The latest battle for space is being waged by billionaires. Jeff Bezos with Blue Origin is up against Sir Richard Branson with Virgin Galactic. And it looks like Branson is going to beat Bezos into space, launching his reusable space plane Unity Sunday. Bezos will be going up a week later. Leo says it used to be the battle of who can build the biggest yacht. Now it's who launches in a spaceship. Meanwhile, Elon Musk has sold all his houses and is living in a trailer in Texas to oversee the development of the SpaceX Starship for a journey to Mars.
