Antenna fails to deploy on unmanned spaceship bound for ISS

A unmanned Russian Progress spaceship racing to the ISS with 2.5 tonnes of cargo on board failed to deploy a key antenna that helps it dock with the orbiting lab, the Russian and US space agencies said.

"One of the antenna that provides for the ship's docking to the International Space Station failed to deploy," a Russian mission control official told Interfax. NASA tweeted that "Russian ground controllers are assessing a fix."
