Elon Musk's SpaceX program plans to break another important barrier in private space flight Tuesday with the re-launch of a previously-used Block 5 booster just three months after its initial flight. In conjunction with the re-launch, SpaceX announced plans to shorten re-launch times for the Block 5 booster to less than 24 hours by 2019, which would further solidify SpaceX's dominance of the private space flight market? Private space flight companies have been involved in a technological arms race for years on a number of different fronts. One of the most important fronts is the development of an inexpensive reusable rocket booster system that can be used to launch satelites and manned craft into space.
