Fyodor, the first humanoid robot to partake in a space mission, lost a chance to be named "the first robot to join the International Space Station crew" after the Soyuz MS-14 spacecraft carrying it, failed to dock with the station.
Fyodor was preparing for a second docking attempt scheduled on Tuesday morning, stated the NASA and Roscosmos.
On August 22, the Soyuz spacecraft embarked on a mission to the ISS, carrying Fyodor and its small companion.
Once it arrives to the ISS, the humanoid robot is supposed to start its tasks including sending measures remotely, determining the mission's safety signals and taking part in experiments that will be used while working in open space.
Two days after the launch, Soyuz reached the right orbit to dock with the ISS. However, a malfunction stopped it when it was only 60 meters away and prompted astronauts to keep it at a safe distance.
Three astronauts - Russian, Italian and American - have completed the necessary training before the second docking attempt.
The astronauts on board the station have relocated some of their units as part of preparations for the operation, which is supposed to end with Fyodor moving from Soyuz to the International Space Station, becoming the first robot to carry out missions within the station crew.
The Russian robot is supposed to stay there until September 7 before returning to Earth.
The manufacture of the robot Fyodor started in 2014. At the request of the Russian Ministry of Emergency Situations, it was later decided to train and develop it to be the first robot to partake in a space flight. Fyodor will also be used in the missions of the Federatsiya spacecraft being manufactured as part of the program of lunar manned flights.
