Dragon's third and final departure burn is complete, moving the craft beyond the 200-meter keep-out sphere, an imaginary bubble around the space station.

"That was the last time the arm and Dragon will meet that way so it was fun to watch," said Drew Morgan, a flight engineer on the International Space Station.

Future Dragon cargo missions will not be grappled or released by the Canadian-built robotic arm, but will instead directly dock with the space station.

"Congratulations to the SpaceX team and the teams all around the world for the successful Dragon mission over the last month and wrapping up Expedition 62."

Morgan and crewmates Jessica Meir and Oleg Skripochka will be joined by three fresh crew members Thursday, then they will head for landing in Kazakhstan on April 17 on a Russian Soyuz capsule.

Космический корабль Dragon покинул МКС и возвращается на Землю
16:25 07.04.2020

ВАШИНГТОН, 7 апр – РИА Новости. Грузовой космический корабль Dragon покинул Международную космическую станцию (МКС) и возвращается на Землю с научными материалами с орбиты, НАСА ведет прямую трансляцию.

Механическая рука Canadarm2 по команде специалистов с Земли "отпустила" космический корабль в 9.06 по времени Восточного побережья США (16.06 мск).

Космический корабль, принадлежащий частной компании SpaceX, увозит со станции около 1,8 тысяч килограмм груза, прежде всего, результаты научных экспериментов, идущих на орбите.

Позднее во вторник Dragon должен приводниться в Тихом океане недалеко от побережья Калифорнии. Аппарат является на сегодня единственным беспилотным космическим кораблем, способным доставлять груз с МКС на Землю.

Американский корабль Dragon совершил приводнение в Тихом океане
НЬЮ-ЙОРК, 7 апреля. /ТАСС/. Американский космический корабль Dragon совершил посадку на воду в Тихом океане неподалеку от побережья штата Калифорния. Об этом сообщила во вторник в своем Twitter компания SpaceX.
"Подтверждаем удачное приводнение корабля Dragon", - указывается в сообщении. В компании отметили, что нынешняя миссия стала 20-й по счету и заключительной для кораблей Dragon первого поколения. В дальнейшем доставку грузов на Международную космическую станцию (МКС) будут совершать корабли нового поколения.

"Ранее"

Ранее во вторник корабль отстыковался от МКС. В начале марта он доставил на Международную космическую станцию 1950 кг грузов, в том числе научное оборудование для биомедицинских исследований и аппаратуру для изучения химических реакций в условиях микрогравитации.

[свернуть]

На Землю он вернул около 2 тонн грузов, в том числе результаты научных экспериментов по программе BioNutrients по получению питательных веществ для экипажей в ходе долговременного полета, по программе BioFabricationFacility по проверке возможности создания человеческих органов в условиях микрогравитации и образцы, полученные в рамках программы Space Biofilms по изучению роста микроорганизмов во влажных средах.
Сейчас на борту МКС работают россиянин Олег Скрипочка, астронавты НАСА Эндрю Морган и Джессика Меир.

Dragon Leaves Station, Returns to Earth with Valuable Science

SpaceX's Dragon cargo spacecraft splashed down in the Pacific Ocean at 2:50 p.m. (11:50 a.m. PDT), approximately 300 miles southwest of Long Beach, California, marking the end of the company's 20th contracted cargo resupply mission to the International Space Station for NASA. The spacecraft returned more than 4,000 pounds of valuable scientific experiments and other cargo.

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

Generating a nutritional meal

Planning ways to supply food for a multi-year mission on the Moon or Mars may require making food and nutrients in space. BioNutrients demonstrates a technology that enables on-demand production of nutrients needed during long-duration space missions. Although designed for space, this system also could help provide nutrition for people in remote areas of our planet.

Toward printing human organs in space

Biological printing of the tiny, complex structures found inside human organs, such as capillaries, is difficult in Earth's gravity. The BioFabrication Facility (BFF) attempts to take the first steps toward the printing of human organs and tissues in microgravity. The facility may also help maintain the health of crews on deep space exploration missions by producing food and personalized pharmaceuticals on demand.

Helping the heart

The Engineered Heart Tissues (EHTs) study looks at how human heart tissue functions in space. It uses unique 3D tissues made from heart cells derived from human induced Pluripotent Stem Cells (hiPSCs), essentially adult stem cells. Researchers expect significant differences in function, structure and gene expression between EHTs in microgravity and those on the ground. Understanding these differences could help them find ways to prevent or mitigate problematic changes on future long-duration missions.

Biofilm festival

Samples from the Space Biofilms investigation, which examines microbial species and their formation of biofilms, are returning on Dragon. Biofilms are collections of one or more types of microorganisms – including bacteria, fungi and protists – that grow on wet surfaces. Better control of biofilms may help maintain crewed spacecraft and protect the health and safety of crew members as well as help prevent the introduction of Earth-based microbes to planetary bodies on which humans land.

These are just a few of the hundreds of investigations providing opportunities for 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. Conducting science aboard the orbiting laboratory will help us learn how to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars.

For almost 20 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. As a global endeavor, 239 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 2,800 research investigations from researchers in 108 countries.

After about 20 minutes of traveling from the hold point, recovery ship NRC Quest has arrived at the splashdown location of the CRS-20 Dragon.  Fast-approach boats will be used to collect up the parachutes and Dragon will soon be lifted onboard.
