ST. PETERSBURG, October 2. /TASS/. Russia’s space agency Roscosmos said on Thursday that the special commission is due to announce next week the cause of Soyuz TMA-14M spacecraft’s solar battery glitch.

“Technically this is clear to us, but now a commission is working and we want to find out what caused this incident,” Roscosmos chief Oleg Ostapenko said.

The Russian-built Soyuz capsule carrying two Russian cosmonauts and one NASA astronaut reached the International Space Station (ISS) early on September 26, despite a struck solar battery that failed to deploy just after its launch from the Baikonur spaceport.

Despite the emergency situation, the crew managed to implement a six-hour scheme docking with the station. The crew had sufficient energy in the battery of the vehicle for rendezvous and docking.

The faulty solar battery finally unfolded after the spacecraft berthed with the ISS.
