The European Space Agency says it's delaying its unmanned mission to Mars until 2016 and may seek help from Russia and the United States.
It is the second big delay for the ExoMars Rover — Europe's flagship space mission, the BBC reported Saturday, noting the launch already had been pushed back from 2011 to 2013 because of difficulties with the early stages of the mission's design.
European governments have asked the Space Agency to find ways to reduce the $1.6 billion project, including seeking financial and technical help from Russia and the United States, said agency spokesman Franco Boncina.
"This way we could retain the full splendor of the mission and not reduce its scientific capability," said Bonacina.
