Weather postpones SpaceX launch of supplies to space station Bad weather is keeping a SpaceX Falcon 9 rocket on the ground

CAPE CANAVERAL, Florida -- Storm clouds forced SpaceX to postpone its Wednesday launch of a capsule carrying supplies to the International Space Station.

The private firm only had a split second window to launch its Falcon 9 rocket carrying the Dragon capsule. Another launch opportunity is Thursday at 6:01 p.m. ET.

The capsule contains about 5,000 pounds of supplies and experiments, including a 3D bioprinter to make human tissue in orbit for research.
