Flying robots and ultrasound eye scans were the top science activities aboard the International Space Station today. The Expedition 63 crew also serviced a variety of lab hardware and tested a wearable health monitor.
Free-flying robotic assistants called AstroBees were checked out as Commander Chris Cassidy once again tested their ability to autonomously navigate the orbiting lab. The veteran astronaut then shut down and docked the small cube-shaped devices inside the Kibo laboratory module from JAXA (Japan Aerospace Exploration Agency).
Students on Earth will soon get a chance to “test-drive” the Astrobees in a competition for the best program to control the robotic devices. Researchers are also exploring the Astrobees’ potential to perform routine station duties so the crew has more time for critical science.
Cassidy also tackled more mundane tasks during the morning as he worked on space plumbing duties in the Kibo lab. The commander wiped leaking water and inspected plumbing connections in Kibo’s Water Recovery System.
In the afternoon, Cassidy had his eyes scanned by three-time station Flight Engineer Anatoly Ivanishin using an ultrasound device. The ultrasound exam, with real-time inputs from doctors on the ground, looks at the health of the retina, cornea and optic nerve.
Ivanishin started his workday swapping fuel bottles inside the Combustion Integrated Rack which enables safe studies of fuels, flames and soot in microgravity. First-time space flyer Ivan Vagner worked during the morning on Russian power supply systems before servicing water tanks in the Zvezda service module. Just after lunchtime, Vagner attached the Holter Monitor, a non-invasive medical device, to his chest that will measure his heart’s electrical activity.
