The first four SpaceX test flights ended in explosions but the upgraded Starship went vertical just in time for landing on Wednesday, having soared more than its planned maximum altitude of six miles over the Gulf Of Mexico. SpaceX has finally nailed a test flight of the rocket ship that tech billionaire Elon Musk wants to use to send people to Mars. A first orbital Starship flight is planned for the end of the year and Mr Musk has said he wants to fly Japanese billionaire Yusaku Maezawa around the moon in 2023. What is next for humans to live in mars ?
