In early January 2019 the aerospace industry's official from Russia said that Soyuz spacecraft will perform record-long missions to the International Space Station (ISS), lasting for seven months.
"Soyuz MS-12 is to be launched on March 1 and is to land on October 3 with the mission duration of 216 days. Soyuz MS-13 is launched on July 6 and lands on February 6, 2020, with the mission duration of 215 days," the official said.
Soyuz MS-12 is expected to deliver a crew comprising a Russian cosmonaut, a US astronaut and the first ever astronaut from the United Arab Emirates (UAE) to the space station.
