The launch was carried out from the Gagarin’s Start of Baikonur, a Roscosmos representative told Sputnik earlier in the day, adding that the upgraded Soyuz spacecraft is carrying 70 kilograms (154 lb) of food products.
The toy on a string that can be seen in front of the cosmonauts is a zero-gravity indicator.

The Soyuz MS-04 spacecraft has an upgraded navigation system, new communications system and a modernized docking system. The spacecraft also has a larger solar cell area, which enables it to generate more energy.
The launch of the Soyuz MS-04 to the ISS was initially scheduled for March 27 but was postponed to conduct more safety checks.
