Other materials include the ship's crew bringing many Earth samples to help technicians explain the origin of a hole that caused air leakage in the Russian parts and the International Space Station (ISS) on August 30.
The hole had drilled almost inside the Soyuz MS 09, which was dumped to the orbital station in last June, and sealed with patches.
An internal commission created by Russia's Russian energy engineering corporation Energia (manufacturer of the ship) excluded the manufacturing deficit as the potential cause of the hole.
On 11 December, Russian Kosmonau Oleg Kononenko and Sergei Prokópiev, who work in the ISS, made space to explore the outer surface of the Soyuz.
The cosmonauts broke two pieces of protection against micrometeorites, and took samples of the substance used to seal the hole and stored in a container that returned to the Earth on Thursday.
