This afternoon, a Russian Soyuz rocket will launch three crew members to the International Space Station. The mission includes NASA astronaut Jeff Williams and two Russian cosmonauts: Oleg Skripochka and Alexey Ovchini.
These three will be replacing the three astronauts who left the ISS on March 1, including Scott Kelly and Mikhail Kornienko. Jeff Williams, who is set to stay aboard the ISS for six months, will break the record set by Kelly for most days spent in space.
After Kelly's recent One-Year Mission, he spent a cumulative total of 520 days in space. Williams is set to spend a total of 534 days in space, by the end of this mission. You can watch the launch live on NASA TV, when coverage begins at 4:30PM ET.
