ISS - Expedition 60 Mission patch.
July 10, 2019
The Expedition 60 crew configured a variety of science hardware today monitoring the brain and radiation exposure. The orbital residents also had a steady day of safety gear checks and lab maintenance on the International Space Station.
Astronauts experience blood flow changes caused by living in microgravity that may cause lightheadedness or fainting upon return to Earth. The Cerebral Autoregulation investigation is measuring the waveforms of these blood flows to understand blood pressure regulation in space. Flight Engineer Nick Hague set up the experiment hardware this morning that may help doctors treat and prevent these symptoms.

Hague next assembled hardware for a high definition camera that will be installed outside the station on an upcoming spacewalk. He and NASA astronaut Christina Koch also installed communication cables and conducted voice checks to support the arrival of future commercial crew vehicles.

Radiation exposure is another concern for crewmembers working in space for months or years at a time. Koch handed a set of dosimeters, or radiation detectors, to Commander Alexey Ovchinin during the afternoon for installation on the Russian side of the orbiting lab. Several studies are monitoring neutron radiation and the variation in the radiation environment as the station orbits Earth.
Koch started her morning inspecting breathing masks and fire extinguishers. She checked the emergency equipment for correct pressure measurements and any signs of physical damage on hoses and bottles. Ovchinin continued the replacement of more Russian life support system components during his morning.
