The outside of the International Space Station is a harsh environment but scientists are taking advantage of the extreme conditions to conduct advanced space research. Astronauts are also researching what happens to a variety of organisms living for months at a time inside a spacecraft as NASA prepares for longer missions farther out into space.

The fifth and final external materials experiment (MISSE) delivered by the latest SpaceX Dragon resupply ship was activated outside the orbital lab today. Robotics engineers operating the Canadarm2 and Dextre extracted and installed the MISSE canisters one by one from Dragon’s trunk to areas on the station. The canisters were then remotely opened exposing a variety of materials to the vacuum of space to help engineers design safer and stronger spacecraft systems.

Back inside the orbital lab, Flight Engineer Scott Tingle of NASA harvested and photographed plants for the APEX-06 study today. The botanical samples collected from the VEGGIE facility were later processed and stowed in a science freezer for return to Earth inside the Dragon cargo craft. They will be analyzed after being quickly shipped to scientists at NASA and the University of Wisconsin.

NASA Flight Engineers Ricky Arnold and Drew Feustel once again partnered up and collected their blood and urine samples today for more biomedical experiments. Researchers are analyzing the samples as they continuously study how the human body adapts to extended periods of weightlessness. Results will help doctors provide therapies to maintain the health of astronauts in space and humans on Earth.

Mice are also being observed on the space station so scientists can detect the chemical signals that lead to weakened bones and muscles. Japanese astronaut Norishige Kanai drew more blood samples from the rodents today and wrapped up a week-long run of the Mouse Stress Defense experiment. The blood samples will be processed in a centrifuge, stowed in biological science freezer then returned to Earth inside Dragon for analysis on Earth.

Station Biomedical and Exercise Studies Impact Health on Earth and in Space

Station Biomedical and Exercise Studies Impact Health on Earth and in Space

Doha, the capital city of Qatar
Doha, the capital city of Qatar, was photographed as the space station orbited over the northeastern coast of the Arabian Peninsula.

Biomedical research to improve health on Earth and in space dominated today’s science activities aboard the International Space Station. The Expedition 55 crew is helping scientists from around the world understand how life shaped by gravity adapts to living in outer space.

NASA astronauts Ricky Arnold and Drew Feustel joined forces today collecting and stowing their blood samples in a science freezer for a pair of human research studies. The samples will be analyzed later to detect the chemical responses and physiological changes that take place in the human body during a spaceflight mission.

Blood samples were also drawn from mice as Japanese astronaut Norishige Kanai continued his week-long research activities for the Mouse Stress Defense experiment. Those samples will be processed in centrifuge, stowed in a freezer then analyzed to detect the processes that lead to muscle and bone loss in microgravity. Astronauts could benefit from the results and stay healthier on longer missions farther into space.

Exercise is a very important contributor to maintaining stronger bones and muscles in space. However, exercise devices are bulky and can impact spacecraft habitability. Arnold tested a newer, smaller device today called the Miniature Exercise Device-2 that provides a range of motion and resistance workouts while maximizing habitable spacecraft volume.

Lab Tests and Life Science as Station Orbits Higher Today

Lab Tests and Life Science as Station Orbits Higher Today

Mexico, Baja California and the southern coast of the state of California
Mexico, Baja California and the southern coast of the state of California are pictured as the International Space Station orbited above the Pacific Ocean.

A docked Russian cargo craft automatically fired its engines this morning boosting the International Space Station’s altitude a little higher. During the rest of the day, the Expedition 55 crew supported life science and swapped out station hardware.

Russia’s Progress 69 resupply ship docked to the Zvezda service module fired its thrusters boosting the station’s orbit today. The two-minute, six-second burn establishes the correct orbit when three crew members undock and land in June and a two-orbit rendezvous capability for the Progress 70P resupply craft when it launches in July.

NASA crewmates Scott Tingle, Ricky Arnold and Drew Feustel became lab assistants today as they collected and stowed their own blood, urine and saliva samples in a science freezer. Two long-running human research experiments, Biochemical Profile and Repository, are basing their results on the analysis of these samples helping scientists understand how microgravity impacts the human body.

Tingle later tested the Miniature Exercise Device-2 for providing a range of motion and resistance exercise while taking up less space aboard the station. Feustel installed new firewall gear in the Harmony module before replacing manifold bottles in the Combustion Integrated Rack. Arnold worked with commercial science hardware then processed samples for a protein crystal growth student experiment.

Mice are being observed on the orbital lab today to understand the physiological signals that lead to muscle and bone loss in space. Norishige Kanai from the Japan Aerospace Exploration Agency collected blood samples from the mice to be processed, analyzed and stowed in a science freezer. Scientists are studying the effectiveness of a drug therapy to prevent those stresses and signals that cause weakened bones and muscles.

Expedition 55 Flight Engineer Drew Feustel of NASA is inside the Japanese Kibo laboratory module talking to dignitaries on Earth, including university officials, musicians and scientists, during an educational event that took place at Queen’s University in Kingston, Ontario.

The International Space Station is set to raise its orbit Wednesday ahead of upcoming cargo and crew missions. Meanwhile, the six Expedition 55 crew members are staying busy today with medical tests, cargo work and lab maintenance.

The space station will increase its altitude slightly when a docked Russian cargo craft automatically fires its engines for two minutes and six seconds early Wednesday. The maneuver will establish the correct orbit for the landing of three crew members in June and a two-orbit rendezvous capability for the next Russian Progress resupply craft in July.

Flight Engineer Scott Tingle collected and stowed his own urine sample today for a pair of biomedical studies examining the effects of spaceflight on the human body. The U.S. Navy pilot also continued operations for the Metabolic Tracking (MT) experiment that observes how human tissue samples are impacted by a specific drug compound.

Expedition 55-56 crewmates Drew Feustel and Ricky Arnold checked each other’s eyes today using optical coherence tomography gear inside the Harmony module. Feustel also installed and checked the station’s first updated printer since 2000 before wrapping up his day unloading cargo from the SpaceX Dragon cargo craft. Arnold finally collected water samples and changed out a cartridge as part of preventative maintenance on a U.S. oxygen generator.

Astronaut Norishige Kanai from Japan continued more upkeep work for the Mouse Stress Defense experiment that is exploring the causes of muscle and bone loss in space. The busy flight engineer later assisted his fellow crew members unloading SpaceX cargo before injecting human tissue samples with a drug compound for the MT study.

Medicine and Mice Research All Week Long for Astro-Scientists

The Bahamas
The clear blue waters surrounding the islands of the Bahamas were pictured April 4, 2018 from an Expedition 55 crew member aboard the space station.

Scientists on the ground and in space this week are exploring a wide variety of phenomena affecting humans living in space. The ongoing life science aboard the International Space Station is designed to improve astronauts’ health in space and benefit people on Earth.

Medicine plays an important role in an astronaut’s health and doctors want to know more about how drug therapies work in space. NASA Flight Engineer Drew Feustel supported the medicine research today and injected human tissue samples with a drug compound for the Metabolic Tracking study. Those samples will be incubated then frozen before returning to Earth to be analyzed. Results may help the pharmaceutical industry design better, cheaper drugs for humans on Earth and in space.

Japanese astronaut Norishige Kanai is tending to mice today, cleaning their habitats and preparing for a week-long run of the Mouse Stress Defense experiment. The Expedition 55 crew and doctors on Earth are observing the mice to understand the processes leading to muscle and bone loss in microgravity. Researchers are testing therapies that may prevent the physiological signals and stresses in space that lead to a weakened musculoskeletal system.

Other important space research taking place throughout the week will look at how plants grow off Earth possibly sustaining future crews and improving Earth agriculture. The crew will also test the new Miniature Exercise Device-2 for providing a range of motion and resistance exercise while taking up less space aboard the station.

More external cargo operations took place outside the SpaceX Dragon resupply ship over the weekend. Robotics controllers remotely operating the Canadarm2 stowed a failed pump flow control sub-assembly (PFCS) in Dragon’s trunk ahead of a May spacewalk. That spacewalk will see two astronauts work outside the station to relocate a series of spare sub-assemblies for functional testing.
