Another delay for space shuttle Atlantis.
NASA has called off Wednesday's planned lunchtime launch because of a fuel cell problem. Fueling of the shuttle never got underway Wednesday morning before one of three cells providing electricity
malfunctioned. NASA will try for lift-off again Thursday.
Atlantis was supposed to launch August 27th but that was put off by a lightning strike, then the approach of Tropical Storm Ernesto.
The shuttle is to carry two girders that are crucial to the construction of the international space station. Astronauts will carry out three spacewalks to attach the girders and solar panels to the space station.
