<\/a>An array of space biology and combustion investigations topped the microgravity research program aboard the International Space Station<\/a> on Monday. Life support work and cargo transfers also kept the Expedition 66<\/a> crew busy at the beginning of the week.<\/p>\n Living in space has been shown to impact an astronaut\u2019s vision even after returning to Earth. NASA Flight Engineers Raja Chari<\/a> and Kayla Barron<\/a> worked throughout the day studying how weightlessness affects eye structure and visual function<\/a>. The duo\u2019s research efforts may help scientists develop treatments for eye conditions in space and on Earth.<\/p>\n Astronauts are also learning how to exercise more effectively in space. The lack of gravity leads to muscle and bone loss that crews seek to avoid with daily two-hour workout sessions on the station. ESA (European Space Agency) astronaut Matthias Maurer<\/a> used the Tranquility module<\/a>\u2019s advanced resistive exercise device during the morning performing exercises such as bench presses, squats, and dead lifts. He wore a specialized suit for the EasyMotion<\/a> study that was stimulating his muscles during the workout which may improve and lessen the duration of exercise sessions in space.<\/p>\n Flames and materials burn longer and differently in microgravity and scientists and engineers use the data to keep astronauts safe in outer space. NASA Flight Engineer Mark Vande Hei<\/a> opened up the Combustion Integrated Rack<\/a> today and configured components inside the research device. He set up the rack for the Solid Fuel Ignition and Extinction<\/a> study to improve fire suppression techniques and improve spaceship safety.<\/p>\n NASA astronaut Tom Marshburn<\/a> worked throughout the day in Tranquility servicing components on the oxygen generation assembly. He collected samples from the life support device for analysis on the ground.<\/p>\n Commander Anton Shkaplerov<\/a> focused on a pair of Russian experiments on Monday. He explored ways to create a sterile research environment aboard the station then researched how the human heart adapts to space. Flight Engineer Pyotr Dubrov<\/a> unpacked medical kits delivered recently inside the ISS Progress 80<\/a> resupply ship.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0http:\/\/jscfeatures.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
