Amazon billionaire Jeff Bezos has today announced a $3.4 billion plan to travel to the moon in a collaboration with NASA - and bizarrely said it will be "to stay".
In a tweet, Bezos said: "Honored to be on this journey with @NASA to land astronauts on the Moon - this time to stay."
NASA awarded Bezos and his private rocket firm a $3.4billion contract to take astronauts back to the moon, said NASA's exploration chief Jim Free on Friday, May 19.
