The first commercial spacecraft to perform a mission to the International Space Station is set to launch on May 19th. Commercial space company SpaceX announced on Friday the new launch date for its Dragon space capsule.

The capsule atop the company’s Falcon 9 rocket was due to lift off from Cape Canaveral next Monday, but the launch was delayed to allow more work to be done on computer software for the mission.

The aim of the mission is to blast the Dragon capsule loaded with cargo into low-earth orbit before docking it with the International Space Station.

SpaceX spokesperson Kirstin Brost Grantham said Friday the company and NASA have nearly finished the software assurance process. “So far no issues have been uncovered during this process, but with a mission of this complexity, we want to be extremely diligent,” she said.

The backup date for the launch is May 22nd.
