Fuel leak halts Friday launch of space shuttle Discovery

CAPE CANAVERAL, Florida — A potentially dangerous hydrogen gas leak cropped up as NASA fueled Discovery for liftoff Friday, resulting in yet another delay for the space shuttle's final voyage — possibly until the end of the month.
It was the latest problem — and most serious — to hit NASA's oldest and most traveled shuttle over the past week.
Another attempt would not be made before Monday, NASA spokesman Allard Beutel said.
Midway through the fueling process Friday, hydrogen gas began leaking from the attachment point for a vent line on the external fuel tank. It's the same type of problem that forced delays for two shuttle missions last year, and had not reoccurred since then.
