The Space-X spaceport is about twenty minutes from our home. We drove out there today to see the latest prototype of the starship that will take humans to Mars. Her name is SN-9. She could fly next week. They have been test firing her engines and doing pressure tests on her for several days. Many of her predecessors did not survive the tests leading up to a launch. One reason is that some of the tests were designed to find out how much pressure the ship could handle.
