NASA astronauts Christina Koch and Andrew Morgan are venturing for the first spacewalk of the Expedition 61 outside the International Space Station (ISS) to install new lithium-ion batteries delivered last week aboard Japan’s HTV-8 cargo aircraft. Koch has reached the 200-day milestone today in her extended mission aboard the space station. Her stay will go up to 300 days and eventually set a record for the longest single spaceflight by a woman, eclipsing the record of 289 days set by former NASA astronaut Peggy Whitson in 2016-17.
