Crew Preps for Split, Studies Space Effects on Human Body

The Expedition 59 crew will split up later this month when three International Space Station residents return to Earth. The other three crewmembers today practiced evacuating the orbiting lab in the unlikely event of an emergency.

Station Commander Oleg Kononenko will depart home with Flight Engineers Anne McClain and David Saint-Jacques inside the Soyuz MS-11 crew ship on June 24. The trio have been living in space since Dec. 3 and will have orbited Earth for 204 days after landing in Kazakhstan. The commander spent the day Thursday collecting cargo for stowage and readying the homebound Soyuz.

The three crewmembers that are staying behind conducted an emergency drill during the afternoon. Flight Engineers Alexey Ovchinin, Christina Koch and Nick Hague conducted an emergency simulation and rehearsed quickly entering their Soyuz lifeboat, undocking and descending to Earth.

Human research continued full speed ahead today to help doctors keep astronauts healthy in space. McClain and Hague once again collected their breath samples for the Airway Monitoring study. The experiment studies airway inflammation as crewmembers on space missions are at an increased risk of breathing free-floating dust and particles due to the microgravity environment. Results could improve the mission environment and optimize crew health for successful long-term missions. Saint-Jacques participated in ultrasound scans of his neck, gut, heart and leg throughout the day. The ground-assisted Vascular Echo scans give flight surgeons insight into an astronaut’s cardiovascular condition.

The crew also worked on robotics power cables and the installation of a small satellite deployer. Koch installed cables in the Unity module during the morning to provide backup power for the Canadarm2 robotic arm. McClain spent the majority of her day in Japan’s Kibo laboratory module installing hardware that will soon eject a set of CubeSats outside the station for research in Earth orbit.

The two cosmonauts, Kononenko and Ovchinin, spent some time in the morning exploring ways to counteract the effects of microgravity. The duo tested a unique suit that draws body fluids towards the feet to minimize head and eye pressure.

Station Biomedical and Behavioral Studies Informing Future Missions

The Expedition 59 crew collected blood and breath samples today to test new biomedical gear and protect future astronauts going to the Moon and Mars. The orbital residents also participated in a pair of behavioral studies aboard the International Space Station.

The five-year-old Airway Monitoring study from the European Space Agency is analyzing exhaled Nitric Oxide in an astronaut’s breath to detect dust and other toxins. NASA astronauts Nick Hague and Anne McClain collected a series of breath samples for the health study today in the U.S. Destiny laboratory module. Future lunar or Martian astronauts could inhale dust collected in their habitats or on their spacesuits potentially inflaming their airways. Monitoring a crewmember’s airways could improve the mission environment and optimize crew health for a successful long-term mission.

David Saint-Jacques collected blood samples during the morning and placed them inside the Bio-Analyzer from the Canadian Space Agency. The new device supports the Life Science Research System and rapidly analyzes molecular and cellular properties of biomedical samples aboard the space station.

Saint-Jacques and McClain later took turns jotting down their impressions of living in a confined space environment separated from family and friends. Crew inputs from the Behavioral Core Measures study could provide insights to doctors seeking a standardized method to measure and assess behavioral health in astronauts.

Flight Engineer Christina Koch started her day taking tests for the Standard Measures study that observes a variety of cognitive functions such as memory, attention and orientation. Later, she checked out spacesuit gloves then stowed hardware from the Capillary Structures life support systems study.

Health Checkups, Station Gardening and Space Science Fill Tuesday

Four Expedition 59 astronauts underwent periodic health checkups and regularly scheduled eye scans today. The International Space Station residents also had time set aside for space gardening, furnace work, crew ship packing and radiation checks.

Astronauts Anne McClain and Christina Koch started Tuesday morning checking each other’s vital signs including temperature, blood pressure, pulse and respiratory rate. They were followed shortly afterward by Flight Engineers Nick Hague and David Saint-Jacques.

In the afternoon, the Koch and Hague swapped roles as Crew Medical Officer (CMO) and used an ultrasound device to scan each other’s eyes. Saint-Jacques then took over as CMO and activated the optical coherence tomography gear to image the retinas of Koch and Hague. The ongoing eye exams help flight surgeons understand how long-term weightlessness affects vision and the shape of the eye.

McClain and Koch spent a few moments in the middle of their eye checks today thinning and watering plants for the Veg-04 botany experiment. The research takes place in a specialized greenhouse and explores the feasibility of a continuous fresh food production system in Europe’s Columbus laboratory module.

After the vital sign checks, Hague partnered up with McClain to reconfigure and install an advanced furnace in the Japanese Kibo laboratory module. The Electrostatic Levitation Furnace enables the observation of thermophysical properties and the synthesis of high temperature materials on the station.

Commander Oleg Kononenko continued readying the Soyuz MS-11 crew ship for its departure June 24 carrying him, McClain and Saint-Jacques back to Earth. Flight Engineer Alexey Ovchinin collected radiation sensors from the station’s U.S. side and downloaded measurement readings. The Russian duo also trained to operate a unique suit that counteracts microgravity and draws body fluids towards the feet to minimize head pressure.
