SpaceX-20 (SpX-20) Dragon Cargo Operations:
Today, the crew continued to perform Dragon cargo operations in preparations for Dragon departure on April 6, 2020.

Water Processor Assembly (WPA) Multi-filtration (MF) Bed Sample Collection:
Today, the crew performed a Life Support Rack (LSR) hose reconfiguration in preparation for a WPA MF Bed return sample collection. The crew previously experienced an issue with connecting a hose normally used to take MF bed samples; and as a result, ground teams had the crew reconfigure the LSR hoses to free up a like hose to re-attempt return sampling. The hose taken from the LSR was connected to the WPA nominally and the WPA MF Bed SpX-20 return sample was collected.

Systems Operations Data File (SODF) DEPLOY:
Today, the crew replaced their Medical Checklists and EVA wrist Cuff Checklists with updated documentation delivered on SpX-20. The retired EVA Cuff Checklists will be returned on SpX-20.

...
The Dragon supply ship is scheduled to be released fr om the space station's robotic arm at 9:52 a.m. EDT (1352 GMT) Monday, heading for re-entry and a parachute-assisted splashdown in the Pacific Ocean southwest of Los Angeles.

Before Monday's release, the Dragon will be unberthed from the station's Harmony module using the robot arm and maneuvered to a position around 30 feet, or 10 meters, below the research complex.

Closing out a nearly 31-day mission, the unpiloted cargo capsule will move a safe distance from the station before firing its Draco thrusters in a braking burn to slow down and re-enter the atmosphere. After jettisoning its disposable trunk, the pressurized capsule will plunge into the atmosphere, protected by a high-temperature heat shield, then deploy three main parachutes for a relatively gentle splashdown in the Pacific Ocean around 3:40 p.m. EDT (1940 GMT).

A SpaceX recovery team will be on station to pull the reusable spacecraft from the sea and haul it to the Port of Los Angeles, wh ere teams will begin handing over time-sensitive experiment specimens and more than 4,000 pounds of cargo to NASA.

The Dragon capsule's return to Earth on Monday will mark the final flight of SpaceX's first-generation cargo vehicle after 20 trips to the space station. The specific spacecraft currently at the station is on its third mission in space.

SpaceX's future resupply missions will use the upgraded Dragon 2 spaceship, which comes in crew and cargo variants.

Editor's note, April 3, 2020: Dragon's departure from the International Space Station has been rescheduled to Tuesday, April 7. NASA TV coverage begins at 8:45 a.m. EDT.

Filled with more than 4,000 pounds of valuable scientific experiments and other cargo, a SpaceX Dragon resupply spacecraft is set to leave the International Space Station Monday, April 6. NASA Television and the agency's website will broadcast its departure live beginning at 9:30 a.m. EDT.

Robotic flight controllers at mission control in Houston will issue commands at 9:52 a.m. to release Dragon using the station's Canadarm2 robotic arm. Expedition 62 Flight Engineer Andrew Morgan 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 as it heads for a parachute-assisted splashdown around 3:40 p.m. in the Pacific Ocean, southwest of Long Beach, California. The splashdown will not air on NASA TV.

Dragon launched on the SpaceX Falcon 9 rocket March 6 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida and arrived at the space station three days later.

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.

НАСА отложило возвращение грузового корабля Dragon с МКС
11:06 04.04.2020

МОСКВА, 4 апр - РИА Новости. Грузовой корабль Dragon компании SpaceX Илона Маска вернется с Международной космической станции на Землю 7 апреля, на день позже, чем планировалось, сообщило НАСА.

Ранее НАСА сообщало, что прибывший на станцию в марте корабль покинет ее и приводнится в Тихом океане 6 апреля.

На сайте НАСА без указания причин отмечается, что возвращение Dragon на Землю отложено на сутки.

Согласно новому графику, 7 апреля корабль с помощью дистанционного манипулятора будет отстыкован от МКС и в 17.15 мск его отделят от манипулятора. В тот же день Dragon сойдёт с орбиты, и его возвращаемый аппарат с грузами приводнится недалеко от западного побережья США.

3D Printing, Biology Research Make the Journey Back to Earth aboard SpaceX's Dragon

On March 9, 2020, a Dragon cargo spacecraft arrived at the International Space Station carrying dozens of scientific experiments as a part of SpaceX's 20th cargo resupply mission. Now, Dragon heads home. On April 7, it is scheduled to undock from station, bringing samples, hardware and data from completed investigations back to Earth on its return trip.

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

Generating a nutritional meal

Planning ways to supply food for a multi-year mission on the Moon or Mars while keeping astronauts healthy on the long trip may require making fresh food and nutrients in space. BioNutrients demonstrates a technology that enables on-demand production of nutrients needed for during long-duration space missions.

The process uses microbes, such as baker's yeast, expressly engineered to make fresh nutrients for human consumption starting from dry powdered media — food for the yeast — and water. The fresh nutrients can supplement potential vitamin losses from food that is stored for very long periods. Over the five-year period of the demonstration, astronauts intermittently activate specially designed packets containing the yeast — or other microorganisms, in the future — and their food. They warm the packets for two days to allow the yeast to do its job, growing and producing the desired nutrients, and then freeze them for return to Earth for analysis. These tests will allow scientists to check how long their specially engineered yeast can be stored on the shelf and still be able to churn out fresh nutrients that humans need to stay healthy in space. Some samples will be returning on this SpaceX Dragon capsule. 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, has proven difficult in Earth's gravity. Under Earth's gravity, an initial scaffolding, or support structure, is necessary to form the desired shape of the tissue. The BioFabrication Facility (BFF) attempts to take the first steps toward printing human organs and tissues in microgravity using ultra-fine layers of bioink that may be several times smaller than the width of a human hair. This research is part of a long-term plan to manufacture entire human organs in space using refined biological 3D printing techniques.

Launched to station in July 2019 on the 18th SpaceX cargo resupply flight, the facility now comes back to Earth. According to Techshot President and CEO John Vellinger, the facility has proven basic functionality. The team is bringing the facility back to Earth to make upgrades that will enable high throughput use when it returns to the space station.

Helping the heart

The Engineered Heart Tissues 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. The engineered heart tissues, or EHTs, are complex 3D structures, each about the size of a few grains of rice. These structures are more similar to tissues in the body than flat cell cultures in a petri dish or those floating in a flask of liquid.

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. The hardware developed for the experiment also has created advanced, more efficient and more cost-effective technology for use on Earth. Researchers are bringing some EHTs back to Earth to see whether they recover from changes thought to occur in microgravity.

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. In spacecraft, biofilm formation can cause equipment malfunction and human illness, and it could pose a serious problem on future long-term human space missions. 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.

Examining amyloid formation in microgravity

The Ring Sheared Drop investigation takes advantage of the fact that fluids float in microgravity, allowing researchers to examine formation of amyloid fibrils in liquids held together by surface tension rather than by a container. Amyloids are abnormal fibrous deposits found in organs and tissues and are associated with neurodegenerative conditions such as Alzheimer's disease. These proteins can denature -- or lose characteristic properties -- and precipitate, or come out of solution. As they accumulate over time, they may disrupt the healthy function of tissues and organs. Results from this experiment could contribute to a better understanding of and treatments for these neurodegenerative diseases. Data on the flow of liquids without the complications associated with solid walls also could contribute to development of advanced materials. Samples from this experiment are returning on Dragon.
