NASA astronaut Christina Koch sets up Fiber Optic Production, an investigation to create optical fibers in microgravity that may exhibit superior quality to those produced on Earth. Image Credit: NASAThe crew of Expedition 59 was hard at work today setting up a litany of science experiments and conducting maintenance to the International Space Station that will help further NASA’s goal of returning to the Moon.
Some unplanned maintenance to replace a failed Main Bus Switching Unit-3 (MBSU), which was completed this morning by robotics ground controllers through the use of the space station’s Canadarm2 and Dextre, also known as the Special Purpose Dextrous Manipulator (SPDM), restored the orbiting laboratory to a nominal power configuration. Ordinarily, this intensive procedure would have required the station residents to perform an emergency spacewalk. However, swapping out the MSBU entirely through robotics work demonstrated that some of the capabilities explorers will need for the Moon and destinations beyond are being tested right now in low-Earth orbit.
Meanwhile, within the space station, Flight Engineers Anne McClain and Christina Koch prepped investigations vital to the next generation of space explorers. McClain spent time setting up mass measurement hardware for Rodent Research-12, which will examine the effects of ...
