At 5:28 a.m. EST, Expedition 57 Flight Engineer Serena Auñón-Chancellor of NASA used the International Space Station's robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as Alexander Gerst of ESA (European Space Agency), monitored Cygnus' systems during its approach. Next, ground controllers will command the station's arm to rotate and install Cygnus, dubbed the SS John Young, on the bottom of the station's Unity module.

NASA Television coverage of installation will begin at 6:45 a.m., and installation of the Cygnus spacecraft to the space station is expected to be completed later this morning.

Canadian Robotic Arm Installs U.S. Cygnus Cargo Ship to Station

The Northrop Grumman Cygnus cargo ship was bolted into place on the International Space Station's Earth-facing port of the Unity module at 7:31 a.m. EST. The spacecraft will spend about three months attached to the space station before departing in February 2019. After it leaves the station, the uncrewed spacecraft will deploy several CubeSats before its fiery re-entry into Earth's atmosphere as it disposes of several tons of trash.

The spacecraft's arrival brings close to 7,400 pounds of research and supplies to space station. Highlights of NASA-sponsored research to advance exploration goals and enable future missions to the Moon and Mars include:

Sensory input in microgravity

Changes in sensory input in microgravity may be misinterpreted and cause a person to make errors in estimation of velocity, distance or orientation. VECTION examines this effect as well as whether people adapt to altered sensory input on long-duration missions and how that adaptation changes upon return to Earth. Using a virtual reality display, astronauts estimate the distance to an object, length of an object and orientation of their bodies in space. Tests are conducted before, during and after flight. The investigation is named for a visual illusion of self-movement, called vection, which occurs when an individual is still but sees the world moving past, according to principal investigator Laurence Harris. The Canadian Space Agency (CSA) sponsors the investigation.

Solidifying cement in space

The MVP-Cell 05 investigation uses a centrifuge to provide a variable gravity environment to study the complex process of cement solidification, a step toward eventually making and using concrete on extraterrestrial bodies. These tests are a follow-on to the previous studies known as Microgravity Investigation of Cement Solidification (MICS), which studied cement solidification in microgravity.  Together, these tests will help engineers better understand the microstructure and material properties of cement, leading to design of safer, lightweight space habitats and improving cement processing techniques on Earth. This investigation is sponsored by NASA.

Investigations sponsored by the U.S. National Laboratory on the space station, which Congress designated in 2005 to maximize its use for improving quality of life on Earth, include:

From stardust to solar systems

Much of the universe was created when dust from star-based processes clumped into intermediate-sized particles and eventually became planets, moons and other objects. Many questions remain as to just how this worked, though. The EXCISS investigation seeks answers by simulating the high-energy, low gravity conditions that were present during formation of the early solar system. Scientists plan to zap a specially formulated dust with an electrical current, then study the shape and texture of pellets formed.

Principal investigator Tamara Koch explains that the dust is made up of particles of forsterite (Mg2SiO4), the main mineral in many meteorites and related to olivine, also known as the gemstone peridot. The particles are about the diameter of a human hair.

Growing crystals to fight Parkinson's disease

The CASIS PCG-16 investigation grows large crystals of an important protein, Leucine-rich repeat kinase 2, or LRRK2, in microgravity for analysis back on Earth. This protein is implicated in development of Parkinson's disease, and improving our knowledge of its structure may help scientists better understand the pathology of the disease and develop therapies to treat it. Crystals of LRRK2 grown in gravity are too small and too compact to study, making microgravity an essential part of this research.

Better gas separation membranes

Membranes represent one of the most energy-efficient and cost-effective technologies for separating and removing carbon dioxide from waste gases, thereby reducing greenhouse gas emissions. CEMSICA tests membranes made from particles of calcium-silicate (C-S) with pores 100 nanometers or smaller. Producing these membranes in microgravity may resolve some of the challenges of their manufacture on Earth and lead to development of lower-cost, more durable membranes that use less energy. The technology ultimately may help reduce the harmful effects of CO2 emissions on the planet.

The star named ISS

International space station is the biggest object on orbit made by man. Station can be seen from Earth at night of clear skies. It looks like a star.

В "Роскосмосе" рассказали о планах поднять орбиту МКС на 15 километров
09:51 19.11.2018

МОСКВА, 19 ноя — РИА Новости. Среднюю высоту орбиты Международный космической станции планируется увеличить с нынешних 405 до 420 километров, чтобы компенсировать снижение высоты от грядущей солнечной активности, сообщается в материалах "Роскосмоса", распространенных на проходящей в Москве конференции, посвященной 20-летию МКС.

"В настоящее время мы разрабатываем план, чтобы поднять Международную космическую станцию на высоту 420 километров для подготовки к началу очередного цикла солнечной активности", — приводятся в материалах слова руководителя полета российского сегмента МКС, космонавта Владимира Соловьева.

Солнечная активность имеет цикл в 11 лет, когда чередуются периоды слабой и сильной активности. В 2008 году начался 24-й цикл солнечной активности. Солнечное излучение возбуждает ионы в ионосфере Земли, сама ионосфера становится шире и более плотной, что ведет к дополнительному трению об нее поверхности МКС, а следовательно и торможению станции.

До 2011 года, срока прекращения эксплуатации американских шаттлов, высота орбиты МКС составляла 330-350 километров. Это было обусловлено низкой грузоподъемностью шаттлов на более высокие орбиты.
