A Russian cargo spaceship has failed to reach the International Space Station (ISS) after experiencing technical difficulties.
Russia's space agency said they had lost contact with the Progress 59, which had blasted off from the Baikonur Cosmodrome in Kazakhstan earlier on April 28.
The cargo ship is carrying three tons of fuel, water, food and supplies for ISS.
Roscomos said there were problems with the spacecraft's communications antennas, and said it was working to eliminate them.
Roscosmos warned if it could not reestablish contact with the craft, it will eventually re-enter Earth's atmosphere and burn up.
The Russian space agencies said the crew aboard ISS had enough supplies, even if the latest Progress mission fails.
