"Landing has taken place", the text on a big screen located in the main hall of the center read.
Both employees of the center and guests who were present there burst into applause.
Russian cosmonaut Sergey Prokopyev, German astronaut Alexander Gerst, and NASA astronaut Serena Aunon-Chancellor have delivered to Earth the pieces of evidence that Russian state space corporation Roscosmos and investigators need for their probe into the microfracture found in the orbital module of the Soyuz MS-09 spacecraft in late August.
Earlier in December, the cosmonauts carried out a spacewalk to examine the hole in the spacecraft, found in late August. The cosmonauts cut off three pieces of micrometeoroid protection to take samples of the sealer and the surface surrounding the microfracture.
