NASA and SpaceX are now targeting Dec. 19 as the launch date for the next unmanned cargo run to the International Space Station (ISS) under NASA's Commercial Resupply Services contract.

The fifth SpaceX cargo mission was postponed from Dec. 16 to Dec. 19 to "allow SpaceX to take extra time to ensure they do everything possible on the ground to prepare for a successful launch," according to a statement from NASA.

The Dragon spacecraft will launch atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Both the Falcon 9 rocket and its Dragon spacecraft are in good health, according to NASA.

The mission dubbed SpaceX CRS-5 is slated for liftoff at 1:20 p.m.

An on time liftoff will result in a rendezvous with the ISS on Sunday. The crew would grapple the Dragon with the stations 57 foot long robotic arm at about 6 a.m.

US astronaut and station commander Barry Wilmore will operate the Canadarm2 to capture the SpaceX Dragon when it arrives Sunday morning. ESA astronaut Samantha Cristoforetti will assist Wilmore working at a robotics workstation inside the domed Cupola module during the commercial craft's approach and rendezvous.

The unmanned cargo freighter is loaded with more than 3,700 pounds of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear.

The Dragon research experiments will support over 256 science and research investigations for the six person space station crews on Expeditions 42 and 43.
