Ужос какой. А че так долго то? Что это за технологии такие, что надо полтора месяца надувать?

[silentpom]

да просто не надо особо

[Сеян]

Может быть хотят проверить как поведет себя материал стенок модуля после месяца в сложенном состоянии.

[Paleopulo]

Вроде хотели развернуть, когда Сигнус с Дрэгоном улетят, не?

The coming week is another big one for SpaceX, whose unmanned Dragon capsule is scheduled to depart the International Space Station and return to Earth on Wednesday morning.
The station's 58-foot robotic arm is expected to release the Dragon and its 3,700 pounds of cargo at 9:18 a.m., beginning a less than six-hour journey culminating in a Pacific Ocean splashdown under parachutes.
Because of a failed launch last summer, this Dragon will be the first to return science experiments and hardware from the ISS in a year. No other spacecraft flying today can bring large quantities of cargo back down to the ground.
Among this mission's precious cargo are biological samples collected during former NASA astronaut Scott Kelly's yearlong mission on the station that ended in March.
The Dragon is returning almost exactly one month after its April 10 arrival at the station, two days after launching from Cape Canaveral Air Force Station.
If splashdown conditions are unfavorable Wednesday, the Dragon's departure could be delayed a few days.

The SpaceX Dragon is being packed with critical science today and tomorrow before its release and splashdown on Wednesday. The crew is also reviewing Dragon departure procedures and training for its release from the grip of the Canadarm2 robotic arm.
Dragon is currently attached to the Harmony module. After it is uninstalled early Wednesday with the 57.7 foot Canadarm2, the Dragon will be released at 9:18 a.m. EDT for a splashdown in the Pacific Ocean at 2:55 p.m. NASA TV will broadcast the release and departure activities live, however the splashdown and recovery work will not be televised.
A pair of science freezers carrying experiment samples for analysis will be removed from the space station and returned to Earth inside Dragon. The commercial space freighter is returning a variety of science and gear for NASA.
The Russian cosmonauts are relaxing today in observance of Victory Day when Germany surrendered to the Soviet Union on May 9, 1945, ending World War II. The astronauts in the U.S. segment of the station continued science work, Dragon packing and robotics training for Wednesday's release activities.

Watch NASA TV for Live Coverage of Dragon Release
Posted on May 11, 2016 at 8:24 am by Mark Garcia.

The SpaceX Dragon cargo ship is seen arriving at the International Space Station April 10 before it is captured and installed to the Harmony module.
 
NASA Television will provide live coverage of the departure of the SpaceX Dragon spacecraft from the International Space Station beginning at 9 a.m. EDT. Dragon was detached from the Earth-facing side of the station's Harmony module earlier this morning. Robotics controllers will maneuver Dragon into place and Expedition 47 robotic arm operator Tim Peake of ESA (European Space Agency) will execute the command for its 9:18 a.m. release.
Dragon arrived at the space station April 10 after launching April 8 from Cape Canaveral Air Force Station in Florida carrying almost 7,000 pounds of supplies and cargo on the company's eighth commercial resupply mission to the station.
Release of the spacecraft by the station's robotic arm will begin the Dragon's return to Earth carrying more than 3,700 pounds of NASA cargo and science samples from human research, biology and biotechnology studies, physical science investigations and education activities sponsored by NASA and the Center for the Advancement of Science in Space, the nonprofit organization responsible for managing research aboard the U.S. national laboratory portion of the space station.
The capsule is currently scheduled to splashdown in the Pacific Ocean about 2:55 p.m., approximately 261 miles southwest of Long Beach, California.

Dragon Splashes Down Safely to Complete CRS-8                             
Posted on May 11, 2016 at 3:01 pm by Steven Siceloff.      
                                       

SpaceX's Dragon cargo craft splashed down in the Pacific Ocean at 2:51 p.m. EDT, about 261 miles southwest of Long Beach, California, marking the end of the company's eighth contracted cargo resupply mission to the International Space Station.
A boat will take the Dragon spacecraft to a port near Los Angeles, where some cargo will be removed and returned to NASA within 48 hours. Dragon will be prepared for a return journey to SpaceX's test facility in McGregor, Texas, for processing. Dragon is currently the only space station resupply spacecraft able to return a significant amount of cargo to Earth at this time.
Dragon is returning more than 3,700 pounds of NASA cargo and science samples fr om a variety of technological and biological studies about the International Space Station. The Microchannel Diffusion study, which investigated fluids at the nanoscale, or atomic level, holds promise for a wide range of technologies. Nanofluidic sensors could measure the makeup of space station air, or be used to deliver drugs to specific places in the body, for example. This type of research is possible only on the space station, wh ere Earth's gravity is not strong enough to interact with sample molecules, so they behave more like they would at the nanoscale. Knowledge gleaned from the investigation may have implications for drug delivery, particle filtration and future technological applications for space exploration.

ЦУП. Американский грузовой корабль Dragon отстыковался от МКС
 
11.05.16 / г. Королев – В соответствии с программой полета Международной космической станции (МКС) 11 мая 2016 года автоматический транспортный корабль «Dragon» (SpaceX CRS-8 ) был отсоединен от нижнего узла модуля Harmony (Node 2) американского сегмента МКС в 14 час. 02 мин. мск.
После отвода манипулятором SSRMS от станции автоматический корабль в 16 час. 19 мин. мск. отсоединился от манипулятора и перешёл к выполнению завершающей фазы своего полёта, связанной с отстыковкой от корабля герметичного спускаемого отсека, его управляемым спуском и приводнением в Тихом океане недалеко от побережья Калифорнии (США). 
Корабль «Dragon» (SpaceX CRS-8 ) 10 апреля 2016 года доставил на станцию 3136 кг различных грузов. В том числе продовольствие и одежду для экипажа, оборудование, расходуемые материалы для использования на станции, а также экспериментальный надувной жилой модуль BEAM (Bigelow Expandable Activity Module) массой около 1400 кг, который был извлечён манипулятором из негерметичного грузового контейнера корабля и пристыкован к узловому модулю Tranquility. Раскрытие модуля планируется произвести в последних числах мая 2016 года.
В истории полётов на МКС это был второй случай, когда к станции оказались пристыкованы сразу шесть транспортных кораблей России и США – пилотируемые «Союз ТМА-19М» и «Союз ТМА-20М», грузовые «Прогресс МС», «Прогресс МС-02», «Cygnus CRS OA-6» и «Dragon» (SpaceX CRS-8 ).

Critical NASA Science Returns to Earth aboard SpaceX Dragon Spacecraft  

This series of images fr om NASA Television shows the SpaceX Dragon resupply craft moments after its release from the International Space Station's Canadarm2 robotic arm on May 11, 2016, as it steadily moves a safe distance before beginning the deorbit burn for its trip back to Earth.

A SpaceX Dragon cargo spacecraft splashed down in the Pacific Ocean at 2:51 p.m. EDT Wednesday, May 11, about 261 miles southwest of Long Beach, California, with more than 3,700 pounds of NASA cargo, science and technology demonstration samples from the International Space Station.
The Dragon spacecraft will be taken by ship to Long Beach wh ere some cargo will be removed and returned to NASA, and then be prepared for shipment to SpaceX's test facility in McGregor, Texas, for processing.
A variety of technology and biology studies conducted in the unique microgravity environment of the space station returned aboard the commercial resupply spacecraft, including research in the burgeoning field of nanotechnology. The Microchannel Diffusion study, for example, examined how microparticles interact with each other and their delivery channel in the absence of gravitational forces. In this one-of-a-kind laboratory, researchers were able to observe nanoscale behaviors at slightly larger scales – knowledge which may have implications for advancements in particle filtration, space exploration and drug delivery technologies.
CASIS Protein Crystal Growth 4 also has applications in medicine – specifically, drug design and development. Growing protein crystals in microgravity can avoid some of the obstacles inherent to protein crystallization on Earth, such as sedimentation. One investigation explored the effect of microgravity on the co-crystallization of a membrane protein with a medically-relevant compound in order to determine its three-dimensional structure. This will enable scientists to use "designer" compounds to chemically target and inhibit an important human biological pathway thought to be responsible for several types of cancer.
The spacecraft also returned to Earth the final batch of human research samples from former NASA astronaut Scott Kelly's historic one-year mission. These samples will be analyzed for studies such as Biochemical Profile, Cardio Ox, Fluid Shifts, Microbiome, Salivary Markers and the Twins Study. Additional samples taken on the ground, as Kelly continues to support these studies, will provide insights relevant for NASA's Journey to Mars as the agency learns more about how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight.
The spacesuit worn by NASA astronaut Tim Kopra during a January spacewalk also was returned for additional analysis by engineers on the ground, as NASA continues to investigate the source of water that caused and early end to the spacewalk after Kopra reported a small water bubble inside his helmet.
Dragon currently is the only station resupply spacecraft able to return a significant amount of cargo to Earth. The spacecraft lifted off from Cape Canaveral Air Force Station in Florida April 8, and arrived at the space station April 10, carrying almost 7,000 pounds of supplies and scientific cargo on the company's eighth NASA-contracted commercial resupply mission.
The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has been occupied continuously since November 2000. In that time, more than 200 people and a variety of international and commercial spacecraft have visited the orbiting laboratory. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.

Я думал, что рекордным был SES-9.. Может вы имели ввиду рекорд для Дракона?

П.С. ага.. это рекорд по загрузке дракона, рекорд по выводимой массе на НОО (в частности к МКС) за всё время пусков..

Википедия говорит, что сухая масса 4200кг+1290кг топливо + 1723 кг груз в герметичном отсеке + 1413 кг в негерметичном. Итого: 8626 кг.
SES-9 был рекордом на GTO.

У меня возникла догадка по поводу разночтения по массам Дракона в разных источниках. После выхода на орбиту от Дракона отделяются обтекатели защищающие СБ и стыковочный узел. Возможно в источнике http://www.spacelaunchreport.com/log2016.html#rate сначала давался вес корабля на старте с защитными обтекателями, а позднее без них. Может у кого-нибудь есть точные веса этих обтекателей?
