British billionaire Richard Branson says his space tourism project keeps being pushed back and isn't sure of an exact date for the first launch.
He says it will be at least another 12 or 18 months before the Virgin Galactic venture can offer space travel to adventurers.
The founder of the Virgin Group met with students on his first visit to Poland on Wednesday, where he came to launch Virgin Academy, which will help young people kick start their own businesses.
