[Updated 4:18 am EDT] (CNN) - The SpaceX Falcon 9 rocket blasted off from Cape Canaveral, Florida, early Tuesday carrying the first private spacecraft bound for the International Space Station.
The company's Falcon 9 rocket - with its Dragon capsule filled with food, supplies and science experiments - is scheduled to blast off at 3:44 a.m. ET from Cape Canaveral, Florida.
The first attempt at launching the rocket was halted Saturday when a flight computer detected "high pressure in the engine 5 combustion chamber," according to the company.
"During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine," the company said in a statement Monday. "The failed valve was replaced on Saturday, and after thorough analysis, the vehicle has been cleared for launch."
