The US space agency has cancelled Saturday's launch of the shuttle Endeavour due to a hydrogen leak, a Nasa spokesman announced.
The launch had been scheduled for 7:17am (1117 GMT) from Cape Canaveral in Florida.
"The launch is scrubbed, it's official," spokesman Kyle Herring told reporters, adding that the postponement was likely to last at least 24 hours.
Meanwhile, the National Aeronautics and Space Agency said in a statement posted on its website that the leak was detected near the Ground Umbilical Carrier Plate, which is attached to the external tank at its intertank area.
The leak was similar to one that occurred during the first launch attempt of the space shuttle Discovery in March.
After the leak is assessed, shuttle managers planned to meet Saturday to discuss what steps to take next, including targeting a new launch date for Endeavour's mission to the International Space Station, Nasa said.
