After months of delays, SpaceX is set to become the first commercial company to make a trip to the international space station with the launch scheduled for this weekend. On May 19, if all goes well, space X will launch its Falcon 9 from Cape Canaveral Air Force Station in Florida at 4:55 AM.
NASA TV will air the launch starting at 3:30 AM that morning. If anything should delay the launch a backup plan is to launch on May 22. Before the Dragon capsule attempts to dock with the ISS, it will be put through several tests including a simulated docking abort. If the capsule passes all the tests it will be allowed to dock, but if it fails the mission will be aborted.
