The crew aboard the International Space Station continued exploring the numerous ways living in space affects the human body and other organisms. The station residents also participated in an emergency simulation exercise.
Commander Jeff Williams and Flight Engineer Oleg Skripochka this week are exploring fluid shifts from an astronaut’s lower body to the upper body during long-term space missions. This phenomena that occurs in microgravity increases pressure on a crew member’s brain and eye structure potentially affecting vision.
NASA astronaut Kate Rubins relocated an incubator that houses Heart Cells research samples from one science rack to another. Those samples will be analyzed on Earth when the SpaceX Dragon returns the research at the end of August. Japanese astronaut Takuya Onishi continued the upkeep of an experiment that is researching genetic alteration in mice and their offspring due to the microgravity environment.
All six Expedition 48 crew members joined each other in the afternoon to practice their response to an unlikely emergency situation. The astronauts and cosmonauts practiced communication and coordination in conjunction with Houston and Moscow control centers in response to emergency simulators.

The six-member Expedition 48 crew participated in a series of experiments today exploring how living in space affects the human body. Also, a set of bowling ball-sized experimental satellites was set up for a student contest.
Scientists are sampling crew respiration today to understand the health impacts of living in the International Space Station’s closed atmosphere. Astronauts Kate Rubins and Takuya Onishi used a portable device measuring the amount of nitrogen that is exhaled and diffused in the blood.
Onishi also collected biological samples for the Multi-Omics study that is observing how the human immune system functions in space. Commander Jeff Williams set up hardware to research how upper body fluid shifts affect a crew member’s head and eye structure.
Williams then joined cosmonaut Oleg Skripochka configuring tiny internal satellites for a planned high school student competition next week. The contest, known as SPHERES Zero Robotics, uses student written algorithms to control small SPHERES satellites performing functions similar to a space mission.

The Expedition 48 crew continued researching how living in space affects the eyes and the brain today. Two NASA astronauts also are getting ready for a mid-August spacewalk to install a new docking port.
Commander Jeff Williams and cosmonaut Alexey Ovchinin participated in the Fluid Shifts experiment today. They used an ultrasound scan and a tonometer to monitor the fluid pressure in an astronaut’s head and eyes. Microgravity tends to shift fluids to the upper body increasing pressure in the head with some astronauts experiencing vision problems.
Williams then joined Flight Engineer Kate Rubins in the U.S. Quest airlock to resize a pair of spacesuits. The duo are scheduled for an Aug. 19 spacewalk to install an International Docking Adapter on the Harmony module.
The adapter will be removed from the SpaceX Dragon Aug. 17 during a six-hour robotic maneuver to place it in installation position. The adapters will enable future commercial crew vehicles from Boeing and SpaceX to dock to the International Space Station.
New science unloaded from the latest SpaceX Dragon to visit the International Space Station is under way. The variety of new and ongoing space research is designed to benefit life on Earth and astronauts on long duration missions.
Astronaut Kate Rubins, a biological researcher on Earth, is lifting her science expertise to new heights today setting up a microscope in the U.S. Destiny laboratory module. The new microscope will observe heart cells to help doctors understand how the human heart adapts in space and improve crew health.
Japanese astronaut Takuya Onishi checked the habitat for the Mouse Epigenetics experiment today. That study is researching how microgravity alters the gene expression in mice and DNA in their offspring.
Commander Jeff Williams joined cosmonaut Alexey Ovchinin for ultrasound scans today to investigate how fluids shift from the lower body to the upper body. The study is exploring how these fluid shifts affect fluid pressure in an astronaut’s head and eyes potentially affecting vision.
Cosmonauts Oleg Skripochka and Anatoly Ivanishin partnered together for a study of the upper body that observes changes in the cardiovascular and respiratory systems. The research explores breathing and blood pressure in microgravity to maintain the health of crews living in space.
Expedition 48 is moving ahead with preparations for an upcoming spacewalk. New science also is under way aboard the International Space Station after being delivered last week.
A new U.S. spacesuit was unpacked from inside Dragon and will be used during an August spacewalk to install a Commercial Crew docking port. An older U.S. spacesuit will be returned to Earth inside the Dragon for refurbishment.
Housed inside the trunk of the Dragon space freighter is the International Docking Adapter. The new docking adapter will be installed to the Harmony module during next month’s spacewalk. It will enable future crew spacecraft from Boeing and SpaceX to dock to the station.
The new Heart Cells study got under way last week to observe how heart muscle tissue adapts to microgravity. Another life science experiment, Mouse Epigenetics, is being set up this week to explore how living in space affects gene expression. The hardware and mice for both experiments were delivered last week inside Dragon.
The Expedition 48 crew is beginning work on new science delivered aboard the SpaceX Dragon space freighter. More cargo is also being unloaded from the new Russian Progress 64 resupply ship.
NASA astronaut Kate Rubins has begun work on the new Heart Cells study that will observe how heart muscle tissue adapts to microgravity. Rubins also partnered with Japanese astronaut Takuya Onishi for the Body Measures experiment that researches how the body shape changes in outer space. Onishi later setup Mouse Epigenetics gear that will enable research into genetic expression and DNA in mice and their offspring.
Commander Jeff Williams worked on plumbing activities in the U.S. segment of the International Space Station. He also worked on biological research hardware before moving on to cargo transfers from the new Dragon cargo craft.
Cosmonauts Alexey Ovchinin and Anatoly Ivanishin are unloading gear from the new Progress cargo craft today. The duo also looked at cell cultures for the Kaskad study. Fellow cosmonaut Oleg Skripochka worked on Russian maintenance tasks and joined Ovchinin for the Korrektsiya bone loss study.
The SpaceX Dragon is chasing the International Space Station and the Expedition 48 crew is getting ready for its approach and capture Wednesday morning. This follows Monday evening’s rendezvous and docking of the Progress 64 resupply ship from Roscosmos.
Dragon is delivering several science experiments including a DNA sequencing study and the Heart Cells investigation. The private space freighter is also carrying one of two International Docking Adapters. The adapters will enable future crewed vehicles from Boeing and SpaceX to dock to the space station.
The research, hardware and other supplies stowed inside Dragon total nearly 5,000 pounds. Dragon will be robotically attached to the Harmony module after astronauts Jeff Williams and Kate Rubins capture it with the 57.7 foot long Canadarm2. This will be the second cargo mission to arrive at the station in less than two days.
The Progress arrival Monday night brought more than three tons of food, fuel and supplies for the Expedition 48 crew. Progress automatically docked to the Pirs docking compartment after launching Saturday evening from Kazakhstan.
Williams, Rubins and Flight Engineer Takuya Onishi prepared for the Dragon’s arrival on Tuesday and participated in a variety of research and maintenance activities.
