The US President has ordered NASA to plan a new manned mission to the Moon, 45 years after the last one - Apollo 17.
Donald Trump has signed a policy directive "to lead an innovative space exploration programme to send American astronauts back to the moon, and eventually Mars".
White House spokesman Hogan Gidley made the announcement which was followed by a speech by Mr Trump.
He was joined by one of the first men to land on the Moon, Buzz Aldrin, and Harrison Schmitt, known as "Jack", who is the last living crew member of the Apollo 17 mission, which landed in 1972.
