Samples of spacesuit material will be flown on the Mars 2020 mission to study show they might degrade in the Martian environment.

Robotics, combustion and human research were the primary focus of today’s science schedule aboard the International Space Station. The Expedition 59 crewmembers also checked out U.S. spacesuits and specialized pants designed to counteract some of the effects of living in microgravity.
Astrobee, a tiny cube-shaped free-flying robotic assistant, is being tested aboard the orbital lab for its sighting and motion abilities. Flight Engineer David Saint-Jacques of the Canadian Space Agency (CSA) set up Astrobee for more mobility tests today inside the Japanese Kibo laboratory module. The device may support routine maintenance tasks and lab monitoring capabilities. Northrop Grumman’s Cygnus space freighter delivered Astrobee to the station April 19.
The safe observation of how fuels and materials burn in microgravity takes place in the space station’s Combustion Integrated Rack (CIR). The research takes place in the U.S. Destiny laboratory module and may help engineers design more fuel-efficient spacecraft engines and safer, less flammable environments. NASA astronaut Christina Koch replaced a burner and igniter tip in the CIR to maintain continuing combustion research operations.
Flight Engineer Anne McClain of NASA attached cuffs to her legs and sensors to her chest for a series of blood pressure checks and ultrasound scans today. The Vascular Echo biomedical study from CSA, ongoing since March 2015, analyzes an astronaut’s cardiovascular system for conditions such as arterial stiffness.
U.S. spacesuits continue to be serviced after a set of three spacewalks that took place earlier this year. Astronaut Nick Hague cleaned the suit’s cooling loops, cycled their pressure valves and tested water samples inside the Quest airlock where U.S. spacewalks are staged.
Cosmonauts Oleg Kononenko and Alexey Ovchinin have been training this week to use the Lower Body Negative Pressure suit. The Russian suit, also known as Chibis, counteracts the upward fluid shifts in the human body caused by microgravity. This may alleviate the head and eye pressure reported by astronauts. An easily recognizable symptom of these fluid shifts that all crews experience is “puffy face.”

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.
