Filled with almost 2,700 pounds of valuable scientific experiments and other cargo, a SpaceX Dragon resupply spacecraft is set to leave the International Space Station Tuesday, Aug. 27. NASA Television and the agency's website will broadcast its departure live beginning at 10:15 a.m. EDT.

Robotic flight controllers at mission control in Houston will issue remote commands at 10:42 a.m. to release Dragon from the Earth-facing port of the Harmony module using the station's Canadarm2 robotic arm. Expedition 60 Flight Engineer Christina Koch of NASA will back up the ground controllers and monitor Dragon's systems as it departs the orbital laboratory.

Dragon will fire its thrusters to move a safe distance from the station, then execute a deorbit burn around 3:22 p.m. as it heads for a parachute-assisted splashdown around 4:21 p.m. in the Pacific Ocean, some 300 miles southwest of Long Beach, California. The deorbit burn and splashdown will not air on NASA TV.

Dragon launched on the SpaceX Falcon 9 rocket July 25 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, and arrived at the space station two days later.

Some of the scientific investigations Dragon will return to Earth include:

Bio-Mining in Microgravity
The Biorock investigation provides insight into the physical interactions of liquid, rocks and microorganisms in microgravity and improving the efficiency and understanding of mining materials in space. Bio-mining eventually could help explorers on the Moon or Mars get needed materials on site, lessening the need for precious resources from Earth and reducing the amount of supplies explorers must take with them.

Mechanisms of Moss in Microgravity
Space Moss compares mosses grown aboard the space station with those grown on Earth to determine how microgravity affects its growth, development, and other characteristics. Tiny plants without roots, mosses need only a small area for growth, an advantage for their potential use in space and future bases on the Moon or Mars. This investigation also could yield information that aids in engineering other plants to grow better on the Moon and Mars, as well as on Earth.

Improving Tire Manufacturing from Orbit
The Goodyear Tire investigation uses microgravity to push the limits of silica fillers for tire applications. A better understanding of silica morphology and the relationship between silica structure and its properties could provide improvements for increased fuel efficiency, which would reduce transportation costs and help to protect Earth's environment.

These are just a few of the hundreds of investigations aimed at keeping astronauts healthy during space travel and demonstrating technologies for future human and robotic exploration beyond low-Earth orbit, including missions to the Moon by 2024 and on to Mars. Space station research also provides opportunities for other U.S. government agencies, private industry, and academic and research institutions to conduct microgravity research that leads to new technologies, medical treatments, and products that improve life on Earth.

For more than 18 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 230 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 2,500 research investigations from researchers in 106 countries.

Scientific samples make the journey back to Earth aboard SpaceX's Dragon

On July 27, 2019, a Dragon cargo spacecraft arrived at the International Space Station carrying dozens of scientific experiments. Now, Dragon heads home. It brings samples, hardware and data from completed investigations back to Earth on its return trip, with undocking from the station currently scheduled for one month after arrival: August 27.

Here are details on some of the investigations returning to the ground for further analysis and reporting of results.

A cinematic look at life and science aboard the space station

The ISS Experience is creating a cinematic virtual reality (VR) film from footage taken during the yearlong investigation covering different aspects of crew life, execution of science and the international partnerships involved on the space station. The immersive VR film will give audiences on Earth an up close and personal taste of the challenges of adaptation to life in space, the work and science, and the human interaction between crew members.

Developers Felix & Paul Studios, in partnership with private space services firm NanoRacks and the ISS National Lab, launched two cinematic virtual reality camera systems to the space station on a SpaceX Dragon cargo spacecraft in December 2018. The crew films less than four hours each week. Every week or so, they transfer footage from the camera onto solid state drives – an original and a backup – for storage and downlinking. One of each pair of drives eventually physically returns to Earth for editing and production and astronauts then can reuse the other one.

Seeking Alzheimer's understanding in microgravity

Amyloid fibrils, a conglomeration of proteins that can build up in the body, are associated with a number of neurodegenerative diseases such as Alzheimer's and Parkinson's. The Amyloid Aggregation investigation assesses whether microgravity affects formation of these fibrils, which could represent a possible risk to astronauts on long flights.

Samples exposed to microgravity return to Earth using the General Laboratory Active Cryogenic ISS Experiment Refrigerator (GLACIER), a facility that maintains a temperature of -20°C. Teams on the ground must quickly retrieve the equipment and keep the samples at -20°C until delivery to the principal investigators for analysis.

From microgravity lab to manufacturing facility

Physical Optics Corporation's Fiber Optic Production investigation created optical fibers with high commercial value on the space station using a blend of materials called ZBLAN. Studies suggest that ZBLAN optical fibers produced in microgravity should be higher quality than those produced on Earth. On Earth, ZBLAN optical fibers offer high bandwidth for the telecommunications industry, and potential applications for laser surgery, remote sensing and environmental monitoring.

The fiber produced on the space station is returning to Earth for testing to help verify previous studies and guide future efforts to manufacture large volumes of such fiber in microgravity.

Testing flexible fuel tanks

Furphy tested the transfer of fluids from a rigid tank to a flexible tank that can launch collapsed and deploy as it fills. This capability would make it possible to fuel small satellites in orbit rather than prior to launch, potentially saving launch mass and volume. This first microgravity test verified tank dynamics including slosh and retention of angular momentum. Flexible fuel tanks also have potential applications on Earth, including supporting operations in remote and harsh environments and in disaster relief.

The investigation used a rigid tank, delivered to the space station filled with water, and a FlexTank™ made from silicone elastomer, which arrived empty and compressed. After the tests, crew offloaded the water to the station's water supply. The tanks are returning to Earth aboard the Dragon.

Other investigations returning on the Dragon:

The BioRock investigation examines interactions between microbes and rocks and physical and genetic changes in the microbes in space to support future acquisition of materials in space through biomining. After culturing and fixation on the space station, the crew placed samples into cold storage at 4°C for return to the investigation team on the ground for analysis.

LMM Biophysics 6 crystallized two proteins of interest in cancer treatment and radiation protection. The microgravity-grown crystals return to the ground for comparison to control crystallization experiments performed on Earth, using microscopic images, X-Ray diffraction analysis and structural analysis.

Synchronized Position Hold, Engage, Reorient, Experimental Satellites, or SPHERES, are bowling-ball sized satellites used to study formation flying, control algorithms, and material science. First sent to the station during Expedition 13 in 2006, these satellites have been employed in a dozen different investigations. The Dragon brings back hardware from two recent ones that examined the behavior of fluids in microgravity, SPHERES Tether Slosh and SPHERES-Slosh.

The Cell Science-02 investigation examined the effects of microgravity on healing and tissue regeneration and on the agents that induce that healing. Cultures were maintained on-orbit for approximately 21 days and then preserved and placed in -80˚C cold stowage for return to NASA's Johnson Space Center. They will then ship to the research team within 24 hours of payload handover.

The Goodyear Tire investigation evaluates the creation of silica fillers using traditional techniques but in microgravity, potentially yielding results not possible on Earth. After processing, the six rubber samples return via cold-stowage to the Goodyear Research facility for analysis.

Mobile Companion examined the efficiency and acceptance by the crew of support from artificial intelligence (AI) during long-term missions in space. AI could provide operational support that reduces the amount of stress and workload on human crew members. Investigation hardware returns to Earth on Dragon.

Space Moss compares mosses grown aboard the space station with those grown on Earth to determine how microgravity affects growth, development, gene expression, photosynthesis and other features. Crew members fixed some of the mosses using a Chemical Fixation Bag and stored the rest for live return.

Корабль Dragon вернется с МКС на Землю с результатами экспериментов
06:36 27.08.2019

ВАШИНГТОН, 27 авг - РИА Новости. Грузовой космический корабль Dragon компании SpaceX во вторник покинет Международную космическую станцию (МКС), он доставит на Землю результаты новейших научных экспериментов и фильм о жизни в космосе, сообщило НАСА.

"Dragon, отстыковавшись от станции 27 августа, ровно через месяц после прибытия, привезет обратно на Землю образцы (экспериментов), оборудование и данные о завершенных (научных) исследованиях", - сообщило НАСА. Корабль привезет на Землю около 1,5 тонны груза, в том числе более тонны результатов научных экспериментов.

Отстыковка корабля, прибывшего на МКС 27 июля, намечена на 17:42 мск. Корабль отстыкует от станции механический манипулятор Canadarm2. Через несколько часов после того, как он покинет орбитальную станцию, аппарат приводнится в Тихом океане. Ожидается, что это произойдет в 480 километрах от побережья Калифорнии в 23:21 мск.

Как сообщило НАСА, на корабле, который является на сегодня единственным аппаратом, способным доставлять грузы с МКС на Землю, вернутся результаты экспериментов в области медицины, создания оптических волокон, мобильных топливных баков и другие.

Помимо прочего Dragon привезет домой фильм о жизни на МКС. В течение нескольких месяцев на орбитальной станции с помощью технологии виртуальной реальности снимали повседневную жизнь экипажа, и теперь материалы об этом вернутся на Землю. "Фильм-погружение с помощью эффекта виртуальной реальности позволит зрителям на Земле взглянуть и почувствовать сложности адаптации к жизни в космосе, работы в космосе и человеческим отношениям между членами экипажа", - сообщили в НАСА накануне возвращения корабля. Как рассказали в американском космическом ведомстве, проект начался в декабре 2018 года, когда на орбиту доставили две специальных камеры. Съемки велись каждую неделю в течение четырех часов. По возвращении на Землю отснятый материал будет смонтирован для будущего фильма.

A commercial Dragon cargo capsule is heading back to Earth today to conclude a 31-day stay at the International Space Station.

The automated Dragon supply ship will be released fr om the space station's Canadian-built robotic arm at 10:59 a.m. EDT (1459 GMT), around 15 minutes later than previously planned to allow for better lighting conditions.

Once Dragon flies to a safe distance from the station, the spacecraft will close the door to its guidance, navigation and control bay, then fire its Draco thrusters around 3:22 p.m. EDT (1922 GMT) for a deorbit burn to target splashdown in the Pacific Ocean.

The reusable cargo capsule will jettison its disposable trunk section to burn up in the atmosphere. The Dragon's pressurized compartment, protected by a carbon ablative heat shield, will enter the atmosphere heading northwest-to-southeast over the Pacific Ocean.

Three main parachutes will unfurl to slow the capsule for splashdown at 4:21 p.m. EDT (2021 GMT) around 300 miles (500 kilometers) southwest of Long Beach, California.

A SpaceX recovery team in the Pacific will hoist the capsule out of the water and return the craft to the Port of Los Angeles, wh ere SpaceX will hand over time-sensitive research specimens and experiments to NASA and other science teams.

The Dragon cargo capsule is packed with nearly 2,700 pounds (1,224 kilograms) of equipment for today's trip back to Earth.

SpaceX's 18th resupply mission to the space station arrived at the orbiting complex July 27, two days after launch from Cape Canaveral aboard a Falcon 9 rocket.

The automated Dragon cargo capsule delivered 5,097 pounds (2,312 kilograms) of supplies, equipment and research investigations for the station's six-person Expedition 60 crew.

The cargo load included a new $22.5 million docking adapter to accommodate arrivals of Boeing and Starliner commercial crew capsules. Two NASA astronauts helped install the new docking mechanism -- the second such adapter on the station -- during an Aug. 21 spacewalk.
