The Soyuz MS (Russian: Союз МС; GRAU: 11F732A48) is the latest version of the Russian Soyuz spacecraft series, first launched in 2016. The "MS" stands for "modernized systems," referring to improvements in navigation, communications, and onboard systems over the Soyuz TMA-M series. Developed and manufactured by Energia, it is operated by Roscosmos for human spaceflight missions to the International Space Station (ISS).
Soyuz MS-01, the first flight of the series, launched on 7 July 2016 and docked with the ISS two days later following a checkout phase to validate the new systems. The mission lasted 113 days, concluding with a landing on the Kazakh Steppe on 30 October 2016.
The Soyuz MS spacecraft has been involved in one in-flight abort. During the launch of Soyuz MS-10 in October 2018, a booster separation failure on the Soyuz-FG launch vehicle triggered the automated launch escape system. The spacecraft separated from the rocket and returned the crew safely to Earth under parachutes. The crew landed unharmed. Since April 2020, the spacecraft has been launched using the modernized Soyuz 2.1a rocket.
