Концентрация токсичного бензола в атмосфере МКС не угрожает экипажу
03:16 14.08.2020

МОСКВА, 14 авг - РИА Новости. Новый прибор, привезенный в конце июля российским грузовым кораблем "Прогресс", показал, что концентрация токсичного бензола в атмосфере Международной космической станции находится в норме, сообщил РИА Новости представитель пресс-службы "Роскосмоса".

"Новый газоанализатор, доставленный на станцию транспортным грузовым кораблем "Прогресс МС-15", показал, что уровень концентрации бензола на МКС находится в норме", - сказал собеседник агентства.

Бензол был зафиксирован в воздухе МКС в апреле. Сначала его концентрация держалась на уровне 65 микрограммов на кубический метр, после чего стала повышаться. Однако, как сообщили в мае РИА Новости в "Роскосмосе", концентрация не превышала предельно допустимую норму и не угрожала экипажу. Источник бензола до сих пор не найден. Для снижения его концентрации экипаж установил угольные фильтры.

 Скрытый текст:

В июне единственный прибор для поиска источника бензола - американский анализатор качества воздуха AQM-1 - сломался при замерах в российском сегменте станции. На корабле "Прогресс МС-15", прибывшем на станцию 23 июля, были доставлены два американских газоанализатора Draeger и 90 тест-пластинок для поиска источника бензола. Как позже сообщило НАСА, приборы не нашли бензол в атмосфере МКС.

Бензол - бесцветная жидкость со специфическим сладковатым запахом. Входит в состав бензина и используется для производства лекарств, пластмасс, синтетической резины и красителей. Токсичен и канцерогенен.

Eleven years after the launch of the first H-II Transfer cargo vehicle (HTV) to the International Space Station, the Japan Aerospace Exploration Agency's (JAXA's) HTV-9 will depart the orbital laboratory Tuesday, Aug. 18, with live coverage beginning at 1:15 p.m. EDT on NASA Television and the agency's website.

Expedition 63 Commander Chris Cassidy of NASA will use the Canadarm2 robotic arm to release the spacecraft from the station at 1:35 p.m., ending its three-month stay. To prepare for release, flight controllers operating from NASA's Mission Control Center at the agency's Johnson Space Center in Houston will send commands to unbolt and detach the uncrewed cargo craft from the station's Harmony module and remotely operate Canadarm2 to move it into place for departure.

This will be the final station departure of JAXA's Kounotori, or "white stork," model cargo craft, nine of which have delivered more than 40 tons of supplies to space station crews. JAXA is developing a new fleet of HTV cargo craft, the HTV-X, which is targeted for its first launch in 2022.

The spacecraft, which launched from the Tanegashima Space Center in Japan on May 20, delivered about four tons of supplies and experiments to the orbital complex, including new lithium-ion batteries that were used to upgrade the station's power systems. The new-technology batteries were installed through a series of spacewalks along the far port truss "backbone" of the station.

HTV-9 will be commanded by JAXA flight controllers at its HTV control center in Tsukuba, Japan, to move away from the station and, on Aug. 20, to fire its deorbit engine in a burn that will send it back into Earth's atmosphere. Loaded with trash from the space station, the spacecraft will burn up harmlessly over the Pacific Ocean.

For nearly 20 years, astronauts have continuously lived and work on the space station, testing technologies, performing science and developing the skills needed to explore farther from Earth. As a global endeavor, 240 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 3,000 research and educational investigations from researchers in 108 countries and areas.

Through NASA's Artemis program, the agency will send astronauts to the Moon by 2024, with eventual human exploration of Mars. Inspiring the next generation of explorers - the Artemis Generation - ensures America will continue to lead in space exploration and discovery.

ISS Daily Summary Report - 8/12/2020

Space Studio KIBO:

 Скрытый текст:

The crew performed the KIBO studio setup with the X305 camera setup and recorded a live stream session for a JAXA TV show. The Space Frontier Studio KIBO is a broadcasting studio that is constructed and operated in the Japanese Experiment Module (JEM), also known as Kibo. The studio can livestream activities, interactive entertainment, and communication from space. The program can receive uplinked video and audio from a ground studio to Space Frontier Studio KIBO, and downlink video and audio from space to ground.

Packed Bed Reactor Experiment-2 (PBRE-2):

 Скрытый текст:

The crew performed PBRE-2 hardware setup and connected the cables and hoses in the Micro Gravity Science Glovebox (MSG). The ground will then initiate a run for several months using 2 science modules. The PBRE-2 investigates the forces acting on and created by a gas and a liquid flowing simultaneously through a column filled with glass spheres in microgravity. Known as two-phase flow, this side-by-side movement of a gas and liquid is used in a variety of space-based systems and equipment. Results could help improve the design of future mass and heat transfer equipment used in space.

H-II Transfer Vehicle (HTV)9 Cargo Operations:

 Скрытый текст:

In preparation for HTV9 unberth, scheduled for August 18th, the ISS crew continued to pack the HTV vehicle with Cargo Transfer Bags (CTBs). The crew also received Russian items for disposal. Ground teams estimate approximately 2 hours remain to complete available cargo ops. The crew will continue to focus on cargo operations in preparation for HTV9 close out and departure early next week.

Astrobee:

 Скрытый текст:

The crew powered up the Astrobee free flyers and cleared away and stowed items within the JEM module in preparation for Astrobee flyer operations. Astrobee is made up of three free-flying, cube-shaped robots which are designed to help scientists and engineers develop and test technologies for use in microgravity to assist astronauts with routine chores, and give ground controllers additional eyes and ears on the space station. The autonomous robots, powered by fans and vision-based navigation, perform crew monitoring, sampling, logistics management, and accommodate up to three investigations.

Electro-static Levitation Furnace (ELF):

 Скрытый текст:

The crew installed the Round Robin #2 Sample Cartridge into the ELF facility. The MSPR work bench was then closed out. ELF is an experimental facility designed to levitate, melt and solidify materials by containerless processing techniques using the electrostatic levitation method.  With this facility thermophysical properties of high temperature melts can be measured and solidification from deeply undercooled melts can be achieved.

JEM Water Recovery System (JWRS):

 Скрытый текст:

The crew performed cable connections to hoses and bags as part of closeout procedures. The demonstration of JEM Water Recovery System (JWRS) generates potable water from urine. In the past on manned spacecraft, urine and waste water were collected and stored, or vented overboard. For long-term space missions, however, water supply could become a limiting factor. Demonstrating the function of this water recovery system on orbit contributes to updating the Environmental Control and Life Support System (ECLSS) to support astronauts on the space station and future exploration missions.

In-Flight Maintenance (IFM) Node 2 Intermodule Ventilation (IMV) Screen Installation:

 Скрытый текст:

Today, the crew installed an IMV screen over the Node 2 Starboard Forward IMV Inlet. The fine mesh screen was installed to decrease foreign object debris (FOD) in the Columbus module and ventilation hardware. The original mesh size of the current screen was fine enough to catch larger particles but over time smaller debris can pass through the screen and collect in the ducting downstream of the IMV and cabin fans. Adding the finer mesh screen will protect the ventilation hardware from debris build up over time.

Emergency Communication Verification:

 Скрытый текст:

Today, the crew performed an emergency communication checkout from the US segment using the Very High Frequency (VHF)-1 comm system over US ground sites. During the Wallops ground site pass, the crew conducted a comm check with each center in Houston, Huntsville, Munich, Tsukuba, and Moscow. VHF-1 provides the emergency back-up for ISS to ground communication. Due to the rarity of using the VHF system over the US ground sites, emergency VHF comm verifications offer the only means of assuring the end-to-end VHF systems, equipment and personnel are operational and ready to support an emergency.

H-II Transfer Vehicle (HTV)9 Cargo Operations:

 Скрытый текст:

Today, the crew continued with HTV9 cargo transfer operations. Ground teams estimate approximately 2 hours remain to complete available cargo ops. The crew will continue to focus on HTV9 cargo operations in preparation for HTV9 close out and departure early next week. HTV9 is scheduled to unberth from the ISS on Tuesday, August 18th.

Posted Aug 14, 2020 at 1:41 pm


The SpaceX Crew Dragon and the Japan's HTV-9 resupply ship figure prominently in this photograph taken during the July 1 spacewalk.

Canada's versatile robotic arm, the 57.7-foot-long Canadarm2, is in place and ready to grapple and release Japan's resupply ship from the International Space Station next week. The Expedition 63 crew is continuing to pack the cargo craft while training for its robotic release.

Commander Chris Cassidy of NASA will command the Canadarm2 to release the H-II Transfer Vehicle-9 (HTV-9) on Tuesday at 1:35 p.m. EDT. Roscosmos cosmonaut and Flight Engineer Ivan Vagner will support Cassidy at the robotics workstation in the station's "window to the world," the cupola.

Both crewmates will be practicing the robotic maneuvers on a computer Friday and Monday to prepare for the HTV-9's release. Cassidy continues to pack the HTV-9 with discarded gear and will close the hatch to the Japanese resupply ship on Monday. NASA TV will begin its live coverage of the release activities on Tuesday at 1:15 p.m.

Space traffic will pick up again in October with a U.S. cargo ship slated to arrive and a crew exchange planned at the orbiting lab. Northrop Grumman is targeting early October for the rendezvous and robotic capture of its Cygnus cargo craft at the station.

On Oct. 14, three Expedition 64 crew members will launch aboard the Soyuz MS-17 crew ship toward the orbital lab. NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov will take a six-hour ride that day and dock to the Rassvet module beginning a six-month station mission.

One week later, Cassidy will end his mission along with Expedition 63 crewmates Vagner and Russian Flight Engineer Anatoly Ivanishin. The trio will undock from the Poisk module in the Soyuz MS-16 crew ship on Oct. 21 and parachute to a landing in Kazakhstan ending a 195-day research mission aboard the station.

NASA and SpaceX are targeting no earlier than Oct. 23 for the first operational flight with astronauts of the Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as a part of the agency's Commercial Crew Program. NASA's SpaceX Crew-1 mission will be the first of regular rotational missions to the space station following completion of NASA certification.

The mission will carry Crew Dragon commander Michael Hopkins, pilot Victor Glover, and mission specialist Shannon Walker, all of NASA, along with Japan Aerospace Exploration Agency (JAXA) mission specialist Soichi Noguchi for a six-month science mission aboard the orbiting laboratory following launch from Launch Complex 39A at NASA's Kennedy Space Center in Florida.

Crew-1 will launch in late October to accommodate spacecraft traffic for the upcoming Soyuz crew rotation and best meet the needs of the International Space Station. Launch will follow the arrival of NASA astronaut Kate Rubins and cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov of the Russian space agency Roscosmos aboard their Soyuz MS-17 spacecraft and the departure of NASA astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner from the space station. The launch timeframe also allows for a crew handover with NASA's SpaceX Crew-2 mission next spring.

The Crew-1 mission is pending completion of data reviews and certification following NASA's SpaceX Demo-2 test flight, which successfully launched NASA astronauts Robert Behnken and Douglas Hurley to the International Space Station on May 30 and returned them safely home with a splashdown off the Florida coast in the Gulf of Mexico on Aug. 2. Demo-2 was the first crewed flight test of a commercially-owned and operated human space system.

NASA certification of SpaceX's crew transportation system allows the agency to regularly fly astronauts to the space station, ending sole reliance on Russia for space station access.

For almost 20 years, humans have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration to the Moon and Mars.

NASA is enabling economic growth in low-Earth orbit to open access to space to more people, more science, and more companies than ever before.

NASA планирует запуск пилотируемого корабля Crew Dragon к МКС не ранее 23 октября

НЬЮ-ЙОРК, 14 августа. /ТАСС/. Национальное управление США по аэронавтике и исследованию космического пространства (NASA) планирует следующий запуск пилотируемого космического корабля Crew Dragon компании SpaceX к Международной космической станции (МКС) не ранее 23 октября. Об этом говорится в сообщении, размещенном в пятницу на сайте космического ведомства США.

"NASA и SpaceX намечают не ранее 23 октября первый штатный полет астронавтов на Crew Dragon к МКС в рамках коммерческой программы пилотируемых Crew", - уточнило NASA. Это будет "первая регулярная экспедиция на космическую станцию, осуществляемая по ротационному принципу".

В состав экипажа корабля включены американцы Майкл Хопкинс, Виктор Гловер и Шэннон Уокер, а также астронавт Японского агентство аэрокосмических исследований (JAXA) Соити Ногути. Им предстоит провести на борту МКС шесть месяцев. Пуск ракеты-носителя Falcon 9 состоится с космодрома на мысе Канаверал (штат Флорида).

 Скрытый текст:

Перед этим на орбитальный комплекс планируется отправить космонавтов Роскосмоса Сергея Рыжикова, Сергея Кудь-Сверчкова и астронавта NASA Кэтлин Рубинс. Эта экспедиция стартует на борту корабля "Союз МС-17".

Первый пилотируемый полет на Crew Dragon на орбиту совершили в этом году астронавты Даглас Хёрли и Роберт Бенкен. Корабль, выведенный на орбиту 30 мая, пристыковался в автоматическом режиме к МКС 31 мая. Он представляет собой модификацию грузового корабля Dragon, который регулярно доставляет туда грузы. Хёрли и Бенкен присвоили ему название Endeavour по аналогии с кораблем программы Space Shuttle, на котором оба астронавта выполняли свои первые космические полеты.

Запуск Crew Dragon стал первым за девять лет пилотируемым полетом, осуществляемым с территории США на космическом корабле местного производства. NASA прекратило их в 2011 году. С тех пор астронавты доставлялись на МКС российскими "Союзами".

Last in current line of Japan's HTV cargo ships ready to depart space station

August 18, 2020 | Stephen Clark

The last of Japan's first series of HTV supply ships will leave the International Space Station on Tuesday with several tons of trash, old batteries, and unneeded equipment, heading for a destructive re-entry before the debut of an upgraded cargo freighter design.

The HTV cargo ship will be released from the space station's Canadian-built robotic arm at 12:35 p.m. EDT (1635 GMT) to wrap up an 85-day stay at the orbiting research outpost.

Astronauts closed the hatches between the HTV and the station's Harmony module Monday in preparation for the spacecraft's departure. Ground teams then planned to use the robotic arm to detach the HTV from its space station berthing port and maneuver it to a location roughly 30 feet, or 9 meters, below the complex.

Space station commander Chris Cassidy will send the command for the robotic arm to release the HTV Tuesday. Russian cosmonaut Ivan Vagner will assist Cassidy at a robotics work station in the space station's windowed cupola module.

The HTV will fire thrusters to depart the vicinity of the space station, then perform burns to re-enter the atmosphere around 3:07 a.m. EDT (0707 GMT) Thursday. Serving as a trash disposal vehicle, the spacecraft will burn up on re-entry targeted to occur over the South Pacific Ocean.

Japan's ninth HTV supply carrier arrived at the station May 25, five days after launch from the Tanegashima Space Center aboard a Japanese H-2B rocket. The HTV 9 mission delivered more than 13,600 pounds, or 6.2 metric tons, of cargo, supplies and experiments in its pressurized module and on its external payload bay, according to the Japan Aerospace Exploration Agency.

The barrel-shaped H-2 Transfer Vehicle is nicknamed Kounotori, which is Japanese for "white stork," and stretches around 33 feet (10 meters) long and 14 feet (4.4 meters) wide.

The HTV 9 mission carried six new lithium-ion batteries to the station inside its unpressurized cargo compartment. NASA astronauts Chris Cassidy and Bob Behnken installed the upgraded batteries on the space station's solar power truss, completing a multi-year upgrade to the research lab's electrical system.

A cargo pallet loaded with eight obsolete nickel-hydrogen batteries was robotically installed into the HTV 9 spacecraft for disposal. Astronauts also placed a no-longer-needed resupply rack and a European stowage rack into the HTV ahead of its departure from the space station Tuesday.

The last set of disused nickel-hydrogen batteries will be jettisoned from the space station by its robotic arm later this year to naturally fall out of orbit due to aerodynamic drag.

The HTV 9 mission marks the final flight of Japan's current HTV spacecraft design, which first reached the space station in 2009. The Japan Aerospace Exploration Agency is developing an upgraded cargo vehicle named the HTV-X, which is slated to fly to the space station for the first time in 2022.

Unlike the HTV, which is grappled by the robotic arm and berthed with the space station, Japan's HTV-X is designed to directly dock with the orbiting outpost, using the same docking ports as SpaceX's Crew Dragon and Boeing's Starliner crew capsules.

JAXA provides resupply services to the space station to help pay for Japan's share of the the research lab's operating costs. In addition to space station missions in low Earth orbit, Japanese officials say the HTV-X spacecraft could haul logistics to the future Gateway mini-space station near the moon.

Japan's H-2B launcher is also being retired with the final HTV flight. The HTV-X missions will launch on Japan's next-generation H3 rocket.

Other equipment delivered to the station in May by Japan's HTV 9 mission included a module to support a Japanese combustion experiment, a camera from a Spanish company that will be tested to gauge its usefulness on small satellites and CubeSats, new science racks for to the space station NASA and the European Space Agency, plus a water tank and fresh food for the research lab's crew.

The final HTV (this version before HTV-X) is about to be released for the final time.
