NASA astronaut Chris Williams will recap his recent eight-month mission aboard the International Space Station during a news conference at 2:45 p.m. EDT Tuesday, Aug. 4, from the agency’s Johnson Space Center in Houston.
NASA will stream this event live through a variety of platforms. Learn where to watch online:
United States-based media interested in attending in person must contact the NASA Johnson newsroom no later than 5 p.m., Friday, July 31, at jsccommu@mail.nasa.gov.
Media wishing to participate by phone must contact the Johnson newsroom no later than two hours before the start of the event. To ask a question by phone, media must dial into the news conference no later than 15 minutes prior to the start of the call. NASA’s media accreditation policy is available online.
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.
During 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.
