Free-flying robots and heart research filled the science schedule aboard the International Space Station today. The Expedition 63 crew also managed cargo activities in a pair of resupply ships and cleaned biology research gear.

Astrobee is a robotics investigation that explores the ability of a trio of cube-shaped, free-flying robots to assist crews aboard the station. Commander Chris Cassidy set up one of the autonomous robotic assistants in the afternoon for a test of its mobility and vision system. Astrobee could perform routine lab chores giving astronauts more time to conduct critical space research.

Cassidy also finalized the cleaning of a mouse habitat that housed rodents monitored for changes to their genetic expression due to microgravity. The mice have since returned to Earth aboard the last SpaceX Dragon cargo mission on April 7.

Living and working in space impacts the human body and scientists are exploring measures to ensure astronauts adapt successfully to weightlessness. How heart performance changes in space is fundamental to keeping crews healthy during long-term missions.

Cosmonauts Anatoly Ivanishin and Ivan Vagner continued a long-running Russian heart study today that utilizes the Lower Body Negative Pressure Suit. The investigation examines how the heart behaves as the specialized spacesuit prevents blood from pooling in a crewmember’s head reducing head and eye pressure.

The Russian duo then spent the afternoon transferring cargo to and from the Progress 74 and 75 space freighters. Ivanishin packed trash and old gear in the 74P which is due to complete its mission in July. Vagner unloaded new gear and supplies from the 75P which just arrived on April 25.

The three-member Expedition 63 crew aboard the International Space Station focused its attention on spacesuits and cardiac research today. The orbital residents also serviced science hardware and life support gear.

Commander Chris Cassidy worked on a pair of U.S. spacesuits in the Quest airlock today cleaning cooling loops, replacing components and checking for leaks. NASA is planning a series of spacewalks later this year to upgrade power and science systems on the orbiting lab.

Cassidy, who last served in 2013 as an Expedition 36 flight engineer, also cleaned the Veggie PONDS botany research hardware after growing lettuce and mizuna greens in the Columbus lab module. Next, he swapped batteries in the Astrobee robotic assistant then set up audio software for a hearing assessment.

Roscosmos Flight Engineers Anatoly Ivanishin and Ivan Vagner worked in the morning on a long-running study to understand how the human heart adapts to microgravity. The duo then split up for Earth observation studies and life support maintenance.

The International Space Station is looking ahead to its next cargo mission when a U.S. space freighter departs next month. The Expedition 63 crew is also working on variety of space research and Russian spacecraft activities.

The U.S. Cygnus space freighter from Northrop Grumman is being readied for its robotic release from the orbiting lab’s Unity module. Commander Chris Cassidy reviewed procedures and set up hardware that will deploy small experimental satellites from the outside of Cygnus after its departure on May 11. Cygnus will removed from Unity and released by the Canadarm2 robotic arm completing its 83-day stay at 12:10 p.m. EDT.

Cassidy also opened up the Combustion Integrated Rack for maintenance replacing components in the research device that enables safe fuel, flame and soot studies in microgravity. Afterward, the three-time station visitor logged his meals for a nutrition study then swapped batteries in an acoustic monitor that measures the sound levels aboard the station.

Cosmonauts Anatoly Ivanishin and Ivan Vagner continued unpacking and inventorying the near three tons of food, fuel and supplies delivered late last week aboard the Progress 75 resupply ship. Ivanishin also serviced a variety of Russian life support gear. Vagner checked on lighting systems and photographed the external condition of the Poisk module which hosts docked Russian spacecraft.

The International Space Station provides an orbiting research platform that benefits not only human health, but also industry and technology. Expedition 63 Commander Chris Cassidy kicked off a physics study today that explores space manufacturing.

Cassidy began his workday in the U.S. Destiny laboratory module configuring the Microgravity Science Glovebox (MSG) for the Space Fibers physics investigation. The study is using the MSG to test techniques for manufacturing fiber optic cables superior to those produced on Earth.

Gravity degrades the performance of fiber optic cables produced on Earth. Space Fibers may enable the manufacturing and commercialization of cables with greater transparency and higher transmission rates than on Earth.

The NASA commander then spent Monday afternoon on regularly scheduled maintenance for the COLBERT treadmill in the station’s Tranquility module. Cassidy greased the treadmill’s axles, tightened belts and replaced components.

In the Russian segment of the station, cosmonauts Anatoly Ivanishin and Ivan Vagner took the day off after a weekend of cargo activities. The duo welcomed the new Progress 75 cargo craft after its docking early Saturday and started unloading the nearly three tons of food, fuel and supplies.

Traveling about 260 miles over Northwestern China, south of the Mongolian border, the unpiloted Russian Progress 75 cargo ship docked at 1:12 a.m. EDT to the Zvezda Service Module on the Russian segment of the complex.

Progress 75 will remain docked at the station for more than seven months before departing in December for its deorbit in Earth’s atmosphere.

For almost 20 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. As a global endeavor, 239 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 2,800 research investigations from researchers in 108 countries.
