A pair of astronauts tried on U.S. spacesuits this morning ahead of a spacewalk next week. Afterward, the crew explored heart cells, fluid pressure in the head and the eyes and the composition of meteors.
NASA astronauts Jeff Williams and Kate Rubins are due to work outside the International Space Station on Aug. 19 for 6.5 hours. The duo tried on the spacesuits today they will wear during the spacewalk to complete the installation of the first of two International Docking Adapters to the Harmony module. Commercial Crew vehicles are being developed by Boeing and SpaceX that will dock to the new adapters in the future.
Rubins then moved on to observing heart cells with a specialized microscope. The heart cells are derived from stem cells that were manufactured from human skin cells.
Williams joined cosmonaut Anatoly Ivanishin for ultrasound scans and vision checks. That work was part of the Fluid Shifts study that is exploring how the lack of gravity influences head pressure and eye shape possibly affecting an astronaut’s vision.
Japanese astronaut Takuya Onishi replaced a hard drive on a laptop computer that collects data on the composition of meteors entering Earth’s atmosphere. Cosmonauts Oleg Skripochka and Alexey Ovchinin participated in a study that seeks to improve the ability of a crew member to pilot a spacecraft.
The Expedition 48 crew continued more eye exams and ongoing research to understand how microgravity shifts body fluids toward the upper body. Two NASA astronauts also checked out U.S. spacesuit safety gear and tools.
All six crew members participated in variety of eye exams throughout the day. Some of the eye checks also coincided with the Fluid Shifts study. That research observes how fluid pressure in space affects a crew member’s head and eyes, possibly affecting vision.
Commander Jeff Williams and Flight Engineer Kate Rubins are getting ready for an Aug. 19 spacewalk to install an International Docking Adapter. The docking port, delivered by the SpaceX Dragon last month, will enable future commercial crew spacecraft from Boeing and SpaceX dock to the station. The spacewalkers checked their spacesuit safety jetpacks they would use in the unlikely event they became separated from the International Space Station.

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.
NASA Television will provide live coverage of the departure of Orbital ATK’s Cygnus cargo spacecraft from the International Space Station beginning at 9 a.m. EDT on Tuesday, June 14. Release from the space station’s Canadarm2 is scheduled for 9:30 a.m.
About five hours after departure, the Saffire-I experiment will take place onboard the uncrewed cargo craft. Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions.
A new wave of Cubesats was shot into space today for a wide variety of Earth observations and communications research. The crew also explored life science and worked on high-flying plumbing tasks.
Today’s set of Cubesat deployments from the Kibo lab module’s airlock was the second of three consecutive days of deployment operations. The Dove Satellites deployed today are built and operated by Planet Labs Inc. and take images of Earth for several humanitarian and environmental applications.
Back inside the International Space Station, the crew took bone density measurements in mice in the Microgravity Science Glovebox to learn how living in space affects muscles and bones. The Rodent Research-3 experiment is testing an antibody used on Earth that may prevent muscle and bone wasting in space possibly improving the health of astronauts and humans on the ground.
The Waste and Hygiene Compartment (WHC), one of the orbital lab’s restrooms, experienced a problem last week requiring some part replacement work. That maintenance work coincided with the installation of a new Advanced Recycle Filter Tank Assembly in support of transition to new pre-treat formula which aims to increase the amount of urine that is recycled into potable water.
The International Space Station completed its 100,000th orbit early this morning after its first component, the Zarya cargo module, launched Nov. 20, 1998. That is over 2.6 billion miles traveled, nearly the distance from Earth to Neptune (2.9 billion miles), or ten round trips from Mars to Earth.
A few hours after the station reached this morning’s orbital benchmark, a several types of Cubesats were deployed from the Kibo lab module’s airlock. More Cubesats will deployed through Wednesday contributing to a wide variety of research designed by students and scientists.
