SUMMARY:NASA Astronaut Chris Williams Post-ISS Mission Debrief
DESCRIPTION:2:45 pm EDT from Johnson Space Center\, NASA astronaut Chris Williams will recap his recent eight-month mission aboard the International Space Station. Williams returned to Earth on July 26\, after logging 241 days as an Expedition 73/74 flight engineer during his first spaceflight. He returned along with Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev\, completing 3\,856 orbits of the Earth over the course of their more than 102-million-mile journey. They also saw the arrival of six visiting spacecraft and the departure of eight. \nDuring his mission\, Williams supported a wide range of scientific investigations and technology demonstrations. He helped advance research for new cancer treatments and improved in-space manufacturing of materials used in high-performance computers and electronics. Williams also completed two spacewalks to prep for space station power system upgrades and to replace a faulty joint on the Canadarm2 robotic arm. The crew’s work aboard the space station helps improve life on Earth and prepare for future human missions to the Moon and Mars. \n
