As NASA marked the 50th anniversary of the historic first Moon landing, the US space agency is preparing to take its next giant leap with the ambitious Artemis programme that could see the "first woman and the next man" walk on the lunar surface.
Artemis is named after the twin sister of Apollo who is also the Goddess of the Moon and the hunt.
NASA said the mission "encompasses all of our efforts to return humans to the Moon -- which will prepare us and propel us on to Mars."
