Second time's a charm.
The SpaceX Falcon 9 rocket blasted off from Cape Canaveral Air Force Station early Tuesday morning, carrying the Dragon capsule payload that, if all goes according to plan, will dock with the International Space Station later this week.
This is the first time a private company has attempted to berth a spacecraft with the International Space Station.
This was SpaceX's second attempt to launch the Falcon 9 rocket. A launch planned for early Saturday morning was aborted after abnormally high pressure was detected in one of the engine's combustion chambers, causing the computers to automatically shut down the rocket's nine engines less than one second before liftoff.
Over the next several days, the Dragon spacecraft, which separated from the rocket's second stage fewer than ten minutes after launch, will orbit Earth and undergo maneuverability and system tests to make sure it's fit to dock with the space station.
Then, with NASA's approval, the Dragon capsule, which is carrying about 1,000 pounds of food, clothing and water, will attempt to dock with the ISS on Friday.
“We obviously have to go through a number of steps to berth with the Space Station, but everything is looking really good and I think I would count today as a success no matter what happens with the rest of the mission,” Elon Musk, the CEO and Chief Designer of SpaceX, said at a news conference following the launch, according to press materials.
The flight is a trial run for SpaceX's plan to deliver cargo, and eventually crew, to the space station. The mission is partially funded by NASA's COTS (Commercial Orbital Transportation Services) program, and the firm has a NASA contract to fly 12 delivery missions to the outpost once test flights are completed.
NASA awarded $381 million to SpaceX as part of a 2006 agreement, according to press materials from the company. SpaceX has spent $1 billion over the last decade, according to the Associated Press.
NASA has also awarded $266 million to Orbital Sciences Corp., a Virginia-based space technology company, which has a goal of launching a rocket and spacecraft by the end of the year.
"Congratulations to the teams at SpaceX and NASA for this morning’s successful launch of the Falcon 9 rocket from Cape Canaveral Air Force Station in Florida," John P. Holdren, Assistant to the President for Science and Technology, said in a statement after the launch. "Every launch into space is a thrilling event, but this one is especially exciting because it represents the potential of a new era in American spaceflight."

Private rocket maker SpaceX aimed for a Tuesday liftoff after fixing the engine problem that caused a launch abort over the weekend. If launched Tuesday, May 22, the Dragon will reach the space station Thursday and undergo a series of practice maneuvers from more than a mile out. Then on Friday, the capsule will fly within reach of the station's 58-foot robot arm, which will snare it and berth it to the orbiting lab. The arm will be operated by astronauts Pettit,and Kuipers, two of the six station residents. (AP Photo/NASA/European Space Agency)

The first commercial cargo run to the International Space Station has been delayed again for more software testing. Space Exploration Technologies Corp., better known as SpaceX, was aiming for a Monday, April 30, 2012, liftoff of its Falcon rocket and Dragon capsule. But on Wednesday, May 2, the California-based company announced its latest postponement and said a new launch date had not been set. (AP Photo/NASA, Kim Shiflett)
