide motion and resistance for crew workout sessions, reducing the size and weight of exercise equipment for long-duration space missions. The MED-2 technology is critical for the design and development of second and third generation countermeasure hardware that is an order of magnitude lighter and smaller than existing ISS countermeasure hardware and that has significantly greater reliability.

Mouse Stress Defense:

Спойлер

The crew provided water to the Mouse Habitat Cage Units and checked their water nozzles today. Microgravity provokes cellular mechanical stresses and perturbs cellular signaling, leading to reduction of muscle and bone density. To overcome these stresses, one of the promising strategies is to activate Nrf2, a master regulator of antioxidant pathway. Mouse Stress Defense investigates how Nrf2 contributes to effective prevention of space-originated stresses.

Radiation Area Monitoring (RAM) retrieve:

Спойлер

The crew retrieved a total of 68 Radiation Area Monitors from all four Crew Quarters for return on SpX-14. Radiation exposure levels in the four Node 2 Crew Quarters (CQs) significantly differ between the highest and lowest as measured by the passive Radiation Area Monitors (RAMs). Measurements using active instruments reflects the differences in CQ radiation levels. It is well understood that these differences arise from a non-isotropic trapped radiation source, coupled with irregular shield factors. In the past there has been only one RAM located in each CQ, so as part of a CQ radiation assessment it was necessary to deploy several more RAMs inside each CQ to gather more data on radiation levels. Ground specialist hope to improve risk and exposure management based on the data from this assessment.

External TV Camera Group (ETVCG) Disassembly and Bulb R&R:

Спойлер

This morning the crew disassembled the ETCVG that was R&R'd on the Node 3 External Wireless Communication (EWC) US Extra-vehicular Activity (EVA). The purpose of this disassembly was to remove the Video Camera Luminare (VCL) with limited life remaining, and replace with a new VCL for future use. The disassembly proceeded nominally, but issues arose when testing the E2 (secondary) location, which is the backup light, on the ETVCG. During checkout of the secondary blub, there was a fault experienced that caused the upstream Utility Outlet Panel (UOP)'s relay to open. To determine if the bulb was the cause, the old VCL with limited life located in E1 (primary) was placed in the E2 location, and a new bulb installed in E1. The E1 bulb successfully illuminated and is considered operational.

Dragon Cargo Operations:

Спойлер

Today the crew continued with loading Dragon cargo scheduled for return. The crew worked via the third Dragon Cargo Message, uploaded yesterday evening; ground specialists estimate 10h 30m of cargo operations remain. SpaceX-14 is currently scheduled to unberth on 2 May at 9:32 AM CDT.

Extravehicular Activity (EVA) Preparation:

Спойлер

Today the crew set up the Enhanced Caution and Warning System (ECWS) Onboard Trainer to review operations of the EMU (ECWS) and practice EVA Cuff Checklist procedures. This task was the start of EVA preparation for US EVA 50, currently planned on May 16.

Мне удалось наконец-то сфотографировать Международный детский центр «Артек» с борта МКС. В детстве была мечта побывать в Артеке, но приехал я туда впервые уже будучи космонавтом. Это сказочное место... Каждый ребенок должен побывать в @artekrussia!

Astronauts Explore Life Science and Prepare for Spacewalk

Posted Apr 26, 2018 at 3:36 pm


NASA astronaut Scott Tingle prepares video equipment for a series of education videos being recorded for the STEMonstration campaign which demonstrates scientific concepts in space for students and teachers.

A wide variety of life science is being explored today aboard the International Space Station as Expedition 55 crew members prepare for a spacewalk planned for next month. The space residents also continued the upkeep of the orbital lab while robotics controllers set up an external experiment.

Japanese astronaut Norishige Kanai split his time today between tending mice and removing sensors attached to his arm. The rodents are being observed to detect the chemical signals that lead to muscle and bone loss in space and to provide therapies to keep astronauts healthy. Kanai also removed an armband monitor and sensors he wore for 36 hours that recorded alterations in his circadian rhythm caused by living in space.

Flight Engineers Ricky Arnold and Drew Feustel are getting ready for a May 16 spacewalk to swap out thermal control gear that circulates ammonia to keep station systems cool. The duo readied their spacewalk tools today then dumped water and purged gases from a pair of U.S. spacesuits.

Scott Tingle of NASA worked inside the Harmony module today to replace a deteriorating Pump Package Assembly (PPA) with a spare device. The PPA is a thermal control system that provides water cooling to station payloads and critical systems avionics.

Science is also taking place outside the space station and robotics controllers are working to transfer a tray for the materials exposure experiment (MISSE-FF) outside of the Kibo lab module through the lab's airlock for reconfiguration tomorrow. The complex robotic maneuvers are remotely controlled from the ground and use not only the Canadarm2 robotic arm but also the fine-tuning robotic hand known as Dextre. MISSE-FF will test materials, coatings, and components in the harsh environment of space.

Also, overnight, Russian flight controllers sent commands to deorbit the unpiloted ISS Progress 68 cargo craft that had been orbiting for the past month for engineering test following its undocking from the station March 28. It burned up harmlessly in the Earth's atmosphere over the southern Pacific.
