Dragon Released from Station Carrying Science for Earth-Analysis

Mark Garcia
Posted Jan 7, 2020 at 5:26 am


The SpaceX Dragon cargo craft is pictured moments before its release from the Canadarm2 robotic arm on June 3, 2019.

The SpaceX Dragon cargo spacecraft released from the International Space Station at 5:05 a.m. EST after flight controllers in Houston delivered remote commands to the station's Canadarm2 robotic arm. Expedition 61 Station Commander Luca Parmitano of ESA (European Space Agency) will back up the ground controllers and monitor Dragon's systems as it departs the orbital laboratory.

Next up, Dragon will fire its thrusters to move a safe distance from the station, then execute a deorbit burn as it heads for a parachute-assisted splashdown around 10:41 a.m. in the Pacific Ocean southwest of Long Beach, California. The splashdown will not air on NASA TV.

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

Tiny Radiation Resistors

Rotifer-B1 examines the effects of spaceflight on tiny aquatic animals, called rotifers, which are found in freshwater ecosystems and soil and are highly resistant to radiation on Earth. The investigation specifically looks at the metabolism and genome of the rotifer Adineta vaga to determine whether they have similar adaptation mechanisms in microgravity.

Mice in Space

Rodent Research-19 examines myostatin and activin, molecular signaling pathways that influence muscle degradation, as possible targets for preventing muscle and bone loss during spaceflight and enhancing recovery following return to Earth. This study also could support the development of therapies for a wide range of conditions that cause muscle and bone loss on Earth.

Finding the Perfect Solution

On Earth, our bodies deal with low-level radiation through a naturally occurring protein that helps our body safely process it. The Growth of Large, Perfect Protein Crystals for Neutron Crystallography (Perfect Crystals) study, aims to help scientists find a way to deal with the problem of radiation during long-duration spaceflight missions using the same protein that is already at work in our bodies.

Convection and Crystallization in Microgravity

The Polymer Convection study examines the effects of gravity on formation and crystallization of Broadband Angular Selective Material (BASM), an optical material with the ability to control the reflection and absorption of light. BASM has applications in polymer packaging, optical films, solar power and electronic displays.

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.

Грузовой корабль Dragon отстыковался от МКС
Первоначально посадка корабля планировалась на 5 января

НЬЮ-ЙОРК, 7 января. /ТАСС/. Американский грузовой корабль Dragon во вторник отстыковался от Международной космической станции (МКС). Трансляция операции идет на сайте NASA.

Дистанционный манипулятор Canadarm-2 отведен от корабля в 05:05 по времени восточного побережья США (13:05 мск). Посадка корабля с 1,6 тонны груза запланирована на 10:47 по времени восточного побережья США (18:47 мск).

Первоначально возвращение корабля планировалось на 5 января, однако, как отмечается на сайте NASA, было принято решение отложить посадку из-за неблагоприятных погодных условий в Тихом океане к юго-западу от Лонг-Бич (штат Калифорния).

Спойлер

Запуск корабля ракетой-носителем Falcon 9 был осуществлен 5 декабря с космодрома на мысе Канаверал. Он доставил на МКС 2,5 тонны грузов, в том числе 998 кг грузов для серии из 38 научных экспериментов - многоканальный спектрометр, прибор для изучения процесса горения в условиях микрогравитации, медицинскую аппаратуру для оценки состояния мускулов астронавтов в условиях орбитального полета, оборудование для эксперимента по пивоварению, а также "отель для роботов" - платформу RiTS (Robot Tool Stowage) для установки на внешней поверхности МКС, где будут храниться роботизированные системы в период, когда они не используются астронавтами.

Нынешний полет корабля Dragon к МКС - уже 19-й в рамках осуществляемой NASA программы коммерческой доставки грузов на МКС. Для полета использована капсула, уже дважды - в 2014 и 2017 годах - летавшая к МКС.

В настоящее время на МКС работают россияне Александр Скворцов и Олег Скрипочка, американцы Эндрю Морган, Кристина Кук и Джессика Меир, а также астронавт Европейского космического агентства итальянец Лука Пармитано.

Космический корабль Cargo Dragon успешно приводнился в Тихом океане

Москва. 7 января. INTERFAX.RU - Американский грузовой космический корабль Cargo Dragon, ранее отстыковавшийся от Международной космической станции, в 18:47 по Москве во вторник штатно приводнился в Тихом океане, сообщила компания-разработчик SpaceX.

Как отметили в компании, завершена третья миссия этого корабля на МКС и обратно.

Приводнение было осуществлено в запланированном морском районе в 326 км к юго-западу от американского города Лонг-Бич (штат Калифорния). В месте посадки спускаемую капсулу ожидало поисково-спасательное судно NRC Quest компании SpaceX, которое обеспечит ее доставку на сушу.

Корабль привез на Землю более 1,5 тонн груза, в том числе результаты ценных научных экспериментов, проведенных на МКС.

Как сообщалось, отстыковка "грузовика" от МКС после месячного пребывания в ее составе была совершена в 13:05 по Москве во вторник.

ISS Daily Summary Report – 1/06/2020

Rodent Research-19 (RR-19):

The crew transferred the remaining subjects into the Dragon capsule. Mighty Mice in Space: Preclinical Evaluation of a Broad Spectrum Myostatin Inhibitor to Prevent Muscle and Bone Loss Due to Disuse uses rodent models on the ISS to investigate the potential benefits of targeting the myostatin (MSTN) and activin signaling pathways to prevent skeletal muscle and bone loss during spaceflight and on the recovery of muscle and bone following return to Earth. This research could provide valuable preclinical data to support clinical trials for MSTN therapies for a wide range of conditions that affect muscle and bone health. Such research is particularly important for conditions that involve disuse muscle atrophy (muscle wasting due to immobility or lessened activity)—for example, patients recovering from hip fracture surgery, intensive care patients, and the elderly.

Advanced Nano Step:

The crew installed the Return Step Specimen Cell bag in preparation for return. The Effects of Impurities on Perfection of Protein Crystals, Partition Functions, and Growth Mechanisms (Advanced Nano Step) experiment monitors and records how the incorporation of specific impurity molecules affect the development and quality of protein crystals, as they grow in a quartz cell aboard the International Space Station (ISS). The crystals grown on the ISS are returned to Earth, and characterized using synchrotron X-ray diffraction. The protein crystal and impurity interactions are managed and monitored jointly by both scientists on the ground and the ISS crew.

Space Biofilms:

The crew removed nine GAPs (Group Activation Packs) and stowed them into the Dragon capsule for return. The Characterization of Biofilm Formation, Growth, and Gene Expression on Different Materials and Environmental Conditions in Microgravity (Space Biofilms) investigation characterizes the mass, thickness, structure, and associated gene expression of biofilms that form in space by analyzing different microbial species grown on different materials. Biofilm formation can cause equipment malfunction and human illnesses, and could be a serious problem on future long-term human space missions.

[свернуть]

BioFabrication Facility (BFF):

The crew retrieved the two BFF bags and prepped the bags for return on SpX-19. The BFF is dedicated to manufacturing human organs and tissues in space, primarily for use by patients on Earth. Besides printing tissue, the BFF also can help maintain the health of deep space exploration crews by producing food and personalized pharmaceuticals on demand.

Dragon Splashes Down in Pacific Returning Science and Cargo

Mark Garcia
Posted Jan 7, 2020 at 12:44 pm


A camera on the tip of the Canadarm2 robotic arm views the SpaceX Dragon as it separates from the International Space Station.

The SpaceX Dragon spacecraft splashed down at 10:42 a.m. in the Pacific Ocean about 271 miles southwest of Long Beach, California, marking the end of the company's 19th contracted cargo resupply mission to the International Space Station for NASA.

A key component being returned aboard Dragon is a faulty battery charge-discharge unit (BCDU), which failed to activate following the Oct. 11 installation of new lithium-ion batteries on the space station's truss. The BCDU was removed and replaced during a spacewalk Oct. 18 by Expedition 61 flight engineers Christina Koch and Jessica Meir of NASA. The unit are being returned to teams on Earth for an evaluation and repair.

Dragon launched on the SpaceX Falcon 9 rocket Dec. 5 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, and arrived at the station two days later with almost 3,400 pounds of science, supplies and cargo.
