СОЧИ, 21 июля. /ТАСС/. Президент России Владимир Путин посоветовал юным разработчикам наноспутника принять участие в конкурсе Роскосмоса для его запуска на орбиту. Свое предложение глава государства озвучил, когда познакомился с разработкой в ходе программы "Недетский разговор с Владимиром Путиным".

Модель спутника организаторы встречи внесли в зал в черном ящике. "У меня тоже есть черный чемоданчик", - пошутил Путин, а затем подошел поближе, чтобы разглядеть установку.

Спутник размером 10 на 10 см и весом всего порядка одного килограмма ребята разработали под руководством инженеров предприятия "НПО машиностроения". В рамках направления "Спутники и пилотируемая космонавтика" в ходе июльской смены в "Сириусе" юные конструкторы провели необходимые испытания своей установки. В дальнейшем им еще нужно будет создать математическую модель движения и реализовать алгоритм управления, который может быть реализован при запуске спутника в космос с борта Международной космической станции в конце 2017 - начале 2018 года.

"Здесь мы очень надеемся на Роскосмос, потому что в 2013 году он объявил, что будут производить запуск образовательных спутников бесплатно", - рассказал главе государства Александр Воронцов из Кочканара Свердловской области, отметив, что другого пути доставки их работы на орбиту нет.

"Давайте посмотрим, я тоже с Роскосмосом переговорю, - пообещал Путин. - Я так понимаю, что они по конкурсу это будут делать? Вам тоже нужно будет выиграть этот конкурс", - добавил президент.

A new International Space Station crew is less than a week away from beginning a 4-1/2 month mission living and working in space. The trio from the United States, Russia and Italy is in Kazakhstan counting down to a Friday launch at 11:41 a.m. EDT inside the Soyuz MS-05 spacecraft.

Cosmonaut Sergey Ryazanskiy will command the Soyuz vehicle during the six-hour, 19-minute ride from Earth to the station's Rassvet module. He will be flanked by crewmates Randy Bresnik of NASA and astronaut Paolo Nespoli from the European Space Agency. NASA TV will cover the launch and docking activities live.

Meanwhile, the Expedition 52 crew orbiting Earth now explored how microgravity impacts cancer therapies. The trio also worked on various maintenance tasks throughout the orbital lab.

New space research aboard the station is providing insights that may accelerate development of drugs that target only cancer cells. Flight Engineer Peggy Whitson peered at cells today through a microscope for the cancer study that started in April this year. Results may create more effective treatments for cancer patients on Earth.

Jack Fischer of NASA moved a variety of science gear around and cleaned a mouse habitat. He also swapped out a hard drive for an experiment that measures the composition of meteors orbiting and entering Earth's atmosphere.

Crew Tests Lower Body Suit to Protect Vision; Soyuz Rocket Rolls Out Wednesday
Posted on July 25, 2017 at 1:33 pm by Mark Garcia.


Astronaut Peggy Whitson looks at the Earth below from inside the seven-windowed cupola.

One of the effects of living in space is the tendency of fluids to shift upward towards an astronaut's head. This results in the common "puffy face" appearance astronauts experience when they escape Earth's gravity. However, the more serious effects observed on orbit could include eye and vision damage.

The three Expedition 52 crew members are exploring a unique device that reverses some of these headward fluid shifts and could counter changes to vision in space. Peggy Whitson of NASA tried on the Lower Body Negative Pressure suit today with assistance from Commander Fyodor Yurchikhin of Roscosmos. NASA astronaut Jack Fischer joined the commander and conducted brain/ear fluid pressure tests and eye exams on Whitson.

Back on Earth, three new Expedition 52-53 crew members will see their Soyuz MS-05 rocket roll out to its launch pad Wednesday. The trio from the United States, Russia and Italy will blast off inside the Soyuz rocket Friday at 11:41 a.m. EDT from the Baikonur Cosmodrome in Kazakhstan. Randy Bresnik of NASA, Sergey Ryazanskiy from Roscosmos and Paolo Nespoli from the European Space Agency will live on the orbital complex until mid-December.

Investigation Tests New Methods of Water Recycling in Space

Sometimes the best solution to a complex problem is the simplest one. That's the approach that the Capillary Structures for Exploration Life Support (Capillary Structures) team took when designing the fluid physics investigation aboard the International Space Station. The Capillary Structures investigation uses capillary action, or the ability for a liquid to flow through a narrow spaces, such as small tubes, to move liquids and gases in microgravity, a task that can't be tested in Earth's gravity environment.

Спойлер

NASA astronaut Jack Fischer works with the capillary sorbent hardware, that is made up of 3D printed contactors (center) with several capillary channels. The contactors, or capillary structures under investigation, are supported by tubing, valves, and a pump. This highly interactive experiment simulates the fluidics of a liquid sorbent system for the removal of CO2 from the air.

Life-support technology aboard any spacecraft is vitally important, especially as crews move farther away from Earth and into deep space. Many life support systems function differently in the space station's microgravity environment than they would on Earth, including the way that liquids collect on and move across surfaces.

Currently, the life-support systems aboard the space station require special equipment to separate liquids and gases. This technology utilizes rotating and moving parts that, if broken or otherwise compromised, could cause contamination and/or system failure. The Capillary Structures investigation studies a new method of water recycling and carbon dioxide removal using structures designed in specific shapes to manage fluid and gas mixtures in microgravity.

As opposed to the expensive, machine-based processes currently in use aboard the station, the Capillary Structures equipment is made up of small, 3-D printed geometric shapes of varying sizes that clip into place.

The impact of this research could benefit those on Earth as well. Research gathered during this investigation will teach us about using geometry to optimize evaporation, more efficient water recovery systems, passive purification methods, other water processing approaches on Earth.

The first of this two-part investigation focuses on evaporation, a process that is specifically influenced by gravity and one that isn't obvious in the microgravity environment of space.

"If you could do controllable evaporation in space, you could do all kinds of things" said Mark Weislogel, one of the project's principal investigators. "You could evaporate urine and recover all of the water. All of it. If you had a way of holding the liquid in a passive, no-moving-parts way like a puddle does on earth, but in space, then you could do a lot of unique processing, safely and with no maintenance."

Crew members will fill each structure as research teams on the ground observe the behavior of the liquids over a few days via time lapse photography. Results from the investigation could lead to the development of new processes that are simple, trustworthy, and highly reliable in the case of an electrical failure or other mechanical system malfunction.

"Were going to be getting detailed information about how the liquid evaporates out of the structures," said Kyle Viestenz, co-investigator for the project. "The structures are set up to have different geometries, different angles, different heights, all these different parameters that we are varying across these structures to get quantitative data of evaporation in low gravity."

The second part of the investigation demonstrates the use of fluids in a carbon dioxide removal system, called the Carbon Dioxide Liquid Sorbent System. This system uses a network of "water falls" to bring a liquid sorbent, or a material used to absorb gases, into contact with air, allowing the carbon dioxide to be carried away by the liquid. Of course, in a microgravity environment, the liquid does not "fall," but is driven by surface tension forces generated passively by the unique surface geometry of the capillary structures.

Also comprised of 3-D printed capillary structures, this portion of the investigation is optimized for liquids to flow through the structures, rather than to simply evaporate.

"One of the things needed to scrub the carbon dioxide out of the air would be to split the fluid into multiple channels to achieve high surface area for the reaction," said Viestenz. "In this investigation, we are going to be splitting the flow into multiple parallel open passages and recollecting them again--something that hasn't been done before and will go a long way in demonstrating this kind of technology. The results are broadly applicable to liquid fuels, propellants, and coolants as well as myriad passive water management operations for life support"

Galileo arrives on the Space Station


SCaN Testbed on Station

26 July 2017
If one's good, two are better, and this is especially true when it comes to developing new applications for navsat systems like Galileo and GPS. That's why an experiment on the International Space Station will start receiving signals from both simultaneously.

Satellites of America's GPS provide signals for navigation and timing services in an enormous variety of applications worldwide – on smartphones, in automobile navigation systems and in economically vital services like aviation, maritime traffic and banking.

Today, GPS is synonymous with satnav, but after years of development and regular launches, Europe's Galileo navigation system has come of age: its 18 satellites – soon to be 24 plus in-orbit spares – are now transmitting the highly accurate signals necessary to deliver navigation services across a wide range of activities.

Спойлер

"This means both European Galileo and American GPS signals can be received simultaneously, allowing us to investigate how the two sets of signals could be used together in a single device or application to provide mutually enhanced navigation," says Werner Enderle, Head of ESA's Navigation Support Office.


ISS - International Space Station

To achieve this two-for-one reception, a cutting-edge experiment conducted by ESA and NASA on the International Space Station will use special techniques to receive signals from both GPS and Galileo satellites.

"The aim is to generate data that can be used to demonstrate the value of a dual receiver compared to one that receives just GPS or Galileo alone," says Werner.

"In future, this could open the door to a large range of new applications featuring the space-based use of multiple navigation satellite system signals."

SCaNing for accuracy

Спойлер

The experiment got underway with initial testing last year using NASA's Space Communications and Navigation (SCaN) Testbed, an experimental software-configurable radio receiver that was installed on the Station in 2012.


Galileo satellite

The device's capability to receive both GPS and Galileo signals had already been proven in 2014, opening the door for the use of Galileo, which uses the same frequencies and is interoperable with GPS.

Now the in-orbit experiments will make it among the world's first space-validated, dual GPS-Galileo receivers.

This year, both agencies will continue developing the ground systems needed to support the experiment, and the main test phase is set to run from mid-2017 to the end of 2018.

"Dual Galileo–GPS signal reception in space allows us to study ways to enhance interoperability, while using the signals to achieve more precise and robust orbital predictions," says David Chelmins, SCaN Testbed project manager at NASA's Glenn Research Center, Cleveland, USA.

"This could lead to improved applications such as autonomous spacecraft operations and scientific measurements, and perhaps new scientific or commercial space applications no one's even thought of yet."

ESA teams take part

Спойлер

Navigation Support Facility

The Navigation Support Office, at ESA's mission control centre in Darmstadt, Germany, will provide processing and analysis expertise eventually to perform a precise orbit determination to pin down the trajectory of the SCaN Testbed receiver on the Station to within tens of centimetres.

The development of the software needed to track GPS and Galileo signals simultaneously for the SCaN Testbed has been led by experts on the Radio Navigation Systems and Technology team at the Agency's technical centre in the Netherlands.

This specialised software, developed in collaboration with Italian company Qascom, will convert the received Galileo and GPS signals into 'observables', numbers with a physical meaning from which the receiver position can be precisely calculated in space and on ground.

It is also planned that the software will generate realtime position solutions, demonstrating the ability of the Station to track its own orbit accurately and paving the way for new operational techniques.

[свернуть]

Supporting navigation

Спойлер

ESA experts are well used to conducting the type of ultraprecise analysis that the SCaN experiment will require.

The Navigation Support Office routinely provides highly accurate navigation and satellite geodesy services to customers worldwide. It receives data from a wide variety of sources and then calculates and predicts highly accurate orbits, timing corrections and related products for satellites that are part of global navigation systems, like GPS, Galileo, Glonass and BeiDou.

These are used to improve global navigation satellite position accuracy, enabling even more sophisticated applications supporting scientific studies, large-scale climate monitoring, and tracking of long-term changes in Earth's geology.
