“SpaceX plans to launch two paying passengers on a tourist trip around the moon next year using a spaceship under development for NASA astronauts and a heavy-lift rocket yet to be flown, the launch company announced on Monday. The launch of the first privately funded tourist flight beyond the orbit of the International Space Station is tentatively targeted for late 2018, Space Exploration Technologies Chief Executive Elon Musk told reporters on a conference call. Musk declined to identify the customers or say how much they would pay to fly on the weeklong mission, except to say that it is “nobody from Hollywood.”“
