A technical problem has delayed for at least 24 hours the scheduled launch Tuesday of an Ariane rocket carrying supplies to the International Space Station (ISS), space officials said.
"During final countdown one of the authorization parameters went red," said Jean-Yves Le Gall, president of the Arianespace rocket launch company said.
"From what I was told there was erroneous data coming from a fuelling system."
The modified Ariane-5 rocket had been scheduled to blast off from the European Space Agency's launch center in Kourou, French Guiana, on the northeast of South America, at 7.13 p.m. local time (2213 GMT).
Aboard the rocket was the 20-tonne Johannes Kepler automatic transfer vehicle (ATV) that is designed to deliver supplies to the ISS after an eight-day flight.
