NASA is fuelling space shuttle Endeavour again. The launch team began loading fuel into the shuttle for the second night in a row.
The three-hour-long operation began just as the Super Bowl was kicking off in Miami.
Endeavour is scheduled to blast off at 4:14am Monday (local time) on the last big space station construction mission.
Sunday's try was spoiled by thick, low clouds. Although more of the same is expected Monday, forecasters are going with a 60 percent chance of acceptable weather.
It is the last scheduled night launch for the space shuttle program, which is winding down after nearly 30 years. After this one, four more flights remain.
Endeavour's six astronauts will deliver and install a new room and observation deck at the International Space Station.
