Russia said on Thursday that it has lost track of a $265-million telecommunications satellite.

On Friday, Russia replaced Anatoly Perminov, the head of its space agency, after being reprimanded over a failed satellite launch in December.

Anatoly Perminov, the head of Roscosmos, Russia’s space agency, has announced he will be stepping down as he has reached the mandatory retirement age of 65 allowed for state officials.

Three members of the International Space Station (ISS) crew set to depart for a return trip to Earth on Friday will be forced to wait another day due to issues encountered while trying to undock.

The head of the Russian space agency said Wednesday that the country is considering sending a spacecraft to a large asteroid to knock it off its path and prevent a possible collision with Earth.
