If at first you don't succeed, maybe on the third try you will. That seemed to work for SpaceX when it successfully landed a Falcon 9 rocket last month but on solid ground. Now it will be tempting fate once more and will be daring to land another Falcon 9 rocket at sea using one of its drone platforms. Perhaps it feels that lady luck, not to mention science, will be on its side this time around. If successful, SpaceX would take yet another momentous step forward in making space exploration, and space travel, more economical and ultimately more affordable.
