NASA: Russian flight controllers have been trying to make contact with the unmanned space freighter

Space station crew can manage without supplies carried by the spacecraft, NASA says

(CNN) An unmanned Russian spacecraft originally bound for the International Space Station will re-enter the Earth's atmosphere after flight controllers lost contact with it, American astronaut Scott Kelly said Wednesday.

The spacecraft that lost contact with flight controllers will re-enter the Earth's atmosphere in about a week, Roscosmos, the Russian Federal Space Agency, said Wednesday.

"Roscosmos (the Russian Federal Space Agency) announced that the Progress will not be docking and will re-enter the Earth's atmosphere," Kelly said from the space station.

The Progress resupply vehicle will come off its orbit and will begin its combustion in the atmosphere between May 5 and May 7, according to Roscosmos. The Progress vehicle does not present any danger to the International Space Station due to a significant difference in orbit, Roscosmos added.

The Russia space agency said it is working on its next supply flight to the ISS and expects to launch a new Progress ship in the third quarter of this year.
