The Expedition 59 crew is starting the weekend preparing the SpaceX Dragon cargo craft for its departure from the International Space Station on Monday. The space residents are also juggling a variety of research work and lab maintenance tasks today.

NASA TV is broadcasting the robotic release of Dragon from the station live on NASA TV beginning Monday at 11:45 a.m. EDT.  Robotics controllers will command the Canadarm2 robotic arm to release the space freighter around 12:09 p.m. while astronaut David Saint-Jacques monitors from the cupola. Dragon will splashdown in the Pacific about 5:48 p.m. and will not be seen on NASA TV.

Several critical experiments have wrapped up aboard the orbiting lab with the completed results and hardware being packed inside the Dragon this weekend. After the space freighter splashes down Monday, it will be towed to shore where the finalized research will be distributed to labs around the world for analysis.

Astronauts Anne McClain and David Saint-Jacques are cleaning up and inspecting the Life Sciences Glovebox (LSG) today. This comes after the crew completed a month-long study of the immune system’s response to weightlessness inside the LSG. Samples from that study will also return to Earth aboard Dragon Monday.

The pair first joined Flight Engineer Nick Hague during the morning checking out space biology hardware and transferring more frozen research samples into Dragon’s science freezers. Hague and McClain then participated in regularly scheduled eye exams in the afternoon.

Christina Koch of NASA is helping cosmonauts Oleg Kononenko and Alexey Ovchinin clean up after the duo’s spacewalk on Wednesday. She stowed the U.S. tools they used back in the Quest airlock while the cosmonauts serviced their Russian Orlan spacesuits in the Pirs airlock.

Two Expedition 59 cosmonauts are finalizing reviews before Wednesday morning’s spacewalk for maintenance outside the International Space Station. Meanwhile, the orbital residents are also readying completed experiments for return to Earth inside the SpaceX Dragon cargo craft next week.

Commander Oleg Kononenko is set to begin his fifth career spacewalk Wednesday at 11:44 a.m. EDT. He will lead first-time spacewalker Alexey Ovchinin during the six-hour-15-minute excursion on the Russian segment of the orbital lab. They will retrieve experiment hardware, clean lab windows and jettison old cables among other tasks.

The duo reviewed their spacewalk tasks and worksites alongside NASA astronaut Christina Koch this morning. Koch will assist the pair with their Russian Orlan spacesuits in the Pirs airlock before and after Wednesday’s spacewalk.

The SpaceX Dragon launched a multitude of life science experiments studying immunology, crystallography, microphysiology and other space phenomena to the station May 4. The completed research samples and science hardware will now return to Earth inside Dragon after it departs the station’s Harmony module June 3. NASA Flight Engineer Anne McClain is readying the commercial space freighter for departure and beginning the work to pack the finalized experiments for analysis in labs across the globe.

Astronauts Nick Hague and David Saint-Jacques spent Tuesday maintaining station systems and hardware. Hague first measured airflow in the Japan’s Kibo laboratory module before routing power cables in the U.S. Destiny laboratory module. Saint-Jacques reconfigured a robotics computer and routed communication cables then checked components on the Advanced Resistive Exercise Device.

Four Expedition 59 astronauts spent Friday investigating a multitude of space biology phenomena while two cosmonauts continued preparing for an upcoming spacewalk. International Space Station hardware is also ready for return to Earth inside the SpaceX Dragon resupply ship.

The crew is exploring how space impacts a variety of microscopic physiological processes today to get humans ready to go to the Moon in 2024. DNA, pathogens and microalgae as well as their benefits and risks to astronauts are just some of the microbiological systems scientists are studying in space.

The Bio-Analyzer is a new device from the Canadian Space Agency (CSA) being tested aboard the space station for its ability to process and analyze biological samples quickly. CSA astronaut David Saint-Jacques added his blood samples to the biomedical device today so doctors could check his biomarkers from the ground.

NASA astronaut Christina Koch studied a pair of yeast strains today using the miniPCR hardware for the Genes In Space-6 study. The experiment is exploring how space radiation damages DNA and how the cell repair mechanism works in microgravity. Koch later tended to plants grown inside the Veggie PONDS botany facility.

More research into why pathogens become more virulent in space continued today as Flight Engineer Nick Hague processed culture samples for the microbiology study. Hague also checked on microalgae sample packs that may serve as a dietary supplement for future astronauts.

Hague also configured a variety of space biology hardware, both large and small, ensuring critical research operations continue successfully on the orbital lab. He first worked on a pair of refrigerator-sized Human Research Facility racks before checking out the shoebox-sized TangoLab-1 facility that enables a variety of tissue, cell and botany investigations.

Anne McClain of NASA turned her attention Friday to old hardware disconnected during a spacewalk earlier this year. She will retrieve a failed Battery Charge Discharge Unit (BCDU) resting outside the Kibo laboratory module’s airlock and bring it inside the station. The Canadarm2’s robotic hand, known as Dextre, removed the BCDU early Thursday from a truss structure logistics carrier and placed it outside Kibo. The BCDU will be packed aboard the SpaceX Dragon cargo craft for analysis after it returns to Earth June 3.

Two cosmonauts are getting ready for the fourth station spacewalk this year scheduled to take place May 29. Commander Oleg Kononenko and Flight Engineer Alexey Ovchinin tagged up with Russian spacewalk specialists on the ground today for assistance setting up their Orlan spacesuits. The duo will remove experiments, sample station surfaces and jettison obsolete hardware during their six-hour excursion.

Robotics and Space Biology Today as Cosmonauts Look to Next Spacewalk

A pair of robotic arms from Canada and Japan continued swapping experiment hardware on the International Space Station over the weekend. Meanwhile, the Expedition 59 crew started the week exploring robotics and biology today while a pair of cosmonauts look to the next spacewalk.

The 57.7-foot-long Canadarm2 robotic arm started removing a pair of external investigations last week from the SpaceX Dragon’s unpressurized trunk. The remotely controlled Canadarm2 first grabbed the new Orbiting Carbon Observatory-3 (OCO-3) then handed it off to the Japan Aerospace Exploration Agency’s (JAXA) robotic arm for installation on the Kibo lab module’s external pallet.

The Canadarm2 next removed the Space Test Program-Houston 6 (STP-H6) experiment from Dragon and installed it on the station’s truss structure. STP-H6 provides a platform for studying space physics to improve spacecraft navigation and communication techniques. The Canadian robotic arm then removed the completed SCAN radio communications study from the truss and placed it inside Dragon’s trunk.

JAXA’s robotic arm also retrieved the Cloud-Aerosol Transport System (CATS) experiment from the station and handed it off to the Canadarm2 for installation inside Dragon’s trunk. CATS successfully began demonstrating atmospheric monitoring after its delivery aboard a SpaceX Dragon cargo craft in January 2015. CATS and SCAN will now burn up in the atmosphere when Dragon’s trunk separates from the resupply ship before it returns to Earth at the end of May.

Back inside the orbital lab today, NASA astronaut Anne McClain calibrated the Astrobee and mapped the Kibo lab module with the free-flying robotic assistant. Flight Engineers Nick Hague and Christina Koch continued exploring how space changes the immune system, pathogens and kidney cells.

Two cosmonauts, Commander Oleg Kononenko and Flight Engineer Alexey Ovchinin, are planning for the fourth spacewalk at the station this year on May 29. The duo is timelined for about six hours of experiment retrieval work, window cleaning and sample collecting on the station’s Russian segment.

The Expedition 59 crew focused intensely on human research today to improve the health of people on Earth and in space. The residents aboard the International Space Station are busy exploring how the human body and other organisms adapt to space helping NASA prepare to go to the moon by 2024.

Astronauts Christina Koch and Anne McClain split Friday checking on the Kidney Cells experiment seeking innovative treatments for kidney stones, osteoporosis and toxic chemical exposures. Counteracting the space-exacerbated symptoms is critical to the success of a long-term spaceflight to the moon and Mars.

McClain started her day with Commander Oleg Kononenko and Flight Engineers Nick Hague and Alexey Ovchinin researching space-caused head and eye pressure. The quartet tested a specialized suit, the Lower Body Negative Pressure suit, that reverses the upward flow of blood and other fluids toward an astronaut’s head. The crewmates also participated in ultrasound scans of their eyes and veins for the long-running Fluid Shifts study.

In addition, a pair of Canadian and Japanese robotic arms on the station are coordinating to swap external payloads over the weekend. Two Earth and space research facilities inside the SpaceX Dragon’s trunk are being removed for installation on the station. An older atmospheric experiment that has completed its mission will be placed back in Dragon’s trunk.

The Canadarm2 robotic arm removed the Orbiting Carbon Observatory-3 (OCO-3) from the Dragon’s unpressurized trunk. It handed off the OCO-3, a global carbon detection device, to Japan’s smaller robotic arm for installation on the Kibo lab module’s external pallet. Next, the Canadarm2 will extract and install the Space Test Program-Houston 6 hardware for space physics research on the station’s truss structure.

Finally, Japan’s robotic arm attached to Kibo will hand off the Cloud-Aerosol Transport System (CATS) to the Canadarm2 for installation in Dragon’s trunk. Before Dragon splashes down in the Pacific at the end of May, its trunk with CATS inside will separate during reentry and burn up over Earth’s atmosphere.

A SpaceX Dragon resupply ship delivered CATS in January of 2015 for robotic installation on Kibo’s external pallet. CATS successfully demonstrated low cost atmospheric monitoring techniques from the station.

The Expedition 59 crew has a light duty day today with some science work on the schedule. Meanwhile, robotics controllers are preparing to swap external payloads in the unpressurized trunk of the SpaceX Dragon cargo craft.

NASA Flight Engineer Christina Koch checked samples today as she continued exploring why pathogens become more virulent in space. Later, she set up hardware for the Kidney Cells experiment that seeks innovative treatments for humans on Earth and in space.

Astronaut Nick Hague of NASA retrieved sample trays from a materials exposure experiment brought back inside the Kibo lab module. Fellow NASA astronaut Anne McClain checked on mice being observed for changes to their immune systems in microgravity.

Two new experiments are ready for robotic extraction from the SpaceX Dragon and installation on the International Space Station starting Thursday night and into the weekend. An older experiment will be removed from the station and placed back in Dragon.

The remotely controlled Canadarm2 robotic arm will first extract the Orbiting Carbon Observatory-3 (OCO-3) from Dragon’s trunk. Japan’s robotic arm will then take hold of the OCO-3 and install the global carbon detection device on Kibo’s external pallet. The Canadarm2 will then extract and install the Space Test Program-Houston 6 hardware for space physics research on the station’s truss structure.

Finally, the Japanese robotic arm will hand off the Cloud-Aerosol Transport System (CATS) to the Canadarm2 for installation in Dragon’s trunk. CATS will burn up over Earth’s atmosphere when Dragon’s trunk separates during its reentry at the end of May. A SpaceX Dragon resupply ship delivered CATS in January of 2015 for robotic installation outside Kibo. CATS successfully demonstrated low cost atmospheric monitoring techniques from the station.

New Science Being Unpacked and Worked Aboard Orbital Lab

The SpaceX Dragon cargo craft is installed to the Harmony module’s Earth-facing port a few hours after it was captured by astronauts David Saint-Jacques and Nick Hague with the Canadarm2 robotic arm on May 6, 2019.

Six spaceships are now parked at the International Space Station and the Expedition 59 crew is working on the newest science delivered Monday. Astronauts will continue to live and work in space longer and scientists want to know how humans and a variety of other organisms adapt to support these missions.

NASA astronaut Anne McClain tended to several dozen mice delivered to the orbital lab Monday on the SpaceX Dragon cargo craft. The rodents’ immune systems are similar to humans and scientists are monitoring them to detect any changes caused microgravity.

NASA astronaut Christina Koch set up the Microgravity Science Glovebox today to begin operations with the new Micro-14 pathogen study. Microgravity can increase the virulence of pathogens and doctors are seeking to understand the process to keep space crews safe and healthy.

Koch and McClain both started Tuesday unpacking frozen biological samples from Dragon. The duo stowed the samples into different science freezers aboard the station for later analysis and experimental work.

McClain, Commander Oleg Kononenko and Flight Engineer Nick Hague also explored head and eye pressure caused by upward fluid shifts due to the effects of microgravity. The long-running human research experiment seeks to reverse the upward flow and alleviate the symptoms reported by astronauts.

This morning, just two days following its nighttime launch from the Florida coast, SpaceX’s Dragon cargo spacecraft was captured and installed on the Earth-facing side of the International Space Station’s Harmony module at 9:32 a.m. EDT.

Expedition 59 astronauts David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA successfully employed the space station’s robotic arm to grapple Dragon at 7:01 a.m., which brings the number of spaceships docked at the space station to six. Other vehicles visiting include Russia’s Progress 71 and 72 resupply ships and the Soyuz MS-11 and MS-12 crew ships, as well as Northrop Grumman’s Cygnus space freighter.

Dragon’s arrival heralds a busy week for the crew. Today, NASA astronauts Anne McClain and Christina Koch unpacked and activated time-critical experiments after completing checkout of the spacecraft. Fresh biological samples, such as kidney cells, were stowed in science freezers and incubators for later analysis. New lab mice were also quickly transferred and housed in specialized habitats to enhance research for an immune system study that aims to keep astronauts healthy for long-duration missions in space, which will become even more commonplace as our destinations extend to the Moon and beyond.

SpaceX’s 17th cargo flight to the space station under NASA’s Commercial Resupply Services contract supports dozens of new and existing investigations. NASA’s research and development work aboard the space station contributes to the agency’s deep space exploration plans, including returning astronauts to the Moon’s surface in five years.

This latest commercial cargo delivery refreshed the orbiting laboratory with 5,500 pounds of research, crew supplies and hardware.

May 6, 2019: International Space Station Configuration. Six spaceships are docked at the space station including the SpaceX Dragon, Northrop Grumman’s Cygnus space freighter and Russia’s Progress 71 and 72 resupply ships and the Soyuz MS-11 and MS-12 crew ships.

Two days after its launch from Florida, the SpaceX Dragon cargo spacecraft was installed on the Earth-facing side of the International Space Station’s Harmony module at 9:32 a.m. EDT.

The 17th contracted commercial resupply mission from SpaceX (CRS-17) delivers more than 5,500 pounds of research, crew supplies and hardware to the orbiting laboratory.

Here’s some of the science arriving at station:

Scientists are using a new technology called tissue chips, which could help predict the effectiveness of potential medicines in humans. Fluid that mimics blood can be passed through the chip to simulate blood flow, and can include drugs or toxins. In microgravity, changes occur in human health and human cells that resemble accelerated aging and disease processes. This investigation allows scientists to make observations over the course of a few weeks in microgravity rather than the months it would take in a laboratory on Earth.

The Hermes facility allows scientists to study the dusty, fragmented debris covering asteroids and moons, called regolith. Once installed by astronauts on the space station, scientists will be able to take over the experiment from Earth to study how regolith particles behave in response to long-duration exposure to microgravity, including changes to pressure, temperate and shocks from impacts and other forces. The investigations will provide insight into the formation and behavior of asteroids, comets, impact dynamics and planetary evolution.

These are just a few of the hundreds of investigations that 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. 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.

After Dragon spends approximately one month attached to the space station, the spacecraft will return to Earth with about 3,300 pounds of cargo and research.

Astronaut Commands Robotic Arm to Capture Dragon Cargo Craft

SpaceX Dragon Cargo Craft Captured
The SpaceX Dragon CRS-17 Cargo Craft captured and attached to the CanadaArm2.

While the International Space Station was traveling over the north Atlantic Ocean, astronauts David Saint-Jacques of the Canadian Space Agency and Nick Hague of NASA grappled Dragon at 7:01 a.m. EDT using the space station’s robotic arm Canadarm2.

Ground controllers will now send commands to begin the robotic installation of the spacecraft on bottom of the station’s Harmony module. NASA Television coverage of installation is scheduled to begin at 9 a.m. Watch online at www.nasa.gov/live.

The Dragon lifted off on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida Saturday, May 4 with more than 5,500 pounds of research, equipment, cargo and supplies that will support dozens of investigations aboard the orbiting laboratory.

Here’s some of the research arriving at station:

NASA’s Orbiting Carbon Observatory-3 (OCO-3) examines the complex dynamics of Earth’s atmospheric carbon cycle by collecting measurements to track variations in a specific type of atmospheric carbon dioxide. Understanding carbon sources can aid in forecasting increased atmospheric heat retention and reduce its long-term risks.

The Photobioreactor investigation aims to demonstrate how microalgae can be used together with existing life support systems on the space station to improve recycling of resources. The cultivation of microalgae for food, and as part of a life support system to generate oxygen and consume carbon dioxide, could be helpful in future long-duration exploration missions, as it could reduce the amount of consumables required from Earth.
