A trio of studies taking place today aboard the International Space Station explored a potential cancer therapy, researched human reproduction and observed protein crystals. Eye exams were also on the schedule to understand how microgravity impacts vision.

NASA astronaut Serena Auñón-Chancellor started her morning peering at endothelial cells through a microscope for the AngieX Cancer Therapy study. Afterward, she moved on to the Micro-11 investigation examining more biological samples in a microscope to gain fundamental data about successful reproduction in space.

Alexander Gerst, of the European Space Agency, contributed to pharmaceutical research during the afternoon stowing protein molecules in a science freezer. Microgravity enables the growth of high quality protein crystals revealing structures and properties that could improve disease-fighting therapies on Earth.

Gerst first started his day scanning NASA astronaut Ricky Arnold’s for eyes using Optical Coherence Tomography, a light imaging technique analogous to ultrasound. The data helps doctors understand how the weightless environment of microgravity impacts vision so mission controllers can plan safer spaceflight missions.

Finally, the SpaceX Dragon space freighter is being packed for its return to Earth on Aug. 3. Arnold and Commander Drew Feustel took turns today loading Dragon with station hardware and research samples for retrieval and analysis on Earth.

The International Space Station got an orbital boost today to position itself for a crew swap taking place later this year. Inside the lab complex, the current residents spent their time today exploring a diversity of phenomena impacted by long-term exposure to microgravity.

A docked Russian Progress 69 resupply ship fired its engines this morning slightly increasing the space station’s orbital altitude to enable the departure and arrival of a pair of Soyuz crew ships this autumn. Three Expedition 56 crew members will return to Earth Oct. 4 inside the Soyuz MS-08 spacecraft. They will be replaced a week later by two new Expedition 57 crew members when they dock inside the Soyuz MS-10 spacecraft.

NASA astronauts Drew Feustel and Serena Auñón-Chancellor continued a second week of research operations to gain fundamental data about fertility in space. The duo examined biological samples in a microscope and stowed them in a science freezer for later analysis. The Micro-11 study is exploring the possibility of human reproduction in space including ways to address aging problems on Earth.

Alexander Gerst, of the European Space Agency, explored the sedimentary properties of quartz and clay particles. The German astronaut mixed quartz and clay samples suspended in a liquid for photographic and video downlink to scientists on Earth. Observations can help guide future geological studies of unexplored planets and improve petroleum exploration here on Earth.

Expedition 56 Flight Engineer Ricky Arnold of NASA split his time working on a variety of science gear that examines different microscopic properties. He set up Aerosol Samplers in the Harmony and Tranquility modules to collect airborne particles in the station’s air cabin for analysis. Arnold later stowed a Biomolecule Sequencer he used this month to sequence DNA extracted from microbes living on space station surfaces.

Expedition 56 crewmembers collaborated for the second day in a row studying how living in microgravity impacts rodents. The space research onboard the International Space Station is helping doctors keep astronauts healthy in space and while developing advanced therapies for humans on Earth.

Rodent research, and a variety of other life science studies observing organisms in space, has been ongoing for years aboard the orbital laboratory. The latest experiment, Rodent Research-7, looks at how microbes affect the physiology of mice. The mice and research gear were delivered July 2 aboard the SpaceX Dragon. Scientists are seeking to understand how microbes affect the gastrointestinal, immune, metabolic, circadian, and sleep systems.

Astronauts Drew Feustel and Alexander Gerst collected blood samples and measured the bone mass of the rodents today. Flight Engineers Ricky Arnold and Serena Auñón-Chancellor contributed to the research work stowing biological samples in science freezers. The samples will be returned to Earth Aug. 3 when Dragon splashes down in the Pacific Ocean for retrieval and analysis by scientists on Earth.

Life science took precedence today aboard the International Space Station as the crew explored how microgravity impacts rodent physiology. The space research can help scientists improve astronaut health and treat humans on Earth.

Four Expedition 56 crew members worked together throughout the day examining mice for the Rodent Research-7 study. The experiment observes how microbes affect the gastrointestinal, immune, metabolic, circadian, and sleep systems. Results may help doctors implement programs to keep astronauts healthy on deep space missions. Patients on Earth may also benefit from newer advanced therapies that treat internal disorders.

Commander Drew Feustel joined Flight Engineers Serena Auñón-Chancellor, Ricky Arnold and Alexander Gerst for the rodent study on Tuesday. The orbital lab researchers examined bone structure, collected blood samples and processed and stowed biological samples in science freezers.

Those samples will be returned to Earth inside the SpaceX Dragon cargo craft Aug. 3 for analysis on Earth. Dragon will be packed with station hardware and research gear when it splashes down in the Pacific Ocean. It will be retrieved by SpaceX and NASA personnel for examination by engineers and scientists.

The Expedition 56 crew members continued their work Friday on more fertility research and microbe studies aboard the International Space Station. They also worked on science gear for a study seeking advanced therapies for diseases such as Alzheimer’s and diabetes.

Commander Drew Feustel and Flight Engineer Serena Auñón-Chancellor examined biological samples for the Micro-11 fertility study. They looked at the samples through a microscope which were later stowed in a science freezer. The experiment seeks to determine if human reproduction would be possible off the Earth.

Feustel also spent some time in the morning working on the Amyloid experiment to help doctors develop advanced treatments for Alzheimer’s disease and diabetes. He collected amyloid fibril samples from the Cell Biology Experiment Facility and stowed them in a science freezer for spectroscopy and microscopic analysis back on Earth.

European astronaut Alexander Gerst and NASA astronaut Ricky Arnold were sampling the station’s atmosphere and surfaces for a pair of microbe investigations today. Gerst collected microbe samples and stowed them in a freezer for molecular analysis on Earth to identify potential pathogens on the station. Arnold processed microbial DNA using the Biomolecule Sequencer, a device that enables DNA sequencing in microgravity, to identify microbes able to survive in microgravity.
