An unmanned spacecraft carrying Russia’s first humanoid robot to be sent into orbit failed to dock automatically at the International Space Station on Saturday, in a new setback for Moscow. “Russian cosmonauts issued a command to abort the automated approach of an uncrewed Russian Soyuz spacecraft to the International Space Station,” the US space agency NASA said in a statement. “The craft was unable to lock onto its target at the station,” and “backed a safe distance away from the orbital complex while the Russian flight controllers assess the next steps,” NASA said. Russian flight controllers had told the ISS crew it appeared the problem that prevented automated docking was in the station and not the Soyuz spacecraft, NASA added. Moscow news agencies quoted the flight centre control as saying the Soyuz craft had to retreat to a “secure distance” from the ISS. The docking had been scheduled for 0530 GMT but a live broadcast of the event on the website of the Russian space agency Roscosmos was interrupted when the Soyuz approached to about 100 metres (100 yards) off the ISS. “The Soyuz is on a safe trajectory above and behind the space station that will bring it in the vicinity of the orbital complex again in 24 hours and 48 hours,” NASA said. “Russian flight controllers have indicated the next earliest docking attempt could be Monday morning.” TASS news agency quoted the head of the Russian side of ISS, Vladimir Soloviov saying “telemetry analysis showed there were failings with radio equipment” on the station. “It can be corrected,” he said, adding that part of the equipment would be replaced and another attempt at docking made between 0500 GMT and 0600 GMT on Monday. “There is no threat to the station and its crew,” a Roscosmos statement said.
