Endeavour fueling up for Monday launch

BEIJING, Feb. 8 (Xinhuanet) -- NASA began fueling the space shuttle Endeavour for a morning launch after the Sunday attempt was disrupted by the low clouds over Florida's Kennedy Space Center, according to media reports Monday.

The space shuttle and its six astronauts are to blast off at 4:14 a.m. on a 13-day trip to install the last two main pieces of the International Space Station.

According to NASA spokesman George Diller, there was only a 60 percent chance of acceptable weather for launch.

Scattered clouds threatened visibility, though "there is some possibility that could improve over the course of the evening," Diller said. "We're cautiously optimistic that the weather will go our way."

Endeavour has been scheduled to lift off on Sunday morning, on a 13-day construction mission to the orbiting International Space Station (ISS). Endeavour's mission will deliver and assemble Node 3, the last U.S. module, onto the ISS, giving the laboratory a room with quite a view.

The mission will kick off the final year of shuttle flights, with five missions planned through September.
