HOUSTON, TX (Catholic Online) - "Looks like we got us a dragon by the tail," Pettit told mission control in Houston as the room erupted with cheers. 

The docking process is a lengthy procedure and will take most of the day on Friday to complete. The crew is expected to open and enter the capsule tomorrow. 

The two spacecraft will remain docked for almost a week. Next Thursday, the Dragon capsule will detach from the space station and splash down in the Pacific Ocean off the California coast where it will be retrieved by ship. 

The SpaceX Dragon mission is a milestone because it represents a significant private foray into space exploration, something that until now has been the domain of world governments. However, in the past decade there has been a substantial movement to hand off routine spaceflight tasks to private industry allowing NASA to focus on exploring deep space and evaluating possible missions to the Moon and Mars. 

If the SpaceX Dragon mission proves successful, NASA will likely give permission to start ferrying supplies back and forth to the ISS using the capsule. Eventually, astronauts will fly in the capsule. 

The development of the Dragon capsule and its use is important to NASA because since the retirement of the Space Shuttle, NASA has no way of getting astronauts to and from space, unless it rents space on Russian rockets. 

SpaceX still has a number of other hurdles to clear before NASA gives the go ahead to fly astronauts, but everything appears to be working properly. Last week, just seconds before launch, the rocket aborted because of a sensor reading. That incident resulted in the replacement of a valve and the rocket flew a few days later. 

So far, everything appears to be working out just fine between NASA and SpaceX - good news for the future of both programs.
