Update 11:30: The spacecraft has sucessfully launched but problems are delaying its power supply. Follow updates on our Autopia story.

Watch a live feed as SpaceX's Dragon capsule attempts to launch to the International Space Station carrying supplies and experiments. NASA's coverage starts at 5:30 a.m. PT/8:30 a.m. ET and, if all goes well, blast off is scheduled for 7:10 a.m. PT/10:10 a.m ET.

This will be SpaceX's third launch to the space station. The previous Dragon launch was mostly a success, though the failure of one engine meant that an experimental satellite it was carrying failed to reach orbit.

Among Dragon's cargo this time around is food for the ISS crew, computer hardware, and several experiments. The spacecraft is also bringing a special treat for the astronauts that was grown in the orchard of a SpaceX employee's father, said company president Gwynne Shotwell during a NASA press briefing on Feb. 28, though she didn't specify what fruit it was. This treat is similar to the previous SpaceX docking, when the company brought the ISS astronauts ice cream.

Though there is always the possibility of delay with any launch, weather forecasters predict an 80 percent chance of favorable conditions.
