Judging by the excited faces of SpaceX employees after the live webcast, everything went perfectly. Dragon, the world’s first orbital space capsule built by the private sector, will now orbit the planet a few times over the next couple of hours before splashing down in the Pacific. It is a small but significant milestone. The unmanned demonstration mission wants to prove that Dragon is able to deliver crew and cargo to the International Space Station. The reason for all the excitement is that the working capsule really points the world firmly in the direction of greater involvement by the private sector in providing trips to space.
